Enable collection of bandwidth statisticsThe ALIF dual unit can record data transfer statistics from the System port and plot them on a graph for troubleshooting and optimization purposes. When you enable this option, you will first be presented with a pop up from which you can choose which aspects you would like to graph: Data throughput, various packet rates and/or frame rates. 
SubmitClick this button after ticking the above checkbox to plot the chosen statistics on a pop up graph.
Note:  Only the System port is measured. When the Teaming port is also used, the bandwidth will be shared equally so the figures shown for the System port will apply also to the Teaming port. For instance, if the graph shows 500Mbit bandwidth, then the total bandwidth will be 1 Gigabit.

APPENDIX B - The VNC port: Initial configuration
This section deals with the initial configuration of the VNC port of the ALIF 2112T unit. 
For details about the main System and Teaming ports, please see here. 
The default IP address of the VNC port is 192.168.1.42; it is possible to change this 
either through the VNC viewer or via the TX System Configuration page.  
Initial connection to the VNC port
Configuration of the VNC port section of the ALIF 2112T is carried out via a network, 
using a VNC Viewer program running on a computer or mobile device. VNC Viewers are 
available for most computers, tablets and smartphones.
• If you already have a VNC viewer, please follow the Initial configuration instructions 
given on the next page.
• If you do not already have a VNC viewer, there are three options:
• You can download a Windows VNC Viewer from the ALIF 2112T itself.
• You can download the latest VNC Viewers for most operating systems via the 
RealVNC website, or for tablets and smartphones from the appropriate app store.
• Without downloading anything, you can run a Java version of the VNC Viewer inside 
your web browser.
To download a Windows VNC Viewer from the ALIF 2112T unit
Note: The version of VNC supplied within the ALIF 2112T supports virtual media.
1 Connect the ALIF 2112T to an IP network where a suitable computer is available on 
the same subnet (please see the Installation chapter for connection details).

This option displays a mouse control dialog and is useful when the remote cursor is 
failing to respond correctly to your mouse movements, even after using the Resync 
mouse option. 
The mouse control dialog allows you to control the remote mouse cursor using a 
selection of buttons that you click with your local mouse. 
Controls
When clicked, this button reveals a menu of options 
concerned with keyboard, video and mouse operation.
Single Mouse Mode
This mode is for fast network connections where the cursor 
response is sufficient to provide instant visual feedback on 
the remote screen. When enabled, the cursor is ‘captured’ 
within the viewer window until you use the ‘escape’ hot keys.
To quit from single mouse mode, press F8 and then P. 
Alternatively, enable and use the mouse button escape 
sequences - see Advanced unit configuration for details.  
The single mouse mode does not require calibration. 
Resync Mouse
This option has the same effect as the  button on the menu bar and re-synchronizes 
the local and remote mouse pointers. 
Refresh Screen

Keyboard Control
This option displays a keyboard control dialog and is useful for sending keyboard 
combinations (to the host) that are needed regularly or that are trapped by the ALIF 
2112T.
When entering codes: 
+  means press down the key that follows
–  means release the key that follows
+–  means press down and release the key that follows
*  means wait 250ms (note: if a number immediately follows the asterisk, then    
the delay will equal the number, in milliseconds)
It is automatically assumed that all keys specified will be released at the end, so there is 
need to specify -Ctrl or -Alt if these keys are to be released together.
Examples:
‘Ctrl + Alt 12’ would be expressed as: +Ctrl+ Alt+1–1+2
+N means press the ‘N’ key
+Scroll means press the Scroll lock key
+Space means press the space key

