HighSecLabs K404F User Manual page 17

When you power up your computers, the product emulates display,
mouse and keyboard on each port and allows your computers to boot
normally. You should be able to move the mouse cursor on the
primary display connected to computer #1.
Check to see that the keyboard and mouse are working properly on
each computer.
Repeat this check 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.
DPP Installation
In case computer and product support DPP functionality, such as
user authentication smart card reader, do the following:
1. Connect USB device, such as smart card reader, to DPP port
on product console
2. Connect DPP input port on product to any free USB port on
computer using a USB cable.
Note: Do not connect the USB cable if DPP functionality is
not needed for that computer.
If only some of the computers use DPP functionality, such as user
authentication, make sure that computer #1 is connected to the USB
device. If needed, switch channels/computer mapping to create this
configuration.
When product is powered ON and connected USB device is qualified
and ready for use, the DPP status LED ("Freeze") will illuminate steady
green.

Secure Combiner KVM Switch User Manual
If the USB device is detected but not authorized, as not being a
Smart Card or CAC reader, it will be rejected for security reasons.
This will be indicated by DPP status LED illuminating steady red.
Note: If during installation as a result of bad output resolution
(resolution not supported by display) the video image on the user
display is lost it is possible to recover the device through the use of
Restore Factory Defaults switch (see item 17 in page 12). Pressing
this switch momentarily will return the Secure Combiner KVM to
the original production settings including lowest output resolution.
For information on how to reset the device to factory defaults see
the Troubleshooting section of this manual.
