Features
This unit together with one or more GCA108 boosters, is an ideal combination in DCC train control.
- Keyboard and display connection (GCA111).
- Can be used as stand-alone controller.
- Without GCA108, capable of controlling 1 train directly
- Loconet commanded, using buffer GCA85 or GCA101. Without GCA85 or GCA101 additional supply (12-16Vdc) and current source for LocoNet is needed.
- Programming of DCC decoders with additional small interface (under design).
- LocoNet compatible, excluding programming.
- Fred's are supported. (Not the new FredI's!)
- Standard equipped with 2 DCC outputs 0,5 A each for driving LEDs in IR systems.
