DMX vs Art-Net vs sACN: Which Protocol Should You Use in 2026?

The Three Lighting Protocols

If you're setting up automated lighting for DJ events, you'll encounter three protocols: DMX512, Art-Net, and sACN (E1.31). Each has different strengths, and the right choice depends on your setup.

DMX512 — The Original

DMX512 is the granddaddy of lighting control. It's a serial protocol that runs over 5-pin XLR cables.

Pros: Universal support, simple cabling, proven reliability Cons: Limited to 512 channels per universe, requires physical cables, no networking

Best for: Small setups with fewer than ~30 fixtures in a single chain.

Art-Net — DMX Over IP

Art-Net sends DMX data over standard Ethernet networks. Multiple universes on one cable.

Pros: Multi-universe over Ethernet, widely supported, GrandMA native Cons: Uses broadcast/unicast UDP, can congest busy networks

Best for: Professional setups with multiple universes and GrandMA consoles.

sACN (E1.31) — The Modern Standard

sACN is the ANSI standard for streaming DMX data over IP. Uses multicast for efficient delivery.

Pros: Multicast (efficient), standards-based, priority levels for merging Cons: Slightly less universal than Art-Net in older equipment

Best for: Large-scale installations, touring rigs, and setups where multiple controllers need to merge.

Which Should You Use?

Using All Three with CueSync

CueSync includes Art-Net and sACN DMX-over-IP output in every edition — including the DJ Edition. You can add as many outputs as your rig needs, so if one node expects Art-Net and your LED wall processor uses sACN, add one of each under Network → Outputs and pin each DMX action to the output it belongs to.

No edition caps the number of Art-Net or sACN universes — universe count is not a licence question.

Download CueSync free and run the demo show and tour the app in read-only mode; with a subscription, add your outputs under Network → Outputs (⌘9). See also: automating lighting with grandMA3, the Art-Net + sACN integration page, and pricing.
