  Page 36E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Part F - Operational FeaturesMultistream functionality (SIDcodes)The E Series sends data messages in packets. A feature of the ESeries is that an address can be embedded in each packet. Thisaddress is called the stream identifier code (SID).By configuring a user serial port for a specific SID code, it ispossible to steer messages to similarly configured ports betweenradio modems. In effect, it is possible to use the multiple serialports available on the E Series, to enable multiple protocols toshare the same RF channel. The SID codes also facilitate the useof other features such as TView diagnostics. Unique selectiverouting, repeating, and data splitting functions available in the radiomodems configuration allow data steering and bandwidthmanagement in complex systems.See Part I - TView+ Management Suite - Programmer and Part J -TView Remote Diagnostics and Network Controller for details.Collision Avoidance (digital andRFCD based)Where multiple “un synchronised” protocols co-exist on a common“multiple access” radio channel, there is always a possibility thatboth “hosts” may poll different “remote” devices at the same time. Ifboth devices attempt to answer back to the single master radio atthe same time, it follows that a collision could occur on the radiochannel.To facilitate the operation of multiple protocol operation on theradio channel, a transparent collision management system has beenimplemented : See Part I - TView+ Management Suite - Programmerfor details.Digital Collision Avoidance SystemIf the “multiple access master” has been configured for full duplexoperation, it is possible to use the inbuilt collision avoidance signalingsystem.Once the master radio receives a valid incoming data stream from aremote, a flag within the “outbound” data stream is used to alert allother remote devices that the channel has become busy. Remotedevices wishing to send data will buffer the message until the channelstatus flag indicates that the channel is clear. A pseudo-random timingvalue is added to the retry facility to ensure that waiting remotes do notretry at the same time.RF Carrier Detect RSSI based CollisionAvoidanceIn half duplex systems, the receiver’s RF carrier detect is used toinhibit the transmitter whilst a signal is being received.Digipeater OperationA feature of the E Series radio modems is the ability to internallyrepeat data packets to provide stand alone repeater facilitieswithout the need for external intelligence.This is done by programming “SID Codes” to “Repeat” a stream orrange of streams. Wizard templates can be used to simplify setupof this and other features.See Part I - TVIEW+ Management Suite for details.TVIEW+ DiagnosticsThe E Series has an inbuilt remote configuration and diagnosticsutility.This facility allows transparent remote access to the keyconfiguration and operating parameters of the radio.See Part J - TView Remote Diagnostics and Network Controller fordetails.Part F   Operational Features

Ltd.Part G  CommissioningCheck DC power connector for correct voltage (10-16VDC) andpolarity, BEFORE plugging in the power connector.Power-upUpon power up, the radio will self test and shortly after the greenpower LED will be displayed.Failure of the power LED to light indicates no power, or failure ofthe fuse due to incorrect polarity or over-voltage.Other failure such as fatal internal errors will initiate error modesindicated by a flashing sequence of all LEDS red, followed by oneor more green LED’s to indicate the nature of the failure (see Part E– Getting Started: LED Indicators and Test Outputs).LED IndicatorsWill depend on the system architecture. If the device is a remote sitereceiving a base station with a constant carrier, then the RXSIG/SYNC LED should be green to indicate healthy reception of thewanted signal.If the site has been configured as a constantly transmitting base station,then the PWR/TX LED should show red.In other types of systems, TX and RX bursts would be indicated bythe RX or TX LED’s as above.Data flow to and from the user ports is indicated by the TXD/RXDLEDs for each port.(See Part E – Getting Started: LED Indicators and Test Outputs.)Data Transfer IndicationsBi-colour LEDs are provided to indicate RS232 data beingtransmitted and received on each data port. A RED flash indicatesa byte (or bytes) of incoming data from the serial line which will betransmitted to air, and a green flash indicates a byte of datareceived “off air” being released onto the serial line.If data is being sent to the radio modem and the Data LED doesnot flash RED, this may indicate a wiring or configuration problem.Check that the TX and RX data lines are correctly wired (see Part E– Getting Started: LED Indicators and Test Outputs).Also check that character set and parity settings (i.e. N,8,1 etc) areset identically at the terminal and the radio modem. Note that someincorrect settings of the character set parameter can still producetransmittable data, even though the data will not be understood bythe application.Antenna Alignment and RSSITestingOnce the RXSIG LED is lit, it is possible to confirm RX signal strengthand align a directional antenna by monitoring the RSSI output.This DC voltage appears at Pin 9 of Port B.A ground reference can be obtained from chassis ground or Pin 5 ofPort A or B.The chart below shows Pin 9 voltage as it relates to signal strength.Part G  CommissioningLink Establishment and BERTestingOnce communications has been established, it is possible to confirmthe packet error rate performance of the radio path, and thus estimatethe BER figure.There are a number of tools provided to do this. The easiest is to usethe “indicative packet error test” provided within the TVIEW+Diagnostics under “statistical performance tools”. Alternatively, it ispossible to use hyper terminal, or other packet test instruments orPC programs to run end to end or perform “loopback” testing.Please note that when using a “loopback plug” some understanding ofthe packetising process is necessary, since each “test message’ mustbe carried in a single packet for meaningful results to be obtained.Note also that in PTMP systems, allowance must be made forcollision potential if other data is being exchanged on the system.VSWR TestingVSWR testing is achieved using specialized VSWR testingequipment, or a “Thruline” power meter that measures forward andreverse power.VSWR is the ratio between forward and reflected transmitterpower, and indicates the health and tuning of the antenna andfeeder system.VSWR should be better than 3 to 1, or expressed as a power ratio,<6dB or no more than 25%. To activate the radios transmiter forVSWR testing, use:a) An RTS loopb) A system port PTT plugAnalog RSSI Output Characteristics - E Series Data Radio00.511.522.533.544.55-120-110-100-90-80-70-60-50-40RF Level (dBm)RSSI (DC Volts)
  Page 38E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Part H  MaintenanceRoutine  MaintenanceConsiderationsThe E Series hardware itself does not require routine maintenance.However all radio products contain crystal frequency references,and the stability of these crystals changes with time. The effect ofthis is that the product will slowly drift off frequency, and eventuallyit will require re-calibration. E Series radios are designed with highquality, low drift specification references, to ensure a longmaintenance free lifespan. The length of this lifespan will dependon the severity of temperature extremes in the operatingenvironment, but is normally 3–5 years. Extended frequency driftcan be detected using TVIEW+ Diagnostics “Freq error” parameter.Generally, recalibration is achieved by replacing the radio in thefield with a spare, and returning the radio to a service centre for re-calibration and specification testing at moderate cost.Routine maintenance should be performed on external equipmentsubject to greater environmental stresses including antennas, RFfeeder cables, backup batteries and cooling fans (if required). Thismaintenance should include testing of site commissioning figuressuch as received signal strength, VSWR, P/S voltage etc.Part H  Maintenance

Ltd.Pull Down Menus and Toolbar ButtonsThe items on the pull-down menus can be selected either directly witha mouse or using the ALT key in combination with a HOT KEY (egALT-F to select the file menu).  Several of the functions within eachmenu are also available on the toolbar (click once to select).File MenuThe file menu allows the user to load (open) or save configuration dataas well as to quit the program.  The files are saved with an “.cfg” fileextensionOpen (also available on the toolbar)This function is used to load an existing configuration file that can beused to directly program the radio or to use as a starting point to editconfiguration parameters.  Note that a session must be establishedwith the unit by initially reading the configuration parameters from theunit prior to being written to a unit.If in file mode the modulation type will not be displayed. If in local/remote mode and a file that was saved from local/remote mode isopened, then modulation type will be imported and used, but only if itis valid for the connected hardware. If not then the units readmodulation type will be used.Save (also available on the toolbar)This function is used to save the current configuration parameters to afile for future recall.If in “file mode” only basic RF, Port and System parameters aresaved and re called. If in local/remote mode then modulation type issaved and re called.Print (also available on the toolbar)This function prints out the configuration data to the default printer in astandard format.  