HELPFUL SUPPORT FOR YOUR PS/2 MOUSE PORT

If you are needing to hook a PS/2 mouse port to your motherboard, there are a few things you need to know.  First off, how many pins are on the connector on your board?  Some of the more common are 5 pin, 6 pin, and 8 pin configurations.  They will look like this:

5 pins
6 pins
8 pins

 The manual that came with your motherboard will tell you the pin configuration or pinouts for your board.  Most companies have the pins on the board in different configurations.  Here is some examples.  The first one comes from PC Chips website.

Pin 1-->   .  .  <-- Pin 2
Pin 3-->      .  <-- Pin 4
Pin 5-->   .  .  <-- Pin 6
Pin 7-->   .  .  <-- Pin 8
1 - Mouse Clock
 2 - Ground
3 - Open
4 - Mouse Data
5 - Open
6 - Open
7 - Open
8 - V.C.C.

OR:

1.  Data
2.  Not Used
3.  Ground
4.  VCC
5.  Clock

Here is a couple of examples from Soyo USA's website:


 

Once you learn what the pinouts are, then you need to make sure the port is correct.
The port that is on the back of your computer needs to be setup as follows:

PS/2 MOUSE DIN ASSIGNMENTS
Pin  Name Dir Description
1 DATA ?? MOUSE Data
2 N/C  Not connected
3 GND ---- GROUND
4 VCC  ? Power , +5 VDC
5 CLK  ? MOUSE CLOCK
6 N/C  Not connected
If you need to move a wire, then take the connector in one hand, and use a sewing needle to gently push up the tab that holds the wire's metal clip in the connector.  Then gently tug on the wire and it should easily come out.  If not, then try to lift the tab a little higher so the metal clip will come out.
