ABSTRACT:
A system for transferring data between a plurality of devices is disclosed. Each of the devices is connected to a communication bus by a corresponding control unit. The communication bus comprises a data signal path and a control signal path. Each control unit may transmit data to all of the other control units upon reception of a control signal which is generated by that control unit which is positioned at a "head-end" of the bus. The control signal also serves to indicate the direction of travel of data signals on the data signal path.
