NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 1-1 DS000034 Unclassified 1. Introduction Cobham Surveillance domo has been supplying point to point high data rate digital video links for many years to security users. These links exhibit exceptional performance, enabling users to reliably exchange video data in extremely difficult RF transmission environments such as mobile links and links in dense urban areas. More recently domo has seen an increasing requirement to use the rugged transmission capabilities of COFDM to carry general purpose IP traffic. There is now also a growing demand from domo customers to incorporate bi-directional capability in its solution, and also a MESH capability. The traditional two frequency approach (Frequency Division Duplex or FDD) to enable bi-directionality is not convenient or appropriate in many applications; the use of separate frequencies makes frequency management difficult. Also FDD adds complexity, cost and weight with additional antennas, amps and circuitry. The solution to this problem is a single frequency approach (Time Division Duplex or TDD) where all communicating nodes share the same frequency. This simplifies frequency management and circuitry implementation. 1.1. MESH Applications  Rapid deployment temporary surveillance  Mini and Micro UAV communications.  Radios to connect surveillance team vehicles.  Special Forces data radios.  Military vehicle radios.  True real time surveillance / pursuit where an ad-hoc network is used relay imagery in a fluid environment. This would apply equally to manned surveillance as to vehicle pursuit.  Next generation Unmanned Ground Vehicles (UGVs) where vehicles operate co-operatively.  FIST battlefield communication applications.  Perimeter security applications. Each MESH NETNode has two Ethernet interfaces to allow flexibility of connection. This, in conjunction with the radio link, provides the same functionality as a switched Ethernet hub. The radio technology is based on the fundamentals of the acclaimed domo Solo4 rugged, robust and reliable transmission system giving an extremely secure and easily deployable bi-directional communication system. AES BCRYPT1 encryption/decryption (AES128 & 256) is also supported on both forward and reverse paths of the MESH system. AES support is an optional software feature and may require an export license.

NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-9 DS000034 Unclassified Mesh could also be used to quickly deploy a multiple node surveillance system around an area of interest. The NETNode units could be used to contribute Video or IP data such as stills photography or sensor data. The NETNode can accept video from a standard composite (PAL/NTSC) camera or an IP camera can be connected through the MESH Network. To connect a standard composite video signal into a MESH NETNode the NETNode-AVI-UP option must be fitted into the NETNode. The MESH is able to support 3 or 4 full quality video links through the one frequency – if 3 nodes were to contribute video simultaneously then the bit-rate for each link would have to be adjusted to roughly 700kbps per video service. Full frame rate video can be supported at 700kbps but at reduced resolution – typically ½ resolution or SIF resolution would be selected. Higher resolutions could also be supported – even up to full resolution but typically not at full frame rate. A 4 or 5 Node Mesh network (when configured to operate in 3.5MHz bandwidth mode) can have up to 3Mbps of data capacity available for transmission of information between the Nodes IF every Node can see every other Node and the link quality between all the nodes is good. Note that if information needs to be transmitted through a chain of Nodes or if the link quality is not good then the useful information rate available in the Mesh reduces. NOTE: Some Phase 2 Mesh Nodes (4.4 to 5GHz) units and post Sep 2010 delivery (2.17 to 2.50GHz) Mesh NETNodes can support a 5MHz bandwidth that allows up to 5.5Mbps of useable data in the Mesh Network. To discover if your unit supports 5MHz bandwidth you can look at the Board Type in the Information Pane of the web browser interface. See Section 4.12 Information Tab for details on how to discover the Board Type.

BEFORE SWITCHING ON THE UNIT PLEASE NOTE: The DC power supply must be set to 12.5V and assume up to 2.5A of current draw. 2.6. Establishing Connection to a Node Once a user has connected to a unit and established a NETNode on their network operating the system is easy. The procedure to establish communication with a node varies depending on whether the User wishes to connect the MESH to a network running DHCP or whether the user wishes to run with static IP addresses. If your network has no DHCP server you will need to assign a fixed IP address for the NETNode using a serial RS232 interface. If you have a DHCP server the NETNode will automatically acquire an IP address and you can connect straight via IP. You may still wish to change the DHCP IP address to a fixed IP address using the browser. 2.6.1. Connecting the NETNode to your Computer using Serial (RS232) The first time you set up a NETNode with no DHCP you‟ll be connecting using a serial RS232 interface. You‟ll only have to do this once – every other time you‟ll hook up to the NETNode using an IP interface using a web browser. On a Phase 1 Unit 1. Connect the Amphenol 19-way plug (m) from CA0288-5 cable to the Amphenol 19-way jack (f) on the NETNode labelled CTRL/DATA.

Caution: There are two D-Type 9-way plugs on the CA0288-5 cable – ensure you select the RS232 version by checking the label attached to the shell of the plug. The other is RS485. On a Phase 2 Robust Unit 3. Connect the Amphenol plug (m) from CA0406 cable to the Amphenol jack (f) on the NETNode labelled CTRL/DATA. 4. Now, connect the RS232 D-Type 9-way plug (f) to your computer‟s RS232 9-way jack (m). 5. Caution: There are two D-Type 9-way plugs on the CA0406 cable – ensure you select the RS232 version by checking the label attached to the shell of the plug. The other is RS485. On a Phase 2 Plain box Unit 6. Connect the 15-way HD D-Type plug (m) from CA0474 cable to the 15-way D-Type jack (f) on the NETNode labelled AUX. 7. Now, connect the RS232 D-Type 9-way plug (f) to your computer‟s RS232 9-way jack (m). 8. Caution: There are two D-Type 9-way plugs on the CA0474 cable – ensure you select the RS232 version by checking the label attached to the shell of the plug. The other is RS485. 2.6.2. Starting the Control Software The procedure to establish communication with a node varies depending on whether the network is running a DHCP server or whether the user wishes to run with static IP addresses. If the network is running DHCP and the NETNode unit is set to defaults, the unit will acquire an address via DHCP. To find out the IP address a PC running the Node Finder PC application must be connected to the same network as the Mesh NETNode. Starting the Nodefinder application will identify the IP address of any and all mesh nodes on the Network. To find out which unit this is unplug the IP connection to the unit and refresh Node Finder (F5). The entry that disappears is the node in question. If the User‟s Network does not support DHCP or the unit has the wrong fixed IP address, then a PC running the Node Finder PC application must be connected via RS232 using the data cable (CA288 (Phase1) or CA0406 (Phase 2 Robust) between the port on the PC and the Control port on the MESH node. On a Phase2 Plain box Mesh connect the PC to the AUX port using the CA0474 cable. The RS232 control 9-way D-type must be used.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-14 DS000034 Unclassified To set the IP address via RS232 select the correct PC RS232 port from the tools->network setting menu. If the NETNode unit is connected to a network that supports DHCP then leave the DHCP option box checked. If the network does not support DHCP then a valid static IP address must be entered and the DHCP box unchecked. Note: Click „Apply‟ after changing any configuration setting Select Ethernet or RS232 IP address of any unit on the Network
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-15 DS000034 Unclassified Once a valid IP address is set it may also be changed in the WEB browser. Now that the IP address is established the web-server should be used to configure frequency and output power. Once the node is on the User network any Web-browser can be used to browse to the Mesh NETNode to configure and control the node or to browse network status. The unit can be browsed by entering the relevant IP address in the web-browser. 2.6.3. Connecting the NETNode to your Computer using IP For the rest of the set up of the NETNode you‟ll be connecting using an IP interface and a web browser. On a Phase 1 Unit 9. Connect the Amphenol 19-way plug (m) from CA0288-5 cable to the Amphenol 19-way jack (f) on the NETNode labelled CTRL/DATA. 10. Now, connect the RJ45 8-way plug (m) to your computer‟s RJ45 8-way jack (f). On a Phase 2 Robust unit 11. Connect the Amphenol plug (m) from CA0403cable to the Amphenol jack (f) on the NETNode labelled Power/IP. (This cable also includes the DC power banana plugs.) 12. Now connect the RJ45 8-way plug (m) to your laptop‟s RJ45 8-way jack (f). 13. Ensure you know the IP address of the computer you have attached.

