Put together the control box for the garage door matrix panels. It contains two power supplies, and 5 smart differential receivers. They are daisy chained off of each other, so only 2 ports on the F48 are consumed. Each side of the matrix uses 8 outputs. The 5th receiver is for the snowflakes or spiders on the face of the garage, depending on the season. They would be directly on the outside of the wall to where this box is located.
