This might be a obvious question.

I have a F48 Falcon controller. Last year I only had a small with about +/-150 pixels. This year I am +5500. My question is; how do I know which of the 12 ports do I use for which model? Last year everything was on one port. I am not sure if I need to look in the xLights manual or the F48 manual. Any guidance is appreciated. I also have this in the help topic.
Thanks in advance,
Chris
