A wireless optical interface is described for providing communication between elevator dianostic equipment and elevator control equipment. The interface comprises a first light transmitter/receiver element connected to the diagnostic equipment, and a second light transmitter/receiver element connected to the elevator control system, the first and second elements in light communication with each other. Each of the first and second light transmitter/receiver elements include a photo transistor/light emitting diole pair and associated circuitry for converting back and forth between electronic and light data formats. |
