The HighSecLabs Secure KVM Switch is a device designed to simplify and secure the user experience when working with multiple computers. It allows for the secure sharing of keyboard, video, mouse, audio, and USB peripherals between several computers while maintaining the highest isolation between them. This obviates the need for purchasing and installing dedicated peripheral sets for each computer.
Function Description:
The KVM switch enables users to control multiple computers from a single set of peripherals. It supports various video interfaces including DVI-I, HDMI, and DisplayPort (DP), and offers models with 2, 4, or 8 ports. The device ensures secure isolation between connected computers, making it suitable for environments where data security is paramount.
The KVM's back panel is divided into "Console Ports" for shared peripherals and "Computer/Source Ports" for connecting individual computers. Peripherals such as the keyboard, mouse, audio devices, and USB peripherals are connected to the Console Ports. Each computer is then connected to a separate Computer Port group, ensuring that every computer has its own dedicated connection.
Switching between computers can be done by pressing the push buttons on the product's front panel, with the active channel indicated by an illuminated LED.

- Connect all peripherals and computers to the KVM.
- Power ON the KVM by plugging it into an AC wall outlet.
- Upon power-up, computer #1 is the default active channel, indicated by its front panel LED.
- Filtered USB Port (fUSB) Operation:
- The fUSB port is designed to accept only USB authentication devices (smart card/biometric readers) by default.
- A steady GREEN LED indicates a legitimate USB device is connected.
- A steady RED LED indicates a non-legitimate USB device is connected.
- When switching channels, the fUSB device automatically switches to the selected channel (indicated by the channel's fUSB LED turning steady GREEN).
- If switching to a channel without an fUSB connection, the fUSB port remains mapped to the last channel that had an fUSB connection.
- Freeze USB: A dedicated button on the front panel allows assigning the fUSB port to a specific computer, preventing it from switching with other peripherals. This is useful for devices like smart card readers that need to remain connected to a particular computer.
