SC42PHU−3 is a secure 4−port 4K30 UHD DP/HDMI 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. SC42PHU−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.

• 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.
• Freeze USB — Assign the USB port to a specific computer while switching the keyboard, video, mouse and audio between other computers. Useful for various scenarios, for instance, when a USB smart card reader must remain mapped to a certain computer.
• Smoothly switch between computers (Virtual Display Technology) — Automatically switch control from one computer to another by dragging the mouse cursor over the computer’s display border. Peripherals switch to the next computer without hav‌ing to press any buttons once the mouse is passing the display border.
• View applications in Ultra High Definition (UHD) 4K video quality — Never compromise on video quality. Run graphic–intensive, ultrahigh definition applications on all single and dual monitor KVM models.
• Avoid typing mistakes — Since two–way communication is blocked by the KVM security, keyboard lock LEDs do not function. Help users avoid typing mistakes by visually indicating the status of keyboard locks (CAPS–LOCK | NUM LOCK | SCROLL LOCK) on the product’s front facing panel.
• Native touch screen support — Interact with all the computers that are connected to the KVM Combiner using
  touch screen gestures. No need to install any driver or software.
• Flexible screen layout — Resize source scaling and aspect ratio to create Tile, Scale and Custom display layouts that fit user needs. Support screen duplication & extended screen view modes.
