Do you have an interface for DMX yet?
You likely want either something Enttec compatible or something for ArtNet. Both work similar but slightly different (although you can swap the outputs once you know how these work)
My Add-on is a common starting point for Enttec interfacing, it has both a user actor and a demo file: TROIKATRONIX : ISADORA - DX – DMX Universe – Enttec compatible
