The transceiver is ide-ally suited for demanding applications in fixed environments, where reliability and range are paramount.The transceivers are commonly used to convey text documents, graphics, e-mail, video, Voice over IP (VoIP), and a variety of other application data between fixed-point and WAN/LAN-based entities.Based on multi-carrier Orthogonal Frequency Division Multiplexing (OFDM), the transceiver features high speed/low latency, basic Quality of Service (QoS) for prioritizing traffic, Ethernet and serial encapsula-tion, and network roaming. It also provides enhanced security features including AES encryption and IEEE 802.1x Device Authentication, making the Mercury system the best combination of security, range, and speed of any industrial wireless solution on the market today.Invisible place holderFigure 1-1. The GE MDS Mercury SeriesTM Transceiver(Remote unit shown, AP is similar in appearance)Rugged Packaging The transceivers are housed in a compact and rugged die cast-aluminum case that need only be protected from direct exposure to the weather. This one enclosure contains all necessary components for radio opera-tion and data communications.
05-4446A01, Rev. C Mercury Reference Manual 5Simple Installation Mercury Transceivers are designed for rapid and trouble-free installa-tion. For basic services, you simply connect the antennas (3650 MHz and GPS, as required), connect your data equipment, apply primary power, and set some operating parameters. No license is required for operation in the USA, Canada, and many other countries. Check requirements for your region before placing the equipment into service.Most installations employ an omni-directional antenna at the Access Point (AP) location and remote stations. Fixed Remote stations often employ a directional antenna aimed at the AP. Regardless of the type used, antennas are a vital part of the system and must be chosen and installed correctly. Refer to INSTALLATION PLANNING on Page 149 for guidance on choosing suitable antennas and installation sites.Secure Operation Data network security is a vital issue in todays wireless world. Mercury transceivers provide multiple tools to help you build a network that min-imizes the risk of eavesdropping and unauthorized access. Some are inherent in the radios operation, such as the use of 3650 MHz spread-spectrum transmissions; others include data encryption, enabling/disabling channels, and password protection.Security is not a one-step process that can simply be turned on and for-gotten. It must be practiced and enforced at multiple levels, 24 hours-a-day and 7 days-a-week. See GE MDS CYBER SECURITY SUITE on Page 16 for more information about the transceivers secu-rity tools.Robust Radio Operation The transceivers are designed for operation in the license-free 3650 MHz Industrial, Scientific, and Medical (ISM) band. They provide reli-able communications over long distances, even in the presence of weak signals or interference.Range depends on many factors, including terrain, building density, antenna gain, and speed of travel. The unit is designed for successful application in a variety of environments, and offers the best combination of range, speed and robustness available in an industrial wireless package today. By using multiple Access Points, a network can be cre-ated that provides consistent, reliable coverage over a large metropolitan area. See SPECIFICATIONS on Page 162 for more information on transmission range.Flexible Services Users with a mix of equipment having Ethernet and serial data interfaces can use this equipment via a Remote transceiver. The transceiver pro-vides services in data networks that are migrating from legacy serial/EIA-232-based hardware to the faster and more easily interfaced Ethernet protocol.Flexible Management You can locally or remotely configure, commission, troubleshoot, and maintain the transceiver. Four different modes of access are available: local RS-232 console terminal, local or remote IP access (via Telnet or SSH), web browser (HTTP, HTTPS), and SNMP (v1/v2/v3).
6 Mercury Reference Manual 05-4446A01, Rev. CThe text-based interfaces (RS-232 console, Telnet, and SSH) are imple-mented in the form of easy-to-follow menus, and the terminal server provides a wizard to help you configure the units correctly.Transceiver Features The transceivers design makes the installation and configuration easy, while allowing for future changes.¥ Industrial-Grade ProductExtended temperature range for trouble-free operation in extreme environments.¥ Robust Radio CommunicationsDesigned to operate over long distances in dense, high-interference environments.¥ Robust Network SecurityPrevents common attack schemes and hardware from gaining access or control of the network. Common attack events are logged and reported by alarms.•High Speed—1.5 Mbps is over 100-times faster than 9.6 kbps radios.•Plug-and-Play Connectivity—AP or Remote configuration requires minimal setup.•Built-in GPS Receiver—GPS technology is used for timing and location data. The only external equipment needed for this func-tionality is a GPS antenna (several types are available from GE MDS).1.2.1 Model OfferingsThe transceiver comes in two primary models—Access Point and Remote. Unique hardware is used for each model. Of the Remote radios, there are two sub-types available:Standard Remote and Max Remote, both of which support Ethernet and serial services. Table 1-1 summarizes each radio's interface services.Access Point or Remote?—Identification TipThe outward appearance of AP and Remote radios is nearly identical, however, the hardware for each type is different and they are not inter-changeable. An quick way to identify them is to observe the color of the gasket seal in the center of the radio case. APs have a black gasket, while Remote units have a yellow gasket.Table 1-1.

