    Default GCAI to Serial Pinouts

    Hello,
    I am looking to create a GCAI to Serial connector from some old mics I have laying around. I want to sync an O3 head but from what I have read, I need the GCAI to serial cable.
    Does anyone have the pin-outs for it?

    Thanks

    So you might need a MAX232 or similar in that cable path to convert levels from standard RS232.
    Also before butchering a mic, you'd probably want to first verify that the mic cable actually even has those pins brought through since some of them use a lower conductor count cable to reduce cost and cable diameter.

    The magic is in the 1-Wire chip that tells the radio which accessory is connected. Years ago some guys on Batlabs reverse-engineered it and homebrewed one.
