Using The Dkvm-2/4; Select Button - D-Link DKVM-2/4 User Manual

Using the DKVM-2/4

The DKVM-2/4 switch unit provides two ways to select
which computer is the active system. Use either the "Select"
button on the unit, or make use of the keyboard "Hot key"
commands.
You may notice that the mouse cannot be used for around 2
seconds when the DKVM-2/4 switches to another computer.
This is normal and is caused by synchronization that makes
sure the mouse operates properly.
