Chauvet DJ- DMX-AN2 nomad setup

I'm not familiar with the Chauvet product, but you could download sACNView (https://sacnview.org/) to use to see if you are outputting sACN data OK, or to use to output some test data.

Assuming that is ok, it sounds like the DMX-AN2 has a web page, I would browse to it (type the IP in your computers web browser) and see if it has any diagnostic info, or if you need to enable sACN on it.

Very new to Nomad and having similar problems here. Running Nomad on a Mac and trying to connect to ArtNet Network. ETC 'tip' appears to suggest I need to load Net3 Gateway Configuration Editor. But this is a Windows program so it won't load. Any advice. Thanks.

Instead NGE which is deprecated use Concert, this software works also on macOS. www.etcconnect.com/.../Concert.aspx
For ArtNet there is an ArtNet viewer on https://artnetview.com

Thanks for the advice. In the end it appears the problem was me programming the network node to universe 1 when with the ArtNet it shoiuld have been universe 0. All seems fine now.