Repeat the procedure for a second node – making sure that the frequency is always set to be identical. Domo suggests configuring the system on the bench as outlined below. BEFORE SWITCHING ON THE WHOLE SYSTEM PLEASE NOTE: The DC power must be set to 12.5V and assume up to 2.5A current draw. Don‟t connect the Ethernet ports of both units simultaneously to your network when they are both operating as you will create a loop in and out of your IP network. This may affect your network performance and prevent access to either node for about 1 minute. Connect one MESH node unit to your network and the other MESH node to an IP camera or a standalone PC. The IP Camera or the standalone PC will then be connected to your network through the MESH network. 2.8. DC Power The NETNode can be powered from a nominal 12V DC supply or an AC to DC adapted supply. Locate, push and twist to lock the Amphenol connector on the Power cable into the socket labelled POWER, taking care to align the connectors. Connect the banana connectors on the other end of the cable to a suitable DC source. The 12V DC input has the following characteristics.  Input Voltage Range – 12V to 15V, not reverse voltage protected on Phase 1 Units  Current draw – 1.2A to 2A at 12V (capacity dependant), the power draw is very dynamic and you should use at least a 2.5A rated supply.

Both antennas must be connected for normal operation. The units are supplied with different types of panel mounted connectors. The phase 1 units are supplied with panel mounted TNC connectors which carries the RF input and output. The antenna should be connected by screwing it onto the TNC, but care should be taken to not over tighten the connector. The phase 2 plain box mesh units are supplied with panel mounted SMA connectors which carry the RF input and output. The antenna should be connected by screwing it onto the TNC, but care should be taken to not over tighten the connector.

Some of the antennas will require connector adaptors (Inter series RF adaptors) to connect the antennas directly to the product. 2.13. Deploying the System All external connection to the MESH products should be made, as described in the previous sections, before proceeding to power on the system. 2.13.1. Installation Notes This section gives guidelines for how to install the MESH node in the following applications. 2.13.2. Fixed position Applications The Phase 1 and Phase 2 robust NETNode units are designed to be waterproof allowing them to be installed outdoors. 2.13.3. Vehicle Applications Interconnection between the unit and any antenna should be kept as short as possible, but where this is not possible, special attention should be taken to use only low loss cables. An appropriate cable might be RG213C/U. It is essential to minimise the distance between the unit and the antenna. Mounting holes are provided. Power conversion will be required for 24V vehicles. The video input can be connected across long video cable lengths so remotely mounted cameras should pose no problem. The unit is self-cooling; however it should be mounted in a ventilated environment. Forced air cooling is not required.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-22 DS000034 Unclassified 2.13.4. Diversity and Antenna Positioning The domo MESH NETNode product uses an advanced diversity technique called maximum ratio combining to construct a good spectrum from two potentially damaged received signals. This requires a small separation of the antennas. Sometimes better results can be achieved by separating the antennas further. The optimum antenna placement depends on the environment in which the equipment is used and the signal path, and is often limited by physical factors (accessibility for example) as well as cable loss. Note: Any cable run between the Node and the antenna MUST be LOW LOSS cable. Contact domo for details of suitable cable. Note that a cable suitable for use at 400MHz will not necessarily also be suitable for use at 5GHz.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-23 DS000034 Unclassified 2.14. Battery / DC Power Considerations The Phase 1 MESH NETNode units can consume over 2A of current at 12V. Phase 2 NETNodes typically do not exceed 1.5Amps of current consumption at 12V nominal supply voltage. They are designed to trip off at 10.5V and reset on at 11.5V. The DC cable supplied as standard with the MESH node is 5m long to allow a customer to mount the NetNode on a mast. This suffers about 0.5V drop through the cable. Therefore 1W MESH nodes need to be connected to a large capacity battery which in nominally 12V or to a 12V power supply. AC to 12V power supplies are not supplied as standard with the product. Users can order a suitable universal AC to 12V power supply from domo as a cost option.

The transmitter only sends when it has data ready to move. For a unit to function in a mesh the transmitter must be enabled. 3.3.2. About Frequency All the units in a mesh must be on the same frequency. Check that the Frequency is valid for the operation of the unit – specific country regulations will determine the frequencies available for operation. 3.3.3. About Channel Bandwidth All units in a mesh must have the same bandwidth set. The options are 2.5, 3 and 3.5MHz. As the bandwidth increases the bit-rate available in the Mesh increases in proportion to the bandwidth. November 2010 units may have an additional 5MHz bandwidth mode. 3.3.4. About Mesh ID The Mesh ID tells the unit which mesh it belongs to. All NETNodes on Mesh ID 122 for example will communicate with each other. This means you could set up another mesh with Mesh ID 125 for example on the same frequency which would run independently of Mesh 122. However the Meshes will only work reliably if the separation is sufficient to avoid NO interference. Operation of two mesh systems on the same frequency should be avoided. You can choose any numbers from 001 to 255 for your Mesh ID. 3.3.5. About Node ID The Node ID gives the unit a unique ID within the mesh. You can have up to twelve NETNodes in a mesh and they each must carry a unique Node ID. You can choose any numbers from 0 to 11 for your Node ID. A node may automatically reassign its‟ Node ID at power up if it finds a conflict with an existing node.

