ABSTRACT:
A signal transmission system for interconnecting a plural number of input/output devices comprises a pair of signal lines for transmitting signals between the input/output devices and a reference signal generator connected to the signal lines for generating a reference signal for using the signal lines on a time-division basis in order for each of the input/output devices to perform signal transmission during an allotted time. A reference signal detector detects the reference signal transmitted from the reference signal generator by the signal lines. A signal line using time selector selects the using time of the signal lines allotted to each of the input/output devices on the basis of the reference signal as detected by the detector and a further selector is responsive to the using time selected by the using time selector for selecting a signal transmitted by the signal lines from each of the input/output devices to others of the input/output devices and a signal to be transmitted to each of the input/output devices from others of the input/output devices.
