ABSTRACT:
A system for controlling signal transfer between a plurality of devices, for controlling the transfer of signals between a main device having processors packaged therein and a subsidiary device having units packaged therein, includes a multiplexer section on the main device side for multiplexing signals from a control system processor and a monitor system processor of the main device; a demultiplexer section on a subsidiary side for demultiplexing the multiplex signal from the multiplexer section on the main device side and distributing it to the units of the subsidiary device; a multiplexer section on the subsidiary device side for multiplexing the signals from the units of the subsidiary device; and a demultiplexer section on the main device side for demultiplexing the multiplex signal from the multiplexer section on the subsidiary device side and distributing it to the control system processor and the monitor system processor. The multiplexer section on the main device side executes bit-stuffing and multiplexing in such a manner as to correspond to the phase or frequency difference between clock signals from clock generators and transfers the signal to the subsidiary device through a cable.
