Ring transmission network for interfacing control functions between master and slave devices

摘要: A ring network is comprised of slave devices (96) (98), (100) and (102) that are interconnected on a network. The device interfaced with test/maintenance controller (120) through serial transmission line (106). the (98) (108). (110) (112) being (114). clock generated by transmitted to each node (1188) provide an asynchronous respect thereto. Each has internal synchronizing circuit (130) for operation (120). In addition, data select (121) provided determine direction bus. selects position bus transmitting unique identifier which recognized as signal therefor function its relative point from was transmitted. can transmit either receive direction.