There are no options for this item.This should be used if a complete record is required for site/unitconfiguration. Firmware/Modulation/Diags/Hardware type are allprinted.Exit (also available on the toolbar)This function terminates the program. The user is requested to confirmthis selection before exiting the application.Modem MenuThis radio menu allows configuration data to be readfrom and written to the unit (remote radio or basestation) using the selected PC serial port connection(see Settings menu). The action of reading theconfiguration establishes a session with the unit.Communications is maintained with the unit to ensurethat the session remains open. If the session has been lost due to datatransmission errors or disconnection of the programming cable it willneed to be re-established to ensure any updated configuration is writtensuccessfully to the unit.Read (also available on the toolbar)This function establishes a session with the unit, reads configurationdata from the unit and displays it in the programmer main window.When selected a dialogue window appears prompting the user tochoose whether the unit to read is local (connected directly to the serialport or remote (connected over the air to the unit connected to serialport). Unit no. (serial no.) musty be entered and the stream SID codeis “on” (default =0)). After configuration data is read from the unit it isavailable for editing and writing back to the unit or saving to a file. Theprogress of data transfer to or from the unit is indicated by a messagewindow as well as a rotating indicator in the bottom right hand cornerof the main window.Write (also available on the toolbar)This function writes configuration data displayed in the main window tothe unit and reboots the unit. When selected a dialogue windowappears prompting the user to confirm whether to proceed.  A progressindicator in the bottom right hand corner of the main window isdisplayed while data is being read. This selection is only available if asession has been previously established and maintained with the unit.Part I  TVIEW+ Management Suite - Programmer
Page 43E Series Data Radio – User Manual © Copyright 2002 Trio DataCom Pty.

Select “Yes” to send acommand to the unit to cancel the new configuration changes and toclose the session.The configuration settings will revert to their previous values if the datacommunications circuit with the unit has been interrupted after the newchanges have been made, but before they have been verified, as justdescribed, then the unit will automatically discard the new changes. A“Timeout Error” message will appearin the event of such aninterruption and the programmer will revert back to file mode.After configuration data has been written the session with the unit isclosed and the programmer goes back to file modeNOTE: In general any change made on the programmer screen mustbe written to the unit using this function before it becomes permanentlystored. Changes to Power Adjust, Mute Adjust and Tx/Rx Trimhowever do take immediate effect to permit a tuning capability prior tobeing permanent stored.Cancel Session (also available on the toolbar)This function closes the session with unit and puts the programmerback into file mode. All configuration changes are discarded includingchanges to Power Adjust, Mute Adjust and Tx/Rx Trim.Wizard (also available on toolbar)This function permits the user to select standard configurations after theconfiguration from a unit has been read or a file opened. The user isprompted via a series of dialogue windows to select the desiredconfiguration that can then be written to the unit (remote radio or basestation).Part I  TVIEW+ Management Suite - ProgrammerClone ModeThis function permits writing of the same configuration data to severalunits. This feature is normally used for configuring data radio modemsconnected locally. The procedure is:• Read the configuration from the first unit• Configure the parameters (or Open a previously savedconfiguration file)• Select Clone Mode (Modem menu)• Write the configuration to the first unit• The changes will take effect when repowered• Connect the next unit• Write the next unit which establishes a session and recognisesthe unit serial number and type, and then configures the unit• Repower the unit for changes to take effect• Repeat the last 3 steps for the remaining units.SettingsThis menu permits selection of the PC serial port (COM1 to COM4)to be used for communications with the unit. COM1 is the defaultselection and if a different port is to be used it must be set beforeestablishing a session by reading the configuration from a unit.  Whilsta session is established with a unit this menu can not be accessed.HelpThis menu permits selection of help information using the Contentskey. Warnings regarding use of the programmer software using theWarnings key and version detail using the About key.Port A and Port B ConfigurationData from these two user ports is multiplexed for transmission over theair. Each port can be configured separately for the Character layer(Data speed, number of data bits, number of stop bits, parity), Packetlayer and Handshaking (flow control). Port B must be enabled ifrequired by setting the check box at the top of its configuration section.if Port B is off, the 16K memory is split equally between Port A Rx/Txbuffers (ie: 8K & 8 K). If Port B is on, then the 16K is split equallyacross Port A & B Rx/Tx buffers (ie: 4K, 4K, 4K & 4K).The following description is common to both ports.
  Page 44E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Packet LayerThere are two standard configurations and a custom configurationwhich can be selected by checking the appropriate control button to theleft of the description. There are essentially two basic modes ofoperation for the packet assembler and disassembler (PAD). The firstis where the PAD operates in a standard mode with data received atthe port being immediately sent over the radio channel. The second isa store and forward or delayed mode where whole data packets arereceived from the port before being sent over the radio channel. In bothcases data is sent over the radio channel in variable length frames anddelineation of these frames is dependent on the configuration selectedas well as the characteristics of the data stream received at the dataport.The packet layer configuration options which can be selected are:Standard (live framing)With standard live framing data received from the host by the modemis immediately placed into a frame and transferred onto the radiochannel.  This avoids placing “store and forward” delays in the datatransmission.If a stream of characters is received by the modem, then severalcharacters at a time may be placed into the same frame.  The numberof characters in the frame depends mainly on the respective baudrates of the user port and the primary channel baud rate of the modem,as well as the level of overheads experienced on the radio channeland the user data stream.For example a constant stream of 300 baud user data placed onto a9600 baud channel will result in 1 character per frame beingtransmitted.  If the user baud rate was lifted to 9600,N,8,1 with acontinuous data stream, then the frame size would settle to about 16characters plus 32 overhead bits.  If collision avoidance is enabled asmaster the average frame size will increase to 32 characters plusoverhead bits.The number of data bits associated with the user data stream will alsohave an effect on the average size of a frame.  For instance thenumber of stop bits, and number of data bits per character.The system designer must choose the best compromise of all theabove items to ensure the most efficient method of data transmission.Note: The first character is always packetized and sent by itselfregardless of all the above variables.ModbusThis selection configures the PAD driver with options automatically setto implement the MODBUS protocol. eg: 5 mSec timer.CustomOther configurations of the PAD driver can be selected via the Custombutton which displays a dialogue box to permit selection of severalconfiguration options as follows:SLIP / DIAGNOSTICSSLIP is a well known protocol for transferring binary datapackets over a data link. Each data packet is delineated by<FEND> characters, and a substitution mechanism exists thatallows these characters to be included in the data packet.Appendix B describes the SLIP protocol which is usedextensively in UNIX(tm) based systems, and is closelyassociated with TCP/IP networks.The diagnostics controller package uses the SLIP protocol tocommunicate between base station and remote modems.DNP-3 / IEC870This selection configures the PAD driver to implement the DNP-3Protocol and IEC870 Protocol.Pull Down Menu SelectionThe PAD driver can be configured for a number of vendorspecific protocols by selecting the desired option.Part I  TVIEW+ Management Suite - ProgrammerCharacter LayerThere are two standard formats and a custom format that can beselected by checking the appropriate control button to the left of thedescription. The standard formats are:• 9600,N,8,1  (data speed = 9600 bps, no parity, 8 data bits, 1stop bit)• 4800,N,8,1  (data speed = 4800 bps, no parity, 8 data bits, 1stop bit)A non-standard format can be selected via the Custom button thatdisplays a dialogue box to permit selection of data speed, parity,number of data bits and stop bits. Once selected the OK button shouldbe used to complete the selection. The custom selection is alsodisplayed in the main window below the Custom button.
