Art-Net setup

Art-Net carries DMX universes over IP (UDP, port 6454). It’s a practical way to push a lot of pixels from a media server or console without running wired DMX, and on OmnaDMX it goes both ways, with input and output independent.

Receiving Art-Net

Get the controller on the network first. Wired Ethernet on the S3-ETH is the reliable choice for show traffic; WiFi is fine for lighter loads. Then set the input source to Art-Net in the DMX tab and patch the device’s universe(s) to match your sender.

Art-Net addresses a universe as Net / Subnet / Universe — a 15-bit port-address. Match all three, not just the universe number. A frequent mistake is lining up “universe 1” while Net or Subnet differ, so nothing arrives. The device takes broadcast or unicast Art-Net; on a busy network, prefer unicast (the sender targets the device IP) so you’re not flooding every node.

For per-pixel control across several universes, use DMX Pixels mode and Multi-universe addressing.

Discovery (ArtPoll)

The device answers ArtPoll, so controllers that scan the network see it by its device name, with its input/output role and active universes. No manual node entry on pollers that support discovery. Give it a recognisable device name so it’s easy to pick out in a rig.

Sending Art-Net out

Independently of the input source, set the output type to Art-Net (System tab) to stream the rendered pixels back out, for feeding other nodes, recording, or chaining devices. Per-strip destination IP and universe mapping live on the Strips tab. The UI flags two specific mistakes: a universe overlap, where two output strips share a universe range, and input/output feedback, where the same universe is used for both directions and loops.

Note

Art-Net on either input or output is one of the things that holds the on-demand network link up. Switch both away from network and the link is free to drop again — that’s expected idle behaviour, not a fault.
