<p>A multiplex transmission system according to the present invention is provided with a plurality of multiplex nodes(10,20,30) which are connected in parallel with two common buses(1,2) so that data are transmitted between the nodes. A receiver circuit(13) of each multiplex node includes a passive potential detector section(16) and bias sections(17,18). In case of any trouble on the buses(1,2), in this multiplex transmission system, the passive potential detector section(16) detects the respective passive-mode potentials of the buses(1,2), controls the bias sections(17,18) in accordance with the detected passive potentials, and sets input potentials within a predetermined range, thereby enabling data transmission between the multiplex nodes(10,20,30). <IMAGE></p> |
