Swicth on has been random, sometimes it would work fine, other times it'd start to power up then switch off again.

Lots of head scratching and setting changing ensued; I tried a couple of different M4-ATX's and a couple of motherboards, still no success.

I then tried a brand new motherboard, identical to the previous ones BUT with an updated UEFI. It fixed all the problems!

The old UEFI was Phoenix Securecore Tiano version 2.1 and this was flaky; version 2.2 works fine.

I'd suggest anyone experiencing issues check to see if Phoenix UEFI 2.1 is installed (The version number is displayed on the Phoenix splash screen). It'd also be worth updating the motherboard BIOS if a later version is available.

I can't say whether this will fix anyone else's problems but it worked in this case. ]]> M4-ATX davehills http://www.mp3car.com/showthread.php?t=155636 m4-atx/152956-how-to-turn-on-m4-atx-without-a-pc-to-power-acccesories.html Fri, 10 Aug 2012 02:16:22 GMT SO all i need it two 5v rails and a 12 v rail to tap into.

If I’ve read the document correctly, the... I’m clearly doing something wrong as the device (computer) powers up regardless of the state of Ignition.

If I’ve read the document correctly, the order is:
GND, Ignition, 12V (Depending on which way you look at it, it could be reversed, but same order)

As soon as the 12V connection is made, the device powers on, regardless of the state of Ignition.
Ignition signal does change from 0V to 12V as per key in ignition. (measured)

Device is in P1 mode, “On, Off, Off, Off” (Down, Up, Up, Up)

“P1 (recommended): Sends ON pulse to motherboard when ignition is ON for more than
5 seconds, sends OFF pulse to motherboard 5 seconds after ignition is turned off. Waits
another 60 seconds and then shuts down 5VSB to conserve battery. In this mode, the
M4-ATX consumes less than 0.5mA.”

As per the manual, it’s not supposed to power up the mainboard, until Ignition has changed to 12V for 5 seconds or more. It’s currently on my desk with nothing connected to Ignition, it still powers up when 12V is provided to the 12V connector. A voltmeter confirms Ignition is 0.01V when measured against GND.

For completeness, I’ve not connected anything to the USB port and/or used the software to connect to the unit to configure it. It’s all as per factory with the exception of the DIP switches.

Clearly, I’m not interpreting the manual correctly and I’m getting it wrong. I can supply pictures of input cables and DIP switches if it helps to provide clarify on what I’m doing wrong.

Btw, it was brand new a few months ago, but been a bit slow to build and configure the equipment, and ignored the issue while i was building it on my desk. Now that I'm trying to fit it to the car, its more than a little annoying.


Any advise?

I have connected this to the inner pin of the J6 connector on my M4-ATX. This does it's job sending a signal to the wiring harness and in turn to the amp to turn the bose amp on.

My problem is I get bad audio feedback until the PC boots to the windows log in screen. Once there the noise is gone and everything sounds crystal clear.

One solution I am working on is setting up the PC to "instant on". However it would be great if I could keep the amp from coming on until I am at the windows log in.
Is there a way to modify (increase) the length of delay for the thump pin header turning on the amp? Or did I fail at some point in my setup? I do not have the ground pin (on the J6) hooked up to anything currently.

The actual m4 board is warped... Not bad enough that I'm worried it won't work, but enough that you can definitely tell... Could be due to the way it was packaged. The m4 housing was crammed in the box, while the m4 was just wrapped in bubble wrap. It wouldn't have been hard for the case (which was in it's own box) to have deformed the board.

Secondly, the housing itself. It came with an 80mm fan. I assume you're supposed to hook it up to the m4 board, but it just has bare wires to hook it up with. At the very least, they could have put a connector on the end so that I could just plug it in... Now I have to fabricate my own, or solder it on.

It seems like they threw in the bare minimum, and that's it. As far as the actual board, aside from being warped, it looks very well put together. It seems well thought out, and professionally made. It's really too bad they skimp on everything else. Last example... Most power supplies include the screws to actually attach the power supply to the case... This included JUST enough to get it to hold together, but notably misses screws to mount the terminal to the housing. It will work without them, but it would have had a much better fit and finish with them. I guess I'll have to dig some up.

