ABSTRACT:
A time-division multiplex (TDM) control system for controlling a plurality of devices from a central point includes a transmitter whose output is coupled over a common path to a plurality of receivers respectively located adjacent to the devices. The transmitter provides a repetitive cycle of a predetermined number of time slots during which a control signal is provided at any one or all of the time slots. Each receiver is assigned a given time slot corresponding to one of the time slots in the repetitive cycle of the transmitter, and each receiver is responsive to the control signal during its given time slot. Each receiver is operative to control one of the devices in response to the control signal.
