Help - Current For Stepper Motor Driver AM882 - ProTuner

[GuitarCNC]

Hi everyone,

I have been struggling for weeks to build a serial cable to connect my AM882 drives to Protuner.
Would anyone provide the actual pinout of their cable? That would be so appreciated!!
I got the pinouts that are floating in diagrams all over the web but none work.

I had made this cable years ago and all was working, but I have lost that cable.
I am using the same PC which is dedicated to Protuner.

Thank you so much in advance.

Assuming that the current tuning is setting the winding current then the supply current from 68v will be much lower as the drivers in effect are switched mode PSUs.
