sACN Sender sample

Using the sACN sender sample bundle

The sacn-sender example bundle in samples/sacn-sender demonstrates the ability send data via sACN to e.g., open lighting architecture or professional lighting equipment. Here is a guide to how to get it working.


You will need a working nodecg-io installation. If you have non yet take a look at installation guide. You may need to install this bundle, so take a look at the “Try an included sample”-Guide. It will also tell you how to log in and how to use the GUI.

You also need:

  • A working sACN receiver in the current network

Configure the sACN sample bundle

  1. In NodeCG, create a new sacn-sender service instance.
  2. Enter the needed options:


    The universes to use. Must be an array with numbers within 1-63999

        "universe": 1


    Optional. The multicast port to use. All professional consoles broadcast to the default port 5568.

        "universes": 1,
        "port": 5568

    ReuseAddr Optional. Allow multiple programs on your computer to listen to the same sACN universe.

        "universes": 1,
        "reuseAddr": true

    After entering them, click save.

  3. Set the sample's (sacn-sender) dependency to be the newly created service instance (of type sacn-sender).

  4. Check the NodeCG logs:

    You should see data logged.
