This information helps and confuses:)
Let me give you some more information!
I am using Xlights and a Falcon V3 with 2 differential boards.
my elements are on ports 22 and 23.
I have identified the models to follow and which controller/port the strings are connected too.
When I went to test, everything did not work as expected. My model with 333 channels worked fine and only first part of my second model worked.
When I broke up the link to the prior model and told it to use another universe everything started working.
I am just trying to figure out if I did something wrong or if I am misunderstanding.
BTW, thanks for the replies! it is very helpful.
