Auxiliary registers exist for DCC systems that can only program CVs from 1-255

An audio frequency filter is integrated within the main locomotive PCB to ensure each speaker reproduces within it’s ideal frequency range

Late EE cantrail grilles

The outputs are +5v/0v so you can use these switches to drive computer or DCC control at the same time

HF-1 High Frequency Electronic Track Cleaner - Single Track Scale_OO9-Scale all to the design ofThe 12v DC controlled output from the controller is passed through the unit. Connection between unit, power source, controller and track is achieved via six terminal connections. The unit superimposes a harmless high frequency signal over the output from the controller. When a poor contact between locomotive and rail is detected, the unit switches on, ionising the gap and burning off the dirt, switching off again when contact is restored. Compatible
