2Quick Start Guide - EB450 Base Station2.1 Typical Radio Setup2.0 Mounting and EnvironmentalConsiderationsThe EB450 Base Station is housed in a 2RU 19” rackenclosure. The 4 mounting holes on the front panelshould be used to secure the unit to the rack.The radio should be mounted in a clean and dry location,protected from water, excessive dust, corrosive fumes,extremes of temperature and direct sunlight. Please allowsufficient passive or active ventilation to allow the radiomodem’s heatsink to operate efficiently.All permanent connections are made at the rear of theunit. This includes: Power, Antenna, CommunicationsPorts, Digital I/O and System Port. The front panel has anadditional System Port connection point for easy access.(see Fig 1 for details)Fig 22.1 Full Duplex ConsiderationsThe EB450 is designed for continuous full duplextransmission. An automatic thermostatically controlled fanwill operate whenever the internal temperature exceeds50 degrees Celsius.2.2 External Duplexer ConsiderationsThe EB450 is normally supplied with seperate Tx and Rxports for connection to an external duplexing system.Depending on the frequency band of operation and theTx/Rx frequency split, internal band reject duplexers areavailable.
Quick Start Guide - EB450 Base Station 33.0 Connecting Antennas and RFFeedersThe RF antenna system should be installed inaccordance with the manufacturers notes.The RF connectors used on the EB450 radio are N Typefemale connectors. Always use good quality low lossfeeder cable, selected according to the length of thecable run. Ensure all external connections arewaterproofed using amalgamating tape.Preset directional antennas in the required direction usinga compass, GPS, or visual alignment and ensure correctpolarisation (vertical or horizontal).4.0 Communications Ports4.1 System Port - RJ45The System Port (available at the front and rear of theunit) is a multi-function interface used for:•Programming / Configuration of the radio•Remote Diagnostics connectionsTo access these functions use the standard E SeriesSystem Cable assembly (RJ45 Cable and RJ45 to DB9Adaptor).System Port pinout assignments:Pin 1 System port data out (RS232)Pin 2 System port data in (RS232)Pin 3 Not usedPin 4 ShutdownPin 5 Not usedPin 6 Not usedPin 7 GroundPin 8 External PTTSpecial user pinouts:•Shutdown (Pin 4) - Active low for power save function•External PTT (Pin 8) - Provides a manual PTT overridefacility for enabling the transmitter.

4Quick Start Guide - EB450 Base Station4.2 User Interfaces - Ports A & BEach user port (A & B) is wired as a RS232 DCE,configurable for no handshaking (3-wire) interface, or forhardware or software (X-on/X-off) flow control. In mostsystems flow control is not required, in which case only 3wires need to be connected between the radio and theapplication device.4.3 Typical pins used:•Pin 2 (RxD) - data output from the radio modem,• Pin 3 (TxD) - data input to the radio modem,• Pin 5 (SG) - signal ground.Refer to User Manual for further details of other cableconfigurations.RS232 Connector Pin outs (DCE)Port A and B, Female DB94.4 Activating the TransmitterIn most systems, the transmitter by default is controlledautomatically by the radio when it has data to transmit.In some systems, such as full duplex point-to-point linksor full duplex point-to-multipoint base stations, it isdesirable to run the transmitter all the time (hot keyed).Two mechanisms are provided to do this:•the radio modem can be configured to transmitcontinuously whenever powered, or•the radio modem can be configured to transmitwhenever an external RTS signal (Pin 7) is applied toone (or either) user ports. (To simulate an externalRTS input, loop pins 6 to 7).To operate in these modes, the radio must be configuredvia the programming software.Caution: When the radio is configured to transmitcontinuously, ensure an RF load is present BEFOREapplying power to the unit.Fig 6Fig 7
Quick Start Guide - EB450 Base Station 55.0 Power Supply and Protection(fusing)The EB450 radio modem is designed and calibrated tooperate from a 13.8Vdc regulated supply, but will operatefrom 11-16 volts (filtered) DC.The current requirement is typically 230mA in receivemode, and will vary in transmit mode according to RFoutput power level (typically 1.3-2.5 amps).NOTE: Allow an additional 80mA (approx.) for LED bargraph indicatorsCaution: There is NO internal replaceable fuse, andtherefore the radio modem MUST be externally fused withthe fuse holder provided (a 5 amp fast-blow fuse).6.0 TVIEW+ Management Suite -Radio ConfigurationThis TVIEW+ Management Suite allows a number offeatures including: Configuration (Local - serial, orRemote - over-the-air), Remote DiagnosticsFacilities andFirmware Upgrades.The configuration wizard can be used to provide QuickStart generic templates for the types of systemsarchitecture you wish to employ.Example: Local configuration session -1 Attach the programming cable from the PC to theSystem Port of the radio (see fig 6 & 7 )2 Launch TVIEW & Select “Programmer”3 Select “Read” the radio4 Change the configuration as required5 Select “Write” the parameters back to the radioRefer to User Manual for detailed operation of advancedfeatures.Fig 7The radio is designed to self protect, and will blow theexternal fuse if the voltage exceeds 16Vdc, or if reversepolarity is applied.The radio modem can also be damaged if there is anypotential difference between the chassis-ground, RS232signal ground, power (-) input, or antenna coaxial shield.Before connecting any wiring, ensure all components areearthed to a common ground point (please pay particularattention to 24V PLC power systems where convertersare used).Connect the antenna and RS 232 plugs BEFOREapplying power to the unit.Lastly, before inserting the power plug, please re-checkthat the polarity and voltage on the DC power plug iscorrect using a multimeter.