Page 45E Series Data Radio – User Manual © Copyright 2002 Trio DataCom Pty. Ltd.Custom FormatThis selection permits PAD driver to be configured in a variety ofways and requires a greater understanding of the system design.For the modem to successfully transmit its packets (or frames) ofdata over the radio channel, it must be told on what basis todelineate data packets received at the data port. Once the end ofa data packet has been received at the port the data frame isclosed and transmission over the radio channel commences.Delineation of data packets can be configured to occur via anycombination of:• A predefined minimum time delay between packets receivedat the port. Typically the time delay would reflect the absenceof a couple of characters in the data stream at the specifieduser port baud rate.• Limiting the maximum number of characters which can be putin the data frame sent over the radio channel.• Receipt of a selected end of message (EOM) character at theport. An ASCII carriage return (character 13) is often used forthis purpose.As each data frame to be transmitted over the radio channel hasoverhead data consisting of checksums and SID codes.  Thesystem designer must determine the best compromise betweenthe ratio of overhead versus user data which depends on packetsize and user data packet transmission latency.The fields which can be configured are:•Character Input timer: Set the input timer value in ms or enterzero to disable.  Range 0 - 255.•Maximum Frame Size: Set the maximum number ofcharacters or enter zero to disable.  Range 0 - 4095.•EOM Character: Select the check box to the left of thedescription to enable and enter the EOM character as adecimal value.  Range 0 - 255.HandshakingIf the standard PAD is selected (i.e. any settings apart from SLIP/Diagnostics), then flow control can be either hardware handshaking,XON/XOFF protocol or none.The XON/XOFF flow control is not possible when using either theSLIP/Diagnostics protocol.The Handshaking section of the screen allows the selection of either ofthe handshaking methods as well as allowing handshaking to bedisabled.Details of the two handshaking methods are given below.HardwareThe modem acts as Data Communications Equipment (DCE) andsupplies to the host controller the following interface signals:Data Set Ready (DSR)Data Carrier Detect (DCD)Clear To Send (CTS)Receive Data Output (RXD)The host controller must act as Data Terminal Equipment (DTE) andsupplies to the modem the following interface signals :Data Terminal Ready (DTR)Request To Send (RTS)Transmit Data Input (TXD)• DCDDCD has several modes of operation. It is set to TRUE whendata is being transferred from the modem to the host - RXD lineactive.  The signal is asserted approximately 500ms before thestart bit of the first character in the data stream and remains forapproximately 1 character after the last bit in the data stream. Theother modes of operation are dependent on the advancedsettings.• DSRDSR is permanently set to TRUE.• CTSThe CTS is a signal from the modem to the host informing thehost that the modem is able to accept incoming data on the TXDline. It responds to the actions of the RTS line similar to theoperation of a “standard” line modem.The CTS is FALSE if the RTS line is FALSE. Once the RTS lineis set to TRUE (signalling that the host wants to send some datato the modem on the TXD line), then the CTS will be set TRUEwithin 1ms, if the modem is capable of accepting more data.The CTS line will be set to FALSE if the transmit buffer in themodem exceeds 4075 bytes, or the number of queued framesexceeds 29 to ensure that no overflow condition can occur.Part I  TVIEW+ Management Suite - Programmer
  Page 46E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.• RTSThe RTS line is used for two reasons.  The first is to assert theCTS line in response to RTS. The RTS line can also be used tokey up the transmitter stage of the modem.• DTRThe DTR line is used for flow control of data being sent from themodem to the host controller.  When the host is able to acceptdata it sets this line to TRUE, and if data is available within themodem, it will be sent to the host.  If the host cannot accept anymore data, then it sets the DTR to FALSE, and the modem willstop all transmissions to the host.• Xon/XoffIf the flow control mechanism is XON/XOFF then the modemuses the standard ASCII control codes of DC1{^Q=11(Hex)=17(Dec)} for XON and DC3{^S=13(Hex)=19(Dec)} for XOFF. The DTR input line is totallyignored.NOTE: There is no substitution mechanism employed in theXON/XOFF protocol, so care must be taken when transferringbinary data to ensure that invalid flow control characters are notgenerated.AdvancedThis button provides access to the advanced features of the portconfiguration. When selected a dialogue box appears which permitsselection of the source for the port DCD output signal.DisabledThis selection disables the DCD output on the port. This selection isnot permissible if hardware based flow control has been selected.RF Carrier DetectThis selection causes DCD to be asserted at the onset of a receivedRF signal being detected. This will generally occur severalmilliseconds before data is transmitted from the port.Data Detect (RS485 Flow Control)This selection causes DCD to be asserted when data is about to betransmitted from the port. This option is not available if handshaking isset to “None” or “Xon/Xoff”.RF ParametersThis section of the main window permits adjustment of transmitter andreceiver, radio channel modulation scheme, frequency trim andadvanced features.TransmitterThe transmitter can be configured for transmit frequency and powerlevel.FrequencyThe required transmit frequency in MHz can be entered in the displayfield.  The programmer checks that the selected frequency is in therange for the particular model of radio and provides warnings if not.Power AdjustThe currently selected transmit power is displayed below the button indBm. The power level can be adjusted by selecting this button whichdisplays a dialogue box. The up/down keys, or a typed in value, canbe used to select the required power level in dBm steps. There aretwo methods for setting the power.Part I  TVIEW+ Management Suite - Programmer
