Abstract
A network system having a single-wire common signal transmission line to which a plurality of data processing stations and a synchronous code signal generator are connected. Each station constituting the network system comprises: first means for repeatedly generating an address information bit signal based on a predetermined time series code for each predetermined synchronization timing, modulating each address information bit signal into a synchronous signal having predetermined pulsewidths which is dependent on a bit status of each address information bit signal and outputting the modulated synchronous signal to the common signal transmission line so as to be superposed on the serial bit data string, second means provided within each station for receiving the synchronous signal on the signal transmission line derived from the first means and extracting the bit status information of the predetermined time series code from the received synchronous signal on the basis of the pulsewidth of the received synchronous signal from the common signal transmission line, third means for determining bit combination pattern of a predetermined bit length inherent in the predetermined time series code from the predetermined time series code comprising each of the bit status information extracted by the second means, and fourth means for determining an operation mode of the station from the bit combination pattern determined by the third means.
