GM338 Radio Programming

[mistkhan]

Hi,

We are integrating GM338 Radio with dispatch system. For the radio to work with Dispatch system we need to program Accessory Pin 3 for PTT and Pin 8 for COR (Active Low). We were able to configure Pin 3 for PTT, however we couldn't program Pin 8 as there is no COR type available. Can someone provide information for programming Pin8 as COR (Active Low)

Radio Details:
Model:GM338, AZM25RHF9AA5
CPS Version: R06.12.05

Thanks in Advance.

Look for PL/DPL^CSQ DET. Goes low with valid RX tone or DPL PLUS receiver carrier squelch active.

This is a open collector transistor, you will need a pull up resistor, 10K works good to 13 volts.