An image from the camera will be displayed. 5. If your network camera has PTZ capability, you‟ll be able to control it using the software on the computer. Note: You will view or listen to most assets in a similar way depending on the device being used. Each IP device will have its own control software but is usually accessed by using a web browser.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-32 DS000034 Unclassified 3.7. Connecting a Composite Camera to a NETNode If you have an AVI version of the NETNode you can attach a composite camera to the unit. The composite camera can be PAL or NTSC. You‟ll need a fully powered mesh system which has completed forming a mesh automatically and is showing a solid green RF Connected LED on each NETNode. The NETNode must be configured for composite camera operation. Check that Global Settings → Auxiliary Address is set to 1. On a Phase 1 Unit You‟ll also need for the composite camera with a BNC Jack a CA0286-3 cable. 1. Connect the Amphenol 10-way plug (m) from CA0286-3 cable to the Amphenol 10-way jack (f) on the NETNode labelled AV. 2. Now connect the BNC 2-way plug (m) to your camera‟s BNC 2-way jack (f). On a Phase 2 Robust Unit You‟ll also need for the composite camera with a BNC Jack a CA0477 cable. 1. Connect the Amphenol plug (m) from CA0477 cable to the Amphenol jack (f) on the NETNode labelled AV. 2. Now connect the BNC 2-way plug (m) to your camera‟s BNC 2-way jack (f). 3. The CA0477 cable also provides a DB-9 socket that carries RS232 data from the NETNode that can be used to control a Pan Tilt Zoom (PTZ) camera PTZ control is required. On a Phase 2 Plain box Unit You‟ll also need a composite camera with a BNC Jack and a CA0122 cable. 1. Connect the 5-pin Lemo plug (m) from CA0122 cable to the Lemo 5-way jack (f) on the NETNode labelled A/V. 2. Now connect the BNC 2-way plug (m) to your camera‟s BNC 2-way jack (f). 3. The AUX connector can provide RS232 or RS485 data to control PTZ functions, if required. 3.7.1. Integrated Video Encoding AVI option fitted (Composite Input) The user must enable the video transmission. If the MESH node has an AVI option fitted then it will accept standard composite video (NTSC or PAL) and it will encode and stream the video over the Network. An Encoder Tab appears on the Web-browser if an internal video encoder is fitted.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-33 DS000034 Unclassified The user can select from a number of preset Encoder options Using the advanced options the user can more precisely customise the encoder settings. Please refer to chapter 5 Streaming over IP for details on how to configure the NETNode to stream this encoded video and audio data to a destination on the network. Note: Click „Apply‟ after changing any configuration setting
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-34 DS000034 Unclassified 4. Advanced Procedures 4.1. Status Tab – Overview Pane Now you have got the NETNodes configured, let‟s take a look at the rest of the configuration possibilities. We‟ll begin with the Status tab. Here is the Status tab with the focus on the Overview pane. 4.1.1. Node ID We are showing six NETNodes with Node IDs of 1, 2, 4, 5, 6 and 7. There could be up to twelve NETNodes in a mesh with Node IDs numbered 0 to 11. 4.1.2. Unit Name The unit name is a „friendly‟ name to make it easier for you to know which NETNode we are talking about. This name is assigned in the Global Settings Tab. 4.1.3. IP Address This shows the IP address of the unit that we set up in our initial configuration. Notice that it is shown as a hyperlink. If you click on one of these hyperlinks the browser will switch to that NETNode. 4.1.4. Battery Voltage This returns the current battery voltage of the NETNode. Not so exciting when we are on mains in the lab but vital when you are looking at a node located on a high building several miles away which is running on batteries.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-35 DS000034 Unclassified 4.1.5. Show Details Check Box If you check this box you‟ll see a whole bunch of data about Tx IP Packets etc. This can give you vital information about the running of the network. 4.1.5.1. Tx IP Errors Zero unless the node in question has too much data to send. 4.1.5.2. Number of tokens This is the number of token passes in a 2 second interval that the node performs. This higher this number the more data that node can transmit. 4.1.5.3. Number of TX retries Number of times a token needs to be retransmitted from the node in question. This should all be zero for a working system. 4.1.5.4. Number of RX fails Number of times the node does not receive a decode-able transmission. This can be non zero if a node does not see another node properly in the system. This may be indicated by red signal strength. Forwarding allows data to be passed between nodes that have a poor link using other nodes in the system. 4.1.5.5. Show deltas When ticked all numbers show the parameter over a 2s internal. When not ticked the numbers are accumulative and updated every 2s. A non zero number indicates a problem with that node (such as antenna position or interference), and should be corrected as it will drastically reduce system throughput.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-36 DS000034 Unclassified 4.1.6. Signal Quality This gives you a simple picture of the signal quality around the mesh system. Ideally, we‟d like to see steady green boxes for all links. Naturally, mobile units will go out of range or interference will cause a unit to degrade for a while. One of the clever things about the mesh is its ability to find a new routing and heal itself thus keeping your network on air. Here‟s what the colours mean: Colour Means… Green 16 QAM mode – most robust Amber QPSK mode – less robust Red Basic link only – lowest data rate passing between nodes White Link broken or not configured Note that a Red link will not guarantee IP data between nodes. For example the link between node 0(TX) and node 4(RX) is currently Amber. 4.1.7. SNR This pane shows the Signal to Noise Ratios for each of the NETNodes. For good quality links this should be in excess of 17dB. 4.1.8. Level A This pane shows the dBm value for antenna A on the NETNode unit. 4.1.9. Level B This pane shows the dBm value for antenna B on the NETNode unit.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-37 DS000034 Unclassified 4.1.10. IP Rx Errs This pane shows the number of IP receive errors for each NETNode. It is worth checking that the received signal levels on both antennas are similar. Very different readings from the inputs can indicate a faulty antenna which should be replaced.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-38 DS000034 Unclassified 4.2. Status Tab – Spectra Pane Now let‟s look at the Status tab with the focus on the Spectra pane. 4.2.1. About the Spectra Displays There are two displays labelled A and B which show the spectra being received on the two diversity antennas of the NETNode you are attached to. But, there could be several NETNodes transmitting on the mesh so we need to define which unit we are looking at. This is done with the radio buttons on the left side of the spectra display. In our example, the radio button for Domo Office is selected. This means the two displays are showing spectra for the Domo Office NETNode transmissions as received on our node‟s two antennas. 4.2.2. Interference The last radio button is called interference. When you select this, the displays show the spectra when none of the NETNodes in the mesh are transmitting. This enables us to look for interference on the frequency we are planning to use for our mesh.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-39 DS000034 Unclassified 4.3. Status Tab – Maps Pane 4.3.1. Radio Buttons The radio buttons enable you to choose between Network and one of four map displays for the mesh. Leave it on Network for now. 4.3.2. Node Information Under the radio buttons you‟ll see some node information about the NETNode you are currently attached to. We talked about this information in the Overview Pane above. 4.3.3. GPS Information The NETNode we have selected has a GPS unit connected and the Use GPS check box is checked. This means that the NETNode can broadcast precise information about its location to other nodes or fixed assets on the mesh (assuming that the GPS is locked to the GPS satellite transmissions).
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-40 DS000034 Unclassified 4.3.4. Show Details Check Box When the Show Details check box is checked the node information shown above is expanded to show the information listed in the 4.1.5 Show Details Check Box section of this manual. Only the details for the selected Node are displayed. 4.3.5. Network Display In the example above you can see the network display is selected. This gives a simple graphical view of the NETNodes in the mesh and the links between them. Note: The buttons above the display are greyed out as they have no function when the Network radio button is selected. Each NETNode is shown as a circle with a white number. (If the number turns red, then the node is temporarily congested). If you have the Show Names check box checked, you‟ll also see the node name displayed. The links between the nodes are shown as coloured lines. As each NETNode supports bidirectional operation there are normally two lines for each link. Colour Means… Green 16 QAM mode – most robust Amber QPSK mode – less robust Red Basic link only – lowest amount of data passing White Link broken or not configured In the example above you are seeing static lines but when you are connected to a live system, you‟ll see these lines changing state and the RF environment changes or NETNodes move about.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-41 DS000034 Unclassified 4.3.6. Map Display Now select one of the numbered radio buttons. This changes the display to the map display. There are four possible map displays each selected by a radio button. Refer to section 4.3.9 Upload Map Data to learn how to put maps into the units prior to use. You‟ll see the mesh network diagram overlaid onto a map of the area showing the nodes and the links between them. There are two ways you can place the nodes onto the map:  Manual Placement  GPS Placement 4.3.7. Manual Placement Position the mouse pointer over the node symbol. The pointer will change to a four-headed arrow. Left click and drag the node to the position on the map where the node should be displayed. Note: You can drag a node symbol to anywhere on the map. Normally, you would place the symbol where the node is actually located, but there is nothing to stop you just randomly placing the symbol in Portsmouth when the physical NETNode is in Southampton for example.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-42 DS000034 Unclassified 4.3.8. GPS Placement If a NETNode has a GPS unit connected it can report its position which can then be displayed on the map. Section 6.3 Configuring NETNode for GPS details how to connect GPS to a Mesh. 1. Ensure you are connected to a NETNode with GPS attached. 2. Ensure the Use GPS check box is checked. 