Security Features
Product is designed, manufactured and delivered in security-controlled
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. 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.
Secure Packaging
“Tear away” packaging ensures secure delivery of the Switch as it is
routed to the end user.

Step 3 – Connecting the Computers
3.1 Using USB cables, connect each computer to the USB port in
"computer interface ports" area on product.
3.2 If computer uses audio output, e.g. speakers/headphones, connect
audio cable from its audio output port to the corresponding audio
input port on product.
3.3 If the computer uses a smart card/CAC reader, connect a USB
cable between the CAC-enabled computer and the corresponding
CAC port on product.
Note:
1. If the number of product channels is larger than the number of
sources used, make sure the computers are connected in a row
starting from computer #1. For example, if there are 3 channels
used, connect computers to channels #1, #2 and then #3.
2. The USB cable must be connected directly to a free USB port
on the computer, with no USB hubs or other devices in between.
Step 4 – Powering Up the Computers
Power up all the attached computers and check for display
and peripheral functionality. All computers can be powered on
simultaneously.
Note: Your computers should recognize the Switch and automatically
install the HID USB driver if necessary.
When you power on your computers, the Switch emulates both a mouse
and keyboard on each port and allows your computers to boot normally.
The computer connected to port “1” will be displayed on the monitor.
Check to see that the keyboard, monitor, and mouse are working
normally. Proceed to do this with all occupied ports to verify that all
computers are connected and responding correctly. If you encounter
an error, check your cable connections for that computer and reboot.
If the problem persists, please refer to the Troubleshooting section in
this User Manual.

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.
Selecting a Computer Using Port Selectors
Now that you have connected your console and computers to the
Switch, it is ready for use. You can select which computer you wish to
control by pressing the corresponding port selector on the front of the
Switch. The LED number will illuminate to indicate which computer (or
port) is currently selected. It may take approximately 1 second for the
video signal to sync after switching ports. This is normal behavior and
is dependent on the display connected. This is normal operation and
ensures that proper synchronization is established between the monitor
and the connected computers.
Keyboard and mouse inputs can only be sent to the selected computer,
and video outputs can only be received from the selected computer. The
Switch also prevents any data transfer between connected computers,
ensuring the security of your computers.
Please note that the default port at power-up is port 1. In case of a
power failure or if the power is cycled, the Switch will default to port 1.
