Quoted from Gexchange:So Try a dip switch 4 and 7 reset and a 6 and 8 reset. Let me know if you need instructions on how to do this
this will return it to factory defaults and clear anything.. Ive seen this fix this problem, other thing ive seen fix the issue is to reload the software. If that's bad, I don't think I/O I think Motherboard.

I considered the 2 switch reset, but if I recall, it never seemed to right many wrongs on the Ion platform as much as it corrected on the Force stuff.
The software reinstall is probably a good try before you order an I/O board. Surprisingly, the RX motherboards were pretty reliable. Much better than the Auroras and other Ions. I wish we had never bought those RXs. That’s when Merits stopped earning. 15 years ago we had 100 on the route. Today I have 3!
