The KVM Switch supports “Hot Plug“ function for easy addition or removal of PCs. The user
can arrange or maintain PCs as follows:
a. A PC can be disconnected and reconnected to the same or different port of the KVM
unit without having to power it off as long as it is not the Daisy-chain port or pass
through port.
b. The pass through port PC (i.e. The pass through port means the console port is
connected to PC directly) is powered on. Before you go hot plug function, please switch
to this pass through port to next port (or say emulation port ) and then switch back to the
pass through port.
c. You may unplug the mouse or the keyboard from the console port and plug it back in at
any time.

respective computer to avoid confusion.
2. The recommended VGA cable distance is 5 meters maximum without ghosting and

you need longer VGA cable, please use VGA extender (Model No. VGA-100, MAX.
100) to accomplish your applications.
3. The recommended PS2 cable distance is 5 meters maximum. Normally, the cable
length is based on driver capacity of your motherboard PS2 port. If you need longer
PS2 cable, please use PS2 extender ( Model No. PS-100, MAX. 100 feet) to
accomplish your applications.
4. The Power Jack polarity is center positive and the power adapter need be DC12V, 1A
or DC9V, 1A.