Page 47E Series Data Radio – User Manual © Copyright 2002 Trio DataCom Pty. Ltd.• Using Factory CalibrationTo use the factory calibration of the radio the desired power is setimmediately using the OK button in the dialogue box. Thismethod permits the transmit power to be set without energisingthe transmitter. Note that although the transmit power has beenadjusted it must be written to NVRAM using the modem “Write”function to ensure it is retained after a power on reset.• Using a Power MeterTo overcome manufacturing variations in the power setting amore accurate setting of power can be achieved by the selectingthe “Test With Meter” button in the dialogue box. This displaysanother dialogue box warning the user that the transmitter is aboutto be energised and that the power meter used should be able tohandle at least 10 Watts from the modem.Selecting OK in this warning dialogue box will energise thetransmitter which will also be indicated by the red transmit LEDon the unit. The power is adjusted using the up/down keys untilthe required power level is obtained. Selecting OK will retain thepower setting and turn the transmitter off. Note that although thetransmit power has been adjusted it must be written to NVRAMusing the modem “Write” function to ensure it is retained after themodem is rebooted.Selecting “stop test” will stop and leave you in power adjustbox. “Cancel” will stop test and take you back to the mainwindow.ReceiverThe receiver can be configured for receive frequency and mute level.FrequencyThe required receive frequency in MHz can be entered in the displayfield.  The programmer checks that the selected frequency is in therange for the particular model of radio and provides warnings if not.Mute AdjustThe currently selected mute level is displayed in the main windowbelow the button in dBm. The mute level can be adjusted by selectingthis button which displays a dialogue box. The up/down keys, or atyped in value, can be used to select the required mute level in dBmsteps. Whilst a session is in progress with a unit the mute leveladjustment is live. Selecting OK will retain the mute level setting. Notethat although the mute level has been adjusted it must be written toNVRAM using the modem “Write” function to ensure it is retained afterthe modem is rebooted.Whilst the modem is capable of receiving extremely weak radiosignals, and successfully extracting the data content from thewaveforms the mute level should be set to assist the modem infiltering out unwanted signals. Unwanted signals can be the result ofbackground noise or interference. The mute level should be set at alevel above these unwanted signals and at a level low enough todetect the wanted signal. Detection of a received signal above themute level is indicated by the “RxSig” LED on the unit.Setting of a correct mute level at a base station is critical if collisionavoidance is operational in a point to multipoint system. In this situationdetection of “noise” instead of a valid transmission from the remotemodems will effectively “lock out” all of the remote units fromaccessing and using the channel.Due to normal manufacturing variations the actual mute level mayvary by several dBm to that selected. If a more accurate adjustmentis required an unmodulated signal of the correct frequency and desiredthreshold level can be applied to the radio modem’s antenna connector.ModulationThe radio modem utilises a DSP to control the modulation of transmitsignals and de-modulation of received signals. This provides greaterflexibility in the ability of the radio modem to support new modulationschemes whilst maintaining compatibility with existing modulationschemes.The currently selected modulation scheme is displayed in the mainwindow below the select button. The modulation scheme can beadjusted by selecting this button which displays a dialogue box. Thedesired modulation scheme can then be selected from the pull-downmenu in the dialogue box and retained using the OK button.In the case of 12.5kHz channel radio modems the presently supportedmodulation schemes include:• 9600 12.5kHz ACA E Series. This is a new 9600bpsmodulation scheme available in E Series products whichsupports a significantly reduced delay between detection of avalid RF carrier signal and demodulation of user data.• 4800 12.5kHz ACA D Series. This is a current 4800bpsmodulation scheme used in the D Series products to providebackward compatibility.Part I  TVIEW+ Management Suite - Programmer

The frequency trim can be adjusted live by selecting thisbutton which displays a dialogue box. The up/down keys can be usedto select the required frequency offset in steps pre-determined by theradio modem. Selecting OK will retain the frequency trim setting. Notethat although the frequency trim has been adjusted it must be written toNVRAM using the modem “Write” function to ensure it is retained afterthe modem is rebooted.This facility permits correction for drifts in the frequency referencecaused by component ageing.  For example, a standard crystal mayvary in fundamental frequency operation over 1 year by one part permillion. An adjustment range of ± 10ppm, displayed in Hz, has beenallowed for and if this is insufficient the unit should be returned to thedealer/factory for re-calibration.AdvancedThis button permits setting of advanced features. When selected adialogue box appears which permits configuration of the type ofreceived data clock alignment method.In the case of full duplex units the receiver is always active and is notinterrupted by transmissions from the unit as would be the case for halfduplex units. In this situation it is not necessary, or desirable in thecase of a base station, for the recovered data clock alignment to beremembered between bursts of received signals. In this situation the“Receiver Full Duplex” check box to the left should be selected.NOTE: For half duplex units the “Receiver Full Duplex” check boxshould not be set.System ParametersThis section of the main window configures the PTT control, collisionavoidance, stream setup for routing of data, advanced features andprovides unit information.PTT (Press To Talk) ControlRF transmission can be configured to occur permanently,automatically on data received at Port A or Port B, or RTS beingasserted on Port A or Port B. A PTT timeout facility can be configuredto limit the period for which the transmitter is enabled. Each option isselected by setting the control to the left of the description on the mainwindow. When PTT is active the “Tx” LED on the unit is illuminatedand RF power is being fed to the antenna.Permanent TxThis will cause the transmitter to be permanently enabled (keyed) anddisplays another dialogue box warning the user that the transmitter willbe energised immediately after the configuration is written to the unit.Selecting OK confirms this setting. The other PTT selections aredisabled when this option is selected.NOTE: This option is only available for half duplex units when beingprogrammed locally.Auto On DataThis will cause the transmitter to be enabled (keyed) automatically ondata received at Port A or Port B and included in a complete frame fortransmission over the radio channel. The maximum period for whichthe transmitter will be enabled is limited by the PTT timeout setting.From Port A RTSThis will cause the transmitter to be enabled (keyed) on Port A RTSbeing asserted. The maximum period for which the transmitter will beenabled is limited by the PTT timeout setting. Applications which relyon establishing a link ahead of data being transferred require thismethod of activation.From Port B RTSThis will cause the transmitter to be enabled (keyed) on Port B RTSbeing asserted. The maximum period for which the transmitter will beenabled is limited by the PTT timeout setting. Applications which relyon establishing a link ahead of data being transferred require thismethod of activation.In the case of 25kHz channel radio modems the presently supportedmodulation schemes include:• 19200 25kHz ACA E Series. This is a new 19200bpsmodulation scheme available in E-Series products whichsupports a significantly reduced delay between detection of avalid RF carrier signal and demodulation of user data.• 9600 25kHz ACA D Series.