COM1 provides access to the embedded Management System for all units.
05-4446A01, Rev. C Mercury Reference Manual 7In addition to gasket color, a label on the top of each radio identifies it as an AP or Remote unit. If the label shows an —A suffix, it is an AP. If it shows a —R suffix, it is a Remote.1.2.2 GE MDS P23 Protected Network (Redundant) ConfigurationFor mission-critical applications, a Protected Network Station is also offered. This unit incorporates two Access Points, two power supplies, and a switchover logic board that automatically selects between Trans-ceiver A and Transceiver B as the active radio. Figure 1-2 shows the protected chassis. For system-level information on this product, refer to MDS publication 05-4161A01.Invisible place holderFigure 1-2. MDS P23 Protected Network Station(incorporates two transceivers, with automatic switchover)1.2.3 External GPS PPS OptionThe External GPS Precise Positioning Service (PPS) option allows for an external GPS device to provide the PPS input to the Mercury. This is useful in installations where multiple radios require GPS timing. This option prevents each Mercury from requiring its own GPS antenna. Refer to the electrical specifications in the External GPS PPS Option section on Page 164. This option is only available in hardware revision 1.0.2 or later.1.3 APPLICATIONSThe following sections provide illustrations of typical transceiver instal-lations. This is an overview only. A Network Administrator should be involved in all installation planning activities.
8 Mercury Reference Manual 05-4446A01, Rev. C1.3.1 Fixed Data SystemMercury transceivers support high-speed data communications in an industrial environment. In this application, Remote radios roam between different Access Points, providing seamless transitions and continuous coverage throughout a municipal area. 1.3.2 Wireless LANThe wireless LAN is a common application of the transceiver. It consists of a central control station (Access Point) and one or more associated Remote units, as shown in Figure 1-4. A LAN provides communications between a central WAN/LAN and remote Ethernet segments. The oper-ation of the radio system is transparent to the computer equipment con-nected to the transceiver.The Access Point is positioned at a location from which it communi-cates with all Remote units in the system. Commonly, this is a high loca-tion on top of a building or communications tower. Messages are exchanged at the Ethernet level. This includes all types of IP traffic.A Remote transceiver can only communicate over-the-air to an Access Point (AP). Peer-to-peer communications between Remotes can only take place indirectly via the AP. In the same fashion, an AP can only communicate over-the-air to associated Remote units. Exception: Two APs can communicate with each other off-the-air through their Ethernet connectors using a common LAN/WAN.Invisible place holderFigure 1-3. Typical Wireless LAN1.3.3 Point-to-Point LAN ExtensionA point-to-point configuration (Figure 1-5) is a simple arrangement consisting of an Access Point and a Remote unit. This provides a com-munications link for transferring data between two locations.RemoteRemoteAccess PointRemoteRemoteLANLANWAN/LANLANLAN
05-4446A01, Rev. C Mercury Reference Manual 9Invisible place holderFigure 1-4. Typical Point-to-Point Link1.3.4 Serial Radio Network ConnectivityThe transceiver provides a path for serial devices to migrate to IP/Ethernet systems. Many radio networks in operation today still rely on serial networks at data rates of 9600 bps or less. These networks can use the transceiver as a means to continue using the serial service, while allowing the infrastructure to migrate to an IP format.A Remote transceiver with its serial port connected to a GE MDS serial-based radio, such as the MDS x790/x710, MDS TransNET and others, provides a path for bringing the data from the older radio into the IP/Ethernet environment of a Mercury-based system.Invisible place holderFigure 1-5. Backhaul Network1.3.5 Multiple Protocols and/or ServicesPrior to the introduction of Ethernet/IP-based radios, two radios were often used to service two different types of devices (typically connected to different SCADA hosts). A Mercury radio provides this capability using a single remote unit. The units serial port can be connected via IP to different SCADA hosts, transporting different (or the same) proto-cols. Both data streams are completely independent, and the transceiver provides seamless simultaneous operation as shown in Figure 1-7.

