DMX Node Setup: Art-Net & sACN to DMX

Short answer: a DMX node converts network protocols (Art‑Net or sACN) into a physical DMX line. A clean IP plan and correct universe mapping are what make it stable.

What a DMX node actually does

Short answer: it receives lighting data over Ethernet and outputs DMX on 3‑pin or 5‑pin XLR.

If you need a protocol overview, see DMX protocol stack 2026.

Before you plug anything in

Short answer: decide your IP scheme and universe plan first.

• Pick Art‑Net or sACN for the network.
• Assign a subnet and IP range.
• Map universes to outputs on the node.

Step‑by‑step node setup

Short answer: configure network, assign universes, then test with one fixture.

1. Set node IP to match your controller network.
2. Select protocol (Art‑Net or sACN).
3. Assign universe(s) to each DMX output.
4. Connect DMX output to a single test fixture.
5. Confirm data flow, then expand the chain.

Common mistakes that break shows

Short answer: the most common failures are IP conflicts and universe mismatches.

• Node and console on different subnets.
• Universe numbering mismatch between console and node.
• Multicast flooding without proper switch settings.

Where the DMX cabling still matters

Short answer: the node fixes networking, but DMX cabling rules still apply.

Use proper cable, avoid passive splits, and terminate the last fixture. See DMX cable & termination field guide and DMX splitters and opto‑isolation.

Quick checklist

• IP plan defined and consistent.
• Universe mapping verified.
• Single‑fixture test passed.
• DMX line terminated and clean.
