single ps2

[refosk]

I have a p55a-ud4 motherboard and I wonder is there some kind of hardware solution how to connect mouse and keyboard on single PS2 plug? Need it because I use KVM switch for two pc-s. Is it possible to rewire mouse and keyboard to that single PS2?

Hi and welcome to the Gigabyte Forum.

Good question and not one I have seen asked before.
 
Even though both mouse and keyyboard will work in the PS2 socket I don't think it would be possible for them both to work in the same socket at one time. I think it would cause confusion of which signal was being picked up by the computer.

I may be wrong and it might be worth asking GGTS for a confirmationm of this as they have more technical details than I can get hold of.

You can contact them here:

I found this pinouts http://www.networktechinc.com/technote.html and in fact rewire can be done because each component (mouse and keyboard) need +5, gnd, data and clock. So +5 and gnd are same for both, other 4 pins are used:  two for mouse (data, clock) and two for keyboard. If only I could get in my hands wiring pinouts for gigabyte motherboard PS2 conector. Can somebody help me with that? Than I can draw a solution for this problem.

Well it does look a little more hopeful then but I wouldn't hold your breath while waiting for the technical information from Gigabyte. I have asked for this type of thing for a long time but I am still waiting. Maybe you will have more luck than me.

Why not just get a PS2 splitter? http://www.amazon.com/gp/product/B000U64YLU/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0006IBBLS&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0AF4CZRMRZDZVX61SFPK

Nice one Bill. Sometimes the most obvious answers are right in front of us.

[refosk]

As you say "the most obvious answers are right in front of us", didn't think for that! I will try this simpliest solution. Thanks!

This solution doesn't work !!

[Dark Mantis]

Can you be a bit more concise please. When you say doesn't work what exactly do you mean...one works, neither works ?

Are you sure that both components work properly in the computer on their own?

[refosk]

Hi,
1. yes, keyboard and mouse works fine on another PC,
2. When connected as mentioned above the mouse is working but the keyboard is comletly dead!

I woluld be very happy if someone can explain how Gigabyte wired up this single PS/2 connector !! After all what is the joke to manufacter that kind of mobo?

[Dark Mantis]

Hi

Actually Gigabyte is not the only manufacturer to use this configuration.

When I asked about the keyboard and mouse working I did mean in this computer?
Can you try the keyboard in there and see if it works please?

Hi! Sorry to bump in.

The single PS2 on GA-H57M-USB3  Rev-2 works fine for keyboard but mouse is not detected on this port.

Thanks for your input yashoshah. That is more or less the opposite of what refosk seems to be reporting.
