Does this thing have a sata power plug for the HD?

From this image, the black plug looks like it. But i'm not too sure.

Thanks.

that pic clearly shows a SATA power connector in that harness.

the one I bought about a year ago had one. also like Toaster said, even if yours didn't come with one the adapters are very cheap.

Thanks. Just had to make sure.

The amp remote jumper (J6) is confusing. My amp only has 1 wire to for remote, yet the psu jumper has 2 wires... I checked the manual (RTFM, right?) and it states "left" wire goes to the amp, "right" to ground. I understand this for the most part. My question is simple. Which ground? Do I bolt this REM GND wire to my car's frame, or to the NEG/GND port on my amp?

Thanks!

it does not say that right goes to ground, it states "Right pin is GND". you don't need to connect anything to it. just hook up your amp's REM wire to the M2's "RMT" pin and leave the ground pin unconnected.

Im having a few problems with my M2-ATX.

1. When i turn off my car the power pulses and the computer does a hard restart, then 5 secs later will shut down, I have the jumper in position 1. I have tried swapping the IGN and POW lines but I know that is not the issues cause when i turn off the car the computer powers off instantly and when it comes back on i get a warning that the system didn't shutdown properly.

2. If I turn off the engine and leave ignition on after about 10 mins the amp turn on wire will have dropped to 5V's and my amps turn off The voltage is still 12.5V's across the battery and 12.3V's across the amp's, M2, and my distribution blocks

I swapped out the PIC controller for the one with the 1.4 firmware but that didn't seem to fix the problem. Could i maybe have gotten 2 bad controllers? or is my board bad or something else.

I am running the LCD and my HD radio from the 12v lines and 2 amps and a powered antenna from the amp line. All of my car power comes from a 8ga wire connected to a distribution block to 4ga wire to battery. All grounds go to 8ga to distribution block to 4ga to bare metal frame ground. With engine on i read 13.3V's across the amps and 13.5V's across the battery's.

Update: Finnally got a 13.8V AC/DC power supply and the M2 behaves properly. For other reason main power must be fluctuating.

For the life of me I cannot find any instructions to connect the lilliput to draw power from the M2.

Can someone point me in the right direction please.

yellow = +12v
black = ground

grab the car adapter, the center pin is the 12+(yellow) and the outside tabs are negative(black)

Seems this has caused at least half a dozen board failures already, most recently summarized here:

Very disappointed because of this...
Already bought (2) M2-ATX and apparently have damaged both of them due to this polarity issue on J9/J8 making that switch shorten and always powered. It's ridiculous since they don't properly mention this on the manual nor did they include +/- labels on the board, since when do you need to own a voltmeter to install a PSU???

On the 1st PSU the damage is clearly seen, on the 2nd I'm guessing its less obvious... Who is the manufacturer? I think this deserves out-of-warranty RMA.

Okay, i'm having a really hard time with the jumper settings. all the diagrams i see shows 4 rows a cross and 8 down but thats not what the board looks like. So can someone explain how to jump it so it is offdelay 5sec and hardoff 2 hours?

FirstAid · 03-09-2009, 09:02 AM

Just bridge the pins labelled with the letter B with a jumper.

escortguy · 03-09-2009, 02:20 PM

damn i tried it and it wont shut down.

anyone have issues with this with RFI?

Trying HD Radio and computer is causing a lot of RFI and destroys the FM signal. I'll be trying an AC PSU to see if there is a difference.
