Abstract: A control system for selectively communicating a plurality of sensors with associated remote control devices includes a Master Synchronizer, a transmitter for each sensor and a receiver for each control device. A single signal line is connected to all transmitters and receivers, and a single synchronization line couples the Master Synchronizer to all transmitters and receivers. The Master Synchronizer generates a time frame signal which has a reset portion for resetting all transmitters and receivers synchronously at the start of each frame, and a periodic portion which determines the time slots for each frame and which decrements counters in all transmitters and receivers synchronously. A time division multiplex system is used to communicate each transmitter with one or more associated receivers during a predetermined time slot of a periodic time frame determined by the Master Synchronizer.