6Quick Start Guide - EB450 Base Station7.0 Optimising the Antenna forVSWR and best RX signalOnce the unit is operational, it is important to optimise theantenna tuning.In the case of a directional antenna, it will be necessaryto align the antenna for the best received signal.This can be done by using the (0-5Vdc) output on Pin 9(see fig 9) of Port B to indicate signal strength (RSSI).This voltage can be converted to dBm using the chartbelow.8.0 LED Indicators & Test outputs8.1 Radio is PoweredIf all the LEDs are off, no power is reaching the radiomodem.Successful power-up is indicated by the “PWR” LEDindicating a continuous (healthy) GREEN state. Note thatthis LED is turned RED when the transmitter is active.8.2 Voltage ErrorIf the voltage is too high(>16Vdc) or too low(<10Vdc), anerror message will be displayed on the status LED’s byilluminating all four (4) LED’s RED.8.3 Hardware ErrorA hardware error is indicated on any one of the status LED’sby illuminating solid RED. In the case of a hardware error,the unit must be returned to the service point for repair. In thiscase please consult the User Manual for further informationon the error indicated, and record the result with the servicereturn information.Analog 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)Fig 9LED LegendVSWR testing is achieved by activating the radio’stransmitter using:a) An RTS loop as described in Section 4.4, orb) A system port PTT plug as described in Section 4.1Refer to the User Manual for further details of VSWRtesting.
Quick Start Guide - EB450 Base Station 78.4 Received Signal IndicatorThe “RX/SYNC” LED indicates the state of the receiver.If the LED is off, no signal is being received.A RED indication shows that an RF carrier is beingreceived, but no data stream can be decoded. This willbreifly happen at the very start of every valid receivedtransmission or may indicate the presence ofinterference, or another user on the channel.A continuous GREEN indication shows that the modem islocked and synchronised to the incoming signal, and hasexcellent Bit Error Rate (BER). Any losses ofsynchronisation (BER errors) are shown as a visible REDflicker of the LED.Note: This might only be apparent on a PTMP slave whenonly receiving.8.5 Data Flow “breakout” LEDsThere are also two LEDs to indicate data flow into andout of the two user ports.Input data to be transmitted is shown as a RED flash, andreceived data to be output to the port is shown as aGREEN flash.If data is aternately flowing in and out quickly, then theindicator appears orange.DC Supply:Indicates the supply input voltage at the exciter module.Typically 13.8Vdc.Indication: <10Vdc no LED’s on, 10-10.9Vdc LED’s RED,11-15.6Vdc all LED’s GREEN, >=15.7Vdc last LED RED.Tx Power:Indicates forward RF power output as measured at theTX antenna port. Typically +37dBm.Indication: <20dBm no LED’s on, 20-40.6dBm (11.5W)LED’s GREEN, >=40.7dBm last LED RED.Tx Drive:Indicates exciter drive level. Typically +20dBm.Indication: <10dBm no LED’s on, 10.0-25.9dBm LED’sGREEN, >=26.0dBm last LED RED.Rx Sig:Indicates receive signal strength. Typically -85 to -65dBm.Indication: <-120dBm no LED’s on, -120 to -110.1dBmLED’s RED, >=-110dBm LED’s GREEN.RxFreq. Offset:Indicates offset of receiver AFC - useful in determiningfrequency drift. Typically 0kHz.Indication: Single GREEN LED to indicate current value,<-3.6kHz or >+3.6kHz LED is RED. No signal, all LED’sOFF. Note: 5 second peak hold circuitry.9.1 Test ModeThe Bar Graph indicators have a Test Mode, which cyclesall LED’s for correct operation (before returning to theirnormal operation). To activate this mode, simply depressthe ON / OFF button while applying power to the unit.9.0 Bar Graph IndicatorsThe bar graph indicators on the front panel providevariable information regarding the performance of theBase Station.
