The SDVN-4S allows users to control KVM (keyboard, video and mouse) operation on up to four computers with DVI, HDMI or VGA displays. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount.</p><p>With the SDVN-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 SDVN-4S offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the SDVN-4S ensures no data is leaked between secure ports and the outside world.</p><p>The SDVN-4S 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 SDVN-4S.</p>
