The Configure DPP (Dedicated Peripheral Port) option is available on Belkin SKVM units with a CAC card reader port. This option allows you to configure what devices are allowed through the CAC port on your SKVM. The SKVM is pre-programmed to allow CAC card reader devices only through this port. If you are having difficulties with using your CAC card reader through this port, this feature can help.

IMPORTANT: NIAP regulations prohibit specific devices from being used with a Secure SKVM. Your SKVM will block any devices, such as USB hubs, cameras, and data storage devices, from being used with it, even if you attempt to allow them to be used. The CAC port is a slow-speed USB 1.1 port intended only for security authentication devices. The status LED next to the CAC port will illuminate green for approved devices and red for blocked devices.
Option 1 - allow currently connected device on all channels
This will add the USB device currently connected to the SKVM's DPP (CAC) port to the allowed devices list. This is useful when troubleshooting authentication devices. This option will not allow you to add NIAP-blocked devices such as cameras, USB hubs, and storage devices. Even if you allow the device, the SKVM will still block it. The LED light next to the CAC port will light Green to show a device is connected and working or red to show a device is connected but not allowed.
This is an SKVM-wide change and will impact all channels of this SKVM.
Option 2 - block currently connected device on all channels
This will add the USB device currently connected to the SKVM's DPP (CAC) port to the blocked devices list. By default, the SKVM blocks all devices except CAC card readers. You can use this option to block a device you previously allowed but no longer want to be accessible through the CAC port.
This is an SKVM-wide change and will impact all channels of this SKVM.
Option 3 - show currently connected device
This will show the device ID data for the USB device currently connected to the CAC port. This data is helpful for device auditing and troubleshooting. Belkin support may ask for it when troubleshooting.
Option 4 - how currently approved device
This will display a list of all devices currently approved to be connected to and used with the SKVM CAC port. By default, CAC card readers are approved but are not shown on this list. This list will only show individual devices that an administrator has connected to the SKVM and allowed to work with the CAC port. The approved device does not need to be connected to the SKVM at the time of accessing this list.
Option 5 - show currently blocked device
This will display a list of all devices currently blocked from being used with the SKVM CAC port. By default, CAC card readers are approved but are not shown on this list. This list will only show individual devices an administrator has blocked on this SKVM CAC port.
Option 6 - reset dpp settings
This will reset any customizations made to the DPP (CAC) Port Blocked and Approved lists. It will also set the CAC port functionality back to the factory default, requiring you to manually add any devices other than CAC card readers that you wish to work with the CAC port.
This is not a factory restore and only impacts the DPP Blocked and Approved lists. Performing a factory restore will also reset all DPP settings.
Option 7 - upload dpp settings from a host
This option is under development and not functional at this time.
Option 8 - back
Takes you back one level on the Menu.
Option 9 - exit terminal
Choosing this will back your SKVM/SKM out of the Terminal mode, allowing you to use your SKVM as normal. However, this does not log you out of the administrator account you are currently logged into. To fully log out of the administrator account, disconnect power from the SKVM for 10 seconds to reboot it.
