User Guidance & Precautions
Please read the following User Guidance & Precautions carefully
before using the product:
1. As product powers-up it performs a self-test procedure. In
case of self- test failure for any reason, including jammed
buttons, the product will be Inoperable. Self-test failure will
be indicated by the following abnormal LED behavior:
a. All channel-select LEDs will be turned ON and
then OFF;
b. A specific, predefined LED combination will be
turned ON;
c. The predefined LED combination will indicate the
problem type (jammed buttons, firmware integrity).
Try to power cycle product. If problem persists please
contact your system administrator or technical support.
2. Product power-up and RFD behavior:
a. By default, after product power-up, the active
channel will be computer #1, indicated by the
applicable front panel push button LED lit.
b. Product Restore-to-Factory-Default (RFD) function is
available via a physical control button on rear panel.
Use a sharp object or paper clip to hold RFD button
pressed for several seconds to initiate an RFD action.
c. RFD action will be indicated by front panel LEDs
blinking all together.
d. When product boots after RFD, keyboard and mouse
will be mapped to the active channel #1 and default
settings will be restored, erasing all user-set
definitions.
3. The appropriate usage of peripherals (e.g. keyboard, mouse,
display, authentication device) is described in detail in this
User Manual's appropriate sections. Do not connect any
authentication device with an external power source to
product.
4. For security reasons products do not support wireless
keyboards and mice. In any case do not connect wireless
keyboard/mouse to product.
5. For security reasons products do not support
microphone/line-in audio input. In any case do not connect a
microphone to product audio output port, including

6. Product is equipped with always-on active anti-tampering
system. Any attempt to open product enclosure will activate
the anti-tamper system indicated by all channel-select LEDs
flashing continuously. In this case, product will be inoperable
and warranty void. If product enclosure appears disrupted or
if all channel-select LEDs flash continuously, please remove
product from service immediately and contact technical
support.
7. In case a connected device is rejected in the console port
group the user will have the following visual indications:
a. When connecting a non-qualified keyboard, the
keyboard will be non-functional with no visible
keyboard strokes on screen when using the
keyboard.

10. Important! Before re-allocating computers to channels, it is
mandatory to power cycle product, keeping it powered OFF
for more than 1 minute.
11. Product log access and administrator configuration options
are described in product Administrator Guide.
12. Authentication session will be terminated once product

Section 2 - Overview
Main 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.

Section 2 - Overview
Main Features (Cont.)
Metal enclosure is designed to resist mechanical tampering with all
microcontrollers protected against firmware-read, modification and
rewrite.
Filtered USB (DPP) feature (applicable models)
DPP feature enables to connect authorized USB devices to product.
Product is designed with complete isolation between DPP data, such
as user authentication smart card reader data, and all other product
traffic.
The DPP feature can be managed via Configurable Device Filtering
(CDF) mechanism with configuration permissions limited to
authenticated administrators. For more details please refer to the
"DPP Configuration Manual".
"Freeze DPP" feature
Dedicated "Freeze DPP" slider on front panel enables to lock this
function to a specific channel. When locked, switching channels will
not affect processes performed by the USB device connected to the
locked channel.
Cursor navigation: Virtual Display Technology (VDT)
VDT allows navigation between channels once mouse cursor crosses
display borders. This seamless switching enhances product usability
and ease of operation.
Support for multiple head
Product operating with computers connected to multiple-displays
requires installation of software driver on each multi-display
computer. Every product's channel can support up to 4 displays, e.g.
4-port-KM can support up to 16 displays.
System setup options & predefined presets
The KMs arrive with a predefined preset configuration for various
display positioning options.
For further customization of display positioning options and other
features, an easy-to-use tool is available

Tamper Evident Labels
Product uses holographic tamper evident labels to provide visual
indications in case of an enclosure intrusion attempt. When opening
product packaging inspect the tampering evident labels.
If for any reason one or more tamper-evident label is missing,
appears disrupted, or looks different than the example shown here,
please call Technical Support and avoid using that product.
Active Anti-Tampering System
Product is equipped with always-on active anti-tampering system. If
mechanical intrusion is detected by this system, the Product will be
permanently disabled and all LEDs will blink continuously.
If product indicates "tampered state" (all LEDs blinking) - please call
Technical Support and avoid using that product.
Product Enclosure Warning Label
Product has the following warning sticker on a prominent location
on the product enclosure:

Section 2 - Overview
What is Virtual Display Technology (VDT)
Virtual Display Technology (VDT) is implemented in EMERSON KM
switches to enable seamless mouse and keyboard switching between
multiple displays. With VDT, user simply moves mouse cursor across
neighboring displays to switch between connected computers.
VDT allows to configure any desired display positioning, including
displays with different sizes and resolutions.
VDT Configurator software enables to easily configure any set of
display sizes, resolutions, geometry and physical arrangement.
