What's so different about your other installations, other than this one won't connect to a motor? No reason why your MRC wouldn't work with a Digitrax decoder, especailly as you have others and they work fine. That's the beauty of DCC, all decoders work with all systems. I don't run ANY Digitrax decoders on my Digitrax system - don't like them.

I'm feeling a little rusty with my DCC recall and MRC was my least used system when I operated on layouts, but I don't see why you can't give it the same address and control it the way you suggest. Of course, if your E7 consist starts smoking, well...I did I meantion I was a little rusty?
