I am trying to wire up two Ross Switches for non-derailing. I am using DZ-1000 switch machines. I have read every prior post I can find on the forum, which has given me a few ideas that I plan on trying to see if any of them correct the issue (Non-derailing is not working at all). But my question revolves around the use of the MTH AIU. Is there anything specific I need to do regarding the wiring since the switch is wired through the AIU. Also, I do not use the DZ 1002 switch buttons, so the wiring goes directly from the AIU, and terminal block, to the switch machine.
