Dan, >From your message I am guessing that you are trying to set up a crossband repeater from VHF to UHF. Otherwise you will need to explain 2 mobiles and a "simplex repeater".
The rear 16 pin connectors have some pins that are fixed in function (mic audio, PTT, Gnd) and some that are assigned via software (type of audio output, indication of valid PL/DPL/carrier detection). The switching functions must be configured to be active atthe proper level (High or Low). Both radios will need to be properly configured. The configuration of the cable must be bi-directional; it must pass the COS, PTT, and audio signals in both directions, GND is comman between both units. Without the proper equipment and software to program the radios and documentation of the radio and the cable it's going to be rather hard to get things properly set up.