Hopefully it works. ]]> M4-ATX X219c http://www.mp3car.com/showthread.php?t=150432 m4-atx/150092-m4-atx-hookup-complete-noob-first-timer-help.html Thu, 29 Dec 2011 04:19:37 GMT As per the thread title. up until now I have been using an AC PSU and inverter. inverter died (and was taking up room) so I purchased an M4-ATX...

I have had this setup for around a year now and It just recently started doing this new trick. Every time I key the car on with this hooked up the computer boots for 4 seconds then powers off. I have the amps tied into the delayed boot as well. They power on and stay on, but as soon as i remove the key all power off(within 1second). This is new from before as they used to be on a one min delay with the jumper settings I chose when installing I used a multi tester and checked the power switch jumpers on the mobo and it seems that when I put the key in the ignition it completes the circuit... then keeps completing the circuit rather than the expected pulse to power on the mobo. I disconnected the pulsed power on from the power supply and connected it to a temp momentary contact switch and that works fine so the motherboard and everything else seems to be ok.

I have just installed my carpc in the jeep but am having what I think is an under powered system issue.

- 4 gig ram
- and I am also powering my Lilly 699 from the m4 as well.

Situation: when system is on, I get a slight flicker on screen. The flicker is not at a constant rate and is NOT engine rev dependant. This flicker continues even in reverse can mode on screen.

Does this sound like the M4 is infact under powering my carpc? The M4's description clearly states that it can power a dual core processor.

I have the M4-ATX plugged up to my motherboard and my motherboard seems to be getting power (the red LED on the mobo comes on) however, it never boots up or even tries to. The green light on the M4 blinks rapidly a few times, then just blinks forever at a slower rate.

The M4 is plugged in to the mobo, and the J8 jumpers 6 and 7 are plugged straight into the power switch on the mobo.

1. My first question is if I'm plugging the jumpers to the correct place on the motherboard? It should be attached to the PWR switch where the case normally is plugged into so you can power it on. If this is not correct than I am an idiot, and if you could inform where I need to plug them in I would greatly appreciate it :)

(i have a regular power supply that turns the computer on no problem at all) This is the 2nd M4 that has done this. Is there some setting that I have to have in the BIOS of the Mobo to get it to work?

I've had my M4-atx for over 6 months now and its been operating fine, until yesterday... :/
My carpc would not boot up when the car was switched on! so took it all out and bench tested with a normal ATX psu and it booted up, put the M4-atx back on and manually shorted the power pins and it booted up just fine, so the M4-atx is working fine execpt it's no longer sending the power on(or off) pulse.

I tried resetting to factory settings with JP1, changing modes from P1 to P0 and some others and even made up a USB cable and installed the M4-atx software and fiddled with the settings(pwr on pulse etc.) as well as multiple combination's of the above to no avail... :( I find with the USB cable connected and the M4 in P1 mode that the PC hibernates fine even without the mobo header connected(obviously gets signal over the USB) so my solution for now is to wire a small push switch in parallel with the power switch header and use it to start the pc when starting the car.

I have searched on here and also emailed mini-box.com(waiting for reply) any one got any other suggestions for me? I'm currently studying electronic engineering and I know my way around circuits, I also have a PIC programmer and some experience programming them, according to the M4 software the M4 firmware is version 2.1 (latest according to mini-box change log) perhaps the firmware has become corrupted, if I could find a copy of v2.1 would it be worth to try re-flash it?

I'm moving city's in 2 weeks and I have a 1600km solo drive ahead of me so I NEED to get my CarPC 100% before then! :P

I have a noise problem with my M4 ATX.When i start the computer after 4-5 seconds a noise starts coming from the speakers if i start the car the noise increases as i throotle up.
I know that you are going to say ground problem,thats what i thought at start,so i begun to checking everything until i get to M4.

