ABSTRACT:
A current mode data or power bus which provides communication between two or more terminal devices over a common, single-channel medium. The data bus comprises a pair of wires, twisted to form a succession of loops and short-circuited at both ends, together with an arbitrary number of bus couplers, one for each terminal. The bus couplers are formed by separate, disengageable core elements. Each bus coupler is inductively coupled to the twisted wire pair by inserting one or more core legs of the bus coupler through adjacent loops in the twisted wire pair; each wire loop around a core leg then constituting a one-turn transformer winding of the coupler. In this manner, separate terminals can be readily coupled to or decoupled from the current mode data communication bus without the need for making spliced, galvanic connections. This bus configuration is readily adaptable to single or multiphase power transmission. And, in either case, the bus configuration provides excellent electromagnetic interference rejection properties.
