    Will a relay work for this ????

    I will like to power my lilliput lcd via the 12v rail on my molex connector.

    I have the dsatx and i have it set to turn off the pc after 12mins from me exiting the car.

    I do not want the monitor to stay on for 12mins after i have exited.

    Is it possible to attach a relay and i have wired to the acc line?
    that way the screen can turn OFF wen i take the key out of the ignition?

    The DSATX has an additional 12v output.
    I'm not certain if that is controlled by the shutdown controller timings or not. If not, you can use that 12v output for your Lilliput, and it will do exactly what you need.

    Another way of accomplishing this is to use the egg-shaped regulator to power the screen directly form an ACC-controlled line. That is probably a far simpler means of accomplishing what you want.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    i forgot to mention a few things

    the lcd is currently powered by the acc controlled cigarette lighter.
    but the screen flickers when the bass hits. (i have a sub in the trunk)

    so my intention is to power the lcd with "cleaner, more stable" current; connecting it to the dsatx.

    the only problem with that configuration is when ever the carpc turns on , so will the screen.
    i live in a bad neighborhood , and i use remote start.
    i dont want to have the lcd on, attracting attention wen i am not in the car.
    hence, my quest for a acc controlled line running from the dsatx.
    i still want the pc to turn on with the car, and off after 12mins etc.

    hope u can follow my thought processes...

    here is a pic of how i want it to look.

    the dsatx can be started by both the remote start or the acc line.

    Sure. That'll work fine.
    If it's a standard 4-pin relay, just connect it like normal using the DSATX as source.
    30 - Positive from DSATX
    85 - Ground
    86 - Positive ACC
    87 - Lilliput

    Cheers,

    Yes.

    Remember to use a relay with a diode...
    because energy can store at relay coil and kill your psu...

    Relay

    a good quality relay like bosch will have it from factory.... or a 1 amp diode will do...
    like this...