Page 49E Series Data Radio – User Manual © Copyright 2002 Trio DataCom Pty. Ltd.Stream SetupThis button brings up a dialogue box to permit editing of StreamIDentifier (SID) codes which are used by the modem as theaddressing mechanism for data stream routing. A SID code can beplaced at the start of each data frame as it is sent over the radiochannel.  The receiving modems use this code to determine how toroute the data message. The modem supports simultaneous operationof both Port “A” and Port “B” over the one radio link, along with theinclusion of a diagnostics data stream.Each port is independant and fully supports one of four options whichcan be chosen as described below. Note that the port B parametersare greyed out when port B is not enabled.The following diagram illustrates the structure of the stream routingfunction for each data port.SIDFilterSID Adder/TranslatorPort Data InRx Data InTx Data OutPort Data OutStream RouterUser,TrunkRepeat,TranslateUser PortThis option is selected by clicking on the User Port button and filling inthe RXSID and TXSID fields to the right.In the User Port mode (Referred to in the previous programmer asMUX/DEMUX mode) all SID code operations are performedtransparently to the user.  Data placed into a user port which has beenassigned a specified SID code, will only be received by a modem atthe other end of the radio link that has a user port assigned with thesame SID code.In this way, Port “A” and Port “B” can be assigned different SIDcodes, thereby separating the data streams.Two SID codes values are available for each user port RXSID andTXSID.  The RXSID codes apply to the data being received by themodem, and the TXSID codes apply to the data being transmitted bythe modem.  This allows for different transmit and receive codes ifrequired, but generally they would be both the same.A situation where Tx and Rx SID codes may be different is in arepeater configuration.  In this type of application all data messagessent to the repeater will be “repeated”.  Thus by having different Txand Rx codes a control unit will not “hear” its own transmission andremotes will not hear the reply from any other remote.If the diagnostics facility is installed in the modem, then it too has a pairSID codes.  The diagnostics data simply uses a different data streamor streams to the user data, but is processed internally by the modem.If access to the diagnostics facility is required, similar to when thediagnostics utility is used with the modem, then the data portconcerned and the diagnostics stream, must have the same SIDcodes assigned to them. Alternatively the System port can be used,which is 19.2K, Slip.(Previously TXSID was referred to as SIDA2 or SIDB2 and RXSIDwas referred to as SIDA1 or SIDB1 for ports A and B respectively).Trunk StreamsIn the Trunk Streams mode, data that is inputted into the modem fortransmission must have a SID code appended to the start of the datapacket by the user.  The modem does not do it as in the User Portmode of operation.  When a data packet is received by the modem, itis passed through a SID code filter which is bounded by a lower andupper limit of SID codes.  The SID code is not stripped off from theuser data.For instance the lower bound is 03 and the upper bound is 07.  If amessage is received with a SID code of 02 appended it would not bepassed to the user.  If a message is received with a SID code of 04then it is passed to the user, with 04 at the start of the frame.The SID codes can range from 0 to 255, and physically consist of thebyte value of the code i.e. a code of 156 is equivalent to “10011100”binary.PTT TimeoutThe PTT timeout facility is used to disable the transmitter if it exceedsthe designated time. The timeout value can range from 1 to 255seconds and the facility is disabled by setting a zero value.The timeout value chosen for this should be set according to systemrequirements which may include:• Prevention of a remote unit remaining keyed up and locking outall other remote units in a point to multipoint system.• Limiting the period a remote unit remains keyed up to preventbattery drain in a low power application.NOTE: If a PTT timeout occurs before completion of a datatransmission data will be lost.Part I  TVIEW+ Management Suite - Programmer
  Page 50E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.To select the Trunk Streams option click on the Trunk Streams buttonof the port to be used and fill in the fields to the right.  The “From” fieldis for the lower SID code limit and the “To” field for the upper SID codelimit.NOTE: When using Trunk Streams an unambiguous packetdelineation scheme (eg. SLIP) should be used so that the SID code inthe user data can be decoded correctly.Repeat StreamsThe modem is capable of operating in a repeater mode.  Each userport can be configured as a separate repeater.  The associated userports are effectively disconnected from the “outside world” when inrepeater mode.  Data received from the radio channel is passeddirectly to the transmitter, and placed back onto the radio channel.The repeater must receive a complete frame of data before it isretransmitted.  In some systems this store and forward delay may besignificant, and careful selection of maximum frame sizes configured atthe source unit must be considered to minimise the delay.To enable the mode for the port click the Repeat Streams button andselect the range of SID codes on frames to be repeated.Translate StreamsThis is essentially a hybrid of the User Port and Repeat Streamsfunctions available on a port.  Whereas the latter repeats a range ofstreams, this function instead translates one stream to another, bydemultiplexing one stream (defined by Rx SID), and re-transmitting itwith a new stream address (defined by Tx SID).NOTE: Data is not presented to the user ports.Diagnostics ProcessorThe Diagnostics Processor uses several streams defined by the rangeof SID codes. The diagnostics commands received on each streamare sent back over the same stream. The Diagnostics Processor is anoption which must be enabled before this section of the menu willbecome active.Diagnostics RepeatThis option can be toggled on and off simply by clicking thebutton.Some applications will require that the master unit in a point tomultipoint system to repeat diagnostics frames only (i.e. themaster modem is not set up as a repeater).This will be the case when the system diagnostics controller isconnected to a remote unit in the system, and it polls the systempopulation from this point.  The master unit must retransmit anydiagnostic frames that are not addressed to itself onto theremainder of the population.AdvancedThis button permits setting of advanced system parameter features.This presently includes enabling the diagnostics facility within the unit.Once enabled the diagnostics utility can be used to monitor theperformance of the unit.The Enable Diagnostics button should be selected and the 8 characterdiagnostics key code entered prior to selecting OK. If the key code isaccepted or has been previously entered the Enable Diagnosticsbutton will be greyed out. Contact your supplier for Key Codepurchase.Collision AvoidanceIn a point to multipoint system the master unit (usually a base station)can transmit at any time and the remotes will all receive the broadcastsignal.  However, if more than one remote unit transmits at a time,then a collision will occur during the multiple transmissions, resulting ina loss of data from one or more units.Two collision avoidance mechanisms have been included in themodem.  The standard (Digital) method utilises a signalling channelwhich is embedded in overhead data transmitted over the radiochannel. The second method utilises detection of a carrier signal topostpone transmission of data. Both methods require configuration ofseveral options for successful operation.The desired option for collision avoidance is selected by checking thecontrol button to the left of the description on the main window.NoneWhen selected this turns off all collision avoidance mechanisms. Thisshould only be used in point to point applications.DigitalThis is the standard method of collision avoidance and utilises achannel busy indication bit in the signalling channel transmitted to allremotes for control. When selected a dialogue box appears andseveral options must be configured:Part I  TVIEW+ Management Suite - Programmer
Page 51E Series Data Radio – User Manual © Copyright 2002 Trio DataCom Pty. Ltd.• Mode – “Master” or “Remote”. When the master unit receivesa valid transmission from a remote unit it sets the channel busyindication bit. This busy bit is interpreted by the other remotes tonot transmit. Once the transmission from the first remote endsthe master unit resets the busy bit to indicate the channel isnow clear to transmit on. The master unit, which is normally abase station, takes about 5ms to detect a transmission from aremote unit and set the channel busy indication bit on the radiochannel. During this period collision of remote transmissionscan still occur and is unavoidable. NOTE: The master canonly be a full duplex unit.• Backoff Method – “Retry after Tx Attempt” or “Delay before TxAttempt”. The method chosen is system dependent and canonly be configured if the mode is “remote”. The former is bestused when data responses from remotes are largelyasynchronous. The latter is best used when this is not thecase.• Backoff Timing – “Maximum Slots”, “Time per Slot”. This canonly be configured if the mode is “remote”. When a remote isready to transmit data but it finds the busy bit from the masterset it holds back its transmission for a random “backoff” timeafter which it tries to transmit data again. This ensures thatmodems waiting to be allowed to transmit do not re-attempt todo so at the same time. The “Maximum Slots” (1 to 16) andthe “Time per Slot” (1 to 255ms) are used to calculate thebackoff time by multiplying the slot time by a random numberbetween 1 and the maximum slot number. For example if thetime per slot is 30ms and the maximum slots is 4, the randombackoff times can be 30, 60, 90 or 120ms.As the channel busy indication bit is critical for reliable operation defaultinterpretation of this bit is defined in the remote units. If the mastermodem stops transmission (or has not yet started) the remote willinterpret that the channel is busy and will not transmit until the mastercomes on line.Carrier DetectThis method of collision avoidance utilises a carrier transmitted to allremotes to indicate that the radio channel is busy. When selected adialogue box appears and several options must be configured:• Mode – “Master” or “Remote”. When the master unit receivesa valid transmission from a remote unit it transmits a carriersignal to indicate busy. Of course the master will also initiate atransmission if it has data to send. The transmitted carrier isinterpreted by the other remotes to not transmit. Once thetransmission from the first remote ends the master unit stopstransmission to indicate the channel is now clear to transmit on.The master unit, which is normally a base station, takes about5ms to detect a transmission from a remote unit and transmit acarrier signal. During this period collision of remotetransmissions can still occur and is unavoidable.NOTE: The master can only be a full duplex unit and cannot bepermanently transmitting. For half duplex and simplex systemsall units should be set as “Remote” (no Master).• Backoff Timing – “Maximum Slots”, “Time per Slot”. This canonly be configured if the mode is “remote”. When a remote isready to transmit data but it detects a carrier signal from themaster set it holds back its transmission for a random “backoff”time after which it tries to transmit data again. This ensures thatmodems waiting to be allowed to transmit do not re-attempt todo so at the same time. The “Maximum Slots” (1 to 16) andthe “Time per Slot” (1 to 255ms) are used to calculate thebackoff time by multiplying the slot time by a random numberbetween 1 and the maximum slot number.

