USER ERROR with DSATX

nigwhyrito · 09-16-2006, 03:16 PM

well I figured I do some searching before I posted
So heres my problem.

I think it is something I did wrong I think my dsatx works.
__________________________________________________ _____
dsatx wont turn on when I put key in ignition and set car to acc or start.
no red led.
---------------------------------------------------------
In dumb psu mode jumper on b1 and b2. I have power to dsatx and solid red led and pc will turn on with pc power switch.
-----------------------------------------------------------------------
Steps i have taken to troubleshoot

1. Search the forum found great tips.
2. Reset dsatx using A2 and B2 jumpers.
3. Put a load on dsatx 1 3.5inch hardive..
4. tested with a fluke meter.
5. tried swapping 2 pin wire on g1 and motherboard
6 tried differnent mobo a via m1000k pins 6 and 8
7. pulled the yellow blade fuse
8. using 10 awg wire is running 14ft for vin
9 ground is 10awg wire is running 1ft for gnd and connected to ground of car .005 ohms
10 adjusted pot 1 and pot 2 counter clockwise and clockwise. no more than 270 degrees,
11 tried both motherboards in the house on a standard atx psu.
12 acc wire is 18 awg is running 13ft to cigar lighter T-05 connector G
is schematic of car. I may have used wrong wire for acc for dsatx not sure.

-------------------------------------------------------------------------
Voltages
Car turned on
vin = 12.44
acc =12.44
gnd = 0.00 ohms is 000.2

Voltages
car turned off
vin=12.58
acc=6.73
gnd=0..00 ohms is 000.2
---------------------------------------
car is a kia Sorento 04
system specs
1 dsatx
1 gx260n 512mb 2.0ghz
1 via epia m10k 256 mb 1.0ghz
1 3.5 in hardive cheap hardrive.
--------------------------------
the gx260 is my final install just doing some in car testing. before the final mounting. and my complete independence from VIA mobos

So if any one can help Please feel free to start spoonfeeding me, My mouth is wide open.... oops i shouldnt have typed that hahaha

I'm pretty certain the problem is that you're getting 6.73v on the ACC line with the car off. It should read 0v with the key in the OFF position.
I'm no expert, but I believe that line is getting the ~7v in order to keep the time in the clock.

Can you tap into a different ACC line? I suggest tapping into the radio power line.

nigwhyrito · 09-16-2006, 06:31 PM

Thanks darque I will give that a try tommorow. I didn't want to use the radio harness because I read a lot of posts where people said do not tap into the radio harness, plus I will be still using my factory radio. I thought the cigar outlets were the way to go. well i cant wait till tommorow it is raining real bad here.

DarquePervert · 09-16-2006, 10:00 PM

Tapping into the radio harness to provide the constant 12v power is a bad idea, certainly. For the sense wire that controls the smart PSU (DSATX in our case) works just fine. That's how mine is wired.

nigwhyrito · 09-17-2006, 11:51 AM

well darq i tried what you said using the acc wire from the radio on mine it is g/o pin 14. same results psu only turns on in dumb psu.
I read the manual thoroughly I shouldnt have any jumpers on except for the 2pin wire from the mobo header. I pulled the fuse and also reset a2 and b2 with fuse in and with fuse out..
The voltages are different now
car on
acc= 12v
vin=12v
gnd=0
car off
acc=0v
vin=12v
gnd=0

Any ideas please help. zootjeff i have a dumb psu(it only works in dumb mode)haha. I am in no way bashing your product... i feel the dsatx is great design just wish i could get mine to work correctly.
here is schematic.

It wont be hot to much longer here. I cant work on the truck in the cold please guys hellllllllllllllllllllllllllllp

when u mesure voltages, are both ends of the wires attached to something?

to get accurate reading you need to unhook the wires from the dsatx, and attach the multimeter to the unhooked wire,

you could be getting different voltages then you think.....

nigwhyrito · 09-17-2006, 01:01 PM

well gameboy i am open to any suggestions. so i will go try that...
I was measuring the 3 screws on the dsatx with the wire firmly attached.
out to the truck i go.
--------------------------------
back from truck same voltages readings
with wires removed from dsatx.
put wires back on after getting voltages put fuse back in.
then put key in the acc position nothing came on.
put b1 and b2 jumper on psu started rigth up...

nigwhyrito · 09-18-2006, 12:43 PM

So does anyone have any ideas out there or is it possible that the PSU acc circuit is fried... Does anyone think using the brainstem and setting it to load factory defaults might help??????

zootjeff · 09-18-2006, 09:02 PM

How old is your PSU? What is the rev number on the board? What does the sticker on the back say?

If you want you can send it back and I can look at it and load the latest firmware.

nigwhyrito · 09-18-2006, 09:46 PM

thanks for replying zootjeff. I am wondering if the firmware issue could be it.. reason being it turns on dumb psu mode(bench tesying) the users i read with firmware issues either get the 5 flashes or no power what so ever.
I will try and get the revision number tommorow. its 11 oclock pm here and the psu is outside in the truck.

