I keep having issues with player 4 set up. I have been troubleshooting for over 2 weeks.
Can you be more specific?
What are the issues you're running into? Wiring? Re-programming the IPac?
What have you done for troubleshooting?
Do you have a multimeter and know how to do continuity and voltage checks?
Now as of today, one oof the switches isn't being recognized on player 3.
I assume that means the switch was working before, so it's not a case of having the wires connected to the NC (Normally Closed) and COM (Common) tabs instead of the NO (Normally Open) and COM tabs, right?
Which switch is it?
Is it the last switch on the ground daisy chain? (might be a bad crimp or break in the daisy chain)
Can you short the IPac input to ground and trigger the output? (could be a bad switch or a bad/loose connection or a damaged wire)
The question is: could I just leave as is and get a new smaller ipac board for player 3 and 4?
Let's define the problem before leaping to
that solution.

Or could I update the software?
I
really doubt that a firmware update will help.
