Wiring of laser upgrade for mScara

#1

Hi all,
My laser upgrade came with the laser not wired to the plug. I need to know which wire is positive(+) and which is negative(-) The plug is yellow/orange and goes to terminal M2 on the circuit board. The wires are black and one has the voltage etc marked on it and the other has white stripes on it. Can any one help as Makeblock technical department haven’t answered me yet.

Thanks in anticipation

Fred

Hi all,
I managed to get a reply at long last from makeblock. both the wires for the plug are interchangeable so it doesn’t matter which way round they go.
