    Jumper settings/ general power questions

    Hey everyone! I have all my stuff together and I am assembaling it now for bench testing.

    Some questions came up.

    1. I notice that on the m2-atx psu that it has jumpers and they set it to do differant things. The book as a suggested setting of putting the jumper on B which states 5sec/2hours.
    So does this mean it will start 5 seconds after the key is on, and go into hibernation 2 hours after the car is off?

    2. Can I put a toggle switch in the main powerline to the carputer, so that on really cold mornings, I can turn it to off before I put my key in, so that it doesnt try to spin up?
    I would rather wait till the car is warm on fridged mornings and THEN flip the switch and let it boot. Is that possible? Seems like it should be.

    1. No. 5 seconds after you turn off the ignision, the M2ATX will initiate shutdown. After 2 hours, it will cut all power to the PC.

    2. A better solution that is easier to implement would be to put a switch on teh ACC line, and you can use it as a valet switch, basically.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Thank you!
    That valet idea is a great one.

    So even though the power is running to the psu, the acc wire is the one that really tells it when to start up?