Ltd.Part J  TVIEW+ Management Suite -  Remote Diagnostics & Network ControllerIntroductionThis section covers the operation of the Remote Diagnostic andNetwork Management Controller Software Version 3.7.X or greater.OverviewThe Diagnostic Controller is a Windows© based program, that can berun on a standard desktop or laptop PC.The software runs in the 32 bit Windows environment and offers manyoptions and configurations which are easily accessible via pop-upwindows.  These include group or timed polling, remote switching ofduplicated base stations, viewing of databases, logging and trending ofreal time parameters , etc.The Diagnostic Controller can be installed to run as a stand-alonepackage, or as part of the TView+ Management Suite.It is for use in conjunction with the D & E Series of data radio modemsand can be used for simple point-to-point links, or for more complexpoint-to-multipoint and multilayer link systems.The diagnostic facilities allow retrieval of packet statistics from eachradio modem.  These statistics are used to calculate Packet and BitError Rates, a units’ condition/health, network efficiency andbandwidth utilisation.The use of the diagnostics facilities provided by the controller gives theradio modem system designer and operator a powerful tool for both themaintenance and continuing reliability of their system.The general operating parameters that can be obtained from remotemodem units are:-• Last RSSI level.• Last transmitted power level.• Receive frequency offset.• Power supply voltage level.• Current internal temperature.These are displayed on the controllers screen in a “quick read” formatof bar graphs, as well as detailed response listings.For the E Series radio modems to operate with the diagnosticcontroller, they must be factory preset to include the diagnosticsresponse facilities or installed at a later stage (in the field) via theprogrammer. Contact you supply for details.The diagnostics data stream operates “alongside” the main user datastream.  No interference between the two streams occurs, so as faras the primary user of the data system is concerned, the diagnosticsdata does not exist.Features• 32 Bit Windows Based User Software.• Full graphical presentation.• Full SCADA style features such as database, trending,networking, etc.• Able to interrogate and display important operating parametersof each radio modem.• Provides performance data of any unit - good frames received,bad frames received, packet error rate, transmitted packetsizes, channel usage, etc.• Provides statistical Packet Error Rate (PER) performancecalculations for any unit.• Provides powerful network tools such as channel occupancystatistics, average received transmission duration, etc.• Can be set to background poll radio system for continuoussystem monitoring and logging.• Provides full time/date stamped Status and Alarm logging/reporting.  A relational database is created and managed usingMicrosoft Jet database engine Ver3.5.  The database file, whichis an “.mdb” file, can be accessed with external programssuch as Microsoft Access.System DescriptionGeneralThe diagnostics process is based on a series of polls being transmittedto the remote modem units with each modem having its own uniqueassigned address which is factory preset.When a diagnostic poll is received by a modem it checks to see if it isaddressed to itself, and if so, it responds with its diagnostic data backto the controller.  If it is not addressed to the modem, the modemsimply “passes the message on”, and does not respond to thecontroller.In a multilayer system, several “pass on’s” may occur before thedestination modem is reached.The modem’s diagnostic response message is addressed to thecontroller, and as each modem in the “chain” decodes this message itwill “pass it back”, eventually the message reaches the controller forprocessing.The controller software provides a database to hold the modem unitsassociated data (i.e. Serial number, assigned name, location, alarmlimits, SID code address, base station pairing information, status pollresponse data, alarms, etc).The units’ address is the serial number of the unit which is factorypreset.  The name is any mnemonic that the user wishes to attach tothe modem.  This name is then used to address the unit for access todiagnostic facilities.Part J  TVIEW+ Management Suite -Remote Diagnostics & Network Controller
  Page 54E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.The responses from the modem have boundary limits placed on them.If a response is outside these limits then an alarm is raised.  Forinstance, the DC supply volts can have a lower limit of 12V, and anupper limit of 16V.  Should a response to a poll received show that theDC volts is at 11V, then an alarm is reported.A unit can be excluded from a poll sequence by removing it from thepoll group.Intensive polling of a single unit is possible using the Individual pollingfacility.A poll “run” can be set up.  A time can be designated for the controllerto poll each of the modems in the system.  This may be useful forsystems that have a low traffic period where diagnostics can be“slotted in”, thereby spreading the data throughput of the system moreefficiently.The screen is divided into three main scrolling sections - Status Polls,Alarms and Base Station Activities.  The status poll section displayscurrent poll activity while the alarm section displays any polls alarmswhich have been reported.  The Base Station activity section displaysany changeovers that have occurred to Hot Standby Base Units - ifno Hot Standby Base Stations are employed within the system, thissection will remain blank.If base stations are employed in the system, then the two exciter unitscontained in one base unit can be paired together.  The excitersoperate in a mutually exclusive environment i.e. only one is active ata time.  When the exciters are to be polled, only the active one will besent a poll.The base exciters can be toggled, so as the other exciter unit in thebase can be polled if required.A relational database is created and managed using Microsoft Jetdatabase engine Ver3.5.  The database file, which is an “.mdb” file,can be accessed with external programs such as Microsoft Access.All polls and alarms are time and date stamped and saved to thedatabase.  All database entries can be sorted and printed.For some multilayer systems, Stream Identifier (SID) Codes mayhave to be added to the diagnostic data packets.  Each modem can beassigned a SID address (the default is 00) and the SID code featureenabled.Refer to Appendix A “Technical Notes” for further details of SID codeaddressing.The diagnostic core of each radio (Firmware Version 2.4.0 and above)stores packet statistics for later retrieval.  The Diagnostic controllersoftware uses these statistics to calculate packet and bit error rates,network efficiency, bandwidth utilisation, and radio link integrity.  Thesenetwork analysis features are an invaluable tool for larger networks.In the transmit direction, each radio modem can report the number of:-• data bytes transmitted (TxByteCnt).• frames transmitted (TxFrameCnt).With these counters one can then calculate average frame size,average frame rate and channel utilisation.In the receive direction, each radio modem can report the:-• Data bytes received (GoodByteCnt).• Good frames received (GoodFrameCnt).• Bad frames received (BadFramCnt).• Total time the radio has received signal (RSSIgoodTicker).• Lost synchronization count (LostSynchCnt).• Lost RSSI count (LostRSSICnt).These counters can be used to calculate average frame size, averageframe rate, channel occupancy, channel utilisation and link integrity.Radio modems with Firmware Revisions 2.4.x and above have theadvanced statistical counters as noted above.  Firmware revisionsbelow this (i.e. 2.3.x) only have Good Frame count, Bad Framecount, Lost RSSI count and Lost Synch Count available.  