Question High security labs KM switch K304e set up problems

[jeff776]

Hi
I recently purchased a KM switch k304e.
I would like to build my setup but i am struggling.

Here is my plan:
1. Computer No.1 with 2 screens, one next to each other (left to right).
2. Computer No.2 with 1 screen, above the 2 screens of computer No.1 (in the middle).

Thus far i tried to connect with the following steps:
1. Connect the KM switch to the power.
2. Connect the computer to the KM switch to the DPP plug of slot No.1.
3. Connect screen No.1 to computer 1 using DisplayPort.
4. Connect screen No.2 to computer 1 using DisplayPort.
5. Connect mouse to mouse usb slot in the KM switch.
6. Connect keyboard to keyboard usb slot in the KM switch.

Here i already came across a problem.
I could not move the mouse between screens that are connected to computer 1.

What is the next step to solve this problem?

Thanks for the help!

Best regards, Eitan.
