DPMST-4S: Ultra-Secure KVM SwitchingMade In America

The DPMST-4S is a 2-port, dual-head DisplayPort Secure KVM switch that converts a single DisplayPort 1.2 input signal to two separate HDMI Output connections through advanced Multi-Stream Transport technology. This allows a user to extend their display and achieve resolutions of up to 4K (3840 x 2160 @ 30 Hz) on each connected monitor without from single DP port. The DPMST-4S is a Secure DisplayPort Standard Version 1.2a compliant device. The DPMST-4S can control up to 4 computers with single DP input connection each, and allows the support of two HDMI outputs in any combination. The DPMST-4S enables users to control KVM (Keyboard, Video and Mouse) operation on up to two computers with DisplayPort monitors. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount.

With the DPMST-4S, 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, the DPMST-4S offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the DPMST-4S ensures no data is leaked between secure ports and the outside world.

The DPMST-4S has marked front-panel buttons for controlling the device, so securely switching between sources is always simple. For high-grade, secure switching made easy, look no further than the DPMST-4S.