3. The symbol for that node will now snap to the correct location on the map where the actual NETNode is currently located. If it moves, it will move on the map, showing heading speed and height. 4.3.9. Upload Map Data Each of the four map radio buttons can contain a different map. These maps need to be uploaded before you can use them. 4.3.9.1. Upload Map Image File To upload a map you‟ll need an internal drive which has been formatted. (Information Tab). You‟ll also need an image file containing the map for the area you are interested in. The system supports four file types for maps:  .JPG  .PNG  .GIF  .BMP We recommend using JPEG or PNG as they are good quality but small files. Bitmaps on the other hand are excellent quality but very large. There is a limited amount of memory available in each NETNode for maps. 1. Click the Upload… button 2. The Upload Map Data dialog opens 3. Click the Browse button and navigate to your image file. 4. Click the Upload File button to place the image in the NETNode‟s flash memory.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-43 DS000034 Unclassified 4.3.9.2. Set Coordinates When you have loaded your map, you‟ll need to find out the coordinates of three of the corners of the map image to enable the GPS feature to work. You‟ll need to know the Top Left, Top Right and Bottom Left coordinates of your image. These coordinates must be in decimal form and accurate to six places. (You may be more familiar with Latitude and Longitude being expressed in hours minutes and seconds). You can get the coordinates from your map data source for example. 1. Click the Set Coordinates button. 2. The Coordinates dialog box opens. 3. Type in the coordinates of each of the corners of the image. 4. Click OK. 4.3.9.3. Reset Locations… When you have loaded a new map or you have been moving nodes on an existing map you may need to reset their locations. This can be useful if you lose nodes off the edge of the map. You can force the system to reset the locations of all the nodes or any combination of them. 1. Click the Reset Locations… button 2. The Reset Locations dialog opens
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-44 DS000034 Unclassified 3. Click the All button or check the nodes you want to reset 4. Click OK 5. The system resets the locations and switches off the GPS tracking function.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-45 DS000034 Unclassified 4.4. Global Settings Tab 4.4.1. Unit Name The NETNodes are uniquely identified by the Node ID parameter which is a number between 0 and 11. This is not a very useful name for normal operations so this text box allows you to enter a better description for the node which will appear on network diagrams and maps within the software. 1. Type in a meaningful name for the NETNode. 2. This name will be used in all maps and network diagrams for this node Note: You can use up to 12 alphanumeric characters for the Unit name 4.4.2. Control/Data Port On a Phase 1 NETNode unit the Control/Data port uses the CA0288-5 cable which has an Amphenol 19-way plug (m) on one end and two D-Type 9-way plugs (f) on the other end labelled RS232 and RS485. On a Phase 2 Plain box NETNode the Control/Data port is labelled AUX and uses the CA0474 cable which has two D-Type 9-way plugs (f) on the other end labelled RS232 and RS485. On a Phase 2 Robust unit the Control/Data port uses CA0406 which has an Amphenol plug (m) on one end and two D-Type 9-way plugs (f) on the other end labelled RS232 and RS485. Normally we use RS232 for Control.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-46 DS000034 Unclassified There may be times when you want to change this and so this combo box enables you select other setting for the plugs on this cable. You can select from the Control/Data Port box: On both Phase1 and Phase2 Mesh nodes up to and including Software release V1.4 there is only one data channel and one serial control channel. If the Data channel is set to the RS232 port then the control channel is forced to the RS485 port and vice versa. Setting Means… RS232/RS485 Control is RS232 plug, Data Port is RS485 plug (normal) RS485/RS232 Control is RS485 plug, Data Port is RS232 plug RS232/RS232 Special mode, only used for engineering. 4.4.2.1. Control/Data Port - Software Version 2.1 Software version 2.1 allows for the use of two separate data channels RS232 and RS485. The RS485 is now a dedicated port on the unit. The RS485 can no longer be configured to be a Unit Control channel – it is now a dedicated data channel. The RS232 data channel shares with the control port. So the RS232 serial port can be set to be a second data channel. A second RS232 port is available on units without the AVI option fitted and this second channel can also be configured to be a data channel or a control port. If the AVI option is fitted then the second serial port is used to control the AVI encoder. Setting Means… RS232 1/RS232 2 Data is on RS232 plug RS232 2/RS232 1 Control is on RS232 plug Caution: D830 – Do not set the control data port to „Data is on RS232 plug‟ if you are controlling the unit via this port, and the unit cannot be controlled via IP. 4.4.3. Auxiliary Address Normally, the NETNode will be operating with IP devices like cameras microphones or GPS units and the Auxiliary address is left as 0.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-47 DS000034 Unclassified Some NETNodes (the AVI variant) are able to use composite cameras. To do this they have an extra Video / Audio and data encoder board fitted inside the unit. To ensure the NETNode recognises and uses the internal encoder card we have to set the auxiliary address to 1. Now your composite camera can be used with the system. Caution: If you ever reset defaults on the NETNode it will reset the Auxiliary Address to zero. You must reset this to 1 for your composite camera to work. 4.4.4. Relay Only Normally each NETNode will have at least one source of sensor data attached to it, for example, a camera or a microphone. However, occasionally the NETNode only needs to act as a relay, for example, when you are setting up a chain network for range extension or working with a helicopter relay. In this case you would check the Relay Only check box. Note: When the Relay Only check box is checked it simply disables any Ethernet connectivity to the NETNode. 4.4.5. Speed Units If you have a GPS connected to a NETNode it can supply speed data. You can choose the units you want to use for speed in this combo box. The possible choices are:  Knots  MPH  KPH 4.4.6. Streaming Protocol This allows either multicast (raw UDP) or RTSP streaming (RTP multicast/unicast) of the internal video encoder. See Section 5 on Streaming as this explains the intricacies of Video streaming over IP in more detail. 4.4.7. DHCP Enable In some situations having DCHP enabled may be appropriate for advanced users of the system but in most cases it‟s better if each NETNode has its own fixed address. Fixed IP address allocation is better when a system is in a dynamically changing environment as operation is such an environment means that connection to the DHCP server can not always be guaranteed. If checked, then the NETNode will try to acquire its IP address from a DHCP server on the network – this DHCP server can be located through another NETNode over the radio interface. 4.4.8. IP Address If the NETNode is not automatically acquiring its IP address via a DHCP server then a fixed IP address needs to be assigned to the unit. This address is typically obtained from a
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-48 DS000034 Unclassified network administrator to avoid a clash of IP addresses on any network. The unit is expecting an IPv4 address. Enter an IP address for this NETNode in the IP address text box. It can be any class of network you choose. 4.4.9. Network Mask The network mask allows a network administrator to break a network into smaller more efficient subnets to prevent excessive numbers of IP packets being routed through the network. This is normally defined by the network administrator Enter a subnet mask in the Network mask text box. 4.4.10. Gateway A default gateway is used by a host when an IP packet's destination address belongs to someplace outside the local subnet. The default gateway address is usually an interface belonging to the LAN‟s border router. We recommend you leave the gateway at 0.0.0.0 4.4.11. 12 Node System This box should be ticked for support for up to 12 nodes. It should be unticked if backwards compatibily with V2.x (8 Node) software. 4.4.12. Update All Nodes When you make changes to any setting they are normally applied only to the NETNode you are currently attached to. Sometimes it‟s really convenient to update all the NETNodes in the mesh, for example when you want to change the frequency of all units at the same time. Check the Update All Nodes checkbox to enable these global updates on all nodes. Not all parameters are updated globally on the Mesh:- just Frequency, Bandwidth, Encryption, RTSP streaming, 12 Node system mode parameters. CAUTION: All nodes in a Mesh must be in range and connected for a „Update all Nodes‟ command to work across the whole Mesh. If the command is issued and while a node has dropped out of the Mesh as it is out of range then it will not receive the command and may not reconnect to the Mesh when it returns into coverage. If this happens changing the parameters back to the original values may restore operation. Note: All nodes on the Mesh must have the same mode set. To change all the nodes from an 8 Node (compatible) to the new 12 Node system use the update all nodes tickbox.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-49 DS000034 Unclassified 4.4.13. Setting the clock (Phase 2 units only) The real time clock is used to timestamp the recordings on the external memory card. The clock may either be set manually or synchronised to a GPS unit connected to any node of the system. The clock internally runs in UTC time and the user may set the time-zone offset and daylight saving time. Note the units do not automatically adjust for daylight savings. 4.4.14. Format File System… There are two flash drives built into each NETNode.  Internal Flash  External Memory Card Note: The External memory card is only available on Phase 2 units Note: The External memory card slot ONLY support basic 2GB or 4GB SD cards Flash Use Internal Flash Holds the maps and coordinate files. External Memory Card Use for video recording on Phase 2 units
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-50 DS000034 Unclassified Here‟s how you format these drives: 1. Click the Format File System… button The Format Flash File system dialog opens 2. Click Format Internal Flash button 3. Your internal Flash drive will be formatted. Caution: When you press the Format Internal Flash button the system does not ask you to confirm your actions – it just formats the drive. Be very sure you want to do this. Note: If you want to format the External Memory Card, click the Format External Memory Card button at step 2 above. 4.4.15. Restore Defaults… To restore a default condition to the whole unit: 1.

NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-52 DS000034 Unclassified 4.5. Configuration Tab – Transmitter Pane Note that there are eight configuration tabs enabling you to have eight completely different setups stored in the NETNode. We are going to look at just tab one – they are all identical. In the example above, the green square on tab 1 shows we are working on configuration number one. The transmitter pane enables you to change the frequency of a NETNode, set the transmission bandwidth and adjust the output power level of the NETNode. 4.5.1. Preview and Active Configuration A configuration can be Active or Previewed. This can be determined by looking at the Configuration numbers. The active configuration is darker blue than the inactive configurations. To preview a configuration the user can click the configuration number and the previewed configuration is then highlighted in Green. A user is able to preview configurations without activating the configuration. To activate a previewed configuration the user needs to click the „Apply‟ button.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-53 DS000034 Unclassified Note: All configuration parameter changes need to be confirmed by clicking the „Apply‟ button before the changes are activated 4.5.2. Enable Transmitter Check Box This simply turns on the transmitter when checked. All NETNodes in a mesh must have their transmitters enabled. 4.5.3. Frequency Input the frequency in MHz that you want to use for this NETNode. 4.5.4. Channel Bandwidth You can configure the channel bandwidth with this combo box. There are three choices: 2.5 MHz 3.0 MHz 3.5 MHz 5.0 MHz (V2.1 software and unit types 68 upwards only) See Section 4.12 Information Tab to discover the Board type and the Software version. 4.5.5. Output Level High and Output Level Low These two text boxes allow you to set the level of attenuation in dB that will be applied to the low and high output levels. This could be useful if your transmitter is swamping another unit in close proximity. You can set anything between 0 to 30 dB. 4.5.6. Output Level Select You can choose high or low output level to suit the RF environment you are working in. When you select high or low here it applies any attenuation you have set in the output level setting discussed above.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-54 DS000034 Unclassified 4.6. Configuration Tab – Mesh Pane 4.6.1. Mesh ID The Mesh ID tells the unit which group it belongs to. All NETNodes on Mesh ID 122 for example will communicate with each other. This means you could set up another mesh with Mesh ID 125 for example on the same frequency which would run independently of Mesh 122 (though you would have to be careful about interference and run the units in separate areas). You can choose any numbers from 001 to 255 for your Mesh ID. Different Mesh systems should not be allowed to co-exist on the same frequency. 4.6.2. Node ID The Node ID gives the unit a unique ID within the mesh. You can have up to twelve NETNodes in a mesh and they each must carry a unique Node ID. You can choose any numbers from 0 to 11 for your Node ID. A node may choose to automatically reassign its‟ node ID on power if it conflicts with an existing node on the network. 4.6.3. IP Forward If this NETNode is connected to an IP source then checking the IP Forward check box will ensure this data is passed around the mesh for access on other units. A node will forward IP data when it finds that the data cannot get from the source node to the destination node in a single hop. Leave this box checked for normal operation. 4.7. Configuration Tab – Streamer Pane When you have got the asset to the NETNode, you may want to stream that information down a fixed IP link. The streamer pane enables you to configure this facility easily for Multicast IP streaming. Streaming is the transmission of digital audio or video or the listening and viewing of such data without first storing it. In Cobham systems we have the ability to carry streams using Multicast, Unicast and RTSP protocols. The protocol selection is performed within the Global settings tab (see Section 4.4.6 Streaming Protocol).The Streamer pane within the configuration tab is purely associated with Multicast streams. These streams can come from external or internal sources. This is controlled by the Source Mask. To ensure we don‟t overload the bandwidth we want to be able to choose which nodes get to receive the stream. This is controlled by the Destination Mask.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-55 DS000034 Unclassified 4.7.1. Source Mask The Source Mask enables the streaming of Video that originates from a network connected to either one of the two NETNode Ethernet ports or from the internal encoder (if it is fitted). Here‟s how to configure it: 1. Click the Source Mask Set… button 2. The Streamer Source Mask dialog will open 3. Place a check mark in the check box that is the source to stream down the link. 4. Click OK In our example we are planning to stream from the composite camera connected to the internal AVI encoder. Here are all the possible connections involved: Source Front Panel Label Connector (Robust Units) Connector (Plain Box) Eth0 IP Amphenol RJ45 (f) Eth1 CTRL/DATA Amphenol RJ45 (f) Encoder Internal (if fitted) Internal (if fitted) Internal (if fitted) Eth0 and Eth1 will be from a network connected to the NETNode. Encoder will ONLY be valid if the NETNode has the AVI-UP option (internal AV Encoder) fitted.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-56 DS000034 Unclassified 4.7.2. Destination Mask You can choose which NETNodes will receive the stream. Your NETNode could have up to eight NETNodes attached to it via the mesh. Multicast streaming to all nodes is an inefficient use of mesh capacity and so you need to be able to restrict the multicast to specific nodes. 1. Click the Destination Mask Set… button 2. The Streamer Destination Mask dialog will open 3. Check the node check boxes for the NETNodes that you want to receive the stream. 4. Click OK When RTSP streaming is enabled this box will be greyed out and the destination mask selected automatically as defined by the RTSP connection. Note: The Eth0 and Eth1 are ticked by default. These ports will be used as the exit point from the mesh at the node(s) you have specified. 4.7.3. Multicast Address This text box enables you to change the multicast address used by the unit. The default value is 239.16.33.254.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-57 DS000034 Unclassified 4.7.4. SAP Address This text box enables you to change the value of SAP/ SDP multicast address used by the unit. The default value is 224.2.127.254 and the port used is 9875. These are standard multicast values for such parameters, and it is recommended they are not changed unless specifically required due to routing restrictions. 4.7.5. Port Protocols like TCP or UDP use port numbers in the header to direct traffic around the network. Low port numbers are used by computer systems for predefined tasks. For example SMPT (for your email service) uses port 25. A good rule is to use numbers above 10,000 to avoid conflict with existing services. When you set up a port number on several computers on a network they will all listen for packets directed to that port. The default value is random. 4.7.6. Service Name This text box lets you name the multicast stream as delivered in the SAP/SDP packets from the unit. Default is MPEG Stream. 4.8. Configuration Tabs – Data RS232/RS485 Pane The NETNode can send and receive data through either of its RS232 serial port, and its RS485 serial port (V2.1 onwards). Configuration of the RS232 port is found under the Global Settings tab (see Section 4.4.2 Control/Data Port). It is possible to configure the system to send data from one NETNode serial port to another NETNode serial port or from a NETNode to a PC connected on the same IP network. 4.8.1. Data Mode The Data Port can be configured in three ways:  Off  UDP  TCP server  TCP client (V2.1 onwards) 4.8.1.1. Off Data transfer is switched off.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 2-58 DS000034 Unclassified 4.8.1.2. UDP UDP (User Datagram Protocol) is used to move data about the network. The packets are sent out and the system does not expect a reply. There is no way that the sending device can tell if the data arrived at the destination. 4.8.1.3. TCP Server TCP (Transmission Control Protocol) is used to move data about the network. The packets are sent out and the system will expect a reply. Each message is acknowledged by the destination device. 4.8.1.4. TCP Client This mode allows the NETNode data port to connect to another NETNode in server mode using a robust TCP link. 4.8.2. Baud Rate This is where you set the speed at which data will be transferred across the network. Speeds available are: None, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200. Note: The data is assumed to be 8 bits. 4.8.3. Parity A parity bit is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code. There are two variants of parity bits: even parity bit and odd parity bit. This combo box allows you to set: None, Even and Odd. 4.8.4. IP Port and IP Address These set an IP address and Port to and from which the data will transferred. The user can connect to the data port via telnet by setting the mode to TCP server and the port number to 23. The user can connect two data ports on different units together via setting UDP mode and using the matching port numbers. To send data between two nodes the data IP address of each node should point at the other and the ports must match. To send data between two nodes one node should be set to server, one to client, the IP address of each node should point at the other and the ports must match.