Most of the time it goes into the 5 flashes mode, but sometimes it just acts weird with that firmware bug. Units ending in 4805 can have this problem.

nigwhyrito · 09-19-2006, 07:13 PM

uh jeff I dont know how old it is. i guess 2005
the rev number says PF8035 (C) Mpegbox 2005 Rev 1.2
uh i dont see a sticker on the back...
I purchased the brainstem with it. i have not used it yet its still in the original packaging sealed up.
do you think setting the dsatx to factory defaults with the brainstem might help.
I just think its weird how it works in testing mode (dumb mode) jumper b1 and b2. Is there any thing in the brainstem advanced config that would tell not to turn on by acc..
you have a great product jeff i just wish i could get it to work...

nigwhyrito · 09-22-2006, 06:12 PM

_____update______ this JUST IN DSATX is working___________update______
Well jeff thank you for your support.

I know you said I have the old firmware but i used the brainstem and set it back to factory defaults.

Thank god for the FAQ on how to use a old dc powersupply to power the dsatx. it was darque and someone else i think.. they made it very simple "cut all the yellow wires and splice them together into one hunk..."

I was not about to bring the battery in the house. or drag a pc out side..

I tried it today and she works like everyone described ... flawlessy

This is the first time I had seen it in action and I was utterly amazed.
You have a great product Jeff....but you said my firmware was old..

So I am debating should i send it back or not...

.I am so anxious to complete my 2nd carputer... the first was so ghetto it did not deserve any pictures

this one i am going for an oem look... tommorow is a big day of reinstalling.. new firmware or keep old firmware and wait for it to mess up.... Its just not fair...

DarquePervert · 09-22-2006, 06:31 PM

Glad you got your issues sorted.
Jeff would be the one to tell wou how necessary it is to get the firmware updated. If it's working the way you want, it may not be that big of a deal.

nigwhyrito · 09-30-2006, 08:12 PM

update this will make many laugh i am laughing on the outside but crying on the inside.... any dell Gx150 - 280 owners please help me.
Well as i posted the dsatx is working like it supposed well i thought it was.. after i reset it to factory defaults i got the dsatx to come on with acc.
now i turned it off and the board turned off i was happy...but it was a false pretense....I did not have my xenarc hooked up to see the shutdown.. so i pluged my lcd in to hopefully tweak the system..
When i turn off the key the dsatx is not sending the shutdown pulse to mobo. bio was setup for s3, set hibernate and then i tried standby when i press power.. Yeah i tried both options.Well the only thing the dsatx is doing is shutting down hard after the predetermined amount of time from the pots... if i short my two wires then the pulse is sent..
So i searched the forums some more and tried to make sure my power switch wires were correct.
than checked with meter.. i was getting +3volt on the positive wire and 0volts on the wire going to gound. okay i thought since the normal way is not working i will make the other cable for inverted mobos....
Well ten minutes later i connected to my dsatx started up the car and then the monitor flashed the pc posted then she just shut down HARD.. then the yellow led just lit up on the board and the fan spinnned.. so i waited for the dsatx to finish its countdown... tried again nothing... the fan spins no video no post.. Crap i think i burned the chip so i check the chip on another board chip is goood. Darn I burnt the mother board up .... this was last week so i got a hold of another mobo same model and went again making the original cable... maybe its the way i making the cable.. i used the 2 pins on the powerswitch board they are diagonal from eachother and when shorted they turn pc on.. well today i went to installing new mobo and guess what same thing.. turns on but will not shutdown.. So i figure hey maybe brainstem can be of use here.. okay first attempt at hyperterminal it elles me some other application is using my comport i am going crazy im like uh no i just rebooted.. Then i figured I guidance might be the culprit.. well it was.. so i opened i guidance and changed the comport it was looking for..
Next I hit ,E, D,Y and say hmmm i wonder if setting the factory defaults will do anything well they didnt.. so then I say hmm is pc getting the shutdown pulse from dsatx so I hit E, @ ... the darn pc then goes into hibernate.. I was shocked.. So i t came back from hibernation. I then rebooted..used the brain stem to maybe change pulse duration for mobo... E,S080200 this sets pulse duration to 200ms well just as im doing it the pc decides to go into hibernation.. I was like hmm is my battery dead, has the dsatx noticed my battery level is low. okay i will start my car now. well on start up the monitor leds was pulsing and the motherboard was pulsing as if it wasnt seeing 12 volts then i got scared turned car off fans was still spinning and there was no video on lcd.. yep another fried motherboard.....
next weekend I will try again...
If anyone has any advice please pm me..or post here I will also post the pics of how i am using the two pin jumper for power.. Dell uses a board and a ribbon cable
