Some thoughts. Maybe something will jump out.
Pic is programmed? With newest firmware (v2)? I believe there was an issue with 1st version.
You have output enabled in LSP? (plug icon is yellow)
You have selected an area to play in ribbon?
Try the test hardware screen in LSP?
Term is on your LE?
LE start channel match LSP?
Swap the cat5 to LE?
Get blinky with LE test mode?
YOU'RE nervous? I'm so far behind I will be late for next year.
