I have a DR5000 with 2 DR5033 running 2 regions and the DR5000 running DCC accessories such as my DCC concepts Digital IP point motors - which I believe are pretty much like a tortoise but with a DCC interface fitted.? The resulting frog power comes from the accessory bus.? The auto polarity is switched off on the DR5033s
I have 4 reverse loops and I use a design from Rudys Model railway to manage them.? It's cheap, uses widely available components and you don't have to be an electronics wizard or script programmer to install it.? Above all, I have found it rock solid reliable!
Whilst it's not a direct solution for you I think it could be of interest.?
Best of luck,
Adam
