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

Main Features
Product is designed, manufactured and delivered in securitycontrolled environments. Below is a summaty of the main advanced
features incorporated in product:
NIAP PPS Ver. 3.0 compliant
HSL 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. 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.
