What would cause this.
Using the same order of wires for the left side LED pins (pins 1-48) and right side LED pins (pins 49-96) will cause that.
If you look at the lower left and right of the Ult. I/O PCB, you'll see that the left LED pin columns are labeled "
+RGB" and the right LED pin columns are labeled "
BGR+".
- Blue pins are on the inside.
- Operating voltage pins are on the outside.
Looking at your wire colors, both sides appear to be in the same order with the blue wires on the right.
- The blue wires are inside on pins 1-48 and outside on pins 49-96.
Try turning the Dupont connectors 180 degrees on the side with pins 49-96 so the blue wires are toward the inside of the board.