IP Data Scrambling It can be important to scramble sensitive data before they are passed across radio networks. The system offers AES128 and AES 256 and this encrypts all user data exchanged over the network. The AES128+ and AES256+ settings ensure that the NETNode will only receive encrypted data. Any data sent in the clear by any nodes will not be accepted by a NETNode if the AES+ is set on the unit. This combo box enables you to select the scrambling scheme you want to use. You can select: AES128, AES128+, AES256 and AES256+. 4.8.7. Scrambling Key When you choose to use a scrambling scheme you need to specify a key that it will use. Here‟s how: 1.

Configuration Tab – Record Pane The NetNode unit (Phase 2 only) allows recording of the video from the AVI unit unto a SD card. Files are recorded in 30 second lengths, referred to as a „chunk‟, and stored in a compressed transport stream format. They can be subsequently downloaded either through the WEB browser from the file system tab, or alternatively the card may be inserted into an external computer. Files are stored in FAT16 format and so can easily be read. The date and time is always stored in UTC format regardless of the time-zone setting. The card should only be removed when the SD card LED is green and not red. This always occurs at the end of the 30s transfer when record is enabled. Failure to do this may result in a damaged file system on the card. The unit currently supports micro SD cards only. 4.9.1. File length This is the maximum number of files stored on the card the oldest will be removed first. This should be set so that the number of files does not exceed the capacity of the SD card. 4.9.2. Record Tick box to start recording. Untick the box to stop. 4.10. Configuration Tab – Audio Pane NETNode phase 2 contains an audio talkback feature which allows operatives to communicate over the mesh using their own headset. The system allows each user to talk to all other users. To use this feature, a headset with microphone needs to be connected to the unit. The NETNode unit provides a small amount of power to the microphone capsule. The pin-outs for the talkback audio connectors can be referenced in Section 12.6 T/B - 6-pin 0B LEMO socket (G-key) for the Plain box unit and Section 13.3 Misc Connector Amphenol 38999 Series 3 13-35 22 way chassis socket for the Robust variant.

NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 5-66 DS000034 Unclassified 5. Streaming over IP 5.1. General Info This section is relevant only to customers that have the NETNode-AVI-UP option fitted into their NETNode unit. 5.2. Multicast Streaming The NetNode supports both raw multicast streaming and RTSP/RTP streaming. 5.2.1. Streamer Operation For multicast streaming the transport stream video data is transmitted over the Ethernet network by means of “multicasting” i.e. continuous real-time streaming of packets accessible to any PC connected to the network. It is therefore possible for more than once connected PC to view the streamed data simultaneously. Two types of multicast IP packets are streamed.  Packets carrying video, audio and data as received by the unit;  Packets known as Session Announcement Protocol and Sessions Description Protocol data (SAP and SDP), which contain information regarding the nature and location of the stream itself. 5.2.2. Configuration Tab – Streamer Pane (Multicast Mode) When you have got a Video or Audio product into the NETNode, you may want to stream that information down a fixed IP link. The streamer pane enables you to configure this facility easily. Streaming is the transmission of digital audio or video or the listening and viewing of such data without first storing it. In Cobham systems we have the ability to carry streams using multicast protocols and these streams can come from external or internal sources. This is controlled by the Source Mask. To ensure we don‟t overload the bandwidth we want to be able to choose which nodes get to receive the stream. This is controlled by the Destination Mask. 5.2.2.1. Service Name Textual information naming the multicast stream as delivered in the SAP/SDP packets from the unit. Default is “Mesh Streaming” 5.2.2.2. Source Mask The Source Mask enables the streaming of Video that originates from a network connected to either one of the two NETNode Ethernet ports or from the internal encoder (if it is fitted).
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 5-67 DS000034 Unclassified This pop-up box enables the streaming of Video from either one of the two external Ethernet ports or from the internal encoder (if it is fitted). Enabling one of the two Ethernet ports allows a stream on an external network connected to the NETNode Ethernet ports to pass into the Mesh network. Enabling the Encoder tick box allows the internal MPEG encoder (if fitted in the NETNode as option NETNode-AVI-UP) to stream over the Mesh network. Here‟s how to configure it: 1. Click the Source Mask Set… button 2. The Streamer Source Mask dialog will open 3. Place a check mark in the check box that is the source to stream down the link. 4. Click OK In our example we are planning to stream from the composite camera connected to the encoder. Here are all the possible connections involved: Source Front Panel Label Connector (Robust Units) Connector (Plain Box) Eth0 IP Amphenol RJ45 (f) Eth1 CTRL/DATA Amphenol RJ45 (f) Encoder Internal (if fitted) Internal (if fitted) Internal (if fitted) Eth0 and Eth1 will be from a network connected to the NETNode. Encoder is ONLY valid IF the NETNode has the AVI-UP Option (internal AV Encoder) fitted. 5.2.2.3. Destination Mask You can choose which NETNodes will receive the stream. Your NETNode could have up to eight NETNodes attached to it via the mesh. Streaming to all nodes is an inefficient use of mesh capacity and so you need to be able to restrict the multicast to specific nodes. This pop up box allows the user to specify precisely which nodes need to receive the stream. Streaming to all nodes may be an inefficient use of MESH IP capacity and so the user may wish to restrict the multicast to specific nodes. Note: Please note after hitting the OK box on the source or destination mask, the main Apply Bottom must be pressed to action the command.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 5-68 DS000034 Unclassified 1. Click the Destination Mask Set… button 2. The Streamer Destination Mask dialog will open 3. Check the node check boxes for the NETNodes that you want to receive the stream. 4. Click OK Note: The Eth0 and Eth1 are ticked by default. These ports will be used as the exit point from the mesh at the node(s) you have specified. 5.2.2.4. Multicast Address This text box enables you to change the multicast address used by the unit. The default value is 239.16.33.254. 5.2.2.5. SAP Address This text box enables you to change the value of SAP/ SDP multicast address used by the unit. The default value is 224.2.127.254 and the port used is 9875. These are standard multicast values for such parameters, and it is recommended they are not changed unless specifically required due to routing restrictions. 5.2.2.6. Port A good rule is to use numbers above 10,000 to avoid conflict with existing services. When you set up a port number on several computers on a network they will all listen for packets directed to that port.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 5-69 DS000034 Unclassified 5.2.2.7. Service Name This text box lets you name the multicast stream as delivered in the SAP/SDP packets from the unit. Default is MPEG Stream. 5.3. RTSP Streaming Real Time Streaming Protocol allows automatic control of the routing through the Mesh system. To use this feature the streaming protocol box should be set to the same RSTP multicast or unicast modes for all nodes in the system (this will happen if the „update all nodes‟ checkbox is ticked). The streaming protocol is selected on the Global Settings tab – see Section 4.4.6 Streaming Protocol for details. To access a stream on an AVI unit the URL is as follows: rtsp://<ip_address_of_AVI_unit>/stream.sdp This will automatically set the internal destination masks of the AVI node and the endpoint node (the node where the data emerges from the Ethernet) to the correct values. The destination values displayed in the destination mask on the Configuration Tab no longer have any effect in this mode of operation. If necessary the endpoint node will convert the multicast RTP packets to unicast (and remap the port numbers) if the Software player does not support multicast streaming. Unicast may also be forced by setting the mode to RTSP unicast. The Mesh always uses multicast packets internally as this is more bandwidth efficient when reaching multiple destinations. Note the player must be able to support transport stream packets (MP2T – suitable players include VLC media player). Ports on different AVI NETNodes should be set to different unique values (use even addresses for RTSP/RTP). The source mask, internal multicast address, service name and port number are still used in this mode. 5.4. Stream Recording and playback (v2.1) The AVI enabled NETNode allows recoding of video streams onto a SD card (phase 2) onwards. To use this facility first insert and 2GB SD card into the slot. This will cause the green LED on the SD card slot to come on. The card should only be removed when the LED is green to prevent corruption of the data on the card. SD card slot behind cap

If not, the flash can be formatted using global setting->format file system box. 5.4.2. Recording The set the recording mode make sure the AVI unit‟s video encoder is set up correctly and the video feed connected from the camera. On the configuration tab->recoding pane enable the record tick box. The data is recorded onto the SD card in 30s chunks. Therefore the size of each chunk is the encoded bit-rate (in bits/s) * 30 / 8. Set the maximum number of chunks to be less than the capacity of the card over the chuck size, to prevent the data from exceeding SD card capacity. To check recording is taking place move to information->file system->flash card->stream directory. Each file is one chuck representing 30s of data. Once the number of chucks is reached, the oldest file is deleted and recording continues providing the SD capacity is not exceeded.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 5-71 DS000034 Unclassified For example to set a continuous recording of the last 5 minutes of encoded video the user would set the number of chunks to 10 and this would continuously record and overwrite the last 10 minutes of video. With a 1Mbps video stream and a 2GB SD card a user should be able to record just over 4 hours of video data. 1Mbitps is equivalent to 125kBytes/second of data. A 2GByte SD card can store 16,000 seconds of video before it hits capacity or 533 30 second chunks. To leave a safe margin a 500 chunk limit should be used giving just over 4 hours of recording if recording a 1Mbps video stream. 5.4.3. Playing back the recorded data The record data may be viewed directly with a player such as VLC media player using the following RTSP url: rtsp://<ip_address_of_AVI_unit>/record.sdp In this mode of operation the slider bar on VLC may be moved to navigate to different parts of the recording. Note play will always commence on the next 30 second chunk. The NTP timestamps in the data contain the time the recording was transferred to SD card. 5.4.4. Transferring the files Individual recorded files may be transferred to the PC using the Web interface to download the files. To perform this operation, simply right click on the file. The SD card may also be removed and inserted into a card slot on the PC to read the files. The SD card format is FAT16 with the date stored in UTC format.

General Information This section is relevant only to customers that want to use GPS with the NETNode unit. This chapter will explain how to enable GPS position data on your system. It can be very useful to show the position of all the nodes on a digital mapping screen. Sometimes these nodes will be in a fixed position on top of buildings for example. In other situations the nodes may be constantly moving in a vehicle or aircraft for example. You can enable GPS position data using a suitable GPS receiver on as many nodes within the mesh as you wish. For GPS position data to be used to move nodes on the map you must place a checkmark in the Use GPS checkbox. Now the GPS position data will be automatically used to position the nodes on the digital mapping you have loaded into the mesh system. The mesh system uses the NMEA 0183 GPS protocol to passing data. 6.2. Connecting the GPS unit to the NETNode The connections you use for the GPS will depend on the GPS receiver being used and the type of NETNode you have. We‟ll take the example of connecting a Phase 2 Plain Box NETNode and a Garmin 17X GPS receiver. Take the 15-way High Density D-Type plug (Male) and connect it to the 15-way High Density D-Type jack (female) labelled AUX on the Phase 2 Plain Box NETNode.

