(asked at Electrical Engineering but not on topic there)

We have to expand a DMX512 installation and it looks like Artnet would be a good fit. We'll be using a commercial Artnet -> DMX (or -> SPI) receiver that implements Artnet 4.

This a very simple, self-contained installation with just two devices, a controller (we build) and the decoder. We'll generate the Artnet data locally, using a micro or a PC. We have the protocol in hand, and DMX experience.

Question is, do we need to implement the entire Artnet poll/reply, auto-IP etc or can we just assign fixed addresses and start shipping Artnet packets down the wire to the assigned UDP port?

  • @DanielA.White - and yet there are several Qs here about Artnet that have not been closed. Is there a better forum for this? – Jim Mack Aug 30 '23 at 13:42
  • I’m not sure of one – Daniel A. White Aug 30 '23 at 13:43
  • Apparently there's no home in the Stacks for this question, or this topic. Odd because there are both **dmx512** and **artnet** tags in use here. – Jim Mack Aug 30 '23 at 16:37
  • A tags existence doesn’t mean a question is on topic here. There are programming related questions about dmx and art net. Your question reads more of a networking question which is off topic. – Daniel A. White Aug 30 '23 at 16:49
  • It does feel like a programming question. Do we need to program the entire suite of Artnet master functions or can we act as a sender if we just fill in the structure and send it? The protocol spec doesn't say anything about it, AFAICT. But if the Q isn't well received here, so be it. – Jim Mack Aug 30 '23 at 19:16
