Title: Someone with a G80-3000 who could make some measurements for me?
Post by: damorgue on Wed, 22 August 2012, 10:04:43

Does anyone know what colours go to which pins of the PS/2 in a G80-3000? I think I have the older version of the PCB. I always thought the colours of the PS/2 were standardized but apparently they aren't. Could someone open theirs?

Best would be if someone in here has one with the old version of the PCB and could give me this:

How are these pins connected to the PCB? There are 5 solderingpoints. Labeled from top to bottom A-E. Could someone give me something like

1-A
2-B
3-D
4-C
5-E
6-not used

That is just an example. Thanks. It would be greatly appreciated.

Opened mine up and used the multimeter on it.

plug - pcb
2 - 1 - white
3 - 2 - green
6 - 3 - yellow
4 - 4 - black
4 - 5 - black

my pcb has numbers the bottom is 1, that's what I've just put in this reply.  So I think for you 5 = A etc.

Hope that helps.

GREAT

thanks dirge, I have been trying to figure out which of the thick traces were ground and 5V and which of the thin ones were data and clock.

Edit:
I am going to add this here so that I can have both on the same screen as reference.

Pin 1    +DATA
Pin 2    Not connected
Pin 3    GND
Pin 4    Vcc
Pin 5    +CLK
Pin 6    Not connected

pin# - what it is supposed to do >>> pcb - colour of wire

pin2 - nothing >>> 1 - white
pin3 - GND >>> 2 - green
pin6 - nothing >>> 3 - yellow
pin4 - Vcc >>> 4 - black
pin4 - Vcc >>> 5 - black


Something seems a bit off here, data isn't used?

Perhaps the image is describing the socket and not the cable and as such it is mirrored? That makes much more sence.

That would make it:
pin1- data >>> 1 - white
pin4 - Vcc >>> 2 - green
pin5 - clock >>> 3 - yellow
pin3 - ground >>> 4 - black
pin3 - ground >>> 5 - black

Edit: dirge, can you confirm that you took the image above and numbered the pins as if the image was depicting the end of the cable?

Yes I took the image as if I was looking at the end of the plug. :)
