Thank you for your swift answer,
I know how to drive it, i have documents explaining this.
What I don't have, is an original power supply. Two days of googling turned
up a possible 24V or 205V and I don't want to connect that to the wrong
pins...
I can't trace any leads on the board (It's tripple layered) to figure it
out, so now i have to rely on a voltage reading from someone else :(

P.S.
Did you by any chance notice a third connector with only 3 wires leading
somewhere?