Thediagnostic controller will detect which firmware the radio has, and onlyreport the available counters.All these features combine to provide a powerful tool for the systemoperator.Modem ConnectionThe diagnostics controller normally connects via a COM port on thecontroller PC and the “System Port” on the radio modem (Port “A &B” can be used if required).NOTE: The controller can connect to any port of any data radiomodem within the system as long as the data radio port is configuredaccordingly. When “Settings” is selected, the controller will interogatethe computers coms ports and display the available ports. Possiblevalid com ports are 1-16 or “None”. Choose the desired port. Noneallows you to free the com port for use with other programs withoutexiting the diagnostic.The modem port must have its SID codes enabled, and have the SIDcode set to the system diags SID (normally this is set to “00”).The data format used is the SLIP protocol, running at 9600 baud, Noparity, 8 data bits and 1 stop bit.  Appendix B “SLIP Protocol”contains a detailed definition of the SLIP Protocol.COM1 of the controller PC is to be directly connected to the 9 way D-Min of the modem using a 3 wire interface (see drawing below).Should the PC have a 25 way connector, then the standard RS232,25 way to 9 way conversion should be used.Part J  TVIEW+ Management Suite -  Remote Diagnostics & Network Controller

This is obtainedfrom the label located on the unit or read from the unit using theProgrammer.  On base stations the exciter serial numbers must beread from the lid label or electronically with the programmer.SID Code (Diagnostic Stream Identifier)Is the SID code address number being used by the unit for thediagnostics stream.  This is normally set to 0.  Check the radio unitsprogrammed configuration for confirmation and or system configuration.Unit SeriesDefault to “E Series”, option on pull down box to select “ D Series”Poll Response TimeoutIs the time in seconds the Diagnostic controller will wait for a responsefrom the remote unit.  When a time out occurs, the controller will retry.If three poll attempts fail then the poll request is terminated, and a NoAcknowledge (No Ack) message will appear in the alarms window.One second is usually more than enough “wait” time.  In a multilayersystem, longer response times may be necessary.Alarm LimitsAllows the user to set thresholds for each unit which, when exceeded,will report an alarm. Default settings are provided for remote devicesand base stations.  These are selected by clicking on the appropriatebuttons presented.If the controller receives a status poll parameter result which is outsideany of the threshold settings, it will immediately retry, in case it wasan erroneous measurement.  If the next received poll result is stilloutside the threshold, the retries will continue until it has received astatus poll within the threshold settings, or three status polls.  If threepolls outside the required threshold are received, the average of thesepolls is displayed in the status poll window and the offendingparameter(s) appear as alarms in the Alarms window.Defaults drop down boxChoose either “Remote Modem Defaults” or “Base Modem Defaults”from the drop down list.  Click “Apply” to set the alarm limits to theselected defaults.  Click “Save” to save custom default values.Hot Standby Base PairingIs used when a Hot Standby Base is employed within the system.The two exciters contained in each base unit need to be “paired”together.  Since only one of the exciter-modems can be active (on-line) at any time, only one can answer a poll.  Thus the two should bepaired together so they are treated as mutually exclusive.This selection allows the user to pair the two radio modems, byselecting the other exciter with which the currently selected exciter isto be paired with.  The two units must of course exist in the databaseas independent serial numbers before they can be paired.Add New ButtonClick this button to add a new radio modem to the database.

Select the required com port speed (9k6 or19k2bps). Default is 19k2bps.Controller AddressNormally set to 0.  Networks which have multiple controllers active,should use different controller addresses, so responses from remotesare ignored if the poll was not sent by that controller.Enable SID CodesEnabled or disabled (Default enabled).  In some systems, externalapplication of SID codes is used as a method of giving the modems inthe system specific data addresses.  The modems are placed into the“stream routing” mode, and the user (e.g. Diagnostic controller)supplies the SID code at the start of each data packet to betransmitted.  In this way the user can “steer” the data flow through thegiven network path.Should the diagnostics controller be used in such a network then it tooneeds to append the data addresses or SID codes to the beginning ofall data messages sent.In the controllers database record for each modem, a field is suppliedwhere the user can select the SID code for that particular modem.  Byselecting the Diagnostic SID code that suits the system topology, thediagnostics data messages can be routed successfully to the correctdestination.Auto Logging ONWhen enabled all logging functions will be activated when polling isturned on.Alert TonesWhen enabled will emit a tone from the PC speaker or sound cardwhen Status poll alarms occur and/or Base Station change oversoccur.Tx Power Display UnitsSelect either “dBm” or “milli Watts” as the display units.

The Group and Timed pollfacilities will automatically cycle through a selected group of units at apredetermined interval (in seconds).  The Individual poll facility permitsintensive polling of a single unit at a selectable rate, independent of anyGroup polling that may be active at the time.When the modem is polled for the first time, the controller will poll (ask)the radio for its calibration constants and firmware revision (these canbe viewed in the “View” window under the File menu).  When thisinitialisation procedure is complete, status polling can commence.  Ifthe radio were to perform a “cold boot” for what ever reason (eg lossof power, cold boot command received, etc), the controller will detectthis and initiate the above initialisation procedure again and display“cold boot” alarm in “other”.If Hot-Standby base stations are employed in the system, then onlythe “on-line” unit will be polled.  If a hot standby changeover occurs atthe base, then the new “on-line” modem will be polled and the off-lineunit removed from the poll sequence.  A “Changeover” alarm will bedisplayed in the Base Station Activity screen.The status poll requests that are reported and displayed on the mainscreen are;• Temperature• Received Signal Strength• Transmitter Power• DC Supply Volts• Received Frequency Error• Time and dat stampedThe line above Status Polls is a “Processing Status Bar”.  It willdisplay messages about errors, warnings and poll processing.Poll Setup (Settings)Under the Polling menu option, choose “Setup...”  The Poll Settingsdialog box will appear.  Here you can set :Poll Repetition TimeIs the time in seconds (2 to 3600 secs) between each status poll of thegroup poll cycle.  Each unit in the poll group will be polled in turn, atthis time interval.Timed PollingAllows the user to schedule a period when the group poll willcommence.  This is a useful feature for systems that have times oflittle traffic loading such as the early hours of the morning.Start TimeTime at which the Timed poll cycle will commence.  The time formatwill be as per the regional settings.Number of CyclesThis is the number of times the controller will cycle through the pollgroup when the Timed Group poll commences.  Each unit in the pollgroup will be polled this number of times.Apply ButtonClick “Apply” to initiate any changes made in this dialog box.Poll Group SelectUnder the Polling menu, select “Poll Group Select...”This dialog box enables Adding/Removing of radios to/from theautomatic poll group.

