<p>An improved peripheral station in an information handling system of the type having a signal bus, a master station and a plurality of peripheral stations controlled by signals transmitted on the signal bus by the master station. Information is transmitted cyclically in information frames and each peripheral station responds to one of these frames. The peripheral station includes an address decoder for identifying the information frame to which the peripheral station responds, a gate circuit for coupling signals from the signal bus to one or more outputs of the peripheral station, circuitry for verifying the gated signal by comparing it with a corresponding next-received signal, and a synchronization detector for maintaining synchronization of the signals transmitted from the master station to the peripheral station.</p> |
