Question about MTH

[Charlie B]

The instructions say to set CV 52 to PWM before you can set these perimeters. I did not want to enter this until I knew what it was. It most likely is Pulse Width Modulation but it would be nice if the instructions took the time to write it out. DCC is not hard but understanding instructions at times ia a real challenge. I will go ahead with it and hope there is a reset somewhere if I mess up.  More to come.
