    Still working on the DS-ATX

    Well the power supply does look like it is running like a solid product now. My only issue left is the power_on. I built the reverse polarity switch and now the motherboard starts on command. The only problem is it turns off after about 3-4 seconds. It seems as if the 5v going to the JP1 is constant and not pulsing. Adjusting the pulse width does not appear to affect operation. I've set the pulse from 1200 to 2000 to 200 to 9000. I get the exact same thing every time. If I pull the cable after it starts, the computer boots up. As soon as I plug the cable back in the computer shutsdown.

    Maybe I have build the cable incorrectly. Everything was clear up to the point where the instructions say,

    9. Connect the connector and wires as shown.

    Looking at the diagram http://www.mpegbox.net/DSATX/DSATX_Pos_Sw/

    Under IMG_8595.JPG, only one wire is connected on the left side and wires on the right are clearly seen. So where does the white connector go? So far, I connected the wire to the resistor on the outside of the heat shrink. Does that seem right to everyone else?

    Yeah, I talked about it with a friend yesterday. I'm not sure what relay to get. My voltmeter is slow and cheap so it shows that the PS is putting out .12 volts when it sends the signal. I'm not sure which relay would be appropriate for this application. Any suggestions?

    I used just a regular 30Amp automotive relay that I had laying around



    I will see if I can draw up a nice lil diagram tonight to show you exactly what to connect to what using a standard automotive relay

    Wow, does this sound familiar? Did you figure this out? You are using the iBase896 board that I was before. Bet this may be related to the newer intel boards.

    Looks like I have the exact same issue as you! I tried the 30A auto relay and still had this issue. I tried to change the timings, but could not get a connection via the brainstem. Sent it back to jeff at the beginning of this month to see if it can be repaired.

    Yes the White wire is not used. You just need the red wire. Then you have to make sure the red side is connected right.

    You also need to make sure there is no power on after ACC Fail. The BIOS needs to be set to "STAY OFF"

    I just had this issue on shutting down on a customers car.. it would start up great... rn.. perfect but on shutdown it would go into standby or hibernate.. whichever I picked... but then after a couple of seconds it would boot right back up

    turned out that in the BIOS I had it set to where the USB devices as well as the LAN could bring it out of standby

    I hope that helps anyone

    Thanks for the reply! I really just think I wired it wrong. I just moved to a new apartment and when I have the garage setup again for my customizations, I'll give it another try. Hopefully I can get it working sometime this winter.
