    Default Manual needed for a LaserMedia LM142DMX board

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

    Got a pic?, it might be one of the commercial DMX boards rebranded.

    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.
