Well, I guess I have to open "The DCS Companion" and read up on the AIU. It is reversing two switches in the remote. Switch no. 13 is switch 14, and 14 is 13. 13 is on AIU 1, and 14 is on AIU 2. The reason I said the wiring is correct is that I did continuity checks from the AIU terminal to the end of the wire. They are going where they're supposed to. I terminated the wire on a terminal block, and added the switch machine and remote controller. I have spent all day tracing wires and testing combinations of these 3 elements. The best I can do so far is that on one switch, the DCS remote is correct but the remote controller is flipped, and on the other switch the DCS is wrong but the remote controller works properly. It is only in this configuration that all of the LEDs light up on the switch machine and controller.
I may delete those 2 switches in the AIU and move the wiring and add them back in. What a frustrating day.
