VNC network link
The ALIF 2112T contains a VNC server that 
allows you to transmit a low-bandwidth 
version of the video output across standard 
networks to authorized remote viewers.
The VNC link can either be made over the 
same network as the main ALIF output or 
via a separate one. In either case, a separate 
VNC network port is located on the left 
side of the ALIF 2112T front panel for the 
purpose.    
To make a VNC link
1 Connect a CAT 5, 5e, 6, or 7 cable to the socket on the front panel of the ALIF unit. 
2 Connect the other end of the cable to an Ethernet switch.

Video link
ALIF dual units can simultaneously support 
up to two Single Link high resolution video 
displays at pixel clocks up to 165MHz; or 
can alternatively support a single Dual 
Link very high Resolution video display at 
pixel clocks up to 330MHz (equating to an 
example display mode of 2560 x 1600 at 60 
Hz refresh). 
To make a video link
1 Wherever possible, ensure that power is disconnected from the ALIF and the host 
computer.
2 Connect either one or two digital video link cables to the DVI-D socket(s) on the TX 
unit rear panel:
 Note: When using one very high resolution DVI-D dual link display, use a DVI-D 
Dual Link cable (such as the supplied Adder part: VSCD3) to connect the primary 
video port of the computer system to the DVI-D-1 connector of the ALIF dual. A 
dual link cable must also be used at the RX unit.

High speed links
ALIF dual (inc 2112T) units can be either connected directly to each other or via a high 
speed network. The connections can be copper-based Gigabit Ethernet as well as Fiber 
Channel over Ethernet (FCoE). These can be used in parallel to provide up to 2 Gigabit 
connections speeds.    
A single System port (Gigabit Ethernet) is provided as standard on the right side of the 
front panel. Additionally, the Teaming port, located just to the left, allows you to insert 
either an optional Fiber Channel SFP module or Active Copper SFP module. The chosen 
module can then allow either a fiber optic or additional Gigabit Ethernet link to be used 
in parallel with the fixed System (Gigabit Ethernet) port.       
Please see Appendix C for important tips about networking ALIF units.To link ALIF dual units using the Teaming port
2 Make your connection(s) between the chosen SFP module and either the other ALIF 
dual unit or a suitable network switch:
 Connect the transmit and receive 
fiber optic links to the sockets on 
the Fiber Channel SFP module. 
Then close the latch over the link 
connectors to lock them into place. 
Transmit and receive fiber links
Cable and fiber details
• For direct links over Ethernet cable, the length of cable should not exceed 100 
metres (328 feet). Network cables used for connections may be category 5, 5e, 6 or 7 
twisted-pair cable. ALIF 2112T units have an autosensing capability on their network 
interfaces, so for direct point-to-point connections, no ‘crossover’ Ethernet cable is 
required.
• For direct links via fiber, varying distances can be achieved depending on the module 
and cable types used. Please refer to the table in Appendix N for detailed information. 
The fiber links must have crossovers.
Optional Fiber Channel or Active Copper SFP module
To link ALIF dual units using the System port
1 Connect a CAT 5, 5e, 6, or 7 cable to the System port socket on the front panel of the 
ALIF dual unit. 
2 Connect the other end of the cable either to the other ALIF dual unit or to a Gigabit 
Ethernet switch, as appropriate.
3 [For connections via a network] repeat steps 1 and 2 for the other ALIF dual unit.  
1  Insert the appropriate optional SFP module 
(SFP-MM-LC, SFP-SM-LC or  
SFP-CATX-RJ45) into the aperture on 
the ALIF dual front panel:
 Connect a CAT 5, 5e, 6, or 7 cable

Configuration
The ALIF 2112T unit consists of two distinct sections (as detailed below) which each 
have their own separate configuration procedures within this chapter.   
The System and Teaming ports
These use either the Gigabit Ethernet or (optional) Fiber Channel 
over Ethernet (FCoE) module, on the right side of the front panel 
and provide high resolution DVI-D image, audio and peripheral feeds.
Please see page 15 for details.
The VNC port
Uses the standard Ethernet port on the left side of the front panel and 
provides lower-bandwidth image video feeds for use across standard 
networks and the wider Internet.
Please see Appendix B - The VNC port: Initial configuration for details.