Ignore DitheringDithering is a technique used by some graphics cards to improve perceived image quality by continuously slightly varying the color of each pixel. This gives the illusion of more shades of color than the display can really reproduce, and smooths the appearance of gradually shaded areas in images. Unfortunately, dithering is an issue for KVM extenders because it makes the image appear to be changing all the time even when it is static. This means that a great deal of unnecessary network data is sent to the VNC viewer, reducing the video frame rate and making mouse response appear slow.
The ‘Ignore Dithering’ option works by ignoring small variations in the video from frame to frame. This increases performance and reduces network traffic when the host computer is an Apple Mac or another computer that has dithered video output. It also improves performance if the video source is noisy (e.g. from a camera or a VGA-to-DVI converter). ‘Ignore Dithering’ is disabled by default to give full color accuracy and the best possible frame rate from non-dithered video sources.
Video settings
This option provides a range of options related to the video configuration.
Note: If using the Paste Clipboard feature, within the VNC viewer properties, ensure that in the 
Inputs section, the Share clipboard with server option is enabled. See Appendix  G for details.  
Video source Selects which video input to use. It is possible to display both single head screens (if connected) or select one over the other. If you are viewing Dual-Link video resolutions, only one head will be available.
Use Remote DDC Uses the DDC of the monitors connected to the ALIF Reciever. If this option is un-ticked you can select a DDC to use that is reported by the ALIF 2112T.
Hot Plug DetectWhen ticked, allows you to choose one of four hot plug detect periods when, after a display is connected, the DDC information is sought.
Threshold Adjusts the level of dithering noise that is ignored. The ‘Auto’ button attempts to choose a suitable value automatically, but the level can also be adjusted manually using the slider or arrow buttons. The best value is of course a compromise between capturing all the ‘real’ screen changes whilst ignoring the (almost invisible) dithering noise. A good way to choose the value is to watch the Display Activity indicator for a static screen. If the Threshold is too low, the Display Activity will be a high percentage while nothing is really changing. If the Threshold is too high, the Display Activity will be very low (or zero) but some real changes in the screen may be missed.

Virtual Media 
The Adder Virtual Media feature allows you to remotely make files available to a host 
computer that is linked to the ALIF 2112T. Disk drives, single files or collections of 
files and folders up to 2GB in size can be mounted via the VNC link, and appear as a 
read-only disk on the host. This can prove to be an invaluable tool when upgrading host 
computers from remote positions. 
Note: The file transfer is in one direction only, from viewer to host.
Note: Adder Virtual Media does not currently work with Apple Mac systems. 
In order to use the Adder Virtual Media feature, the VM link must be made between the 
ALIF 2112T and a USB port on the host computer. See USB link for details.
There are two main ways to use Adder Virtual Media: 
•  Create a read-only ‘virtual disk drive’ on the host from one or more files chosen at 
the viewer end. This is useful for copying one or more files from the computer running 
the VNC viewer to the host computer. See below.
•  Export a disk drive (e.g. CD, DVD or USB flash drive) from the viewer computer so 
it appears as a disk on the host attached to ALIF 2112T. A particular use for this is for 
booting or upgrading the remote host from a CD or other media that you have at the 
viewer end. See next page.
Remotely transferring files to the host as a virtual disk drive 
There are several methods of doing this. The easiest method depends on whether:
• The files are already on the clipboard of the viewer computer (following an Edit -> 
Copy operation). See To remotely transfer files from the clipboard >> 
 or 
• The files still need to be selected. See To select and remotely transfer files from the 
viewer computer >>
To remotely transfer files from the clipboard 
1 On the remote system, log into the ALIF 2112T using the VNC viewer. 
2  If not already done, use Windows Explorer to locate and copy the required file(s), or 
folder(s) to the clipboard. 
3 Within the VNC viewer window, click the Controls button and then select the Virtual 
Media option. A popup similar to the following will be displayed: 
 Click the Create VM Drive button to announce file availability to the host computer, 
whereupon a popup will confirm that the new virtual media disk is built. 
 Note: Remember, at this point the selected files/folders have not yet been transferred to the 
host system, they are just visible there. 
4  On the host computer (via the VNC viewer) locate the new virtual drive (shown as a 
Removable Disk) and copy the files to the required location on the host computer. 
To select and remotely transfer files from the viewer computer
1  On the remote system, log into the ALIF 2112T using the VNC viewer. 
2  Invoke the “Send Files” feature of the VNC viewer (called “File Transfer” in later 
versions), either by clicking the icon on the viewer’s toolbar or selecting from the F8 
menu. 
3  The viewer will display a window allowing you to select files or a whole folder. 
  Highlight the required files or folders (up to a maximum of 2GB) that you wish to 
transfer to the host computer and click the Open button. The new disk drive should 
appear on the host a few seconds later. 
 Note: The Use Entire Folder button provides a quick way to select a whole folder while you are 
viewing its contents.
 Note: Remember, at this point the selected files/folders have not yet been transferred to the 
host system, they are just visible there. 
4  On the host computer (via the VNC viewer) locate the new virtual drive (shown as a 
Removable Disk) and copy the files to the required location on the host computer. 
Note: When using Adder Virtual Media features, within the VNC viewer properties, ensure that 
in the Inputs section, the Share clipboard with server and the Enable file transfer options are 
enabled. See Appendix  G for details.
