ATEN ACS-1208A - Manual (Page 47)

F8 LOUT:
This function logs you out of OSD control of the computers, and
blanks the Console screen. After using this function you must log
in all over again to regain access to the OSD.
This is different from simply pressing [Esc] when you are at the
Main Screen to deactivate the OSD, where all you have to do to
reenter the OSD is tap the OSD Hotkey.
Note: 1. When you reenter the OSD after logging out, the screen
stays blank except for the OSD Main Screen. You must
input your password before you can continue.
2. If you reenter the OSD after logging out, and
immediately use [Esc] to deactivate the OSD without
having selected a port from the OSD menu, a Null Port
message displays on the screen. The OSD Hotkey will
bring up the Main OSD Screen.