SYSTEM AND TEAMING PORTS: INITIAL CONFIGURATION
ALIF 2112T units are designed to be as flexible as possible and this principle extends also 
to their configuration.
Direct linking
Where ALIF transmitters and receivers (all models) are directly linked to each other, 
very little configuration action is required, provided that they have their factory default 
settings in place. If the standard settings have been changed in a previous installation, you 
merely need to perform a factory reset on each unit. 
Networked linking
Where ALIF transmitters and receivers (all models) are connected via networked links, 
you can either configure them individually, or configure them collectively using an A.I.M. 
server: 
• Configuring networked ALIF units individually - You need to specify the 
network addresses of the ALIF units so that they can locate each other. This is done 
by running the AdderLink Infinity browser-based configuration utility on a computer 
system linked to the same network as the ALIF units.
• Configuring ALIF units collectively - The AdderLink Infinity Management 
(A.I.M.) server allows you to configure, control and coordinate any number of ALIF 
transmitters and receivers from a single application.
 IMPORTANT: When using A.I.M. to configure ALIF dual units, it is vital that all units 
that you wish to locate and control are set to their factory default settings. Otherwise 
they will not be located by the A.I.M. server. If necessary, perform a factory reset on 
each ALIF dual unit.     
Manual factory reset
A factory reset returns an ALIF transmitter or receiver unit to its default configuration. 
You can perform factory resets using the AdderLink Infinity browser-based 
configuration utility or by using this direct manual method. 
To perform a manual factory reset
1 Remove power from the ALIF unit.
2 Use a narrow implement (e.g. a straightened-out paper clip) to press-and-hold the 
recessed reset button on the front panel. With the reset button still pressed, re-
apply power to the unit and then release the reset button. 
 After roughly eight seconds, when the factory reset has completed, five of the front 
panel indicators will flash for a period of three seconds to indicate a successful reset 
operation.
Use a straightened-out paper clip to press the reset button while powering on the unit

AdderLink Infinity browser-based configuration utility
The browser-based configuration utility within all TX and RX units requires a network 
connection between the Gigabit Ethernet port of the ALIF 2112T unit and a computer 
on the same network. The configuration utility allows you to perform all of the following 
functions:
• View/edit the IP network address and netmask,
• Configure separate IP network addresses for video, audio and USB,
• Configure multicast settings (on RX units),
• Configure video bandwidth settings (on TX units),
• View the current video output (on TX units),
• Perform a firmware upgrade,
• Perform a factory reset,
• Enable/disable and configure the VNC network port settings.
To connect a computer system for browser-based configuration 
1 Connect a suitable network cable to the Gigabit Ethernet port on the right side of the 
ALIF 2112T front panel.
 Note: It is also possible to gain access to the browser-based utility via the Teaming port. 
2 Connect the other end of the link cable to your network.
3 Similarly, link your computer to the same network.
4 If not already switched on, power up your computer and the ALIF 2112T unit. You are 
now ready to use the browser-based configuration utility.
To access the browser-based configuration utility
1 Temporarily connect the ALIF 2112T unit and your computer, as discussed left.  
2 Run a web browser on your computer and enter the IP address of the ALIF dual port 
that you are using.
 The default settings are as follows: 
      ALIF 2112T RX units
 System port  169.254.1.33 169.254.1.32
 Teaming port  169.254.1.43 169.254.1.42
 Note: Where the port addresses of a unit have been changed and are not known, providing it 
is appropriate to do so, perform a manual factory reset to restore the default addresses.
 The opening page of the ALIF configuration utility should be displayed:

