In the decoder controller, P/MV outputs can be assigned to either direct terminals in the controller, or to ICD-100 station decoders.
P/MV outputs 1 through 3 refer to the output terminals on the Power Supply Board, unless they are changed to decoder locations. P/MV outputs 4, 5, and 6 must be assigned to decoders.
All P/MV outputs are set to Normally Closed operation, but they can be changed to Normally Open functions in the Devices menu. See P/MV Operation section.
