Main Features
Product is designed, manufactured and delivered in securitycontrolled 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. Nonreprogrammable 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.

Operation
Operating Product
Self-Test Procedure:
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:
All channel-select LEDs will be turned ON and then OFF;
A specific, predefined LED combination will be turned ON;
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.
Now that product, computers and peripherals are connected and
powered up, it is ready for use.
Default Channel
After product boots up, blue LEDs stripe will illuminate and the
default active channel will be channel #1. This will be indicated by
white color illumination of
push-button #1.
Product Mapping to Sources
Product mapping to sources is indicated by stickers/labels specifying
which channel is mapped to which computer.
Front Panel Push-Buttons
Following power up, the default channel is #1.
The user can select any other channel by pressing the appropriate
front panel push button.
The mouse cursor will be positioned at the center of the selected
computer display. If computer is connected to multiple displays, the
cursor will be positioned at the center of the primary display.
The currently selected channel is indicated by white color
illumination of the appropriate push-button.
Once a different channel is selected – video, keyboard, mouse, audio
and DPP functions follow selected channel, unless Freeze DPP
function has been activated (see below for details).
DPP Port (applicable models)
The product is equipped with DPP port enabling connectivity to
external USB-devices such as smartcard reader.
The filtered USB function (DPP) enables to control which USB devices
will be operative when connected to product.
For more details on configuration options, please refer to the "DPP
Configuration Manual".
Summary of rules that apply to DPP switching:
It is assumed that a "connected channel" is when:
1. Product is powered ON
2. The USB device connected to product console is qualified
and ready for use, as indicated by the DPP status LED
illuminating steady green.
3. The channel DPP port on product is connected via USB cable
to a USB port on computer.
When the USB device connected to the DPP console port is
qualified, the DPP status LED on the front panel would
illuminate steady green.
21
8 and 16-PORT SECURE KVM USER MANUAL
Section 4 - Operation
o When connecting a USB device that is not qualified
or rejected for security reasons to the product's DPP
port, the DPP LED will flash green and USB device will
be inoperable. In such case the USB device must be
replaced with a qualified device.
o When connecting a USB device to the product's DPP
port that is undetectable for any reason (e.g. failed
device, non-standard device etc.), the DPP LED will
not illuminate at all and USB device will be
inoperable. In such case the USB device must be
replaced with a qualified device.
Since channel #1 is the default active channel after power up
and in case only some of the channels operate with a USB
device, it is recommended to make sure computer #1 is
connected to USB device.
Once the user switches channels, for example to channel #3,
DPP functionality will move to computer #3 and be indicated
by channel #3 DPP LED turning steady green.
In case user switches to a channel that is not connected to a
USB device, the previous USB connection will be terminated
and no new connection will be established.
In case "Freeze DPP" slider was moved to activate DPP
function for computer #1, for example, switching to a
different channel would keep DPP function locked to channel
#1. To release "Freeze DPP" function from channel #1, the
user will need to move the "Freeze DPP" slider again to its
original position. The release will be indicated by the channel
#1 DPP LED being turned off.
In case Restore-to-Default was performed while "Freeze
DPP" slider was activated on a specific channel, after boot up
this function will be locked to computer #1.
Using "DPP Freeze" feature
Move the "DPP Freeze" slider to lock DPP function to a specific
channel. The DPP status LED will indicate that this option has been
activated and to which channel the DPP function is locked to at the
moment. This means that switching channels would not affect the
processes performed by the USB device connected to that channel.
Keyboard Status Indication
In order to enhance usability, product provides keyboard status
indications via dedicated LEDs located on product front panel. To
maintain the required unidirectional connectivity between keyboard
and product, these indication are not given on the keyboard itself as
done with non-secure products
The keyboard status indications are given via 3 LEDs on the front
panel of the product:
• CL – CAPS Lock
• SL – SCROLL Lock
• NL – NUM Lock
The indications behave the same as the LEDs on the keyboard as if it
was connected directly to computer.
Switching from channel to channel may change the status of the
LEDs based on the current settings on the computer connected to
the active channel.