VLAN Support (v2.4) A virtual LAN, commonly known as a VLAN, allows a number of networks to share the same physical resource such as the mesh network or more typically shared IP bandwidth over a satellite link. The use of VLAN makes it possible to have completely separate networks running over a common NetNode mesh system without sharing data between the networks. VLANs are created to provide the segmentation services traditionally provided by routers in LAN configurations. VLANs address issues such as scalability, security, and network management. Routers in VLAN topologies provide broadcast filtering, security, address summarization, and traffic flow management. By definition, switches may not bridge IP traffic between VLANs as it would violate the integrity of the VLAN broadcast domain. 7.1. Configuring VLAN By default the standard mesh network does not allow passage of VLAN packets. In order to allow VLAN packets through the system each NetNode must be programmed with the VLAN tag, subnet mask and a valid IP address for each VLAN. The setting of the IP address and subnet mask allows additional filtering of the IP packets as they enter the NetNode. It also allows the generation of ARP and ICMP reply packets which aids internal routing and testing of the VLAN network. The NetNode mesh network supports up to 8 separate VLANS. Each VLAN is maintained by a separate routing table within each NetNode. In the example above the NetNode is set up to support a VOIP (Voice Over IP) system operating using a VLAN through the mesh system. If the user does not want the node to respond to its own VLAN IP address the IP Address should be set to 10.240.1.255. The combination of IP Address „Or-ed‟ with the Sub net mask must be 255.255.255.255 to ensure that the Netnode itself will not respond to Ping requests on the network 7.2. Setting VLAN tagging and stripping on External ports The netnode allows VLAN tagging and stripping on the two external Ethernet ports. In the example below Port 1 is acting as a normal Ethernet port allowing a user to web browse as
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 7-79 DS000034 Unclassified normal into the radio and indeed send data over the radio network on the same IP address range as the radio IP addresses. Port 2 is configured to support a VLAN with a Tag of 1531. 7.2.1. VLAN tagging VLAN tagging adds the VLAN tag as the packet enters Netnode the port and removes it again when a VLAN packet of the correct tag exits. Only VLAN packets with the correct tag will exit the port. This is selected by GlobalSettings->Ethx Mode->LAN<->VLAN. The tag number and priority must also be specified. 7.2.1.1. Use of VLAN tagging Suppose the system administrator wishes a camera to be connected to each NetNode, but each on a separate network so that individual users cannot snoop onto other cameras, or change the configuration of the Mesh system. Connecting the camera to each Netnode and setting the Ethernet port using different VLAN tags for each NetNode would allow this. The endpoint node could pass the VLAN tags unaltered by setting GlobalSettings->Ethx Mode->Normal, and programming all 8 VLAN addresses and tags in this node. The endpoint node could then be connected to an external intelligent router which puts out the separate LAN networks out on separate ports. In this example the endpoint would typically be at the HQ building (the command and control centre.) 7.2.2. VLAN stripping VLAN striping removes the VLAN tag as the packet enters the port and adds it again when the packet exits. This is selected by GlobalSettings->Ethx Mode->VLAN<->LAN. The tag number and priority must also be specified. Note stripping will block non VLAN traffic on that port. Priority is required but currently is not implemented in the mesh system. 7.2.2.1. Use of VLAN stripping VLAN strpping allows a NetNode to pass its data over a IP backbone without interference to other traffic on the network. It also has the potential to allow multiple NetNodes on the same mesh network to connect to the same IP infrastructure. Note: Changing the Mode of the Ethernet port which you are currently using to control a Netnode will cause loss of control of the unit. The user may only be able to regain control using the other Ethernet port or the RS232 interface.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 7-80 DS000034 Unclassified 7.2.3. Mode Off This disables the external port and is useful for security. !Warning: Changing the Mode of an Ethernet port to VLAN can cause temporary collapse to the IP network the NetNode is connected to, if done incorrectly. A good understanding of the network topology is required before implementing VLAN on a mesh system.
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 8-81 DS000034 Unclassified 8. Interlink Mode Normally IP networks do not allow multiple routes from an IP source to an IP destination address. This precludes multiple nodes to be connected to the same IP backbone network. For example in a city it is often advantageous to have multiple high points on the same Mesh all connected to the same IP backbone. In this example connection of two NetNodes onto the same IP backbone would cause a loop to be created in the network. In practice each NetNode identifies this network loop occurrence (same MAC address appearing on multiple ports) and blacklists the entry for 30 seconds, to prevent this happening. However, it can be extremely useful to be able to connect multiple NetNodes to the same backbone. For example, a city Mesh system may have two nodes on two different buildings. In this example it may be that a mobile node is only served by the one of the two nodes (for example Mesh #1 in the diagram below), and if this not the node connected to the backbone then IP forwarding over the radio link would have to take place. This reduces the overall network capacity; as the hop means information has to be sent twice over the radio network. 8.1. Operation Interlink mode replaces the radio links between the Mesh nodes on the backbone with an IP tunnelling protocol over the IP backbone. To make this IP tunnelling possible one of the NetNodes acts as a master allowing both tunnelling data and the main IP data through the Ethernet interfaces while the other nodes act only as slaves just allowing IP tunnelling data to and from that node. Mesh #1 Mesh #2 Camera IP Backbone
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 8-82 DS000034 Unclassified To isolate the IP layers each NetNode contains a second IP address (and MAC address) which is used for the tunnelling. This IP address only supports ARP, ICMP (ping) and the UDP tunnelling packets. When this Interlink mode is activated, each node also sends out a broadcast packet on the second IP interface which advertises it‟s presence on the IP backbone. This allows each node to know what other nodes are connected to the backbone, and therefore whether the interlink data can be sent over the IP network. The nodes also check that there is one and only one master on the network and correct this if necessary. This is useful if, for example, the master is lost from the network. 8.2. Configuring Interlink Mode If there are multiple mesh networks on different frequencies anywhere on the same network they must have different Mesh ID‟s before starting. This can be checked with Nodefinder. To enable the interlink mode first make sure only one NetNode is connected to the IP backbone, and all other nodes to be connected are currently accessable on the Mesh Network. Set the tunnelling IP address and the Tunnel Mode to „Master‟. This should leave the unit connected to the network. You should now be able to ping the tunnel IP Address as well as the unit‟s main IP address. Without changing the Mesh topology, connect to each node in turn on the IP backbone. Set the tunnel IP address and the tunnel Mode to „Slave‟. You will only be able to ping the tunnel IP address when the unit is connected via the backbone. Leave the Tunnel Mode of the nodes not connected to the backbone to Off. Main IP address 10.184.51.9 Tunnel IP address 10.184.51.219 Main IP address 10.184.51.15 Tunnel IP address 10.184.51.215 IP Backbone IP address 10.184.51.17 Tunnel Data Master Slave
NETNode Phase 1 and 2 Units NETNode User Manual NETNode-V2.3 8-83 DS000034 Unclassified When all nodes have been configured they can all be connected to the common backbone. You may need to wait unit 1min before the Mesh is accessible. Note: The Interlink NetNodes must always be linked via the radio interface, as well as the IP backbone to operate correctly. This ensures the system remains as a single Mesh Network. Note: Do not connect a unit on the same Radio Network to the same IP backbone with its Tunnel Mode set to Off. This will result in loss of functionality. First set the mode to master or slave and then connect. Note: All separate Mesh networks connected to the IP network (no matter where) must have different Mesh ID‟s. Failure to do this will result in loss of functionality.
