Port Selection
KH1508A/ KH1516Ainstallations provide three methods to obtain instant access to any computer on your
installation: Manual, OSD (on-screen display), and Hotkey.
Manual
Manual port selection simply involves pressing the port selection switch that corresponds to the device you
wish to access.
OSD
The On Screen Display (OSD) is a menu driven method to handle computer control and switching
operations. All procedures start from the OSD Main Screen. To display the Main Screen, tap the OSD
hotkey twice. The default hotkey is [Scroll Lock]. You can change the hotkey to the Ctrl key or the Alt key
if you like.
The OSD incorporates a two level (administrator / user) password system.
Before the OSD Main Screen comes up, a login dialog box appears that asks
for a username and password. You must provide a valid username and password in order to continue.
If this is the first time that the OSD is being run, or if the password function has
not been set, simply press [Enter]. The OSD main screen displays in administrator mode. In this mode, you
have administrator privileges, with access to all administrator and user functions, and can set up operations
(including password authorization) as you like
When you invoke the OSD, a screen similar to the one below appears:
To bring the KVM focus to a port, double-click it, or move the highlight bar to it and then press [Enter].
Hotkey
Hotkeys allow you to conveniently provide KVM focus to a particular computer from the keyboard instead
of having to manually select them by pressing port selection switches, or accessing the OSD.
