Many guides seem to try to make you believe that Artnet is required to use your uDMX interface, which is not true. What is it, and do you actually need it?īefore we talk about what Artnet is, does someone using uDMX actually need to run it? Simple answer – no. If you are currently setting up your uDMX interface, you may not know what Artnet is, but your installation guide may ask you to run it. If you are a uDMX user, you will almost definitely have heard of Artnet.