10 Mercury Reference Manual 05-4446A01, Rev. CInvisible place holderFigure 1-6. Multiple Protocol NetworkBy using a single radio, the cost of deployment is cut in half. Beyond requiring only one radio instead of two, the biggest cost reduction comes from using half of the required infrastructure at the remote site: one antenna, one feedline, one lightning protector and ancillary hardware. Other cost reductions come from the system as a whole, such as reduced management requirements. And above all, the radio provides the poten-tial for future applications that run over Ethernet and IP, such as video for remote surveillance.1.3.6 Wireless LAN with Mixed ServicesThe transceiver is an excellent solution for a long-range industrial wire-less LAN. It offers several advantages over commercial solutions, pri-marily improved performance over extended distances. The rugged construction of the radio and its extended temperature range make it an ideal solution even in harsh locations. In extreme environments, a simple NEMA enclosure is sufficient to house the unit.The transceiver trades higher speed for longer range. Commercial 802.11a/b/g solutions are designed to provide service to relatively small areas such as offices, warehouses and homes. They provide high data rates but have limited range. The Mercury transmits at a higher power level, uses a different frequency band, has higher sensitivity, and a nar-rower channel to concentrate the radio energy, reaching farther dis-tances. It is designed for industrial operation from the ground up.IP-based devices that may be used with the transceiver include new, powerful Remote Terminal Units (RTUs) and Programmable Logic Controllers (PLCs). These, as well as other devices, may be used in applications ranging from SCADA/telemetry monitoring, web-based NETview SCADA HostTotal FlowAccess PointRemote SerialRemote SerialSCADA HostModbus/IPRemote SerialAccess PointRTUFlow MeterEIA-232EIA-232EIA-232EIA-232EIA-232EIA-232ROUTERHUBSerialDeviceSerialDeviceSerialDeviceSerialDeviceHUBHUBHUBWAN

Extended-Range LAN with Mixed Applications1.3.7 Upgrading Older Wireless Network with Serial InterfacesMillions of wireless data products have been installed in the last two decades for licensed and license-free operation, many of them manufac-tured by GE MDS. There are several ways that these systems can benefit from incorporating Mercury equipment. The chief advantages are inter-face flexibility (serial and Ethernet in one unit), and higher data throughput. By taking advantage of its built-in serial and Ethernet inter-faces, the transceiver is well suited to replace leased lines, dial-up lines, or existing 3650 MHz multiple address data transceivers.Replacing Legacy Wireless ProductsIn most cases, legacy radio transceivers supporting serial-interface equipment can be replaced with Mercury transceivers. Legacy equip-ment can be connected to the transceiver through the COM1 port with a DB-25 to DB-9 cable wired for EIA-232 signaling. The COM1 port acts as a Data Communications Equipment (DCE) port.NOTE: Several previous GE MDS-brand products had non-standardsignal lines on their interface connectors (for example, tocontrol sleep functions and alarm lines). These special func-tions are not provided nor supported by the Mercury trans-ceiver.

12 Mercury Reference Manual 05-4446A01, Rev. C1.4 NETWORK DESIGN CONSIDERATIONS1.4.1 Extending Network Coverage with RepeatersWhat is a Repeater System?A repeater works by re-transmitting data from outlying remote sites to the Access Point, and vice-versa. It introduces some additional end-to-end transmission delay but provides longer-range connectivity.In some geographical areas, obstacles can make communications diffi-cult. These obstacles are commonly large buildings, hills, or dense foliage. These obstacles can often be overcome with a repeater station.Option 1Using two transceivers to form a repeater station(back-to-back repeater)Although the range between fixed transceivers can be up to 40 km (25 miles) over favorable terrain, it is possible to extend the range consider-ably by connecting two units together at one site in a back-to-back fashion, creating repeater as shown in Figure 1-9. Use this arrangement whenever the objective is to utilize the maximum range between sta-tions. In this case, using high-gain Yagi antennas at each location pro-vides more reliable communications than their counterpartsomnidirectional antennas.Invisible place holderFigure 1-8. Typical LAN with a Repeater LinkOverview Two transceivers may be connected back-to-back through the LAN ports to form a repeater station. If the transceivers are connected directly to each other, you must use an Ethernet cross-over cable. This configu-ration is sometimes required in a network that includes a distant Remote that would otherwise be unable to communicate directly with the Access Point station due to distance or terrain.The geographic location of a repeater station is especially important. Choose a site that allows good communication with both the Access Point and the outlying Remote site. This is often on top of a hill, building, or other elevated terrain from which both sites can be seen RemoteRemoteRemoteRemoteAccessPointAccessPointLAN/WANREPEATERCrossover CableLANLANLANEthernetPOINT-TO-POINT LINK

