ABSTRACT:
A current mode data communication system is disclosed in which the system data bus is formed by an unshielded twisted wire pair (12). Coupled to the data bus by bus couplers (16) and bus-to-stub couplers (80) are current mode data stubs (82), which also are formed by pairs of twisted, unshielded wires (84 and 86). One or more interface-to-stub couplers (88) are inductively coupled to each curretn mode data stub and, in addition, are connected in signal communication with one of the system utilization devices (10). Data signals propagating along the system data bus (12) are coupled to each utilization device (10) via an associated bus coupler (16), bus-to-stub coupler (80), and interface-to-stub coupler (88) without reflecting the signal into the system data bus (12). Signals are supplied to the system data bus (12) by each utilization device (10) via an associated interface-to-stub coupler (88), current mode data stub (82), bus-to-stub couple (80) and bus coupler (16) without direct coupling of the signal to either the receive channel of the utilization device (10) that is transmitting signals to the system data bus (12) or the receive channels of other utilizaiton devices (10) that utilize the same current mode data stub.
