Protocols it speaks

Protocol	Direction	Notes
art-net	in	Primary function: real-time monitor of Art-Net nets/subnets/universes/nodes.
dmx512	in	Displays current DMX channel values and channel history as carried inside Art-Net packets.

What to watch for

Windows only (Vista through 11); no macOS or Linux build.

Does not monitor sACN/E1.31 — the same developer's separate 'sACNominator' tool is needed for that protocol.

Typical use

Spot-check which Art-Net nodes and universes are actually broadcasting on a network
Watch live DMX channel values coming from a specific universe during rig troubleshooting
