Abstract
A system includes a master controller disposed on a transit vehicle, a peripheral device disposed on the transit vehicle, a first wireless subsystem communicably coupled to the master controller, and a second wireless subsystem communicably coupled to the peripheral device. The master controller is operable to send a signal to the peripheral device via the first wireless subsystem, the signal comprising a command related to operation of the peripheral device. The peripheral device is operable to receive the signal via the second wireless subsystem and execute the command. The system utilizes a wireless protocol that specifies a unique identification for the system. The master controller and the peripheral device are each configured via the wireless protocol. The configuration includes storage of the unique identification and operability to restrict wireless communication to wireless communication with other devices so configured.
