Thread: Forcing a hard reboot

    Forcing a hard reboot

    I've just installed a couple of 4500's and had one of the magnetometers wire's crossed. In debugging my screw up, I could not find a way to have just one of the 4500's hard reboot. (They both have backup batteries as well.)

    Is there a way to turn the 4500's off or force a reboot/restart without killing the power to the unit?

    I elected to not put an independent power switch between the elect bus and the EFIS's assuming they would have an off switch and adding a switch would just put another failure point in my wiring.

    I probably missed something simple but thought I'd ask before making it back to the hangar tomorrow.


    Thanks,
    Doug

    Hi Doug,

    I don't believe that there is. Based on a June 2008 email w/ Rob, the up and coming 4500's did not have a means to reboot the unit from the front panel. I'd be interested if AFS changed that aspect of the h/w, though.

    Regards,

    Hmmm, a good reason to use a pullable breaker on these units??

    This might do what you want. Enter the calibration menu
    [CHECK] ‐> [MAINT] ‐> [ADMIN] ‐> then hold [CALIBRATION] button for 2 seconds.
    Then press return to reload the software.

    Good idea, Jim! Keep in mind, you can only do that when there isn't any airspeed. In Noah's case, I think this would have worked. Personally, I'd want the unit(s) powered off while moving any wires around.
