Lou, thanks. I'm definitely going to read the PDF. Just downloaded it. I wanted to be sure what I want to do is feasible, and it sounds like it is. I know my brother-in-law runs TMCC 1.0 and DCS, but he has a Z4000 transformer. I just didn't have the heart to get rid of my grandpa's old PW transformers. I still think of him when I turn them on.
All of my transformers are in phase. No worries there. I learned about that 2 layouts ago, but thanks for keeping me in check.
I think I'll go fixed and leave the powermasters in place which I presume means I can only run conventional with my CAB-1 but that's OK. I have two CAB-1s, so no big deal with the DCS remote sits on conventional days.
So, it sounds like with one TIU, I use DCS on all of the loops/blocks my TMCC command base, right?
Guess I'll to read up on why there are 2 variable and 2 fixed inputs and 2 variable and 2 fixed outputs. ****, 145 pages is a lot of reading!
Thanks everyone. Just trying to keep this successful. I've been reasonably successful with TMCC and don't want to do a wholesale change to DCS (even if it's better, no time for the effort). Too much invested in TMCC.
