CYBEX™ SECURE USB FILTERS AND SC
USB PHYSICAL PORT BLOCK
SCUSBHIDFILTER/SCUSBCACFILTER/SCUSBPORTBLOCK
Quick Installation Guide
The Cybex™ Secure USB HID Filter
with eLock provides a secure
unidirectional connection of USB
keyboard and mouse.
The USB HID filter blocks all USB
signals other than standard
keyboards and mice. The secure
USB CAC filter blocks all USB
signals other than those configured
to be authorized. By default, the
CAC filter allows authentication
devices, such as smart card and
biometric readers.
The USB Physical Port Block with
eLock is a mechanical USB port
plug that physically locks individual
USB ports.
CAUTION: Once installed, the USB
filter and port block are
permanently attached to your USB
port and cannot be removed.
1. Installing the USB filter
If using an HID filter, connect a
keyboard or mouse to the filter.
Or, if using a configurable CAC
filter, connect an authorized
USB device to the filter.
Connect the filter to any USB
port on your computer.
The LEDs indicate an approved
device is connected and ready
for use. Each LED illuminates
solid green a few seconds after
power is applied.
• Red - no device detected
• Blinking - device is rejected
• Green - device is approved
NOTE: If two devices are
connected to the USB filter and
one is accepted and the other
is rejected, both LEDs will blink
and BOTH devices are blocked.
2. Installing the
USB port block
Connect a USB port block to
any remaining USB ports to
prevent unauthorized access.
