    Does your DSATX shut down after 5 blinks?

    5 blinks is an overload and has happened a few times with my current setup. I'm asking quite a bit of the unit. I have an older version and im curious if those with new versions have run into the same thing. When my unit goes into overload, I never know it as the PC is located remotely. This overload causes the DSATX to NOT shut down after 10 mins of no acc and i come out with a dead battery the next morning.

    Can anyone varify that the new version does not bypass the shutdown timer when overload (5 blinks) kicks in?

    I believe that is correct.
    I was having a similar issue. It would reboot once, usually sortly after I started the truck. I brought the PC inside and set the high voltage threshhold to 18.00v and the low voltage threshhold to 8.5v. Hopefully, that will resolve the issue.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    What you are discribing is called the Fault State. The way to clear a fault state is to have ACC go low and the motherboards PS_ON signal to go high (deasserted). Next time you get into this state if you could measure the green wire with a DMM, that would tell me if your motherboard is still trying to turn on the computer keeping the fault state from being cleared.

    It's possible that when you get into this fault state, the motherboard is still pulling on the PS_ON signal. I could modify the code to just clear the fault with an ACC going low. The input voltage has nothing to do with the fault state. It is strictly based on wether the outputs of the DSATX are within 10% of the nominal voltage.


    railsGood = ((plus3_3A > 305 ) && (plus3_3A < 355 )) &&
    ((plus5A > 460 ) && (plus5A < 540 )) &&
    ((plus12A > 1098) && (plus12A < 1302 )) &&

    What kind of numbers is your diagnostic feed putting out for +5 +3.3 and +12. If they are at one end of this range, I might consider extending the allowable range. There is also 50ms of hysteresis so that it has to stay bad for that long before it will go into a fault.

    Will, I think your PSU might need to be updated with my firmware fix that can't be done remotly..

    Jeff, can i pay you a deposit plus shipping and have you send me out a 2nd unit? It can be a refurbed. I have no issue with that. When i get it I'll pull mine and send it back to you? Then refund the deposit?

    I'd like to get this done but i have a couple road trips coming up that I would hate to be "tuneless"


    In regards to your questions, I will keep an eye out but it can be tough to catch it when it overloads. I have been hibernating manually everytime i shut down the car. I will test next time i catch it.

    Okay, I just installed the 3 pin fan with my DSATX to stop it shutting down in this hotass summer, but now when I try starting the car and carpc w/ ACC I'm getting 5 blinks and whole lot of nothing. What can I do? I still have the same configuration as before, but the the new fan that is only using 1.5 watts. Help please.
    This is your life, and it's ending one minute at a time.

    Jeff,
    Exactly the same happens on my machine.

    1.The DSATX works fine.
    2. I shutdown the pc/it shuts down the PC
    3. Come back later and restart car (ie: ACC goes high)
    4. It calls a fault state (5blinks)
    5. I pull the Fuse to the DSATX (Because nothing other than removing VCC will relieve the fault.)
    6.Put fuse back in - PC boots as normal

    I'll try monitor that voltage and get back to you.
    But in my case, Id probably prefer (need) to have the Fault State ignore the PS_ON signal.

    I'll also check the MB turn on pins to see if its active high or low.

    Cheers.

    I can make an update for you that doesn't look for PS_ON going low to clear the fault.

    Thanks, that would be perfect

    And, in your opinion, easiest way to include a 'HARD OFF' switch = putting a switch inline with VCC (or one that switches a relay that passes VCC)?

    Reason:
    Poor soundcard drivers sometimes cause my PC to hang/play trashed sound at FULL VOLUME, so i need something to "immediate off" the system. I looked at the USEROFF header pins, but these ZERO the countdown timer when ACC is low, and the above situation has occured to me whilst doing 110Kph on the highway with no way to turn off ACC in a hurry.

    The switch will be in the ON state 99% of the time, but I need it just as a failsafe (might even make it a momentary one to act as a reset button instead).

    The Reset switch sounds like the best solution. You'd need a 20 amp relay or a really beefy switch for a "Hard Off"
