Hi all,

This is a simple question, but I am easily confused by all the reading and video watching I am doing to get back into the hobby after 37 years.

If, as planned, I am going to use Rocrail via a Schnitte CANBUS to a MBP, and only have a MS2, and I am planning 4 to 6 routes when up and running, and assuming as I watch and read, that Rocrail controls and verifies the turnout positions for the planned route, why do my turnouts NEED a decoder on top of the motor? I mean if Rocrail substitutes me hand controlling the turnouts, why is a decoder needed?

I have to order some more tracks as I did the calculations wrong back in the day and the layout will not be even provisionally sewt up, so I am wondering if I also need to order decoders for the 4-5 switches to be managed by Rocrail.

Many tnx in advance and please take into account I have not done electronics or computing in my 70 years, so my understanding of terms and concepts is very limited.

Santiago
