The DMJ Series optical transceivers extend the parallel I/O communications associated with 300mm material handoff operations between active and passive equipment.  As an alternative to the standard DMS and DMG parallel I/O devices, these sensors offer an RJ-11 connection between the sensor heads and DB25 connector modules.  This allows for greater flexibility with installing the transceivers, while retaining compatibility with the parallel interface.  With a built-in data logging feature, the transmission/reception signals can be captured and recorded in an expanded non-volatile memory.
