Kramer Secured KVM Combiners

Interact with multiple computers presented on the same display at the same time using a single set of USB, audio, keyboard, video and mouse peripherals.

Secure by Design

HSL KVM Combiner switches are designed to meet with the security requirements demanded by government agencies, military, financial institutions and similar security sensitive customers.

Securely share peripherals across different security domains

Securely share peripherals between computers that belong to different security classification levels while keeping the highest possible data separation security.

Prevent information leaks

Obstacle threats derived from sharing and switching of vulnerable, untrusted or unauthorized peripheral devices. Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware
tampering by enforcing multilayered security mechanisms.

View and control multiple computers simultaneously

Present and work with up to 4 computers at the same time. Cascade combiners to view and control up to 16 (4x4) computers on a single or dual displays.

Filter USB Peripherals

Block unauthorized USB devices while allowing secure switching of smart card and biometric authentication devices between computers. Whitelist and blacklist specific USB devices based on VID/PID characteristics.

SC21H-3 is a secure 2-port 4K30 UHD HDMI KVM combiner. It enables users to share peripherals - keyboard, video, mouse, audio and USB - between two different security-level networks/computers while isolating all hosts and protecting against data leakage and malicious attacks through shared peripherals. Advanced multiviewer and scaling capabilities enable increased productivity in environments that require viewing and interacting with many computers simultaneously.

SC21H-3 provides the highest possible isolation between connected computers and is designed to meet the security requirements of government agencies, military, financial institutions, and similar security-sensitive customers.

Features

Secure by Design - Meets the security requirements demanded by government agencies, military, financial institutions, and similar security-sensitive customers.
Work Freely Without Compromising Security - Control classified and non-classified computers without compromising security.
Prevent Information Leaks - Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware tampering.
Filter USB Peripherals - Allow or block specific USB devices based on VID/PID characteristics.
Keyboard Lock Indication - Caps Lock, Num Lock, and Scroll Lock indication on front panel.
Native Touch Screen Support - Interact with all connected computers using touch screen gestures, with no need for additional drivers or software. Compatible with standard Microsoft™ Digitizer driver-based touch screens without internal hubs.
Flexible Display Layouts - Resize source scaling and aspect ratio to create tile, scale and custom display layouts. Supports duplication and extended display view modes.

SC21H-N is a 2-port 4K30 UHD HDMI KVM combiner. It enables users to share peripherals - keyboard, video, mouse, audio and USB - between two different networks/computers. Advanced multiviewer and scaling capabilities enable increased productivity in environments that require viewing and interacting with many computers simultaneously.

Features
Increase Work Efficiency - View content on one large screen instead of multiple small screens while saving desk area in space restricted environments.


Freeze Audio - Assign the audio port to a specific computer while switching the keyboard, video and mouse between other computers. Useful for scenarios where a user has to listen to audio originating from one computer while working on another computer.


Copy & Paste - Transfer text and files between all the computers that are connected to the KVM switch (no network connection is needed between parties). Use standard copy and paste keyboard key combinations (CTRL+C / CTRL+V) or context–menu commands.


Native Touch Screen Support - Interact with all connected computers using touch screen gestures, with no need for additional drivers or software. Compatible with standard Microsoft™ Digitizer driver–based touch screens without internal hubs.

SC42DHU-3 is a secure 4-port 4K30 UHD DVI-I to HDMI KVM combiner. It enables users to share peripherals - keyboard, video, mouse, audio and USB - between two different security-level networks/computers while isolating all hosts and protecting against data leakage and malicious attacks through shared peripherals.

It also enables assigning a USB port to a specific computer while switching other peripherals, such as when a USB smart card reader must remain mapped to a certain computer. Advanced multiviewer and scaling capabilities enable increased productivity in environments that require viewing and interacting with many computers simultaneously.

SC42DHU-3 provides the highest possible isolation between connected computers and is designed to meet the security requirements of government agencies, military, financial institutions, and similar security-sensitive customers.

Features
Secure by Design - Meets the security requirements demanded by government agencies, military, financial institutions, and similar security-sensitive customers.


4K30 UHD Resolution - Supports resolutions up to 3840×2160 @30Hz.


Work Freely Without Compromising Security - Control classified and non-classified computers without compromising security.


Prevent Information Leaks - Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware tampering.


Filter USB Peripherals - Allow or block specific USB devices based on VID/PID characteristics.


Biometric/Smart-Card Reader Support - Connect a smartcard/biometric reader to the secure port to support user authentication across multiple isolated computers.


Keyboard Lock Indication - Caps Lock, Num Lock, and Scroll Lock indication on front panel.


Native Touch Screen Support - Interact with all connected computers using touch screen gestures, with no need for additional drivers or software. Compatible with standard Microsoft™ Digitizer driver-based touch screens without internal hubs.
