Overview
Main Features
Product is designed, manufactured and delivered in security-controlled
environments. Below is a summaty 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.
Metal enclosure is designed to resist mechanical tampering with all
microcontrollers protected against firmware-read, modification and rewrite.

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:
This is supported when single display is connected to Combiner. The Touch
Screen models supported are those manufactured by ELO, LG, Dell, Samsung
and Sharp.
•• 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.

Notes about display resolution setting:
•• The KVM combiner channel resolution, selected from the channel menu,
determines the size of the channel window. It will not affect the actual
resolution projected by the connected PC.
•• Models SC44HU-3 are capable to scale the image allowing the user to fit
more information on the same display size. Scaling is possible almost by
any factor and can be done using the mouse wheel.
Note: The best possible configuration to the KVM Combiner is when the
output display resolution (as set in system menu) and the channel resolution
(as set in the channel menu) are equal to the computer resolution.
When using two displays it is also recommended that both connected
displays will be identical.
•• Selection of resolution higher or lower than resolution range of connected
display may result image loss! In this case you can change display to
different type or restore factory defaults.
•• To restore factory default settings – use a paper clip or another sharp
object and press momentarily the recessed RFD switch located at the rear
side above the DC power jack.
•• See table in page 12 for supported output resolutions per model.

Operation
1. Self-Test Procedure
4. Front Panel Push-Buttons
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. Selftest failure will be indicated by the following abnormal LED behavior:
Following power up, the default channel is #1.
•• 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.
2. 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.
3. Product Mapping to Sources
Product mapping to sources is indicated by stickers/labels specifying which
channel is mapped to which computer.
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).
5. fUSB Port (applicable models)
The product is equipped with fUSB port enabling connectivity to external USBdevices 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.

Operation
•• When the USB device connected to the fUSB console port is qualified, the
fUSB status LED on the front panel would illuminate steady green.
–– 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.
–– 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.
HSL SC44HU-3 Secure KVM Combiner
6. 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.
7. 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.
8. 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.

VDT KM Mode
The Virtual Desktop Technology (VDT) KM mode is a unique mode developed
by integrating HSL unique KM technology to the KVM Combiner line. This
mode allows the user to switch active windows simply by dragging the mouse
from one window to another. In this mode the user can positions the channels
windows in any way he see fit and can switch between any adjacent windows by
dragging the mouse from one window to another.
This means that it will be impossible to point to the botton right corner with the
combiner mouse as long in VDT mode and without moving the windows.
Switching is done to mouse, keyboard, audio and fUSB.
When using the SC44HU-3 it is sometimes required to duplicate the display. In
Duplicate mode the Combiner functions as normal with one less displays than
actually connected when the highest connected displays duplicates display #1.
To enter into VDT mode use the CTRL, CTRL, F11, c. once in VDT mode it will
remain in that mode even when switching back and forth from System mode
to User mode. To switch out of VDT mode use the CTRL, CTRL, F11, b key
combination.
Switching will not be possible between channels which are not adjacent or over
lapping.
Duplicate Displays
To enter or exist duplicate mode use the CTRL, CTRL, F11, l key combination.
In VDT mode once two windows overlay one another switching will be done via
the boarders on the top window:

Preset buttons are useful to store user specific settings for specific job
environments.
It should be emphasized that preset stores only windows configuration. No other
settings or data is stored.
The selected window will maximize to its native input resolution.
To leave maximize mode – change back to system mode (by pressing the mouse
side buttons) and re arrange windows as needed.
Note: When using the SC44HU-3 it is possible to maximize a window from
directly from User mode. Pressing CTRL, CTRL, f will maximize the window in
which the user is working.
To save a setting the user should enter system mode and then click on one of
three preset buttons. As the save process starts the button will show a small
progress bar. After loading, clicking the preset button will load preset KVM
configuration.
Note: The presets will also save the scaling factor of the window if applicable..

In this example channel #1 was deactivated
Repeating this process will cancel this status and reactivate that channel.
Once a channel had been deactivated it would not participate in cyclic toggling
between windows and will not be displayed in anyway.
Tile function is designed to allow users to view and monitor all 4 channels. In
dual display mode, the tile function will place channels 1 and 2 windows on the
primary display and channels 3 and 4 windows at the secondary display. Each
source will be scaled by 50%.
For example, if the input source resolution is 1920 x 1080 the image displayed in the
source window will be 960 x 540. The size of the window is, as always; determined
by the output resolution (will be a quarter of the available screen area).

Scaling Function
Scale Mode
The SC44HU-3 include scaling function. The scaling function allows the user to
reduce or increase the size the source image without losing information enabling
him to see more of the sources on limited screen space. Scaling\Up scaling is
done by an advance scaling algorithm developed by High sec Labs.
By pressing the Scale button on the System Mode task bar or using the
CTRL, CTRL, s key combination the screen will be re-arranged as follow:
Channel 2
Scale a specific Window
Channel 1
From System mode it is possible to scale a specific window simply by pointing on
the active window, pressing the mouse side buttons and move the mouse wheel.
Channel 4
This will toggle the scaling of the active window between the different scaling
functions and no scaling keeping the actual window size fixed.
It is also possible to scale a window (both from system and User modes by using
the CTRL, CTRL, +/- key combination where pressing + will reduce the scaling
and the – will increase the scaling.
