Normally associated with power and loudspeaker connections, the 15 pin D connector

can also provide audio in and out plus two programmable pins, one, an input and the

other an output. These can be programmed to go either logic high or low when certain

conditions arise. They can also provide a cross-connected PTT arrangement where one

radio receiving a signal forces the other to go to transmit and with cross-connected

audio lines, anything received on one radio is re-transmitted via the second.

The circuit on the following page shows how this can be achieved.

This group of 4 connections

are used to provide the facility

connector rebroadcast

function.

The pin 3, ignition sense contact used to

ensure the radio switches on when there

is no control head and therefore no other
