Belkin KVMs with CAC ports have a functionality called CAC Freeze. CAC Freeze is turned OFF by default, which allows the CAC port to switch between computers when the active channel is changed. Enabling CAC Freeze will set a static channel that the CAC will Freeze to even if the channel is changed.
1. With the SKVM power OFF, connect a device to the CAC port on the SKVM.
2. Connect a USB-A to USB-B cable between the computer and the USB-B port labeled CAC on the channel for that computer.
3. Power ON the SKVM and computer. Set the SKVM's active channel to the computer you wish to freeze the CAC to.
4. Quickly press and release the channel button for this computer 3 times to activate CAC Freeze for this channel. The CAC light on the front of the SKVM next to the channel button will illuminate to show the CAC is active on that channel.
5. Switch to another channel to ensure that CAC Freeze is active. The CAC device should not switch to any other channel.
Repeat steps 3 and 4 to disable CAC Freeze on that channel.
