You've upgraded to HDMI output on the target box, but your KM or KN series switch is still expecting a direct connection. The KA7188 plugs into the HDMI port and two USB ports on the computer and hands you video up to 1920 x 1200, keyboard/mouse control, Virtual Media, and smart card/CAC reader access — all from one adapter. The built-in Audio De-Embedder pulls sound out of the HDMI signal so your console actually hears what the server is saying. Auto Signal Compensation handles the cable run distance for you. No DIP switch. Just plug in and go. Note: both USB connectors need to be seated in the target computer's USB ports for adequate power