I have for source an Alpine 9882 Ri,and bought the original alpine cable to make an aux in,all the test made with the cable on the air to check if it is ok.I do not have an amplifier and i use for the speakers the amplifier of the alpine.

Thats what i did
1.checked all grounds-everything ok
2.removed the step down from 12v to 5v-Still have noise
3.all the power cables where from one side (drivers side) i even still removed them out and still have noise
4.made a half meter only ground cable and connected it to a clear spot to the drivers seat belt just in case that because i had 2 meter before ground cable
made noise.Still have noise
5.Removed all usb-still noise

Then i believed something was wrong with the computer so
1.removed everything from inside the computer (including the M4 ATX)and builted it outside the car in case that i had somewhere problem with my box grounding something that i couldnt see),nothing still the same noise.

I Even took 2 new cables from the battery took them outside the car and powered the M4 STILL THE SAME NOISE

so finally i removed the M4 ATX and connected its regular power supply AC powered.SUCCESS no parasite sound no more.

Another thing is that i noticed that when i took the ground cable out while the computer was working nothing stopped and continued to work with only the 12v cable connected.How is this possible?

I am working to eliminate this noise for about a week now i already have again half of the car disassembled,My nerves arent in a good situation,and i stopped just to write to you because if i continue thinking inside the car i WILL BREAK EVERYTHING INSIDE.

Does anyone had any similar problem?Any suggestions?Shall i return the M$ back or there is something that i can do?

Any advice would be helpfull.Thank you ]]> M4-ATX tsakimak http://www.mp3car.com/showthread.php?t=145540 m4-atx/144444-m4-usb-cable-question.html Thu, 07 Oct 2010 01:20:01 GMT If I got the USB cable for the M4, how would it communicate with the mobo, since it isn't connected directly to the mobo.

Startup / shutdown work fine if I use it in that setup, no problems at all.

But I want to move over to using hybrid sleep, and this is where I am having some issues.

If I turn the ignition off, then the computer goes into standby, and if I turn the ignition on within 1 minute, then the computer comes out of standby, no problems.

If I leave the ignition off for longer than 1 minute, then it resumes from hibernate, so the M4 is cutting the 5VSB line at the 1 minute mark.

However, if I use the M4 configurator, and set the P1 Hardoff time to never, then it STILL cuts the 5VSB after 1 minute!

Even if I set the P1 Hardoff time to say 10 minutes, it still does a hardoff at the 1 minute mark, and makes the computer resume from hibernate.

So I am not sure, I would love to get the hybrid sleep working, with a time of around 24 hours. I always get back into my car within that 24 hour period, and if I am away longer, then I would like the computer in hibernate mode, and I would generally have the car on a battery maintainer as well.

Am I missing something? It seems like the M4 is ignoring the changes to the hardoff time, and just cutting at 1 minute.

I checked the voltages, and it doesnt look like it is triggering the low voltage cutoff either, the battery is currently at 12.1V, and the cutoff is 11.1V. ]]> M4-ATX Chester http://www.mp3car.com/showthread.php?t=143100 m4-atx/142622-j6-antithump-not-working.html Sun, 11 Jul 2010 07:34:47 GMT Hey, so I have my carpc wired by a Button, NOT by the m4atx.

But it has more issues then People magazine.

It works fine in standard PSU mode, but every other it just does the blink every minute twice and won't come on for anything.

Now...In PSU mode, it will occasionally, when I turn the ignition off, shut down right away, indicating it thinks I just turned power to the remote ON, rather than off.

I have a (normally open) single poll single switch hooked up in parallel with the two pin connector going to pin 6&7 on J8 for power on/off, then of course going to the 2 power on/off pins on the motherboard, so I can manually control it. But I was of course looking not to really need to use it much if at all.

This has been a project I kept on the workbench for quite some time as I had other issues I needed to resolve first. It did some of this rather backwards functioning when I originally got it, but it DID at least work with the standard first switch on (P1) configuration. The only thing that changed was I got a Zotac MB to replace the Intel, as even with this board with a VGA out I had to make an ad-hoc VGA cable due to room constraints.

