Our Atlas O and Ross switches we connected to our AIU. For some reason the AIU itself just clicks. I pressed read and it shows the TIU and the 2 AIU's. Only 1 AIU is being used. The remote show all kinds addresses. I added a new switch address and just the AIU just clicks.

Did you follow the wiring diagram for this?

I found on an old O Gauge Forum 11/05/15, Ed Walsh. Help diagnosing AIU Switch problem. In which I will try today. I'am using MTH 24 Port Terminal Block. Soldered Wire Terminals to the block. I even tried direct to the Z4000 transformer. A question on Stan's suggestion, The Common wire is from the Block to the AIU IN and you briefly touch Port 1 and Port 2 by 1 wire from the switch, "Correct"?
Has anybody had problems with AIU's in series? My 2 AIU's at home work just fine. Plugging 2nd AIU to AIU1 should not just click?