The radio network controller can be configuredas either a Server or Client.  The Server will send poll information toeach attached client, depending on their access rights.Client groups can be set up.  Each Client can be assigned to oneclient group.  Each radio modem can be assigned to one or moreClient groups.A default Client group called “ALL” is automatically set up containingall radio units in the database.Client Groups Example:All Pumps TestTest Unit 1 Pump 1 Test Unit 1Test Unit 2 Pump 2 Test Unit 2Test Unit 3 Pump 3 Test Unit 3Pump 1Pump 2Pump 3In the above example, there are three client groups, ALL (the default),Pumps, and Test.  A Radio modem can be a member of more thanone group.Client Examples:• Central - This is the Diagnostic Server whichis attached to the radio network.• Test Client - This is a Diags controller in clientmode.• Pump Monitor - This is a Diags controller in clientmode.In the above example, the Central workstation, running Diagnostics inServer mode, is polling all the radios in the network and distributing thereceived messages to the attached clients.The Test Client and Pump Monitor are receiving Status poll and alarminformation from the Central server.  The Test Client will only receivepoll information for radios found in the “Test Client Group” i.e. TestUnits 1, 2 and 3.  The Pump Monitor will only receive poll informationfor radios found in the “Pumps Client Group” i.e. Pumps 1, 2 and 3.Networking - SettingThe Server should be configured properly first before any connectionattempts are made by clients.  It will always be safer to stop anypolling that may be in progress when making changes to the Serverclient set up.Local Host Settings TabIt is assumed that the workstation is running Windows, and has beenconfigured with the TCP/IP network protocol.• Open or create a radio database.• Under the Networking menu bar select “Settings” from themenu bar.• In the Networking window click the “Local Host Settings”button.• The Local Host settings will appear, which contains the ServerHost Name, IP address, Local Port and Password.• The Local Port is the socket number.

  Page 66E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Interpreting Poll ResultsGeneralThe results returned by the poll requests give an indication of systemperformance.  When a new modem is added to the database, defaultvalues are assigned for the limits of the returned results.  The user canassign different values to these limits as required, which is determinedby the fault tolerance level of their systems.RSSIThe default RSSI limits are set at -30 to -105 dBm(-110 dBm for Base/Repeater Station).  Above -30 dBm the front end of the receiver willsaturate and it is unlikely that signal levels much higher than this willever be reported. Below -105/-110 dBm the error rate may becometoo high for some applications.  In the modem the RSSI measurementis made periodically each 100mS, while R F carrier is being detected.Transmitter powerThe transmitter power limits are set at between 0mW and 20,000mW.The modems will normally be operating at a power level of 1 watt.The above limits are set to ±3dB of the nominal (3dB represents afactor of 2 for power measurements).The effect of a change in transmittal power can be transposed to thereceiver BER curves (3dB down at the transmitter is 3dB down at thereceiver).  The amount of variation tolerated will be determined by theRF path loss of the data link being used.If the modem is set to low power, then the transmittal power will benominally 200mW. Suggested limits for this would be 100mW and400mW (±3dB).For base station units or remote units set to high power, the nominaltransmitter power is 5 watts.  Suggested limits on these would be 2.5watts to 10 watts (±3dB).In the modem the reported transmit power measurement is given froma measurement made of the last transmission made by the modems.When the PTT is ON a periodic measurement is made of the transmitpower.  The modem stores this away and reports it when requested.TemperatureThe modem is specified to operate within the temperature range of -30°C to 65°C.  The defaults limits are set to -30°C and 60°C.  At65°C the modem goes into a high temperature foldback mode, whenthe power is reduced to the low power mode.  This is to reduce therisk of damage to the final stage of the transmitter at excessivetemperatures.The modem will operate outside this temperature range but it is notrecommended.Supply VoltageThe modem is specified to operate over a DC supply range of 11V to16V.  The default levels are set to 11.5V to 15.5V.  The modem will notoperate correctly outside these bounds and damage may occur withhigh voltage levels being applied.FrequencyThe frequency limits are set to ±3000Hz.  This is basically thedifference between the different ends of a data link.  If the differencegets much greater than this, data errors may occur (the modem willhave a degree of long term frequency drift of 1ppm / annum due to thephysical properties of internal components).Part J  TVIEW+ Management Suite -  Remote Diagnostics & Network ControllerNotes:1. Remote Tx power measurements will vary due to power setting variation which can have an    initial error of +/- 0.5 dB and final error of +/- 0.2 dB2.

Although not truly a“standard” it is so widely used that it has become the defacto standardfor serial interface in UNIX and many other networked systems.SLIP is a method of framing messages containing binary data, onasynchronous channels.  The asynchronous serial channel isconfigured for eight bit character size, no parity, and one stop.A specific binary code called FEND (Frame End, hexadecimalvalue=C0) is reserved to define a frame boundary.  Should this samecode occur in the data message to be transferred across the channelcontrolled under SLIP, then an escape sequence is used so that themessage byte will not be confused for a FEND.  This escapesequence, involves replacing the message hexadecimal C0 codewith a two byte sequence FESC, TFEND.  FESC (Frame Escape)is the binary code hexadecimal DB, and TFEND (Transposed FEND)is binary code hexadecimal DC.  Likewise, if the FESC characterever appears in the user data, it is replaced with the two charactersequence FESC, TFESC (Transposed FESC).  The TFESC is thebinary code hexadecimal DD.  The following table clarifies this.Abbreviation Description Hex.ValueFEND Frame end C0FESC Frame escape DBTFEND Transposed frame end DCTFESC Transposed frame escape DDAs characters arrive at the SLIP receiver, they are appended to abuffer containing the current frame.  Receiving a FEND marks the endof the frame, and consequently, succeeding bytes are considered partof the next frame.Receipt of a FESC code puts the SLIP receiver into “escaped mode”,causing it to translate a following TFESC or TFEND back to a FESCor FEND code, appending it to the buffer, and resuming it’s normalstate.  Receipt of any byte other than TFESC or TFEND while inescaped mode, is an error.  No translation occurs, and the SLIPreceiver leaves escaped mode.  A TFESC or TFEND received whilenot in escaped mode is treated as an ordinary character and storedaccordingly.  Reception of consecutive FEND characters, causes noaction to be taken (i.e. is not interpreted as zero length frames).An example of a typical SLIP frame is shown below.  The messageconsists of the string DA,C4,C0,C5,DB,20,BD,DC,DD.  The SLIPframe will be:-DA,C4,<FESC>,<TFEND>,C5,<FESC>,<TFESC>,20,BD,DC,DD,<FEND>     ==>            DA,C4,DB,DC,C5,DB,DD,20,BD,DC,DD,C0
