A Node must respond to an ArtPoll with an ArtPollReply within 3 seconds. If the Controller does not receive a response in this time it should consider the Node to have disconnected. It is a requirement of Art-Net that all controllers broadcast an ArtPoll every 2.5 to 3 seconds. This ensures that any network devices can easily detect a disconnect.
In order to make a product visible in DMX-Workshop, the product must reply to an ArtPoll with one or more ArtPollReply. The screenshot below shows a Wire Shark capture of the ArtPollReply packets from a Data-Lynx IOP.
Common errors in formatting ArtPollReply are:
1) The text signature at the top of the packet is “Art-Net”. It is case sensitive.
2) DMX-Workshop only listens on Port 6454 (decimal).
If you have difficulty making your product visible in DMX-Workshop then submit a Wire Shark capture on a support ticket and we will try to help.
