Abstract

PURPOSE:To reduce transmission lines in number, and also to simplify an interface device and other circuits as to a system which performs mutual data transmission between a controller and several controlled units controlled by it. CONSTITUTION:A wired-OR connection is made between controller 2a and controlled units 2b to 2x controlled by controller 2a, and solid wire bus 1. Then, normally-synchronous pulse signal A is sent out to bus 1 by controller 2d, and data transmitting signal C obtained by pulse-width-modulating signal A by digital data signal B is sent out to bus 1 by controller 2a and control units 2a to 2d. This signal C is made into a series one-word signal composed of a start bit signal and several data bit signals and after a series of signals C are transferred to bus 1 from controller 2a and any one of control units 2a to 2d, controller 2a sends out an end word signal composed of end bit signals to bus 1.