Has anyone had this issue? Is there a way to resolve it? Or should I just go with my gut instinct, order an OPUS 320, and shout "Pull" for this one once I can replace it?

As alwayz i want to test it, therefore i let the dip switch to just power supply mode with an external on/off switch from the board.

Unfortunately, nothing turn on, but there is a LED light power on from the M4 ATX but not from the motherboard. Then i do some Volt check, notice all the wires are all 12V positive (the - wire, the acc wire, yellow black, red ....)

I expect that this question has been answered already as I've found several threads complaining about the issue, but haven't found my solution yet. Here's my setup:

- M4-ATX
- Diamond Audio D3600.1 (sub amp)
- Audison SRx2.1 (comp amp)
- Image Dynamics IDQ10V3
- Morel Tempo 6 two-way comp system

I am getting a killer turn on pop when booting my computer. I didn't receive any instructions or paperwork (or even a box!) with my M4-ATX; nothing but the power supply, harness and turn on jumper. I took the liberty of looking up the manual online, and found that I can use jumper J6 to prevent amp turn on thump. Since I have two separate amps, here's how I hooked it up:

I got a two pin (non-shorting) jumper and soldered a couple wires onto it (shouldn't I have received a jumper for this with the power supply, BTW?) Anyway the pin at the edge of the PCB is ground, inner pin is split into two wires and those are connected to the remote turn on leads (one for each amp).

Alas I still have a massive turn on pop. I spent a lot of money on these speakers and amps and I know this isn't good for them. Did I do something wrong? How do I stop it from doing this???

Thanks!

I searched through the FAQs for something like this but came up empty-handed. I have a M4-ATX PSU powered up on my workbench and for some reason it's not sending the shutdown signal when I kill the power. Luckily I wok at an electronics manufacturing company, so I have a transistorized adjustable linear power supply (TALPS) to play with. Currently I have it hooked up like this:

The TALPS is set at 13v, connected to power and ground on the M4. I have a jumper wire from the IGN terminal to the +12V terminal on the M4. I also have the "thump" harness connected from pins 6/7 on the M4 to the on/off headers on the motherboard. I have dip switch 1 on the power supply ON so it will delay 5 seconds before powering on, and wait 1 min after the ignition is off before turning off the 5vsb rail.

Everything seems to be working fine until I kill the power. I turn it on, it waits 5 seconds, starts the computer and it boots fine. When I kill the power, it isn't sending the shutdown signal. It just turns off like I killed the power on a normal ATX power supply. The instructions for the M4 don't tell me crap, so I'm at a bit of a loss.

Any ideas why it wouldn't be sending the shutdown signal? ]]> M4-ATX ThePistonDoctor http://www.mp3car.com/showthread.php?t=132139 m4-atx/132060-is-this-right-wiring-up-with-m4-atx.html Wed, 06 May 2009 07:20:39 GMT Hi,

I've wired up my M4-ATX like this, is this right or good way to do it:

- I got positive wire with 60A fuse to power block(sharing power to 4 points) and from power block one positive to 1F condensator -> condensator positive to M4-ATX positive

- I got M4-ATX negative to one condensator

- I got M4-ATX ignition from my car stereo(ISO adapter ignition), so I'm using same ignition with M4-ATX. And same ignition to audio amplifier

Is this right way to do it? Can I use same 60A fuse with my audio amplifier and M4-ATX?

It would be nice to see pictures of your wiring ups with any power supply. ]]> M4-ATX temeks http://www.mp3car.com/showthread.php?t=132060 m4-atx/131883-stud-size-of-m4-atx.html Wed, 29 Apr 2009 21:43:01 GMT Because I'm using my own case for my project, I want to fabricate a nice connector like that on the back of the Voom2.

