IPGard SKMN-4S Overview

Designed for use in secure defense and intelligence applications, this SKMN-4S 4-Port USB KM Switch with Audio from IPGard features mechanical, electrical and optical signal isolation to prevent hacking and data leakage. It controls data relays using inverted signals, shielding connections from outside intrusion by forcing them to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to protect the switch's functions. The switch emulates the presence of a keyboard and a mouse for every attached computer through a USB cable, preventing direct connection between the peripherals and the connected computer.
