ABSTRACT:
A high-speed two-way optical data link has both light-emitting and light-sensing units mounted adjacent one another in a single housing together with a timing and control unit providing all signals necessary for simultaneous transmissions and reception of data. Synchronization to a clock signal is achieved by use of edge detectors which reset to zero counters in the timing and control unit whenever a transition in data pulses is sensed. A pair of computers are linked using a program called "Crosstalk" which performs full parity checking of all data received by an associated computer. Both computers are live handshaking and asynchronous at all times.
