ABSTRACT:
An accessory decoder for a stationary switch machine is provided. The decoder comprises a printed circuit board including a plurality of input and output connectors in communication with a microcontroller. The microcontroller includes software that allows a user to designate at least one primary address and multiple route addresses for the decoder. The decoder receives digital control commands and, via the microprocessor, executes the commands to alter the output of the switch machine. In operation, one or more switch machines, each connected to a decoder, are coupled to the tracks of a railway system. A user transmits commands to the decoder, controlling the overall output of the system.
