You can drive the pixel engine on the B eye separately from the “basic engine”. So you can go direct from computer to fixture using Artnet (Ethernet) cable. They don’t have artnet loop out, so you’ll probably need one or more network switches if you’ve got multiple B Eyes.
This assumes you’re driving the “basic engine” (pan, tilt, dimmer etc) via standard DMX. If you’re already using Artnet for this you’ve got a bigger challenge!
