Quick question.......I've just got my CPU5 Card and I have a quick question. When I measure with my multimeter between pins 14 and 23 so the spindle on-off output and ground.

I am connecting this to a relay but I'm intrested how this works because when I hit the ON button on the PC the voltage hits a perfect 6mv but when I turn the button off it blips around? Have a look at the video? Is this correct?

Cheers
