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 headsets.
6. Product is equipped with an 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.
b. When connecting a non-qualified mouse, the mouse will be
non-functional with mouse cursor frozen on screen.
c. When connecting a non-qualified display, the video diagnostic
LED will flash green and video will not work.

Security Features
Product is designed, manufactured and delivered in security-controlled
environments. Below is a summary of the main advanced features
incorporated in product:
NIAP PPS Ver. 3.0 compliant
Product is designed from scratch to comply with latest NIAP PPS ver.
3.0 standard. Thoroughly tested, product meets international NIAP
security requirements and covers latest technologies:
• Optimized for USB (USB 1.1, 2.0, 3.0 and Type C) to support
newest peripherals;
• Optimized for HDMI and DisplayPort video;
• Enables newer protocols such as MHL to support mobile devices
and not only computers;
• Supports modern user interaction modes, such as cursor control,
touch-screen, multi-touch, and more.
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
at TEMPEST level 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.
