Would anyone have a manual for a LaserMedia LM142DMX board? What I really need is the pinout information and DIP Switch indentification.

OK, get me the numbers on the two TO-220 package voltage regulators, I'm betting the 5 pin one is a switcher that makes the negative rail and the 3 pin one is a 78XX series for the positive rail. The power would then need to be 3 volts above the positive one.
Just a educated guess based on past used LM gear experience.
The 8051 based DMX decoder means one led will be power and one led will be DMX valid.
