INTRODUCTION
The VWseriesRadioModemprovidesthe capabilityofashortrange,reliable
wireless point-to-point, point-to-multipointand meshnetworkRFdata
communicationslink.
The VWseriesmodemcan be used inavarietyofdatacommunications
applicationsthatrequireasimpletouseinvisibledatalink.The radiomodemis
designed tointerfacetoavarietyofhostdevices.Thesedevicesinclude
computers,receiptprinters,PLC s,dataloggers,SCADAdevicesand intelligent
controlsystems.
The serialdatatransferredoverthe radiolinkisnot altered; theoutput serialdata
streamisthe sameasthe inputserialdatastream.The radiomodemsprovide a
two-waydatacommunicationslinks,whereeachunitcanacceptserialdataand
alsooutputserialdata.
The VWseriesradiomodemsarefullyself-containedunits,requiringonlyan
external+5VDC (or+3.3VDC)powersourcetooperate.Theradiomodulesused
inthe radiomodemshavebeen selected tomeetthe requirementsofunlicensed
operationinthe internationalISMbands,and arethereforeacceptableforusein
manycountries.
