Abstract

PURPOSE:To eliminate the effect of the noise and the diconection with a reduced number of the control signal lines and by combining the selection transmission lines forming a matrix when the data is transmitted between the central processor and several units of the data input/output units which are dotted on the common bus transmission line. CONSTITUTION:One of input/output units 14a 14i is selected via gate control signal transmission line 15 formed with digital output interface devices 12a and 12b. And then, for example, unit 14a is selected via lines (a) of devices 12a and 12b. The selected input/output unit performs the data transfer to processor 10 via common bus transmission line plus interface devices 11a and 11b. As the gate control signal transmission line features the matrix structure, the occurrence can be reduced for both malfunction and disconnection.
