PTT

Connectanappropriatecablebetweentheradio'sPTToutputandthetuner'sPTTInputAorBjack.Most

radioshaveaPTTinterface.However,itisessentialtocheckyourexcitermanualtodeterminethekeying

voltageandcurrent,especiallywitholderradios.TheTunerGeniusXLPTTlines

areopto‐isolated,buttheywill

nottoleratehighvoltagesoranACvoltage.Th erefore,bepreparedtoprovideakeyingbufferrelaydesignedfor

thetask,liketheAmeritron™ARB‐704amptotransceiverinterface.

i–Someoperatorschoosetouseakeyingbufferinallcasesas

"insurance"topreventanypossibledamage

totheexciterortunerduetopossibletransientvoltagespikesorRFingress.

BandData

Mostradiosuseoneoftheseprotocolstosendbanddatatoexternaldevices:

 BCD/PTBprotocol

ConnectyourradioorbanddecodertotheBCD/PTBInput

AorBCD/PTBInputBconnectoronthe

tuner.Thisconnectionrequiresnoadditionalconfigurationandworksautomatically.Banddataarriving

ontheBCD/PTBconnectionoverridesothersources.Seesection14.2.7,PTB/BCDConnectorPinout,

foradditionalinformation.Alsoseesection6.3.1.4,BandDataandFrequencyMeasurementbased

restrictions,in

thiscase.

 CATprotocol

Connectyourradio'sCAToutputtotheCATInputAorCATInputBconnectoronthetuner.Then,

configuretheCATprotocoldetailsusingtheTunerGeniusXLWindowsUtility.

 CI‐Vprotocol

Connectyourradio'sCI‐VoutputtotheCI‐V

InputAorCI‐VInputBconnectorusinga3.5mmTSorTRS

connector.ConfiguretheCI‐VprotocoldetailsusingtheTunerGeniusXLWindowsUtility.

 FrequencyMeasurement

TheTunerGeniusXL willmeasureanRFsignal'sfrequencyappliedtooneofitsinputsand

automaticallyswitch

intheappropriatetuningsolution.Thisbandswitchingmodeoftenrequiresthat

youdouble‐keybrieflybeforethefirstfulltransmissiontoallowthecorrecttuningsolutiontobeset.

Alsoseesection6.3.1.4,BandDataandFrequencyMeasurementbasedrestrictions,inthiscase.
