Just getting started on my first carputer project, and have acquired the above Opus power supply from a friend.
I looked up the datasheet:
On page 3 it says to connect the input connector pin 3 to "ignition or power switch".
My question is this: is it looking for a momentary pull-up to 12v on this line, or does this line need to be *held* up at 12v to keep the PC running? Another way of asking this might be: do I connect to the START or the RUN position on the key barrel?
I think it probably needs to be held up at 12v to keep running, then it sends the shutdown signal after the 12v disappears, but I thought I should check. :-)
Thanks in advance!
