SECURITY FEATURES
• USB Security
- Block unauthorized USB devices.
- USB authentication devices are authorize by default.
- Whitelist and blacklist specic USB devices based on VID/PID
characteristics.
• Video Security
- Computer video input interfaces are isolated through the use of
dierent electronic components, power and ground domains.
- The display is isolated by a dedicated, read- only, EDID emulation
for each computer.
- Access to the monitor’s Extended Display Identification Data
(EDID) is blocked.
- Access to the Monitor Control Command Set (MCCS commands)
is blocked.
• Keyboard & Mouse Security
- The keyboard and mouse are isolated by a dedicated, USB
device emulation for each computer.
- One-way, peripheral-to-computer data ow is enforced through
unidirectional optical data diodes.
- Communication from computer-to-keyboard/mouse is blocked.
- Non HID (Human Interface Device) data transaction is blocked.
• Audio Security
- Enforce computer-to-speaker, one-way ow of sound through
unidirectional optical data diodes.
- Prevent eavesdropping and line-in re-tasking by blocking
speaker-to-computer communication.
• Hardware Anti-Tampering
- Any attempt to open the product enclosure will activate an antitamper system making the product inoperable.
- Blinking LEDs provide a clear indication of a tampering event.
- Special holographic tampering evident labels on the product’s
enclosure provide a clear visual indication if the product has
been opened or compromised.
• Firmware Anti-Tampering
- There is no access to the product’s rmware or memory through
any port.
- Firmware is permanently stored on a non-reprogrammable
Read Only Memory (ROM) to prevent any modication.
- Firmware integrity is verified through a self-test procedure
during power-up. Upon detection of a critical failure the device
disables normal operation and provides the user with a clear
visual indication of failure.

OPERATIONAL HIGHLIGHTS
• Freeze USB
Assign the USB port to a specic computer
while switching the keyboard, video, mouse
and audio between other computers. Useful
for various scenarios, for instance, when a
USB smart card reader must remain mapped
to a certain computer.
• Freeze Audio
Assign the audio port to a specic computer
while switching the keyboard, video, mouse
and USB between other computers. Useful
for scenarios where a user has to listen to
audio originating from one computer while
working on another computer.
• Smoothly switch between computers
(Virtual Display Technology)
Automatically switch control from one
computer to another by dragging the mouse
cursor over the computer’s display border.
Peripherals switch to the next computer
without having to press any buttons once
the mouse is passing the display border.
• View applications in Ultra High
Denition (UHD) 4K video quality
Never compromise on video quality. Run
graphic-intensive, ultrahigh definition
applications on all single and dual monitor
KVM models.
• Avoid typing mistakes
Since two-way communication is blocked
by the KVM security, keyboard lock LEDs
do not function. Help users avoid typing
mistakes by visually indicating the status of
keyboard locks (CAPS-LOCK | NUM LOCK |
SCROLL LOCK) on the product’s front facing
panel.
• Native touch screen support
Interact with all the computers that are
connected to the KVM Combiner using
touch screen gestures. No need to install
any driver or software.
• Flexible screen layout
Resize source scaling and aspect ratio to
create Tile, Scale and Custom display layouts
that t user needs.
