Light Bytes – Inside Art-Net & sACN is a concise technical reference by Wayne Howell, inventor of Art-Net. Written for engineers, it opens with a clear networking primer, then details packet structures and definitions for Art-Net 4 and sACN (ANSI E1.31). Practical chapters cover system design trade-offs, targeted discovery to manage bandwidth, switching port direction on-the-fly, diagnostics, and common pitfalls in real-world deployments.
The second edition (August 2023) adds updated Art-Net packet descriptions, expanded developer tips, and fully refreshed guidance for tools such as DMX-Workshop, Bandwidth-Tester and Multicaster. If you’re implementing or troubleshooting DMX-over-IP at scale, the focused scope and protocol accuracy make this a useful bench-side companion.
