4-port, secure (PPs 4.0) dual-video DisplayPort KVM switch with MST, CAC and audio support 

4x dual-head DisplayPort computers to 4x HDMI extended-desktop screens; NIAP 4.0 certified 

CK4-PM204C secure DisplayPort KVM switch includes MST (multi-stream transport) technology which reduces the amount of cables needed to connect to a PC. This allows two separate HDMI Ultra-HD (4K @ 30Hz) video output signals to be generated from just a single DisplayPort (4K @ 60Hz) input connection.

CK4-PM204C is a secure DisplayPort 1.2a compliant device. CK4-PM204C can control 2 computers with dual DisplayPort connections each, while providing the ability to view their video in an extended-desktop on four HDMI monitors.

CK4-PM204C uses MST technology to extend each 4K@60Hz DisplayPort input (from the computer) to 2x 4K@30Hz HDMI displays. This allows a user to extend their desktop display to four screens.

CK4-PM204C acts as quad-head KVM switch even though it requires only two display connections per PC. Each PC will recognize four connected monitors, and the user is able to extend the desktop across the 4 monitors.

Why Secure KVM Switch?
Traditional non-secure KVM switches offer centralized control of multiple computers, but offer no absolute isolation between them. This exposes systems to the possibility of malicious damage and disruption, and acquisition of sensitive data from one computer to another.

Sekuryx's secure KVM switch is designed for use in secure defense and intelligence applications where sensitive data must be protected. The switch is NIAP PPs 4.0 certified and equipped with the highest security features that meet today's information assurance safe control standards. The switch prevents data leakage between computers that can run at different security levels, eliminating any potential cyber threat.

Each model is equipped with internal anti-tamper switches, which sense attempts to open the device enclosure. Once the system identifies such an attempt, all the front panel LEDs will flash rapidly and the unit will become useless by shutting off connection with all attached PCs and peripherals disabling any functionality. The unit's enclosure is also protected with a tamper-evident seal to provide a visual evidence if the unit has been opened.

Ultra-Secure KVM Switching
CK4-PM204C is a 4-port DisplayPort KVM switch with a dedicated CAC port and support for 4K (3840x2160 @ 30Hz) resolution video. CK4-PM204C allows users to control KVM (keyboard, video and mouse) operation on four computers with DisplayPort video. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount. The unit's controller has a special protection feature that prevents reprogramming or reading the firmware.

With CK4-PM204C, all data relays are controlled by inverted signals, shielding connections from outside intrusion by forcing them each to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch's functions. Better yet, CK4-PM204C offers the highest security when accessing classified and public networks over the Internet through these isolated connections. By isolating connections between networks, CK4-PM204C ensures no data is leaked between secure ports and the outside world.

CK4-PM204C has clearly marked front-panel buttons for controlling the devices, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than CK4-PM204C.

CAC Support
CK4-PM204C supports CAC devices such as smart-card and biometric readers, bolstering security when using the device. However, Sekuryx takes CAC security even further, allowing users to assign specific peripheral devices to CK4-PM204C's CAC port. Once a peripheral device has been registered by an authenticated admin, users can then switch the connection between that device and the PC's along with KVM switching.

Keyboard and Mouse Emulation
The secure KVM switch emulates (simulates) the presence of a keyboard and mouse for every attached computer through a USB cable. Both selected and non-selected computers maintain a constant connection with the unit's keyboard-mouse emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected peripherals during switching operations. Emulation of keyboard and mouse also prevents direct connection between the peripherals and the connected computers, shielding systems from potential vulnerabilities. Opto-isolators are used in the unit to keep USB data paths electrically isolated from each other, providing high isolation and preventing data leakage between ports.

Secure EDID Learn and Video Emulation
CK4-PM204C simulates a generic EDID as default, allowing it to operate most of the connected monitors. Both selected and non-selected computers maintain a constant connection with the unit's video and EDID emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected monitors during switching operations. Upon activating the KVM switch, the unit will quickly and automatically learn new EDID for specific monitors. The unit prevents unwanted and unsecure data from getting transmitted between the computers and the display.