A rough guide to configuring TX and RX units
TX (transmitter) unit configuration
In an ALIF dual system, the majority of configuration settings are dictated by the RX 
units. Therefore, the local TX unit setup (using its browser-based configuration utility) is 
usually concerned only with three main factors: Its IP address details, the data streams 
to enable/disable and video signal optimization. Other TX unit pages, such as USB 
Settings, System Messages, Firmware Upgrades and Reboot are generally not used or 
altered during the majority of installations and are discussed elsewhere in this guide. See 
Appendix A for explanations of all TX configuration page options. 
Setting the TX address and output signal details
1 Display the TX unit System Configuration page.
2 Ensure that the IP address and netmask for the System port and the Teaming port (if 
used) are correct. The default settings of 169.254.1.33 and 169.254.1.43 for the two ports 
respectively are their zero config addresses - these are usually changed to some other 
address suitable for your installation. Indeed, the zero config address for the System port 
MUST be changed before the Teaming port can be used for network connections.
3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable 
Serial, if used) are enabled as appropriate. There are similar options within the RX 
unit configuration and it is important that the settings in both units are the same. If an 
option is ticked in one unit but unticked in the other, then that data stream will remain 
disabled. If you make a change, remember to click the Update Now button.
Optimizing the TX video signal
Note: Where the ALIF dual system is linked via two Gigabit links with sufficient available 
bandwidth, there should be no need to alter the default settings on this page. 
1 Display the TX unit System Configuration page and then change to the Video 
Configuration page.   
2 Make changes to the controls as necessary for each video port. There is no single 
combination of adjustments that will suit all installations, but generally:
• If moving video images are being shown frequently, then leave Frame Skipping at a 
low percentage and instead reduce the Peak Bandwidth Limiter and Colour Depth.
• Where screens are quite static, try increasing the Background Refresh interval and/or 
increasing the Frame skipping percentage setting.
 Make changes one at a time, in small steps, and view typical video images so that you 
can attribute positive or negative results to the appropriate control.
 See Video Configuration for individual explanations of the controls.
3 Click Update Now to apply each setting change.

RX (receiver) unit configuration
In an ALIF dual system, it is the RX unit (receiver) that determines where and how data 
signals are sent (and received) by the TX unit. Although numerous topologies (one-
to-one, one-to-many, many-to-one, etc.) are made possible by the ALIF system, they 
are all dependent on two underlying modes of operation: either Unicast or Multicast 
transmission. Where multicast transmission is not invoked for video and/or audio data, 
operation will be automatically served by unicast network transmission technologies. 
The RX unit setup (using the System Configuration page of its browser-based 
configuration utility) is concerned with four main factors: Its own IP address(es), the data 
streams to enable/disable, the IP address(es) of the TX unit and multicast transmission 
details. Other pages, such as USB Settings, System Messages, Firmware Upgrades and 
Reboot are generally not used or altered during the majority of installations. For further 
details about RX unit configuration pages, please see the AdderLink Infinity dual guide.  
Configuring the RX unit
1 Display the RX unit System Configuration page.
2 In the System Configuration section, ensure that the IP address and Netmask settings 
for the System and Teaming ports for this RX unit are correct. The default settings 
of 169.254.1.32 and 169.254.1.42 for the two ports respectively are their zero config 
addresses - these are usually changed to some other address suitable for your installation. 
Indeed, the zero config address for the System port MUST be changed before the 
Teaming port can be used. Enter the new values and click the Update Now button. 
The System IP Address that is set here will be sent to the TX unit as the destination 
for transmitted data (when operating in unicast mode). The Gateway entry is only 
necessary when the TX unit is located on a separate network to the RX unit.
3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable 
Serial, if used) are enabled (ticked) or disabled (unticked) as appropriate. There are 
similar options within the TX unit configuration; If one of these options is ticked in 
one unit but unticked in the other, then that data stream will remain disabled. If you 
make a change, click the Update Now button.
4 If necessary, alter the Audio Input Type to match your audio input. The line option is for 
a stereo line input, mic and mic boost are for mono microphones, the latter benefiting 
from a +20dB gain boost.
