 installations provide three methods to obtain instant access to any computer on your 

installation: Manual, OSD (on-screen display), and Hotkey.

Manual port selection simply involves pressing the port selection switch that corresponds to the device you wish to 

access.

Note: Before making your port selection, first make your console selection by pressing the appropriate console 

selection button.

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 requesting a username and password. You must provide a valid username and password 

to continue. After logging in with the default username and password, the OSD Main Screen opens in Administrator 

mode as below.  

Hotkey port control allows you to provide KVM focus to a particular computer directly from the keyboard.

All hotkey operations begin by invoking Hotkey mode. There are two possible keystroke sequences used to invoke 

Hotkey mode, though only one can be operational at any given time:

1. Hold down the Num Lock key;

2. Press and release the minus key;

3. Release the Num Lock key:

    [Num Lock] + [-]

1. Hold down the Ctrl key;

2. Press and release the F12 key;

3. Release the Ctrl key:

    [Ctrl] + [F12]

You can directly access any computer on the installation with a hotkey combination that specifies the port ID of the 

KVM port that a computer is connected to. To access a computer using hotkeys:

1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12] combination.

2. Key in the port ID.

3. Press [Enter]

After you press [Enter], the KVM focus switches to the designated computer and you automatically exit hotkey 

mode
