DMX Compander makes it possible to run three DMX512 Universes in one CAT-5 cable. A CAT-5 cable has four data-pairs, one pair is used as the 0V reference and the other three pairs are used for DMX512 Data+ and Data-. Through the three RJ45 connectors, three DMX512 Universes are “COMpressed” into one CAT-5 cable via the ‘Universe 1+2+3’ RJ45 connector. On the other end of the CAT-5 cable another DMXcompander is used to “exPAND” the DMX512 Universes again, making them available through the three RJ45 connectors. Together with CPOINT’s XLRJ45 adapters (see related products tab below), a DMX512 network can be set up very quickly and at a very low cost.
