How to use DMX Display Cluster Plugin?

Hi
Does anybody already used the DMX Display Cluster Plugin?
What it’s for and how to use it?

I do not find anything in the current UE5 documentation. I assume it is used to sync DMX messages in a nDisplay cluster. In the source code, I see that I have to add -dc_dmx_primary as command line argument to mark the primary node. I did that but I don’t know what else I need to setup.

My use case is, that I want to receive DMX from external light console to trigger Lights in the level in a nDisplay environment with multiple render nodes (nDisplay nodes). If i just process DMX messages on every node unsynced, i can see latency on the LED wall between the clusters. So DMX has to be synced between the nodes.

Or is there any other workaround for that problem?

Thanks for any advice.
