sACN → Art-Net Bridge
A tiny, free tool that takes lighting data coming in as sACN (E1.31) and re-sends it as Art-Net — so software that struggles with multi-universe Art-Net can drive your nodes properly.
Pure sockets — no Npcap, no Wireshark, no drivers. Just run it.

Detect your sACN, scan your nodes, map them, hit Start — the whole thing on one screen.
Some lighting software handles one Art-Net universe fine but gets flaky with several — yet its sACN output works perfectly. Since both are just "DMX over the network", this app quietly translates one into the other. Point the awkward universes at sACN, and the Bridge sends them to your Art-Net nodes. (If you found this from the FreeStyler forum — yes, this is the fix for its second-universe Art-Net.)
Everything it does
Detect sACN in
Listens on your network and lists the incoming sACN universes — click one to map it. No guessing universe numbers.
Scan for nodes
Finds your Art-Net nodes automatically (ArtPoll) and fills in their IP and Net/Sub/Uni for you.
Unlimited mappings
Map as many sACN → Art-Net universes as you like, each to its own node — unicast or broadcast per row.
Handles oddball hardware
Node addressed as Net / Sub / Uni just like its own menu, and a per-node port for the cheap ones that ignore 6454.
Live monitoring
Per-mapping forwarded-packet counters so you can see, at a glance, that data is actually flowing.
Light & portable
One self-contained exe, no install, no dependencies, no config files to hand-edit. Settings just save.
Up and running in under a minute
- 1Set your software to output sACN for the universes you want to bridge (E1.31, any universe).
- 2Detect & Scan. Hit Detect sACN in to grab the incoming universes, and Scan for nodes to grab your Art-Net gear.
- 3Press Start. The forwarded-packet counters climb and your nodes light up. That's it.
Download
Free, for Windows. Version 1.0.0.
It's an unsigned indie app, so Windows SmartScreen may say "Windows protected your PC" the first time — click More info → Run anyway. It's safe; code-signing is on the to-do list.
