Belkin Secure SKVMs and SKMs allow users to utilize a single set of control devices and peripherals across multiple computer systems. Devices connecting to the KVM / KM are not communicating directly with each other; rather, they interface with the KVM / KM, which then handles the communication between them. The secure nature of the KVM / KM does require certain functionality blocked on keyboards, mice, and other control devices. Blocked functionality includes:
- Keyboards with built-in USB hubs
- Keyboards with built-in CAC readers
- Keyboards with multimedia controls
- Mice with multi-function buttons
- Keyboards and mice requiring special drivers
Some keyboard and mouse functionality is disabled due to the functional nature it requires. Devices with two-way communication, such as USB hubs, are fully blocked by the KVM / KM due to NIAP regulation requirements not allowing this functionality. Other items are required to be blocked by default for security reasons but can be enabled through the Administrator Configuration Terminal.
IMPORTANT: Before allowing any device to connect to your KVM / KM it is recommended to check with your IT and Security groups to ensure it does not violate any security policies. Belkin KVM / KMs are built and shipped following strict NIAP guidelines, with functionality turned off by default from the factory.
Using the Belkin HID Filter F1DN-FLTR-HID-4
Belkin Secure SKVMs and SKMs will work with standard keyboards and mice. Not all these devices are built the same, though, and contain additional hardware, representing themselves as non-standard input devices. The SKVM will block all functionality of these devices due to that. If you come across a Keyboard or Mouse that does not function correctly or at all with the SKVM, the Belkin TAA USB-A HID Fixed Filter, F1DN-FLTR-HID-4, may be of use. This adapter filters out the unwanted signaling of these devices, allowing their basic functionality to work.
IMPORTANT: Earlier versions of this device offered an additional security feature that, when connected, locks itself to the port it is connected to and cannot be removed. If you are utilizing this device for testing, it is recommended that you connect the adapter to a short USB extension cable rather than directly to your SKVM.
