Hi - I am trying to automate a Bachmann EZ Track switch using an MTH DCS Commnader, TIU, and the AIU using the AIU to manage my switches The EZ track switch has a three wire coming off the track with a plug connector. I cut off the connector and soldered the three wires onto another set to extend and denote. I have the middle wire which I thought was common wired as yellow, the right and left as red and green. I wired the AIU switch with Yellow as the ground and red as input 1 and green input 2. I then used the DCS Commander, selected the switch and then using the soft keys attempted to initiate the switch, Nothing happens - I've switched the wires around to oher configurations. But still no success. Can you tell me how ro wire the switch so I can invoke from the Commander ?
Thanks - Doug Palmeri
