Inputs:
When set to ‘Enabled’, all primary options 
below are ticked. The ‘Disabled’ setting 
unticks all of the primary options (causing 
‘view-only mode’ where no control 
data may be sent to the ALIF 2112T. The 
‘Custom’ setting is shown if you choose 
your own combination of options.
Enable keyboard input
Allows keyboard data to be transferred to 
the ALIF  2112T.
Pass special keys directly to server
When ticked, ‘special’ keys (the Windows 
key, the Print Screen key, Alt+Tab, 
Alt+Escape and Ctrl+Escape) are passed 
directly to the ALIF 2112T rather than 
being interpreted locally. 
Enable mouse input
Allows mouse data to be transferred to 
the ALIF  2112T.
Enable 3-button mouse emulation
This feature allows you to use a 2-button mouse to emulate the middle button of a 
3-button mouse. When enabled, press the left and right mouse buttons simultaneously to 
create a middle button action. You are advised to generally use a 3-button mouse.
Rate-limit mouse move events
When ticked, this feature reduces the mouse movement information that is sent to the 
ALIF 2112T and host system. This is useful for slow connections and you will notice that 
the remote cursor will catch up with the local cursor roughly once every second.
Share clipboard with server
This permits the “Paste Clipboard” operation (see Keyboard control), and the “Create 
VM Drive” feature of Virtual Media (see Virtual Media).
Enable file transfer
This permits the “file transfer” method of Virtual Media (see Virtual Media).
Menu key
This feature allows you to select which function key is used to display the VNC viewer 
options menu. The menu key is the only way to exit from the full screen viewer mode.

APPENDIX H - VNC viewer window options
Click the VNC icon in the top left corner of the viewer window (or press F8) to display 
the window options: 
Standard window control items
Full screen
Expands the VNC viewer window to fill the whole screen with no 
visible window edges or toolbar. Press F8 to re-display this menu.
Single mouse mode (P)
Used for fast network connections where a second, “predictor” 
cursor is not required.
Ctrl, Alt, Send F8, Send Ctrl-Alt-Del
Sends the selected keypress(es) to the ALIF 2112T and host 
computer. This is necessary because certain keys and key 
combinations are trapped by the VNC viewer.
Refresh Screen
Requests data from the server for a complete redraw of the 
screen image, not just the items that change.
Virtual Media...
Allows files to be transferred from the remote computer to the 
host. See Virtual Media for details.
Send Files to Server...
Allows files to be transferred from the remote computer to the 
host. See Virtual Media for details.
New connection...
Displays the connection dialog so that you can log on to a 
different ALIF 2112T or VNC server location.
Options...
Displays the full range of connection options - see Appendix G 
for more details.

APPENDIX I - Java viewer options
When you are connecting to the ALIF 2112T using the Java viewer, a number of options 
are available. 
There are four options pages:
Encoding and colour level
Auto select
When ticked, this option will examine the speed of your connection to the ALIF 2112T 
and apply the most suitable encoding method. This option is suggested for the majority of 
installations.
Preferred encoding
There are three manually selectable encoding methods 
which are accessible when the Auto select option is 
unticked. 
• ZRLE – This is a highly compressed method that is 
best suited to slow modem connections.
• Hextile – This method offers better performance 
than the ZRLE when used over a high speed 
network because there is no need for the ALIF 
2112T to spend time highly compressing the data.
• Raw – This is a primitive, uncompressed method that is mainly used for technical 
support issues. You are recommended not to use this method. 
Colour level
The color level is fixed at Medium (256 colors) for almost all browsers.

