Abstract
A multiplex transmission system according to the present invention is provided with a plurality of multiplex nodes which are connected in parallel with two common buses so that data are transmitted between the nodes. A receiver circuit of each multiplex node includes a passive potential detector section and bias sections. In case of any trouble on the buses, in this multiplex transmission system, the passive potential detector section detects the respective passive-mode potentials of the buses, controls the bias sections in accordance with the detected passive potentials, and sets input potentials within a predetermined range, thereby enabling data transmission between the multiplex nodes.
