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.

Display selection considerations
Display selection considerations
Proper selection of user display is critical for the success of deploying
KVM Combiners. The following is based on experience gained during
deployment of product:
• Avoid using old CRT displays.
• Some projects invest significant resources in overall project design
and implementation but neglect display and peripherals. Users may
reject product if proper displays are not used with it. As large LCD
costs are dropping it is more feasible to retrofit user desktop
completely.
• Proper size of display is critical. To enable simultaneous work with
several Windows, it is recommended to use LCD displays larger than
22” diagonal size.
• Considering user work area, try to use the largest display possible.
• It recommended to use displays that adjust automatically to
resolution changes. This is essential to support Window
maximization.
• Native resolution of display should match output resolutions of
product.
• Display should support Video input according to console video
port/s.To be future proof, it is preferable to have displays support
DVI/HDMI and
DP input.
• It is recommended to have the user involved in display selection
process during evaluation and initial deployment.

Operation
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, 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.
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 fUSB functions follow selected channel, unless Freeze
fUSB/Freeze Audio functions have been activated (see below for
details).
fUSB Port (applicable models)
The product is equipped with fUSB port enabling connectivity to
external USB-devices such as smartcard reader.
The filtered USB function (fUSB) enables to control which USB devices
will be operative when connected to product.
For more details on configuration options, please refer to the "fUSB
Configuration Manual".
Summary of rules that apply to fUSB 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 fUSB status LED
illuminating steady green.
3. The channel fUSB port on product is connected via USB cable
to a USB port on computer.
When the USB device connected to the fUSB console port is
qualified, the fUSB status LED on the front panel would
illuminate steady green.
o When connecting a USB device that is not qualified
or rejected for security reasons to the product's fUSB
port, the fUSB LED will flash green and USB device
will be inoperable. In such case the USB device must
be replaced with a qualified device.
27
Page 28
2/4 Ports Secure KVM Combiner User Manual
Section 5 - Troubleshooting
o When connecting a USB device to the product's fUSB
port that is undetectable for any reason (e.g. failed
device, non-standard device etc.), the fUSB 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,
fUSB functionality will move to computer #3 and be indicated
by channel #3 fUSB 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 fUSB" push button was pressed when fUSB
function was active on computer #1, for example, switching
to a different channel would keep fUSB function locked to
channel #1. To release "Freeze fUSB" function from channel
#1, the user will need to press again the "Freeze fUSB" push
button. The release will be indicated by the channel #1 fUSB
LED being turned off.
Restore-Factory-Default will release "Freeze fUSB" function
from any channel it is locked to.
Using "fUSB Freeze" feature
Press the "fUSB Freeze" push button to lock fUSB function to a
specific channel. The fUSB status LED will indicate that this option has
been activated and to which channel the fUSB 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.
Using "Audio Freeze" feature
Press "Freeze Audio" push button to lock audio to a specific channel.
The LED will indicate this option has been activated and to which
channel the Audio is locked to at the moment. This means that
switching channels would leave Audio active on current channel.
Restore-Factory-Default will release "Freeze Audio" function from
any channel it is locked to.
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.
