Security Features
The Belkin Secure DVI-I KVM Switch is the most advanced and
secure commercially available KVM Switch available today. Below is a
summary of all the security features incorporated into the Switch.
Dedicated Processors
The Switch features a dedicated processor per computer port. This
keeps each computer running on different security levels physically
separated and secure at all times, and prevents any unintended data
leakage between computers.
No Memory Buffer
The Switch does not have a memory buffer and does not have the
ability to store data. This prevents any keystrokes or other data
input from being unintentionally transferred as you switch between
computers, ensuring the integrity of your data.
Non-Reprogrammable Firmware
The Switch features custom firmware that is not reprogrammable,
preventing the ability to tamper with the KVM logic.
Unidirectional Data Paths
Optical diodes used in USB data paths provide high isolation and
prevent data leakage.
Solid-Aluminum, Uni-Body Enclosure
The one-piece aluminum enclosure reduces the entry points into
the Switch’s electronics and minimizes radiated signals that can be
snooped or intercepted.
Active Anti-Tamper Triggers
Active chassis anti-tamper triggers prevent KVM electronics from
being accessed and tampered with.
Tamper-Evident Tape
A holographic security tamper-evident label is placed on the
enclosure to provide a visual indication if the Switch has been opened
or compromised.
Tamper-Proof Hardware
All integrated circuits are soldered directly to the printed circuit board
to prevent tampering with the components.

Pre-Configuration
Where to place the Switch:
The enclosure of the Switch is designed for desktop or under-mount
configuration. An optional Mount Kit (Belkin part number F1D006) is
available.
Consider the following when deciding where to place the Switch:
• your proximity to the port selectors on the front of the Switch
• the lengths of the cables attached to your keyboard, monitor,
and mouse
• the location of your computers in relation to your console
• the lengths of the cables you use to connect your computers
to the Switch
Warning: Avoid placing cables near fluorescent lights,
air-conditioning equipment, or machines that create electrical noise
(e.g., vacuum cleaners).
Connection and Installation
Step 1 Connecting the Console to the Switch

computers, please ensure that all computer equipment and devices
are powered off.
Connect your monitor, keyboard, mouse, and speaker to the rear of the
Switch in the “User Console” section. (Refer to diagram on page 8.)
Step 2 Power Up
2.1 Power on the monitor.
2.2 Power up the KVM Switch by connecting the power. The display
diagnostic LED should be solid green a few seconds after
power up. This indicates the display EDID information has been
captured and secured. If the display diagnostic LED remains
blinking for longer than 10 seconds after power up, refer to the
Troubleshooting section of this user manual.

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, connect the computers
to a port on the rear of the KVM Switch. (Refer to diagram on
page 8.)

OPERATING THE KVM SWITCH
SECTIONSTable of Contents 123456784
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.

COMMON ACCESS CARD (CAC) CONFIGURATION AND INSTALLATION
SECTIONSTable of Contents 123456785
Step 1 Installation
1.1 Using the included 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.
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.”
Common Access Card (CAC) Configuration and
Operation (F1DN102C, F1DN104C models only)
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.
Notice: The CAC functionality was not certified by Common
Criteria. Currently, Common Criteria does not offer any guidelines
for CAC peripheral support in the Peripheral Sharing Protection
Profile. The inclusion of this functionality does not affect the
Common Criteria certification applied to the rest of the product.