A detailed discussion on the effects of terrain is given in Section 5.1.2, Site Selection (beginning on Page 151).The following paragraphs contain specific requirements for repeater systems.Antennas Two antennas are required at this type of repeater stationone for each radio. You must take measures to minimize the chance of interference between these antennas. One effective technique for limiting interfer-ence is to employ vertical separation. In this arrangement, assuming both antennas are vertically polarized, one antenna is mounted directly over the other, separated by at least 10 feet (3 meters). This takes advan-tage of the minimal radiation exhibited by most antennas directly above and below their driven elements.Another interference reduction technique is to cross-polarize the repeater antennas. If one antenna is mounted for polarization in the ver-tical plane, and the other in the horizontal plane, an additional 20 dB of attenuation is achieved. The corresponding stations should use the same antenna orientation when cross-polarization is used.Network Name The two radios that are wired together at the repeater site must have dif-ferent network names. For information on how to set or view the net-work names, see STEP 3CONNECT PC TO THE TRANSCEIVER on Page 23.TDD Sync Mode To avoid interference between the two APs that form a repeater station, they should be synchronized so that they will transmit at the same time and receive at the same time. This eliminates the possibility of one AP transmitting while another is trying to receive. This can be accomplished by setting the TDD Sync Mode parameter in the Frequency Configuration menu to GPS Required. See Frequency Control Menu on Page 60 for details.Option 2Using the AP as a Store-and-Forward Packet RepeaterYou can extend a wireless network by using the Access Point as a repeater to re-transmit the signals of all stations in the network. (See Figure 1-10 on Page 14.)
14 Mercury Reference Manual 05-4446A01, Rev. CInvisible place holderFigure 1-9. Typical Store-and-Forward Repeater ArrangementAs with the conventional repeater described in Option 1 above, the loca-tion of a store and forward repeater is also important. A site must be chosen that allows good communication with both the Access Point and the outlying Remote site. This can be on the top of a hill, building, or other elevated terrain from which all sites can be seen by the repeater station antenna. A detailed discussion on the effects of terrain is given in Section 5.1.2, Site Selection (beginning on Page 151).1.4.2 Protected Network Operation using Multiple Access PointsAlthough GE MDS transceivers have a very robust design and have undergone intensive testing before being shipped, it is possible for iso-lated failures to occur. In mission-critical applications, down time can be virtually eliminated by using some, or all, of the following configu-rations:In a point-to-multipoint scenario, the Access Point services multiple remotes. A problem in the Access Point will have an effect on all remotes, since none will have access to the network. When operation of the network does not tolerate any down time, it is possible to set up a protected configuration for the Access Point to greatly reduce the possi-bility of this occurrence.Two or more Access Points can be configured identically, each with its own independent antenna. In this scenario, Remotes will associate with one of the available Access Points. In case of a failure of that AP, the Remotes will quickly associate with another Access Point, re-estab-lishing connectivity to the end devices. Because only one Access Point operates at any given time, collisions between APs is not possible.1.4.3 Collocating Multiple Radio NetworksMany networks can operate in relatively close physical proximity to one another provided reasonable measures are taken to assure the radio signal of one Access Point is not directed at the antenna of the second Access Point.RemoteRemoteRemoteRemoteAccess PointLAN/WANREPEATERLANLANLAN
05-4446A01, Rev. C Mercury Reference Manual 15The Network Name and the Association ProcessThe Network Name is the foundation for building individual radio net-works. Remotes in a network with the same network name as an Access Point (AP) unit are associated with that AP. The use of a different Network Name does not guarantee an interfer-ence-free system. It does, however, assure that only data destined for a unique network is passed through to that network.Co-Location for Multiple Networks It may be desirable to co-locate Access Points at one location to take advantage of an excellent location that can serve two independent net-works. Configure each network with a unique Network Name, and install each APs antenna with at least 10 feet of vertical separation to minimize RFI.To co-locate APs, configure them with Time Division Duplex (TDD) Sync set to GPS Required. Configure all APs that are within range of each other with the same pattern, but with a unique Hop Pattern Offset. For more information, see Frequency Control Menu on Page 60.NOTE: Transceivers are shipped with the Network Name set toMDS-Mercury as a factory default.Can radio frequency interference (RFI) disrupt my wireless network?When multiple radio networks operate in close physical proximity to other wireless networks, individual units may not operate reliably under weak signal conditions and may be influenced by strong radio signals on adjacent bands. This radio frequency interference cannot be predicted with certainty, and can only be determined by experimentation. If you need to co-locate two units, start by using the largest possible vertical antenna separation between the two AP antennas on the same support structure. If that does not work, consult with your factory representative about other techniques for controlling radio frequency interference between the radios. (See A Word About Radio Interference on Page 156 for more details.)1.5 GE MDS CYBER SECURITY SUITEToday, the operation and management of an enterprise is increasingly dependent on electronic information flow. An accompanying concern becomes the cyber security of the communication infrastructure and the security of the data itself.

