    Itps

    i have used the handy search features of this forum and have got some info on what it does.

    I see that the ITPS is a controller that bacically turns on/off the pc depending on the ignition ON/OFF (powering down after X seconds)
    and regulates the 12v.

    But what if you dont want to turn the pc on when the car starts up???

    What i was thinking for my setup is that

    a) the Power on Button for the pc to be placed on the front dashboard.
    (gives me the option to turn on / off the pc)

    b) a seperate switch to power the amps (remote wire's 12v) *i want the pc to come on before the amps*

    im using a second battery in the back and a dc-dc psu.
    (batteries connected to each other, to maintain charge)

    i know that the ITPS regulates the power at 12v dead, to avoid power spikes.
    (can i use that feature only, and not use the startup/shutdown controller).

    + how does the ITPS connect up to the pc, ignition. i cant find any online manuals.

    thanx!

    If you use the DC-DC PSU (such as the Opus) you don't have to wire it to the power jumper on the motherboard, and wire up a power button instead.

    I've read enough to know that running a standard power supply with an ITPC isn't as reliable an option. However, in your scenario, the start/shutdown controller wouldn't be needed. Mind you, your PC is either going to stay on when you turn off the car (thus draining the battery) or it's going to shut off with the car. The controller is to allow the PC to do a proper shutdown when the key is turned off.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    You can just leave off the connection from J2 to the Sys Board.

    Doesn't seem like you can do that with the Opus though...
