

FollowthestepsbelowtoinstallandconfigureVoyagerTelemetryRadio(VTR):

1. SelectthelocationfortheVTR.Mustbeanareafreeofwaterintrusionwitha

temperaturerangeof‐30to+55degC(‐22to130degF).

2. Locatethecoaxialcabletotheantenna.Thisshouldbeagoodquality,low‐losscable

thatisasshortaspossible.Thiscableshouldincludeanin‐linesurgearrestorto

preventlightningstrikedamagetotheradio.ThecableshouldhaveaBNC(F)

connectororanadapterwillbeneeded.

3. Locatethepowersource.TheVTRrequiresa9‐14VDCinputanddrawsabout1.5A.

PowerissuppliedviatheDB9connector(Pin5:+VDCandPin9:Ground)orplugon
