The accessory connector in the back is lacking the required signals so we’ll use front MIC connector for TX audio, PTT and the headphones socket for RX audio.
Digirig audio cable pinout:
GX16-8F pin 1 (MIC) → 3.5mm TRRS ring 1 (RIG_AFIN)
GX16-8F pin 2 (STBY) → 3.5mm TRRS ring 2 (PTT)
GX16-8F pin 7 (GND MIC) +
GX16-8F pin 8 (GND) → 3.5mm TRRS sleeve (GND)
3.5mm TRS tip (PH) → 3.5mm TRRS tip (RIG_AFOUT)
3.5mm TRS sleeve (GND) → 3.5mm TRRS sleeve (GND)
This cable is now available in store at:
headphones jack adapter is required, something like this:
Hey K0TX, sorry to dig up an old thread but I am trying to wire this up for a similar setup. I’m running a Kenwood ts-140s and a ts-440 on my desk. Since the 140 doesn’t have CAT anyway, I was trying to use the standard Kenwood 8pin Mic jack as well. That way I could run the audio only setup through either unit.
My question is do the two GND Jack’s get soldered together? Or actually, all three(Seperate headphone connection)? Or should they be isolated some how?
Connect pins 7 & 8 together - Digirig doesn’t have separate ground for chassis/PTT/audio.
The sleeve on the headphone socket is likely connected to the ground/chassis. You can connect or leave unconnected that in the cable.
