The two-way communication is what enables advanced features like transponding (knowing which loco is where), real-time slot status, and CV read-back from anywhere on the system.About Digitrax: Digitrax is North America's leading manufacturer of DCC systems and has been the architect of the DCC standard since the 1990s. The proprietary LocoNet control bus is the most widely-supported throttle and accessory interface in club layouts worldwide, and Digitrax decoders / boosters / command stations are fully NMRA DCC compliant and interoperable with all NMRA-compliant DCC equipment.In stock at Oakville Model Trains Depot.
