Operators can switch between servers using intuitive front-panel pushbuttons or keyboard hotkeys, while the on-screen display (OSD) provides a clear menu for port selection and configuration. RS-232 control enables integration into automated or remote management setups. The switch emulates keyboard and mouse for each connected computer, ensuring error-free booting and seamless operation.
