To remove the long tails when the enable bits turn on and off, we removed the enable bit related capacitors on both the Control board and the Variable LED board.
The "trigger" signal (that instructs the LED's to fire) is at least ~400ns after the enable bit is stable. Run 25226 is a complete crosstalk run with variable on, but delta unplugged. Sync bit accidentally left unplug.
No change on crosstalk :( Will post pictures later.
