K304x-K308 Secure KM Switch User Manual
Introduction
Thank you for purchasing this HSL Secure KM Switch. This KM
Switch is designed for use in secure defense and intelligence
environments across wide security gaps. This 3rd Generation Secure
KM Switch offers optical data diode per channel. Optical data diodes
are used to prevent data transfer between connected computers
running at different security levels even if these computers
attempts to attack the KM. This product provides the highest
security safeguards and features that meet today’s and will meet
future cyber prevention requirements.
This User Manual provides all the details you’ll need to install and
operate your new product, in addition to troubleshooting
guidance—in the unlikely event of a problem.
What is KM?
There are many cases where one computer user needs to work
simultaneously with few computers. In some cases users are having
multiple displays attached to these multiple computers. The
challenge is how a single user can interact with multiple computers
having multiple displays. KVMs would not do a good job for these
users as they were designed to switch displays as well.
KM switch is a device that switches a single set of keyboard and
mouse between multiple computers. KM switch is essentially a KVM
switch without the video switching - all displays are continuously
connected to their respective computers.
Package Contents
Inside product packaging you will find the following:
• HSL Secure KM Switch unit
• 12V 1A wall-mounted power Supply (K304x only)
• AC power cable (K308 only)
• This User Manual
Important: This product is equipped with always-on active anti-
tampering system. Any attempt to open the product enclosure will
activate the anti-tamper triggers and render the unit inoperable.
If the unit’s enclosure appears disrupted or if all the channel-select
LEDs flash continuously, please remove product from service
immediately and contact HSL Technical Support.

K304x-K308 Secure KM Switch User Manual
Security Features
HSL Secure KM Switch is the most advanced and secure
commercially available KM available today. This product is a
derivative of high security KVM product used in newest NATO
nuclear submarines. Below is a summary of some of the security
features incorporated into the product.
Unidirectional Data Paths
Optical diodes used to enforce unidirectional data flow from the
peripheral devices to computers preventing potential leakage paths
between computers even in the severe threat of two infected
computers attacking the KM.
No Cross Cabled, No Shared Resources
No cabling connecting together computers. This product designed
to securely operate even when peripheral devices are vulnerable to
signaling attacks. The K304 does not allow computer access to any
shared resource and does not share controllable power sources.
Dedicated Processors for Emulation
The K300 product features a dedicated processor per computer port
to emulate peripheral devices. This keeps each computer running
on different security levels physically separated and secure at all
times, and prevents any unintended data leakage between
computers.
Non-Reprogrammable Firmware
The product features custom firmware that is not reprogrammable,
preventing the ability to remotely attack the KM control logic.
USB Ports Protection
Console USB ports are protected from the use of storage and other
unsafe USB devices through strong filtering (independent of
computer protection means). Unqualified devices are rejected when
connected to the product. Only mouse and keyboard data are
passed through.
Heavy-duty Steel Enclosure
HSL Secure KM Switch uses thick steel components to protect the
product from physical tampering and to minimize radiated
electromagnetic emissions that can be snooped or intercepted.
Active Always-On Anti-Tamper
Active chassis anti-tamper system prevents the KM electronic
circuitry from being accessed and tampered with by permanently
disabling the product once tampering is detected.
Holographic Tamper-Evident Labels
Four serially numbered holographic security tamper-evident labels
are placed on the enclosure surface to provide a visual indication if
the product has been opened or compromised.
Dedicated Peripheral Port (K304E only)
HSL patented Dedicated Peripheral Ports enables secure use of not
only CAC or smart-card readers but also fingerprint readers, face
recognition and iris recognition devices. Separate cables used for
this port enable further protection and isolation of this function.

Operational Features
The HSL Secure KM Switch was designed with the user in mind for
today’s IT environment. Below is a summary of some of the features
incorporated into the Product.
Virtual Display Technology (VDT)
VDT allows the K304 to switch automatically between computers
once mouse cursor crosses display borders. Seamless switching
between multiple computers with cusrsor movement.
Support for multiple head
Product can be easily configured to support dual, triple and up to 16
head computers through signed software driver. Note that single
head installation does not need any software installation.
Extensive administrator setup options
Administrator mode provides many customized settings from
display arrangement, size to cursor speed and acceleration.
Dedicate Peripheral Port (K304E only)
HSL K304E Secure KM Switch products supports parallel switching of
wide set of user authentication devices including CAC, smart-card
and biometric readers.
Dedicate Peripheral Port Host Detection and Freeze Functions
(K304E only)

K304x-K308 Secure KM Switch User Manual
What is Virtual Display Technology (VDT)?
Virtual Display Technology (VDT) is implemented in HSL K300 Secure
KM switches series to enable seamless cursor and keyboard
switching between multiple displays. VDT allows administrators to
configure any desired displays configuration with same or different
size and resolution. User simply moves mouse cursor across
neighboring displays to switch between connected computers.
Refer to the example in the figure at the right side. 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
at the right side. In this example all four displays are identical. VDT
allows the user to move the mouse cursor across the four displays
while automatically switch the shared peripherals based on the
current cusrsor location. For example when the user moves the
cursor from the left display to the center bottom display, the KM
identifies the display boarder crossing between these two displays
and switches the KM to computer #3.
HSL VDT 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 workstation may be integrated with any
combination of single, dual, triple and quad head computers.
VDT Configurator software enables the user administrator to easily
configure any set of display sizes, resolutions, geometry and
physical arrangements.

Product must be located in a secure and well protected
environment to prevent potential attacker access.
Consider the following when deciding where to place the Switch:
• User access to the front panel push-buttons is typically not
required as all user controls available through the mouse
and indications available on screen.
• Keyboard and mouse cables length. Cables typically may be
extended to a distance of 4 meters.
• Display cable length. Typically may be extended to around
10 meters without video quality degradation (still depends
on display and cables quality and must be tested prior to
fixed installation).
• The location of the computers in relation to the switch and
the length of available KM cables (typically 1.8 m)
Warning: Avoid placing cables near fluorescent lights, air-
conditioning equipment, RF equipment or machines that create
electrical noise (e.g., vacuum cleaners).

following steps:
• Connect each computer with a USB cable (CPN05493). For
additional details on cables see page 7. USB cable can be
connected to any free USB port in the computer.
Note: If the number of computers used is less than the number of
KM channels (4 / 8) connect the computers in proper order 1, 2 and
then 3.
Note: Note: The USB cable must be connected directly to a free USB
port on the computer, with no USB hubs or other devices in
between.
• Connect an audio cable (CPN05490) to the computer audio
output (lime green color) or line output (blue color) jacks.
Step 3 Power up
• Power up user display. Select through display setup menu DVI
input if applicable.
• K304x - Power up the Secure KM Switch by connecting the DC
power plug.
