Make sure you have to correct polarity on the switch header...it makes a diff on the M4.

ha I had already decided that if the rma'd one didnt work then that was my plan :) too bad it worked!
hello, i was hoping someone could help me out by explaining to me how to hook the M4 up so that it turns on either when i press the unlock button on my car remote or when the ignition is turned on. I tested my complete system with all the dip switches up in the off position where it acts as a normal psu and a normal power switch connected to the mobo. Ive been over the manual and it doesnt really explain how to hook up the ignition. I understand that the pins for the switch get connected to the mobo, but what sends the signal to the M4 to turn it on? thanks in advance i really appreciate any help given.
In the manual, the drawing on page 2, where it's indicating the middle terminal with "IGNITION"...well, wire in your ignition or accessory to that...
This, of course, is what turn it on.
Set dip1 on, the rest off...
Forget about trying to switch it on with the 'unlock' funtion...
Most people use an aux output on most remotes/alarms to power it up...
from my understanding of electronics, you need 2 points for a switch to work. Your telling me that i just take a wire from the ignition port and touch it to anything and itll work? since im putting the computer in my trunk, is there anything in the rear of hte c ar you can think of that i can link this to? how about if i want the computer to turn off when i turn the car off? i was going to run the + lead to the battery and ground the - lead anywhere. sorry but this is my first carpc and first time messing with an auto psu. the M4 manual leaves alot to be desired... and what do you mean by an aux output on the alarm? i am using my cars stock alarm system.
You need a constant ground and constant +
This is what the other terminals are for.
The middle 'ignition' terminal can't be just touched anywhere. I think your confused...
You MUST run a wire from the cars ACC at the ignition key switch to this center terminal on the M4.
When the M4 sense as current (i.e. when the car is on!) it switches on the PSU...
When you turn the car off, it senses this too, thru the IGN terminal, and shuts down your PC...
Read thru the manual a few more times...
The constant -ve is the second point for the switch... the IGN terminal is the +ve point for the switch... hope that helps.Quote:
