DM Series

The DM Series are half-duplex parallel-type and full-duplex serial-type optical data transmission devices that enable data to be transmitted quickly and reliably between an aligned pair of units over short distances. Typical uses are on automated guided vehicles (AGV), rail-guided vehicles (RGV) and overhead transports (OHT) for providing a wireless link between the vehicle and a fixed docking station. Special models equipped with a 25-pin D-sub connector provide SEMI E84 compliance for interfacing between semiconductor process equipment and automated material handling systems (AMHS). Through a pulse-modulated light beam these transceivers can send 4, 8, 16-bit or serial signals simultaneously in both directions from the active and passive sides depending on the application requirements and model used.