APPENDIX J - The KVMADMIN utility
Particularly useful for complex ALIF 2112T configurations and the control of remote 
installations, KVMADMIN is a powerful administration tool.
KVMADMIN is based upon the established VNC viewer and uses the same security 
system. Rather than a graphical interface such as the standard viewer, KVMADMIN uses 
command line control to provide the following administration facilities:
• Discover and adjust the ALIF 2112T configuration, including host systems,
• Save and restore the ALIF 2112T configuration,
• Set user names and passwords,
• Download the event log,
The use of KVMADMIN is strictly limited to the ‘admin’ user and for security purposes it 
is not possible to retrieve user names or passwords from the ALIF 2112T.
To use KVMADMIN you require the IP address and admin password of the ALIF 2112T 
unit. The command line is as follows:
kvmadmin   []
where  is one of the following:
• -setconfig 
• -getconfig 
• -setusers 
• -getlog 
• -gethosts 
• -sethosts 
• -setmodes  
For instance, the command line:
kvmadmin -getconfig kvm1.cfg 192.168.2.1
... downloads the current configuration from the ALIF 2112T unit at the given address 
and stores it in the local file kvm1.cfg.
Whereas the command line:
kvmadmin -setusers users.csv 192.168.2.1
... configures the usernames and passwords for the same unit from the local file users.csv. 
For more information about KVMADMIN, please refer to the user notes supplied with 
the utility.

APPENDIX L - Hotkey sequences
ALIF 2112T allows you to enter commands suitable for any KVM switch in order to choose 
from up to 128 host systems. These switching commands can take the form of hotkey 
sequences that emulate standard keypress combinations.   
Hotkey sequences
Almost any combination of keypresses can be emulated using the following notations:
+ means press down the key that follows;
–    means release the key that follows
+– means press and then release the key that follows 
*    means add a delay. The standard delay period is 250ms, however, if a number 
immediately follows the asterisk, this will define an alternate delay period (in 
milliseconds)
Notes
• The entries are not case sensitive. 
• All characters can be entered using their ASCII codes, from 32 to 126 (i.e. A,B,C, … 1,2,3 
etc .) with the exception of the special characters above.
• It is not necessary to specify all keys to be released at the end because they are all released 
automatically after the last code.
• A number of KVM switches from alternative manufacturers use hot key sequences that begin 
with a press/release of either the Scroll Lock or Ctrl keys. These often require a delay between 
the initial key press and the channel number to allow the switch to respond. A 500ms delay is 
usually sufficient.
Examples 
To send the command Ctrl + Alt 4 you should use the following: +Ctrl+Alt+4. 
To send the command Ctrl + Alt 12 you should use the following: +Ctrl+ALT+–1+2  
(the ‘+–1’ entry causes the 1 key to be pressed and released before the 2 key is pressed).
To send the command Scroll lock 1 + Enter (with a 500ms delay) you should use the 
following:  +–Scr*500+1+Ent  
Main control keys (see ‘Using  abbreviations’)
Backspace | Ta b  | Return | Enter | Ctrl | Alt | Win | Shift | LShift | RShift  
LCtrl | RCtrl | LAlt | AltGr | RAlt | LWin | RWin | Menu | Escape | Space 
CapsLock | NumLock | PrintScreen | Scrolllock
Math operand keys (see ‘Using  abbreviations’)
Add (Plus) | Subtract (Minus) | Multiply

Insert | Delete | Home | End | PageUp | PageDown
Up | Down | Left | Right | Print | Pause

KP_0 to KP_9
Function keys
F1 | F2 | F3 | F4 | F5 | F6 | F7 | F8 | F9 | F10 | F11 | F12
Creating macro sequences
Hot key macro sequences can be up to 256 characters long. All keys are assumed to be 
released at the end of a line, however, you can also determine that a key is pressed and 
released within a sequence. Any of the following three examples will send a command 
that emulates and a press and release of the Scroll Lock key: 
+SCROLL-SCROLL 
+-SCROLL 
+SCROLL-
Example:
+-SCROLL+-SCROLL+1+ENTER
Press and release scroll twice, press 1 then enter then release all keys (equivalent 
definition is +SCROLL-SCROLL+SCROLL-SCROLL+1+ENTER-1-ENTER)
Using abbreviations
To reduce the length of the key definitions, any unique abbreviation for a key can be 
used. For example: “scroll”, “scr” and even “sc” all provide an identifiable match for 
“ScrollLock” whereas “en” could not be used because it might mean “Enter” or “End” 
(“ent” would be suitable for “Enter”). 
Note: Hotkey sequences and abbreviations are not case sensitive. 
For information about where to enter these codes, please see the sections Host 
configuration or Keyboard control.