Here's what I'm thinking:
- 8 gauge from the battery to the distribution block.
- 16 gauge from the distribution block to the male "mini-fit JR".
- 16 gauge from the female "mini-fit JR" to the spade connectors on the M4-ATX.
- Spade connectors into the studs on the M4-ATX.

So, couple questions.

1. Does anyone know the stud size on the M4-ATX?
2. I'm planning 8AWG wire to a distro block, can I run 16AWG from distro to the M4? This run won't be very long, maybe a foot.
3. Looking at the catalog I have a couple options, Snap Spade, Flanged Spade, Spade Tongue. I'm leaning towards Snap Spade, it looks like it should fit - again though the stud size is going to kick in. Any feedback on which type of Spade?

I figured this was the best area to post this question. I searched both with Google and the MP3Car search, but couldn't find an answer.

So I've bought M4-ATX power supply and here is what I did:

1) First I made USB-cable for getting some information about M4-ATX, it worked as expected and I was happy:dance:

2) Then I putted motherboard(P4S333-VM)and M4-ATX into my car and powered things up! I switched computer on EVERYTHING WORKED AND I WAS HAPPY AGAIN!:dance:

3) So, my M4-ATX worked well but I wanted it to start computer automatically. I took wires off and pushed DIP SWITCH 1 down(5sec +1min). I wired everything up and nothing happens(yes I powered up my car also). I was sad and took M4-ATX out of car and went into my house and plugged M4-ATX to my laptop -> "Windows doesn't recognize USB-device". Now I was like what the heck. So I was thinking like Einstein and tried to put DIP SWITCH 1 to off state -> then Windows recognized M4-ATX. HMM:dance:

4) So my problem still wasn't solved and I took couple hours checking posts here at MP3Car.com. Someone said that resetting factory settings do the trick so, then I did that. Wired thing up and then I was SUPER:dance:!!! So everything worked as expected! (Except windows doesn't recognize M4-ATX if DIP SWITCH 1 is down:violin:)

5) I took my girlfriend with me and we went little trip with my car and my super cool carputer! Everything was supercool and music was playing loud and everything was perfect until-> We went to store and carputer shutted down properly. Then we came back and powered up my car -> carputer didn't boot up?!?!

6) We drived home and I was thinking and figured it out. Somehow my computer did an error and so it shutted down always when it came up. I fixed it and booted up computer manually(connect pwr pins). Then I shutted it down properly and connected M4-ATX powerup pins to my motherboard and powered up my car -> NOTHING HAPPENS! When I power up my car, motherboard gets voltage(motherboard led is on) but doesnt boot up, and if I power down my car motherboard is off(immediately). Now it boot up only manually and it's not nice...

7) I thought that if resetting factory defaults worked last time, it will work also now. I did factory settings reset but it's still same! Power up motherboard but not computer!!! Oh I almost forgot, if I have power pins plugged in motherboard and power up my car-> NOTHING HAPPENS, but if I take off power pins from motherboard-> computer boot up!

I did again factory settings reset but nothing happens. Now my motherboard doesn't even get any voltage and I'm like:laser:

--------------------------------------------------

So, compressed:

1) "Windows doesn't recognize USB-device" if DIP SWITCH 1 is on(5sec + 1min)

2) DIP SWITCH 1 setting worked when factory settings reset was made, but after couple boot times it didn't work anymore. Doesn't work if I do factory settings reset again.

3) If DIP SWITCH 1 is on and power up pins are plugged to motherboard -> NOTHING HAPPENS, but if I take power up pins off -> I get boot up

4) 5sec + 1min setting worked couple times and I noticed that computer doesn't hibernate when computer shut down(yes power settings is "if you press shut down button -> hibernate"). But manually connecting pwr pins, computer hibernates.

5) I tried using it as regulad power supply after factory reset but it didn't seems to work so well. Sometimes motherboard gets voltages and sometimes not... Usually taking off all power and cables work if you don't get voltages to motherboard.



I don't think that it's something wrong in my computer setup because it worked well couple times.

So now I'm finished with my story and if you don't understand something with my writing(I'm not fluent in english), ask me.