05-4446A01, Rev. C Mercury Reference Manual 212.1 OVERVIEWGE MDS recommends that you set up a tabletop network to verify the basic operation of the transceivers. This allows experimenting with net-work designs, configurations, or network equipment in a convenient location. This test can be performed with any number of radios.When you are satisfied that the network is functioning properly in a benchtop setting, perform the field installation. Complete information for field installation, including mounting dimensions and antenna selec-tion, is provided in INSTALLATION PLANNING on Page 149.NOTE: It is important to use a Network Name that is different fromany currently in use in your area during the testing period.To simulate data traffic over the radio network, connect a PC or LAN to the Ethernet port of the Access Point and PING each transceiver several times.2.2 STEP 1CONNECT THE ANTENNA PORTSFigure 2-1 shows the tabletop arrangement. Connect the antenna ports of each transceiver as shown. This provides stable radio communica-tions between each unit and prevents interference to nearby electronic equipment.Invisible place holderFigure 2-1.

22 Mercury Reference Manual 05-4446A01, Rev. CNOTE: Use attenuation between all units in the test setup. The amountof attenuation required depends on the number of units testedand the desired signal strength (RSSI) at each transceiverduring the test. In no case should a signal greater than —50 dBmbe applied to any transceiver in the test setup. GE MDS recom-mends an RF power output level of +20 dBm from the AP.Remote power is not setable. (See Radio ConfigurationMenu on Page 58.)2.3 STEP 2CONNECT THE PRIMARY POWERThe primary power at the transceivers power connector must be within 10.5—30 Vdc and be capable of continuously providing 30 Watts. Typ-ical power consumption for 13.8 Vdc and 24 Vdc operation are listed in SPECIFICATIONS on Page 162.A Phoenix two-pole power connector with screw-terminals is provided with each unit. Strip the wire leads to 6 mm (0.25"). Be sure to observe proper polarity with the positive lead (+) on the left and negative (—) on the right, as shown in Figure 2-2.NOTE: The transceiver typically requires about 30 seconds to power up, andmight require several minutes to associate with another unit, if GPSis required for time synchronization. GPS is required for all configurations except when Free Runsingle-channel (non-frequency hopping) operation is used, whichmight be possible in some low-interference environments.Only use the transceiver with negative-ground power systems. Make sure the polarity of the power source is correct.Invisible place holderFigure 2-2. Power Connector(Polarity: Left +, Right —)CAUTIONPOSSIBLEEQUIPMENTDAMAGE
05-4446A01, Rev. C Mercury Reference Manual 232.4 STEP 3CONNECT PC TO THE TRANSCEIVERConnect a PCs Ethernet port to the LAN port using an Ethernet cross-over cable. The LAN LED should light. Alternatively, you can use a serial cable to connect to the COM1 port (Figure 2-3 on Page 25).2.5 STEP 4REVIEW TRANSCEIVER CONFIGURATION2.5.1 Getting StartedStart by logging into the Access Point radio. This is done first because the Remotes are dependent on the APs beacon signal to achieve an associated state.Once the Access Point is up and running, move the computer connection to each of the Remote units, log-in at each unit, review their configura-tion, set their IP addresses, Network Name, and frequency configura-tion, then wait for each AP to achieve an associated state.With all units associated, you will be ready to connect and test your data services.2.5.2 ProcedureThe following is a summary of the configuration procedure that must be done on each unit in the system. Key parameters are shown on the Embedded Management System overview (Figure 3-1 on Page 32). A lists of parameters is located in two tablesTable 4-5 on Page 140 and Table 4-7 on Page 142. Detailed information on using the Management System can be found in MS INTRODUCTION on Page 31.NOTE: The Management System supports the use of configurationfiles to help consistently configure multiple units. These areexplained in Configuration Scripts Menu on Page 119.2.5.3 Basic Configuration Defaults Table 2-1 provides a selection of key operating parameters, their range, and default values. All of these are accessible through a terminal emu-lator connected to the COM1 serial port or through a Web browser con-nected to the LAN port (see Figure 5-1 on Page 149 for hookup).NOTE: Access to the transceivers Management System and changesto all parameters requires entering a security password.
