Here’s the image of the pinout from the linked manual: [image] Based on that the audio cable will look like this: GX16-6 pin 1 (MIC) → 3.5mm TRRS ring 1 (RIG_AFIN) GX16-6 pin 3 (PTT) → 3.5mm TRRS ring 2 (RIG_PTT) GX16-6 pin 5 (GND) → 3.5mm TRRS sleeve (GND) not clear if EXT. AF is the received audio. If it is then: GX16-6 pin 2 (GND) → 3.5mm TRRS tip (RIG_AFOUT) otherwise 3.5mm TRS tip (EXT.SP) → 3.5mm TRRS tip (RIG_AFOUT)

Please take a look at the thread to answer your question.
