DMX lighting will not work on FLX10 now matter what I do

FLX10, Fixture is ADJ Mega Bar RGBA, Mac Sequoia 15.1.1 

I just got the FLX10 mainly because of the integrated DMX out and I cannot get it to connect to my fixture. What I want to do is let it play the automatic light show based on the analysis. A little new to Rekordbox, came from Denon/Serato.

I downloaded Rekordbox ver. 7, is there an additional driver or anything I need for DMX? Dont feel like theres much o the internet for this feature. 

Can anyone help?
