It could also be that those lights are not following the DMX Standard and flickering because of RDM.
You will need to use our Concert Software which can be downloaded for free from our website and you can change the DMX speed on that port to slow.
If that doesn‘t help, then disable RDM on that port. If the flashing stops then when RDM is disabled, please contact the manufacturer of those lights and let them know that their DMX lights don‘t follow the DMX Standard, and ask if they plan on fixing this for you.
