Cross-Control Software Setup

STEP 1 Research the Various Options

The easiest way to connect a single keyboard and mouse is through a software program. First, research a version compatible with your compters’ operating systems.

STEP 2 Download the Software

Once you’ve found the correct version, download the software and connect your primary computer.

STEP 3 Connect Secondary Computer

After connecting the first device, you’ll receive a code. Then, when you download the software on other computers, you can enter that code to add that computer to the cross-control system.

KVM Hardware Solution

STEP 1 Power Down Devices

Turn off your mouse, keyboard, and all monitors you plan to connect to the KVM switch.

STEP 2 Setup KVM Switch

Plug in the power adapter and the video cables. Then turn on your monitors and switch the KVM to port 1.

STEP 3 Connect Keyboard/Mouse/Computers

Plug in your devices to the USB slots available on the switch. Take two male-to-male USB connection cables, plug them into the two computers, and then connect them to the KVM switch.

STEP 4 Test Connectivity

Try moving your mouse pointer and using your keyboard to ensure the connection is successful.
