Going to help a friend this week to figure out why his crossing gates are not working and wanted to review my memory on how the MTH crossing gates and infrared detectors are to be wired. I used to have these on my layout but that was a few years ago. Here are the wiring diagrams from MTH. we do not have the track connected ITAD but the infrared version.
Here is my question. Does anyone remember if the infrared unit wiring is the same as the ITAD with white and yellow connected to NC and NO on the infrared? Seems I fooled with this in the past thinking I had to connect the common on the infrared unit to track common but that was not true. Thanks in advance for input.
