Ok, so in the picture of the product there are only 2 wires. The main power wire, and the 4 pin CPU power wire.


Now, where are the wires I am supposed to use for the power switch on my motherboard?

Where are the wires I am supposed to use for the THUMP?

If I am to supply these wires myself, where would I obtain them?

I can get everything to work just fine..I just need to figure out how I am going to get a remote wire for my amp off this thing, and more importantly how I am going to get it to control the power switch.


I have searched and checked the FAQ and found nothing.

Please help!

I don't own an M4 but I looked in the manual and found that J8 pins 6 and 7 go to your mobo ACPI.

Yeah J8 has like 9 pins sticking out of it. I have never seen a cable that would fit in that type of slot. And It doesn't explain which pin does what.

jimmler

It's a 10 pin IDE connector. Any decent electronic supply store should carry it. You'll need some 10 conductor ribbon cable to go with it. According to the manual, here's the pinout:

1) +5v
2) USB D-
3) USB D+
4) GND
5) GND
6) MOBO POWER
7) MOBO POWER
8) AMP THUMP
9) GND
10) NO PIN

1-4 are for programming the supply thru a USB connection. Not much detail on that, tho. Your power switch hooks to pins 6-7 and your amp relay goes to pins 8-9

It's all spelled out in here: http://resources.mini-box.com/online...ATX-manual.pdf

Ok, I made a make-shift connector for the J8 pinout.

Now, I have the power switch connected and it works...sort of.

No matter what I put the dip switches on, It turns off after around 30 to 45 seconds.
Plus there are 4 dip switches..when it only lists 3 dip switches in the manual.

I have tried every (seemingly) combonation of all 4 switches, and it doesn't seem to effect the time taken to turn off the PC.

I have tried using the settings for a 5 sec delay to turn it off, up to a 3 hour delay..all seem to send the turn off signal around 30 to 45 seconds after the ignition wire is off.

Any suggestions? It seems like nobody here uses this power supply..why?

jimmler

I think this is a fairly new supply and there's not a large user base out there yet. I just got mine yesterday and haven't got it hooked up yet. I have already fired off an e-mail to tech support asking for more details on 4th DIP switch as well as some other info that's missing from the manual. I'll post my findings.

care to share the e-mail? Maybe between the two of us asking we can get some answers.

ArcaneDreams

Ok, can someone confirm something for me? Right now I am testing this out on a workbench. So I am simply switching the ignition switch off.

It seems, if the ignition switch is switched off/on/off, then it takes the 5 seconds to send the shutdown signal to the PC.

In the car, when I turn the ignition from Run to Off, does it send these same signals? off/on/off?

hailrazer

With mine I had to unhook the +12v power and re-hook it up for it to register the changes in dipswitch settings.

Kind of like resetting it I guess.

ArcaneDreams

Yeah I unhooked the 12v each time I changed the settings. It appears that it only does the 5 sec off when I switch the power off/on/off as I stated above.

But then, I just found this diagram on the manufacturer's site. If you see the ignition line it does indeed require off/on/off. Perhaps a car DOES operate like that?

Rob Withey

Car DO operate like that. The ignition goes high when you switch on the engine, and goes low when you switch off the engine. Al that diagram is showing you is that ignition must remain high for a continuous 3s before the power is apply to the motherboard (and a further 1s before the power switch is pressed), and must go low for a continuous 5s before the motherboard gets switched off. Also that the hard-off happens 45s after the motherboard is switched off.

Nothing too surprising there I hope.

ArcaneDreams

No, if you look at the ignition line you see that it goes low then high then low again before it starts counting 5 seconds to turn it off.



And that is exactly how it behaves. I have the thing sitting right next to me.

So I hope cars send a low/high/low signal when you turn the ignition off.


If I simply cut the power to the ignition input it waits 30 seconds then powers off.
If I go low/high/low, it waits 5 seconds then powers off.

I can post a video if you like.

Rob Withey

That is simply saying that a rapid stop/start sequence won't trigger the off sequence, because the ignition line didn't go low for 5s. Read the colored key at the bottom of the diagram...! The High-Low/High transition is not a requirement for the PSUs operation, and typically won't happen.

I see that info and how it is shown in the graph. My first thoughts on it were exactly the same as yours. But then I kept wondering...why does my power supply behave like that?

I can tell you with certainty it behaves as I have explained.


Here is video 1. I simply switched the ignition wire to the OFF position. It takes 30 seconds to shutdown.
*Note the power supply's LED flashed 30 times. In real time it is longer than 30 seconds.

Here is video 2. I switched the ignition wire to OFF then ON, then OFF again. It takes 5 seconds to shutdown.

Perhaps when I start my car it sends a Low/High signal to the remote (Engine Crank). Then When I finally turn my car off that would be the final Low to trigger the 5 second shut-down. I don't know, I am running out of ideas.
It seems it doesn't matter as far as time between the low/high/low signal for it to trigger properly.
For instance if I turn the switch on, then off, then on real fast as the PC is booting..my PC will boot up normally. Then when I turn it off it will complete the crazy cycle and 5 second shutdown.


Any ideas? I have changed nothing at all between those two videos. I am simply looking for an answer. I most definitely do not want to install all this in my car to find out I have to rip it back out again to fix this problem.
Having my monitor on for around a min after I get out of my car may draw a bit of unwanted attention from my (possible klepto) neighbors.

Rob Withey

In both cases has the pc been on for more then the boot lockout period before you attempt to switch it off?
