Abstract
There is disclosed a multiplex communication method of transferring data between a plurality of nodes via a single signal line in a time sharing manner. The data transmitted from each of the nodes includes a start bit, data bits and a parity bit in a serial order. The data is associated with and interposed between a start signal and a stop signal. Each of the start bit, data bits and parity bit is composed of a forward half portion representing data contents and a rearward half portion representing a gap. Signal levels of the forward and rearward half portions of each bit are in inverted relation to each other. It is determining whether the signal levels of the forward and rearward portions of each bit of the data recieved by each of said nodes are in inverted relation to each other, thereby deciding that the received data is correct if such inverted relation is detected.
