If you connect the MTH ITAD 'NO' terminal to the Atlas signal DIN#1 the signal works like you want (Turns red, but after a while goes yellow then green.), correct? If so place one ITAD and signal at each end of the stretch you want the signals to be and wire them up like that. Now to tie them together so they trigger at the same time run one wire from the 'NO' terminal of the ITAD at one end to the 'NO' terminal of the ITAD at the other end. In this way you are basically giving each signal the same dual trigger.
Do not run any wires between the Atlas signals. You only run wires between the Atlas signals if you want one to control the other for sequential signaling, which is not what you want.
If you connect like you suggest, with out tying the two ITAD's together via the NO connection each signal will operate correctly, but will be totally independent. If you now connect the two ITAD's together via the NO connection you are also connecting the two Atlas DIN connections together since they connect to the NO connection. Once the two DIN connections are tied together both signals turn red and stay that way and do "NOT" turn back to yellow or green.
Then something is not set up correctly, or is wrong with the control boards. I can not think of any reason for that behavior of your signals.
I have two atlas signals. Both work perfectly if each is connected to it’s own iTad, or two separate isolated blocks. I therefore would normally assume that there is no problem with either signal. Now let’s take the itads and isolated blocks out of the equation. With only power going to each signal control board, and the signal plugged into its rj45 connection, and only one wire coming out of the din connection of each signal control board, try the following. Touch the ends of the two din connected wires together. In my case both signals go from green to red and stay that way. So based on that exercise, connecting them to the same block would only have the same result since the rail is nothing more that a extended connection to the two din wires.
