Thread: Autocom PTT/UHF cable wiring diagram?

    Autocom PTT/UHF cable wiring diagram?


    I'm installing an Autocom but taking it from its original box and mounting into a waterproof one in addition to shortening all the cables etc..

    The PTT cable goes into a 5 pin DIN along with the cable from the Uniden UH079SX UHF CB and then this DIN connects to another cable going to the Autocom.

    What I'd like to know is the connections for the above so I can fabricate a new cable.

    Failing that can anyone tell me how the PTT function works so I can knock one up myself.

    There are only 2 wires between the UHF and the autocom so I assume that when the PTT is hit these wires carry both the audio and some kind of control voltage on one of thepins to tell the UHF to transmit?

    Anyone shed light?

    Correction to last post.

    There are 3 wires from the UHF to the Autocom but cos there's a 2.6K ohm resistor in line with one of em my buzzer didn't pick it up 1st time but now the Ohmeter tells all. there's also a small capacitor and they're both assembled into the DIN plug.

    Soooooo.....anyone got a diagram or do I have to buzz it all thu?
