Need Pinouts for case wiring

Chaintech does not have the manual on their website. So does anyone know the which pins are what for the case wiring. The board itself does not indicate any of it.

I uploaded an image below. Can someone confirm if the pinout is correct for the 9CJS board. A few chaintech boards use the below configuration.


Possible Pinout For the 9CJS

I don't think the picture I posted now that I looked at the board is correct. One of the pins shown for the ide led is missing on the board.

I don't think I've recently seen a mobo without legends for the front panel connections. If not right next to the header then in some other location on the mobo where there is more open space to print. Get out your magnifying glass and look harder.

I believe I answered my problem. I just remember here at work a while back I built a pc that has a 754 socket chaintec board, so I look at it. It has the same pin count and the same missing pin. So guess it is safe to say this would be the same.

What I concluded is.

HD LED is pin 3 and 4
Speaker is pin 6 and 12
Reset is 14 and 16
Power LED is 5 and 9
Power Switch is 11 and 13

Same pin 15 is missing

Also I would like to say chaintec has really crappy support. Its been days and they never contacted me back. They don't have a single motherboard manual to download from their site for any of their motherboards. That is nuts.

OK, how about trial and error? Don't worry as you can't hurt anything until the board powers up and even then it is difficult.

First locate the power-on pins. Starting on the end opposite the missing pin, short pairs of pins until it powers up - use the power switch connector and put it on pairs of pins on the sides - lets number them even on one side and odd on the other - the header should at least have a mark denoting the pin 1 end - could be a white arrow pointing to pin one or a white line on or under the pin 1 end of the header

_ |_|_|_|_|_|_|_x_| In this diagram, usually 1-3 or 2-4 will be power-on and the other will

be reset.


try pins 1 and 3 first, then try 2 and 4 do not try cross-row options as the connections are almost always in the same row. As soon as you find the power up pins, go into the BIOS setup and set it to boot first from floppy or bootable CD (whichever you have handy). Put your bootable disk in and boot up from it so you can test the other pins. Generally, the reset button will be on the opposite row from the power pins. Try that first - locate the power LED prior to trying more pairs to locate the reset as that is the only one that should have power on it with a permanent ground pin two pins away (if you have a meter, it would make that easy - Sears has a nice kit on sale for $12. this wek - don't forget to buy the needed battery (usually 9V)). if no meter, just try each triplicate of pins with the power LED, first in one polarity - then the other. Usually that will be the pins on both sides of where the pin is missing. Usually the HDD LED will be on the other side on the end - will be hard to locate until you are doing something that accesses the HDD a lot - but you can put that off until then as it isn't that important. Generally the speaker positive side is always on (either 5 or 3.3V) and the beeps are controlled thru switching the speaker's ground pin on and off. So locate the pin with power on it and you're done. You get the gist. If you're lucky, somone may happen along who actually owns the board. But if not - you now have a Plan B...

FYI - Chaintech has been out of the mobo business for some time. .bh.

I do understand your procedure, and I do have a meter. But I believe I will try first the same pin configuration from the other chaintech board I looked at. It should be the same. I will post my results later.
