Plug the cable into the appropriate
CONSOLE port on the back of the switch.
Plug the USB or PS/2 keyboard and mouse
cables, audio (speaker/headset) cable and
Common Access Card (CAC) device into
the appropriate ports.
2Connecting computers to the switch
Make sure all computers are turned off.
Plug the speaker, keyboard and mouse
cables from the corresponding computer
into one of the ports on the switch. Repeat
for all computers.
NOTE: The cables must be connected directly
to an open USB port on your computer with no
USB hubs or other devices in between.

Turn the monitor on. Plug the power
supply cord into the switch. Plug the other
end of the power supply cord into an AC
wall outlet.The display diagnostic LED
should be solid green a few seconds after
power is applied.

Using a USB cable, connect one end of the
cable to the computer that requires CAC,
and the other end to the CAC port on the
switch that corresponds to the computer.
Enable CAC for the port connection by
switching the CAC switch to the right.
Repeat the previous CAC steps for
additional computers that require CAC.
NOTE: Make sure that the CAC switch is
disabled (switched left) for all other non-
connected CAC systems.
Once configured, the CAC connection will
be switched only when required by the
connected computer. When switching
from a CAC enabled port to a non-CAC
enabled port, the CAC connection will
remain with the last previously selected
port where CAC was enabled.
