Abstract
An improved telemetry system for transferring data signals to and from a plurality of serially-connected, addressable data ports. The telemetry system includes a plurality of serially-connected input/output (I/O) data ports; an output data line and an input data line serially-connecting the data ports; a clock signal generator for generating clock pulses and frame pulses for common system timing; and a clock line for carrying the clock pulses and frame pulses from the clock signal generator to the ports. Each data port contains an address circuit which determines when during each frame that port is enabled to transfer data an input shift register for loading data signals for transfer onto the input data line at a time indicated by a transfer signal provided by the address circuit; and an output shift register for temporarily storing output data signals received from the output data line immediately prior to the provision of the transfer signal by the address circuit.
