Follow your system manufacturer’s instructions for wiring your DCC Command Bus or Network and Feedback Bus.
Digitrax LocoNet requires a 6 conductor phone wire network phone jack type outlets. These outlets can be daisy chained around the layout. This system is topologically similar to an Ethernet type computer network. LocoNet does not require a separate feedback bus.
