Sorry for a simplistic topic that many already know well.
I am in N and use the Prodigy Advance, which has quick sets Start Voltage, Acceleration, Deceleration and Top Voltage without CV's.
I have read many of the DCC books, and last night, one seems to say that the settings are relative to or a percentage of the top voltage.
In any event, if anyone can explain the basics, typical settings for each in N, I would appreciate it.