24 Mercury Reference Manual 05-4446A01, Rev. CFor benchtop evaluation, configure:¥Frequency Mode = Single Channel¥Single Frequency Channel = 0¥RF Bandwidth = 1.75¥TDD Sync = Free RunFor more information on configuring these parameters, see Frequency Control Menu on Page 60.A unique IP address and subnet are required to access all IP-based man-agement interfaces (telnet, SSH, SNMP, and Web), either through the LAN port or remotely over-the-air.2.6 STEP 5CONNECT LAN OR SERIAL DATA EQUIPMENTConnect a local area network to the LAN port or a serial device to the COM1 (DCE) port. The LAN port supports any Ethernet-compatible equipment. This includes devices that use Internet Protocol (IP).Figure 2-3 on Page 25 shows the interface connectors on the front panel of the transceiver.NOTE: The use of shielded Ethernet cable is recommended forconnection to the radios ETH port. The radio meets regulatoryemission standards without shielded cable, but shieldingreduces the possibility of interference in sensitive environ-ments, and is in keeping with good engineering practice.Table 2-1.

05-4446A01, Rev. C Mercury Reference Manual 313.1 MS INTRODUCTIONThe transceivers embedded management system is accessible through the COM1 (serial) port, the LAN (Ethernet) port, and using over-the-air Ethernet. Telnet, SSH, HTTP/HTTPS, and SNMP are the Ethernet-based interfaces. Essentially, the same capabilities are avail-able through any of these paths.For support of SNMP software, a set of MIB files is available for down-load from the GE MDS Web site at www.GEmds.com. An overview of SNMP commands can be found at SNMP Agent Configuration section on Page 53 of this manual.The transceivers Management System and its functions are divided into seven functional groups as listed below.¥Section 3.3, BASIC OVERVIEW OF OPERATION (beginning on Page 40)¥Section 3.4, CONFIGURING NETWORK PARAMETERS (beginning on Page 43)¥Section 3.5, RADIO CONFIGURATION (beginning on Page 58)¥Section 3.7, SECURITY CONFIGURATION MENU (beginning on Page 85)¥Section 3.13, PERFORMANCE OPTIMIZATION (beginning on Page 127)¥Section 3.12, MAINTENANCE/TOOLS MENU (beginning on Page 113)Each of these sections has a focus that is reflected in its heading. The section you are now reading provides information on connecting to the Management System, how to navigate through it, how it is structured, and how to perform top-level configuration tasks. Figure 3-1 on Page 32 shows a top-level view of the Management System (MS). 3.1.1 Differences in the User InterfacesAlthough there are slight differences in navigation among the user inter-faces, the content is very similar. You will notice a few differences in capabilities as the communications tool is driven by limitations of the access channel. Figure 3-2 and Figure 3-3 on Page 33 show examples of the Starting Information Screen as seen through a console terminal and a web-browser, respectively.

View of the MS with a Browser(Selections at left provide links to the various menus)3.2 ACCESSING THE MENU SYSTEMThe radio has no external controls or adjustments. All configuration, diagnostics, and control is performed electronically using a connected PC. This section explains how to connect a PC, log into the unit, and gain access to the built-in menus.
