I don't know exactly how it would be labeled, but I can gurantee that it is designed to be controlled via standard DMX. I think the problem lies with the fact that I had that signal routed on the 5 pin thru port of the blizzard splitter, which I don't think is isolated. The 3 pin main outputs of the splitter are isolated(just like the enttec splitter that used to work) so I have ordered a 5pin to 3pin turn around so I can use the main outputs of the splitter. I imagine this will fix the issue. I figured that the MyDMX 3 dongle would have had built in isolation on its ports, but after looking real quick I haven't seen anything that insinuates that it does.
Thanks for all the quick responses and direction in diagnosing this issue. I am happy to finally have and idea on how to permanently resolve this issue.
