These DMX Adapters from GAMMA allow you to send up to (4) universes of DMX or (4) lines of audio signal over Cat5 cable. Adapter set has 3 pin plugs for audio or DMX.
What it doesn't do: This is a point-to-point adapter, you need a set of the XLR M and the XLR F for these to work. They do NOT get connected to network switches or any other networking equipment, and they do NOT allow you to transmit Art-Net or sACN from a PC.
They are simply a very handy adapter set to run 4 lines down an existing CAT5e or greater line that is not on a network.
Many brands make these, and the only caveat is that the shield/ground is shared between all (4) channels of the wire. You MUST use shielded CAT cable, and the RJ45 plug on these adapters is compatible with Ethercon or standard RJ45 connectors.
