SDMN-4S-P: Ultra-Secure KVM SwitchingMade In America

The SDMN-4S-P allows users to control KVM (Keyboard, Video and Mouse) operation on up to four computers with DVI displays (HDMI or VGA w/ adaptor). It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount.

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

The SDMN-4S-P has clearly 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 SDMN-4S-P.
