Telemetry system for distributed equipment controls and equipment

Abstract

A telemetry system for a plurality of distributed equipment controls and/or equipment monitors that does not require complex masses of wires. The telemetry system includes an output channel for communicating control signals to the equipment controls and/or an input channel for communicating monitored signals from the equipment monitors. The output channel includes a first block of transmitter register stages for receiving a set of control signals from a controller; and a second block of distributed, series-connected parallel-output control register stages connected in series with the first block for receiving the control signals in series from the first block, and respectively positioned at the equipment controls for connection to the equipment controls for providing the control signals to the equipment controls. The input channel includes a third block of distributed series-connected parallel-input monitor register stages respectively positioned at the equipment monitors for connection to the equipment monitors for receiving a set of monitored signals from the equipment monitors; and a fourth block of receiver register stages connected in series with the third block for receiving the monitored signals in series from the third block. Signal transfer to the intended register stages is solely in response to a clock signal consisting of a series of clock pulses and a frame pulse for defining each frame of the clock signal.
