QUICKSTARTGUIDE
Below arethebasicstepsforinstallingthetransceiver.See INSTALLATION”onPage5ofthisguidefor
detailedinstructions.
1.Install and connecttheantennasystemtotheradio
•Usegoodquality,low losscoaxialcable.Keepthefeedline asshortaspossible.
•Presetdirectionalantennasin the directionof desiredtransmission.
2.Connect thedataequipmentto theradio’sINTERFACEconnector
•UseaDB-25Maleconnectortoconnect tothe radio. Connectionsfortypicalsystemsareshown
below.
•Connectonlytherequiredpins. Donot useastraight-throughRS-232cablewithallpinswired.
•VerifythedataequipmentisconfiguredasDTE. (By default, theradioisconfigured asDCE.)
3.ApplyDC powertotheradi
•Observeproperpolarity.Theredwireis thepositivelead;the black isnegative.
4.Set theradio’sbasic configurationwithaHa
•Set thetransmit frequency (TXxxx.xxxx).
•Set thereceivefrequency (RXxxx.xxxx).
•Setthebaudrate/datainterfaceparameters asfollows.Usethe BAUD xxxxxabc command,where
xxxxx equalsthedataspeed(110–38400bps)and abc equalsthecommunicationparameters as
follows:
a = Databits(7or8)
b =Parity(NforNone, O forOdd, EforEven
c =Stopbits(1or2)
(Example: BAUD 96008N1)
NOTE: 7N1,8E2and8O2areinvalidparameters andarenotsupportedbythetransceiver.
5.Verify properoperationbyobservingtheLED display
•RefertoTable7on Page14 foradescriptionof thestatusLEDs.
•Refinedirectionalantennaheadingsfor maximumreceivesignalstrengthusingthe RSSI command.

SupervisoryControl and DataAcquisition (SCADA)and distribution
automation,gasfield automation,waterandwastewaterSCADA,and

This is themostcommon application ofthetransceiver.Itconsistsofa

hostcomputerandremoteterminalunits(RTUs)orotherdatacollection
devices.Theoperationoftheradiosystemistransparenttothecomputer
equipment.
Often,however,aradio systemconsistsofmany widely separated
remoteradios.Apoint-to-multipoint orSCADA (SupervisoryControl
and DataAcquisition)systemmight beutilizedforautomatic,remote
monitoring ofgaswells,watertanklevels, electricpowerdistribution
systemcontrol and measurement,andsoon.
Theradio systemcanreplace anetworkofremotemonitorscurrently
linkedto acentrallocation vialeasedtelephoneline.At thecentral
officeofsuchasystem,thereisusually alargemainframecomputerand

Continuously-Keyed operation meansthemasterstation transmitteris
alwayskeyedand anRFcarrierisalwayspresent,evenwhenthereisno
datato send.Themasterstation isalwayssimultaneouslytransmitting
and listening.Usedifferent frequenciesto transmit and receive.Thisis
themethod usedin many MASsystems,asisshown in thetypical

Switched-Carrier operation isahalf-duplexmodewherethemastersta-
tion transmitteriskeyedto send dataand unkeyedto receive.Thetrans-
ceiverusesdifferent frequenciesfortransmitand receive.Thisprevents
different remotesfrom interfering witheachother,making it easierto

2IN TXD—TransmittedData. AcceptsTX datafromthe
connected device.
3OUT RXD—Received Data. Outputsreceiveddatatothe

4IN RTS—Request-to-SendInput.Keysthe transmitterwhen
RTS isatlogichigh.
5OUT CTS—Clear-to-Send Output. Goes logichigh afterthe

6OUT DSR—DataSetReady. Provides a+6 Vdc DSR signal
through a2.5k resistor.
