- Sending and receiving data using the ANSI E1.31-2018 protocol over IPv4 and IPv6
- Unicast, Multicast and Broadcast Supported
- Tested on Windows and Linux
- Universe Synchronisation
- Universe Discovery
cargo run --example sine-wave-sender
Compliance with the ANSI E1.31-2018 protocol was tested (April 2020) and the results are shown in 'documentation/ANSI-E1.31-2018-Compliance-Check-List.pdf'.
ESTA 1.31-2018, also known as ANSI E1.31-2018, defines how to transmit DMX512 lighting control data over standard Ethernet networks using the sACN (Streaming Architecture for Control Networks) protocol.
It is widely used in theatrical, concert, architectural, and broadcast lighting environments.
- DMX512: A digital control protocol used to manage stage lighting and effects. It transmits values (0–255) for up to 512 control channels per line, called a universe.
- Universe: A group of 512 DMX channels, each corresponding to a controllable parameter like brightness or color. Large shows often use many universes to control numerous fixtures.
- Ethernet: A standard computer networking technology that allows data to be transmitted over cables like CAT5e or CAT6. In this context, it enables DMX data to travel over modern IP-based networks.
- sACN (Streaming ACN): A protocol built on IP networking that transports DMX data efficiently over Ethernet, allowing fast and reliable lighting control.
- Defines how to run the DMX512 protocol over an Ethernet-based network, using specific IP addresses and multicast to send data.
- Enables multiple senders and receivers to operate on the same network.
- Scales to large systems with many universes and devices.
- Includes rules for data merging and priority, so multiple controllers can interact with the same fixtures without conflict.
- Simplifies wiring for large or distributed lighting systems.
- Enables flexible control setups, including remote operation.
- Scales easily to support complex or high-density lighting installations.
- Widely supported and adopted in professional lighting environments.
ESTA 1.31-2018 allows high-speed lighting control data to be transmitted over regular computer networks instead of older DMX cables, making modern lighting systems more powerful, flexible, and scalable.
