Abstract
An apparatus and method of communicating data signals on a bus having an upstream portion to which transmitters of a plurality of station are connected, and a downstream portion to which receivers of the stations are connected, and to which an end station is connected having a transmitter connected more upstream than any of the plurality of stations. Signals to be transmitted from each of the plurality of stations are appended to the end of the data stream passing thereby. A bus clear signal is transmitted from the end station, along the bus. When any signal including the bus clear signal is detected from upstream at any of the plurality of stations that might be transmitting, transmission of signals from the plurality of stations is immediately terminated. Transmission of the bus clear signal from upstream thus clears the bus to allow for transmission of different priority signals on the bus.
