Product Overview
Emerson® Cybex™ SC switches are field-proven, secure, KVM and KM switching solutions with
special support for government agencies. This switching system allows users to switch safely
between computers operating at different classification levels from a single set of peripherals,
providing continuous access to critical data. With multiple security features, the secure design
prevents the transfer of data between the connected computers, ensuring data security is not
compromised.
WARNING: This product is equipped with active intrusion protection and tamper-evident seals. Tampering
with the switch or breaking/removing the seals will permanently disable it and void the warranty. If the
enclosure appears to have been tampered with or if all the port LEDs flash continuously, please contact
Technical Support.
Features and Benefits
The SC switching system offers several options depending on the model:
•Support for HDMI, DVI-I and DisplayPort video
•Support for Common Access Card (CAC), USB biometric device and USB authentication
token
•Certification to Evaluation Assurance Level (EAL) 4+
•Support for USB and PS/2 keyboard and mouse
The SC switching system is also designed to provide additional layers of security, preventing
unintended data leaks between computers and providing additional USB port protection.
Feature Description
Complete network segmentation
Data flow is controlled and insulated from
peripheral devices using optical data
diodes. EDID emulators and internal
firewalls protect shared displays and
prevent external memory leaks.
Protection from shared resources
The switches are designed to securely
operate, even when peripheral devices are
vulnerable to signaling attacks. They do
not allow computer access to any shared
resource and do not share controllable
power sources.
Non-reprogrammable firmware Custom firmware is not reprogrammable
preventing the ability to remotely attack

Switching between computers
After turning on the switch, the default channel is channel one. You can select which computer to
operate using front panel push-buttons.
To switch between computers:
Select the computer by pressing the corresponding front panel push-button on the front of the
switch. The LED number will illuminate to indicate which computer is currently selected. It will take
approximately one second for the video signal to sync after switching computers.

CTRL | CTRL | F11 | - Mouse speed is decreased.
Dedicated Peripheral Port (DPP)
A DPP (enabled by default) allows secure use of CAC, smart-card readers, fingerprint readers,
face recognition and iris recognition devices. The host detection function of the DPP enables the
user to switch between ports without disconnecting the user authentication session, known as DPP
freeze. When locked, switching channels will not affect processes performed by the USB device
connected to the locked channel. If only one computer is using the DPP function, ensure that it is
connected to channel one.
NOTE: Do not connect a cable to the DPP if an authentication device is not needed. The switch will
automatically detect a cable and attempt to program the DPP selection logic. If you are connecting to the
DPP, your device must be fully compliant with a standard USB 1.1 or USB 2.0 and turned on.
Using DPP freeze
If you need to retain authentication information on one channel after switching to another, you can
freeze the DPP of the first channel.
To freeze the DPP channel:
1. Select the DPP channel you want to freeze.
2. On the front panel, switch the DPP freeze button.
3. Toggle to FREEZE mode. The channel indicator will illuminate on the selected channel and on
the FREEZE toggle.
NOTE: If you are on a channel that has a DPP enabled and you switch to a channel that is not using a DPP,
then you will lose the connection and the ability to freeze the information. You must switch back to a DPP-
enabled channel to reactivate the feature.
KM multi-monitor support
The SC KM145 switch is preconfigured to support one monitor per channel. The user can use the
preset keys to configure the KM to support more than one monitor per channel. To leverage the
multiple monitor feature, the user must install the multiple monitor driver on each of the desired
systems. When using the multiple monitor configuration, the user can experience seamless
switching by moving the mouse cursor to the desired display. To download the multi-monitor
display driver, visit www.Emerson.com.
The following images detail the different preset monitor configurations.
