Solution was to replace the logic.

From a customer in the field who was having this issue and has the tools to program the backplane:
I was using 1WireHost on the picture that I previously sent you where it had the correct Serial # and cabinet. I just ran 1WireBackplane and that one comes up with the default Serial # and no cabinet type. Once I fix it there the game comes up with no issues.
It’s possible that that’s what might be happening initially and that’s why we are receiving the new cabinets with this error. AGS might be shooting the backplane using “1WireHost” instead of “1WireBackplane”. They verify that the Serial # and cabinet are programmed but when software is installed, it doesn’t recognize it because they didn’t use the proper app. Hopefully this helps.
