Step 4 Powering Up the Computers
Power up all the attached computers, and check for display
and peripheral functionality. All computers can be powered on
simultaneously.
Note: Your computers should recognize the Switch and automatically
install the HID USB driver if necessary.
When you power on your computers, the Switch emulates both a
mouse and keyboard on each port and allows your computers to
boot normally. The computer connected to port “1” will be displayed
on the monitor. Check to see that the keyboard, monitor, and mouse
are working normally. Proceed to do this with all occupied ports to
verify that all computers are connected and responding correctly.
If you encounter an error, check your cable connections for that
computer and reboot. If the problem persists, please refer to the
Troubleshooting section in this User Manual.
Step 3 Connecting Computers to the Switch
3.1 Make sure all computers are powered off.
3.2 Using the Belkin DVI/USB KVM Cable Kit (sold separately),
connect the computers to a port on the rear of the Belkin Secure
KVM.
Note: The Cable Kit must be connected directly to a free USB port on
your computer with no USB hubs or other devices in between.

OPERATING THE KVM SWITCH
Operation
Selecting a Computer Using Port Selectors
Now that you have connected your console and computers to the
Switch, it is ready for use. You can select which computer you wish
to control by pressing the corresponding port selector on the front of
the Switch. The LED number will illuminate to indicate which computer
(or port) is currently selected. It may take approximately 1 second for
the video signal to sync after switching ports. This is normal behavior
and is dependent on the display connected. This is normal operation
and ensures that proper synchronization is established between the
monitor and the connected computers.
Keyboard and mouse inputs can only be sent to the selected
computer, and video outputs can only be received from the selected
computer. The Switch also prevents any data transfer between
connected computers, ensuring the security of your computers.
Please note that the default port at power-up is port 1. In case
of a power failure or if the power is cycled, the Switch will
default to port 1.

17
COMMON ACCESS CARD (CAC) CONFIGURATION AND OPERATION
SECTIONSTable of Contents 123456785
Belkin® Advanced 4-port Secure DVI-I KVM Switch with DCU User Manual
Step 1 Installation
1.1 Using a USB cable, connect one end of the cable to the computer
that requires CAC, and the other end to the CAC port on the KVM
Switch that corresponds to the computer.
1.2 Enable CAC for the same port connection in Step 1.1 by switching
the CAC switch to the right.
1.3 Repeat steps above for additional computers that require CAC.
Note: Make sure that the CAC switch is disabled (left) for all other
non-connected CAC systems.
1.4 Once configured, the CAC connection will be switched only when
required by the connected computer. When switching from a CAC
enabled port to a non-CAC enabled port, the CAC connection will
remain with the last previously selected port where the CAC was
set to enable.
CAC connection to the computer requires a separate USB cable
connection and allows the user to specify whether there is a
CAC required for that computer or not. This allows the CAC to be
connected and controlled separately to the keyboard, mouse, video
and audio.
