Now I'm confused as to what you have. You responded to a comment about hooking NO to "Rin". I don't see "Rin" on the diagram I copied from Atlas.
And exactly where is your "NO" signal coming from? Do you have a 153IR or MTH ITAD hooked up?
Using the diagram I copied (with DIN), you should be able to power both signals leaving both DINs disconnected. The signals should both be GREEN. You should be able to take a piece of wire and momentarily touch an outer-rail to the DIN and both signals should turn to RED. If you don't get this behavior, then using a 153IR or MTH ITAD will not change anything.
