Having a problem that has been going on for a long time now. We have a Strand system with an ETC Ion board. The moving lights will not receive a DMX signal unless we plug them directly in to the board through DMX. The theatre is set up so that the Intelligent lights use DMX to a Strand network Node to Cat5 then on to the network. It will not receive a signal from the board through the network node but works great through a direct DMX512 directly into the board. The DMX is not an option as there are no DMX ports on the cats. ETC ION< CAT5>Wall pocket LAN>CAT 5 power supply>COM 3>CAT 5>Strand network Node>DMX512>High End Studio Spot 250. The board uses also uses a DMX512 out to the dimmers for the standard lights. Do i need to select something in the board or is it most likley a network issue. (Please say board... LAN is built in to building Please help I called strand, ETC, and High End and none of them have found a solution.
