Hey there,
I got that weird problem with my Gadget... I am almost sure that the problem is not that I'm stupid. I think it really is something with the Gadget...
Sometimes when connecting one Moving Head, but always when connecting more than two moving heads. Those moing heads jump a few times a minute. That really annoying 
. I already tried another Gadget of a friend, using several Laptops, several combinations of Laptop, USB-A-B-Cable, Gadget, DMX Cable and Moving Head. Almost every combinations of those five device types combined with each other... The laptop does not matter. The Moving Head does not matter. The Gadget does not matter neither. I tried with and without DMX terminator, using 3-pin dmx with adaptor and 5-pin dmx.
But... As far as I can remember the issue was always when using RDM fixtures... But I'm not sure. Turning off RMD in shell does not solve that problem... I noticed that issue first about one and a half year ago. Since then I tried a lot as I said.
When connecting any other lighting console to these fixtures there is no problem at all...
Does anybody have the same problem or can help me?
Hope you are well and stay healthy.
Thanks,
Lars
