Thank you for purchasing this Belkin Advanced Secure Keyboard/Mouse
(K/M) Switch. This KM Switch is designed for use in secure environments
across wide security gaps. This product provides the highest security
safeguards and features, meeting current and future cyber prevention
requirements.
This User Manual provides all the details you’ll need to install and operate
your new product, and also to troubleshoot it in the unlikely event of a
problem.
What is a KM (Keyboard / Mouse) Switch?
There are many cases where one user needs to work simultaneously with
more than one computer. In some cases users have multiple displays
attached to multiple computers. The challenge is how a single user can
interact with multiple computers with multiple displays each. KVMs are not
suitable for these users as they are designed to switch displays; allowing
the user to only see and manage one target device at a given time. Using the
Belkin Secure KM users can see all the connected computers at the same
time and easily decide on which computer he wants to work.
A KM switch is a device that switches a single keyboard and mouse between
multiple computers. A KM switch is essentially a KVM switch without the
video switching - all displays are continuously connected to their respective
computers; so that all connected device can be managed seamlessly, in
real time. Multiply displays can be connected to each computer that is
connected to the Belkin Secure KM. The Belkin Secure KM is designed
to have up to 8 computers connected and working simultaneously in any
possible monitor setup. The configuration of the Belkin Secure KM can be
done by using the KM presets or by using the easy to use configuration tool.
The Belkin Secure KM supports Windows, Linux and Mac operating
systems. Switching is done simply by dragging your mouse from one
window to another having it disappearing from one machine and appearing
on another. Multi Displays connected to the same computers are only
supported by Windows based operating systems.

Security Features
Product is designed, manufactured and delivered in security-controlled
environments. Below is a summary of the main advanced features
incorporated in product:
Advanced isolation between computers and shared peripherals
The emulations of keyboard, mouse and display EDID, prevent direct
contact between computers and shared peripherals. Product design
achieves maximal security by keeping the video path separate with
keyboard and mouse switched together, purging keyboard buffer when
switching channels. All these features contribute to strong isolation between
computer interfaces, maintained even when product is powered off.
Unidirectional data flow: USB, audio and video
Unique hardware architecture components prevent unauthorized data flow,
including:
• Optical unidirectional data flow diodes in the USB data path that
filtrate and reject unqualified USB devices;
• Secure analog audio diodes that prevent audio eavesdropping with
no support for microphone or any other audio-input device;
• Video path is kept separate from all other traffic, enforcing
unidirectional native video flow. EDID emulation is done at power up
and blocks all EDID/MCCS writes. For DisplayPort video, filtration of
AUX channel exists to reject unauthorized transactions.
Isolation of power domains
Complete isolation of power domains prevents signaling attacks.
Secure administrator access & log functions
Product incorporates secure administrator access and log functions to
provide auditable trail for all product security events, including battery
backup life for anti-tampering and log functions. Non-reprogrammable
firmware prevents the ability to tamper with product logic.
Always-on, active anti-tamper system
Active anti-tampering system prevents malicious insertion of hardware
implant such as wireless key-logger inside product enclosure. Any anti-
tampering attempt causes isolation of all computers and peripheral devices
rendering product inoperable and showing clear indications of tampering
event to user.
Holographic security tamper-evident labels are placed on the enclosure
to provide a clear visual indication if product has been opened or
compromised.
Metal enclosure is designed to resist mechanical tampering with all
microcontrollers protected against firmware-read, modification and rewrite.

is not supported to prevent analog leakages through audio ports.
Port Coloring
The included color chips can be inserted into each port-selector button.
Colors can be associated with an established network to facilitate port
identification and reduce user switching error.
Port Naming
The included network-name labels can be placed in the area underneath
the port-selector button to facilitate port identification and reduce user
switching error. Blank labels are also provided for network names that are
not listed on the included network-name labels.
Increased Reliability
Using a new, advanced anti-tampering battery with extremely low self-
discharge rate the life expectancy of the switch has been increased
dramatically to over 25 years.

What is Seamless Cursor Switching?
Seamless Cursor Switching (SCS) is implemented in Belkin Secure KMs to
enable seamless cursor and keyboard switching between multiple displays.
SCS allows to configure any desired multiple display configuration using
the same, or different size displays and resolutions. Simply move the
mouse cursor across neighboring displays to switch between connected
computers.
Refer to the example in the figure on the right. Assume that computer #1 is
connected to the left display, computer #2 is connected to the top display,
computer #3 is connected to the center bottom display and computer #4 is
connected to the display on the right side. In this example all four displays
are identical. SCS allows the user to move the mouse cursor across the four
displays while automatically switching the shared peripherals (keyboard,
mouse and audio) based on the current cursor location. For example, when
the user moves the cursor from the left display to the center bottom display,
the KM identifies the display border crossing between these two displays
and switches the keyboard and mouse to computer #3.
SCS is now further enhanced with the inclusion of pointing device drivers
to support dual, triple and up to 16 head computers. With this technology,
user workstations may be integrated with any combination of single, dual,
triple and quad head computers. SCS Configurator software enables to
easily configure any set of display sizes, resolutions, geometry and physical
arrangements.
