Vertex-standard vxr-1000 radios

I have several of the VERTEX-STANDARD VXR-1000 radios.
I would like to interface these with a DigiRig.
Does anyone have a wiring schematic available for these interconnections.


I came across this pinout:

Based on it, the audio/PTT cable will look like this:

DB9 pin 1 (GND) → 3.5mm TRRS sleeve (GND)
DB9 pin 2 (Transmit Audio) → 3.5mm TRRS ring1 (RIG_AFIN)
DB9 pin 6 (Receive Audio) → 3.5mm TRRS tip (RIG_AFOUT)
DB9 pin 9 (PTT) → 3.5mm TRRS ring2 (RIG_PTT)

Please report your results if you end up building this cable
