Increasingly, data communication in today's lighting technology is based on the Ethernet standard. However, most older equipment and virtually all end devices continue to have DMX512 interfaces. The E-Gate family from Transtechnik allows such equipment to be incorporated seamlessly into an Ethernet infrastructure and still be used in the same way as before. Compared with traditional Ethernet converters, the E-Gate pro, plus and max offer considerably enhanced performance. The variety of ways of combining the input signals is virtually unlimited; the data from up to five signal sources (DMX, Ethernet and analog) can be used as DMX output values or as filter criteria.
