It features mechanical, electrical, and optical signal isolation to help prevent hacking and data leakage in environments where security is paramount. This switch supports resolutions up to 3840 x 2160 @ 60 Hz and features four input groups, each with two HDMI 2.0 ports for HDMI displays, one USB Type-B port for a keyboard/mouse, and one 3.5mm jack for stereo audio. There is also one output group with two HDMI 2.0 ports for dual displays, two USB 1.1 Type-A ports for a keyboard and mouse, and a 3.5mm stereo audio jack. Users can select which system they'd like to work with using buttons on the front panel, each of which has an LED indicator above to signal which input is in use.
