  • Ring transmission network for interfacing control functions between master and slave devices
    Patent number: 4615029
    Abstract: A ring network is comprised of slave devices (96) (98), (100) and (102) that are interconnected on a ring network. The slave device (96) is interfaced with a test/maintenance controller (120) through a serial transmission line (106). The slave device (96) is interfaced with the slave device (98) through a serial transmission line (108). The slave device (98) is interfaced with the slave device (100) through a line (110) and the slave device (102) is interfaced with the slave device (100) through a line (112) with the slave device (102) being interfaced with the controller (120) through a line (114). A clock is generated by the controller (120) and transmitted to each of the slave devices through a node (1188) to provide an asynchronous clock with respect thereto. Each of the slave devices has an internal synchronizing circuit (130) for synchronizing the internal operation of the devices with respect to the controller (120).
