Description

The SX82PHU-4T Secure Tempest 8×2 Mini-Matrix KVM switcher provides isolated multi-computer access for environments that require simultaneous multi-source display and strict peripheral separation. This unit lets operators view and control up to eight computers across two console displays while maintaining certified protection for peripherals and data channels. The design emphasizes secure switching and simultaneous presentation of multiple sources on dual displays.

Key features include dual console outputs via DP 1.2/HDMI 2.0 that support UHD 4K at 60Hz, simultaneous display of sources, and mouse-keyboard switching by moving the cursor between screens. The switcher supports secure peripheral USB handling via fUSB and is compliant with the NIAP Common Criteria PP4.0 PSD Protection Profile. The PHU-4T variant also carries TEMPEST-level considerations for environments requiring electromagnetic security.

Performance specifications deliver 3840×2160 at 60Hz on both input and output when connected via DP or HDMI connectors. The switch supports standard audio via 3.5 mm jacks and standard USB HID for keyboard and mouse. Power requirements are modest at 35W maximum with universal 100-240V AC input and an internal power supply.

Connectivity is flexible with a dual DP/HDMI connector per computer port and dual DP/HDMI console ports, plus USB Type A console HID ports and USB Type B computer HID ports. The unit offers fUSB Type A at the console and fUSB Type B at computers for secure peripheral switching. Supported operating systems include Windows, Linux, and Mac for broad interoperability.

Typical applications include control rooms where multiple live sources must be displayed continuously, meeting rooms where host and guest systems are shown simultaneously, and classified workspaces requiring strong isolation between machines and peripherals. The switcher supports real-time monitoring scenarios and collaborative presentation environments where multiple sources are presented at once. It is suitable wherever secure multi-source display and control are required.

Installation is straightforward using standard DP or HDMI cabling and USB HID connections for keyboard and mouse. The product ships in a rack-friendly chassis that is designed for long lifecycle support and 24/7 operation in controlled environments. Built-in compliance certifications and a two-year warranty provide further assurance of reliability and support for professional deployments.
