More Information
Summary:This invention relates to a novel two-wire, two-way optically insulated communication technique for minimizing hardware and wiring of a data communication system. A control station (20) is in data communication with a plurality of remote stations (22-1, 22-2, ... 22-n). Each remote station includes a receiving opto-isolator device (26) and a transmitting opto-isolator device (28), each having an LED and an associated light detector. The LED (40) of the receiving opto-isolator is in series circuit arrangement with the detector (46) of the transmitting opto-isolator. A plurality of remote stations are provided either in series or parallel circuit configuration. If in series configuration, a bypass circuit (90) may be provided in the event of a failure of a particular remote station.