34 Mercury Reference Manual 05-4446A01, Rev. C3.2.1 Methods of ControlAccess the units configuration menus in one of several ways: ¥Local ConsoleThis is the primary method used for the exam-ples in this manual. Connect a PC directly to the COM1 port using a serial communications cable and launch a terminal com-munications program such as HyperTerminal (found on most PCs by selecting Start>>Programs>>Accessories>>Communica-tions>>HyperTerminal). This method provides text-based access to the units menu screens. Console control is a hardware-based technique, and is intended for local use only (maximum recom-mended cable length of 50 ft./15 m).¥Telnet or SSH*Connect a PC to the units LAN port, either directly or via a network, and launch a Telnet session. This method provides text-based access to the units menu screens in a manner similar to a Local Console session. You can run Telnet sessions locally or remotely through an IP connection. ¥Web Browser*Connect a PC to the units LAN port, either directly or via a network, and launch a web browser session (for example, Internet Explorer, Firefox, etc.). Enter the IP address of the device to be managed into the browsers address field.This method provides a graphical representation of each screen, just as you would see when viewing an Internet web site. The appearance of menu screens differs slightly from other methods of control, but the content and organization of screen items is similar. Web browser sessions may be run locally or remotely using an IP connection.* When connecting directly to a radio, a crossover cable is required. When connecting using a network, switch, or router, a straight-through cable is required.3.2.2 PC Connection and Log In ProceduresThe following steps describe how to access the radios menu system. These steps require a PC to be connected to the units COM1 or LAN port as shown in Figure 3-4 on Page 35.

05-4446A01, Rev. C Mercury Reference Manual 45VLAN Configuration MenuThe VLAN Configuration menu (Figure 3-13) becomes active and vis-ible when you enable VLAN Status on the Network Interface Configura-tion Menu, and you press the Enter key.CAUTION:The VLAN Status parameter must be consistent at both theAccess Point and Remote radios in order for data to flowcorrectly. Failure to do so might result in data not being trans-ported correctly even when the radios are in an associated stateand able to communicate over-the-air. About Virtual LAN in Mercury A VLAN is essentially a limited broadcast domain, meaning that all members of a VLAN receive broadcast frames sent by members of the same VLAN but not frames sent by members of a different VLAN. For more information, refer to the IEEE 802.1Q standard.The transceiver supports port-based VLAN at the Ethernet interface and over the air, according to the IEEE 802.1Q standard. When VLAN Status is enabled, the wireless port of both AP and remote radios act as a trunk port. The Ethernet port of an Access Point radio is normally configured as a trunk port. This type of port expects incoming frames to have a VLAN ID tag and sends outgoing frames with a VLAN tag as well.The Ethernet port of a Mercury radio can be configured as an access port or as a trunk port. When the Ethernet port of a Mercury radio is configured as VLAN Access Port, the radio tags incoming traffic with a VLAN ID, and strips the tag before sending traffic out. This VLAN is known as the DATA VLAN. Additionally, a second VLAN is assigned for other traffic that is terminated at the radio, such as SNMP, TFTP, ICMP, Telnet, and so on. This is known as the MANAGEMENT VLAN. Traffic directed to the integrated terminal server that handles the serial ports is assigned to the DATA VLAN.When the Ethernet port of a remote radio is configured as a VLAN trunk, the radio expects all incoming Ethernet frames to be tagged, and passes all outgoing frames as received from the wireless link, with the unchanged VLAN tag.

Note that the IP address is dif-ferent even though it is the same physical unit. This is because this IP address is defined for a different VLAN.
48 Mercury Reference Manual 05-4446A01, Rev. CDHCP Server Configuration (Data and Mgmt)A transceiver can provide automatic IP address assignments to other IP devices in the network by providing DHCP (Dynamic Host Configura-tion Protocol) services. This service eliminates setting an individual device IP address on Remotes in the network, but it requires some plan-ning of the IP address range. One drawback to network-wide automatic IP address assignments is that SNMP services might become inacces-sible as they are dependent on fixed IP addresses.You can make a network of radios with the DHCP-provided IP address enabled or with DHCP services disabled. In this way, you can accom-modate locations for which a fixed IP address is desired.NOTE: There should be only one active DHCP server in a network. Ifmore than one DHCP server exists, network devices mightrandomly get their IP address from different servers every timethey request one.NOTE: Combining DHCP and IEEE 802.1x device authenticationmight result in a non-working radio if the DHCP server islocated at a Remote radio. If possible, place the DHCP serverat the AP location.A DHCP server can be run at a Remote, but it is not recom-mended if 802.1x Device Authentication is in use and if the APgets its IP address from the DHCP server on the Remote. Inthis case, the Remote cannot authenticate to allow the AP toget its address, because the AP needs an address to perform802.1x device authentication. This results in an unsolvablecondition where the AP needs to get an IP address from DHCPat the Remote, but it cant get the address until it is authenti-cated.Invisible place holderFigure 3-15.
