Streaming ACN Sender

This module will transmit SACN packets to the IP and universe you specify below. If you need more universes, add multiple SACN instances.

Functions and Configuration Options

• Source Name
  Sets the name that will be broadcast as the sACN source. This is visible to receivers.

• Source UUID
  Unique identifier for this sACN source. Should be unique for each instance.

• Receiver IP or Multicast IP
  The destination address for sACN packets.

  • For unicast, enter the IP address of a single receiver (e.g., 192.168.1.101).
  • For multicast, enter a valid sACN multicast address (e.g., 239.255.XXX.XXX).

• Bind to specific IP (optional)
  The local network interface IP address to send packets from. Leave blank to use the system default as shown in $(internal:bind_ip).

• Universe (1-63999)
  The sACN universe number to transmit. Each instance can send to a different universe.

• Priority (1-201)
  Sets the DMX priority for this source. Higher values take precedence if multiple sources are present.

• Update interval when no fades are running (ms)
  How often to send sACN packets when idle (default: 1000ms or 1 Hz).

• Update interval for fades (ms)
  How often to send sACN packets when a fade is running (default: 40ms or 25 Hz).

• Variables to expose, channel range
  Specify which DMX channels (slots) to expose as variables in Companion.
  Example: 1-5,34,100-130 exposes channels 1 to 5, 34, and 100 to 130.

Unicast vs Multicast

• Unicast
  Enter the IP address of a single receiver. Only that device will receive the sACN data.

• Multicast
  Enter a multicast address in the range 239.255.0.0 to 239.255.255.255.
  All devices listening to that multicast group and universe will receive the data.

  Examples

  • For Universe 1: 239.255.0.1
  • For Universe 10: 239.255.0.10
  • For Universe 256: 239.255.1.0
  • For Universe 513: 239.255.2.1

Notes

• If you want to send to multiple universes, create multiple module instances, each with its own universe and (optionally) multicast address.
• Make sure your network and receivers support multicast if you use it.
• The "Variables to expose" setting allows you to limit which DMX channels are available as variables for triggers or feedback in Companion.
