Unfortunately, when you use different DCC systems, and different decoders, not all questions are simple.
I see you have posted 6 times, all of them fundamental DCC questions. That's ok, you are clearly learning.
You might want to concentrate on either the MTS system or the Dimax system first, since you also seem to have several different locos with different decoders.
Also, have the manuals been of any help to you?
