Hi, I’ve had my nx1 for few months, and I’ve got some issues with setting up the internal output port 3-4. First two I can change and it stays how I change it, but 3-4 I’m changing and its not saving anything, and stays inactive.  
Any ideas how to fix it?  
I’m running the lates software version 4.8.1243  
Had this same issue on software 4.8.1240

I got the instructions and now it’s working great. I needed to reassaign the dmx outputs in the console tester.
