What is the difference between Art-Net and sACN?
Quick answer
Art-Net and sACN are both Ethernet-based protocols for controlling lighting and show equipment, but sACN (E1.31) is an ANSI standard with more efficient data handling and multicast support, while Art-Net is a proprietary protocol that uses unicast and has broader device compatibility.
Art-Net, developed by Artistic Licence, is a widely adopted proprietary protocol that transmits DMX512 data over Ethernet. It uses UDP/IP and typically operates via unicast, sending data to specific IP addresses. Art-Net can handle up to 32,768 universes and is supported by a vast range of lighting consoles and fixtures, making it a de facto standard in many installations.
sACN (Streaming ACN, or E1.31) is an ANSI-standard protocol defined by PLASA. It also uses UDP/IP but employs multicast, allowing multiple devices to receive the same data stream without overloading the network. sACN is more efficient for large systems, supports up to 63,999 universes, and includes features like priority levels and synchronization. It is designed for interoperability and is increasingly adopted in professional environments.
For audio professionals integrating lighting control, the choice depends on existing infrastructure and scale. Art-Net is often preferred for legacy systems and smaller setups, while sACN is better for large, complex networks requiring efficient multicast distribution. SSOUNDS systems can integrate with both protocols via networked control interfaces, ensuring seamless show control.
Key things to consider
- Art-Net is proprietary; sACN is an ANSI standard (E1.31).
- Art-Net uses unicast; sACN uses multicast for efficient data distribution.
- sACN supports up to 63,999 universes; Art-Net supports up to 32,768.
- sACN includes priority and synchronization features; Art-Net is simpler.
- Both can be used with SSOUNDS systems for integrated control.
