Introduction
WELCOME
Thank you for choosing the ADDERLink
™
INFINITY (aka ALIF) family of high capacity
digital extenders/switches. By encoding high quality video, audio and Hi-Speed USB data
into Internet Protocol (IP) messages, ALIF units offer exible ways to link peripherals and
systems via standard networks.
This guide covers the ALIF101T unit, a highly compact dongle which can be attached to
its host computer and transfer high quality video (single link DisplayPort
™
or HDMI
™
according to the chosen model) and Hi-Speed USB signals across your network.
One-to-one conguration
The simplest conguration links one RX unit to a single TX unit, either by a direct link or over much
greater distances via a high speed network.
ALIF and AIM
Where multiple ALIF units are used on a network, we have developed the
ADDERLink INFINITY Management (AIM) server to allow comprehensive and secure
central control of all transmitters, receivers and users.
One-to-many conguration
Using multicast techniques, an unlimited number
of receivers* can receive video and audio data
streams from a single TX unit.
* A maximum of thirteen concurrent USB inputs (via
multiple RX units) are permitted to a single TX unit.

When using an AIM server to congure ALIF units, it is vital that all ALIF units that
you wish to locate and control are set to their factory default settings. Otherwise
they will not be located by the AIM server. If necessary, perform a factory reset on
each ALIF unit.

Video link
Each ALIF101T unit is supplied with either a DisplayPort™or HDMI connector
(model dependant). Video signals at pixel clocks up to 300MHz (equivalent to a
maximum resolution of 2560 x 1600 at 60Hz) are permissible. Two channel digital
audio is also supported via the video connector.
To make a video link

Support for audio
The ALIF101T can derive its (digital) audio feed either from the USB connection or from
the video link (i.e. embedded audio within the DisplayPort/HDMI signal). In both cases,
the digital audio is converted to analog as it is transferred to the receiver(s), where it is
output via their 3.5mm jack(s). The two audio sources are controlled from the System
Conguration page of the internal utility (see page 15) as follows:
• When the EnableAudio-1 option is checked, the ALIF101T arranges a bi-directional
audio stream with the host computer via the USB connection.
• When the EnableAudio-2 option is checked, the EDID denition of the DisplayPort
or HDMI connection will be altered to permit a uni-directional audio stream via the
video output. This allows the use of embedded audio, even when the video display itself
does not support audio.

Network link
ALIF transmitters and receivers can either be connected directly to each other or via a
high speed network.
A single Gigabit Ethernet port is located on the front panel. For direct links via 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. The ALIF101T
unit has an auto-sensing capability on its network interfaces, so for direct point-to-point
connections, no ‘crossover’ Ethernet cable is required.
Please see Appendix D for important tips about networking ALIF units.
To link the ALIF101T unit
1 Connect a CAT 5, 5e, 6, or 7 cable to the Gigabit Ethernet socket on the front panel
of the ALIF101T unit.
2 Connect the other end of the cable either directly to an ALIF receiver or to a Gigabit
Ethernet switch, as appropriate.
3 [For connections via a network] repeat steps 1 and 2 for the other ALIF unit(s).

USB and power connections
The ALIF101T unit is designed to be as exible as possible. It can either operate using
an optional external power adapter (see page 3) or derive all of its power from its
two USB plugs. The main advantage offered by using an external power adapter is that it
allows the ALIF101T unit to be active before the host computer; thus allowing a remote
user to access the host’s initial boot up and access the BIOS menu, when required.
If powered by USB only, then both the black and red USB plugs need to be connected.
If powered by external power adapter, only the black Hi-Speed USB plug needs to be
connected, for signal purposes. Whenever, the external power adapter is attached and
operating, then power will be taken from it rather than the USB plugs. There is no
problem if the red USB plug remains connected while the power adapter is used.
This is summarized as follows:

INITIAL CONFIGURATION
ALIF units are designed to be as exible as possible and this principle extends also to
their conguration.
Direct linking
Where ALIF transmitters and receivers are directly linked to each other, very little
conguration 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 units are connected via networked links, you can either congure them
individually, or congure them collectively using an AIM server:
• Conguring 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 conguration utility on a computer
system linked to the same network as the ALIF units.
• Conguring ALIF units collectively - The ADDERLink INFINITY Management
(AIM) server allows you to congure, control and coordinate any number of ALIF
transmitters and receivers from a single application.
• IfyouareusingoneormoreALIF101Ttransmitterswithinaninstallationmanagedbyan
AIMserver,theAIMservermustberunningrmwareversion4.12orabove.
IMPORTANT: When using AIM to congure ALIF 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 AIM server. If necessary, perform a factory reset on each
ALIF unit.
Manual factory reset
A factory reset returns ALIF101T unit to its default conguration. You can perform
factory resets using the ADDERLink INFINITY browser-based conguration utility or
by using this direct manual method.
To perform a manual factory reset
1 Power on the ALIF101T 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 for roughly fteen seconds, until the
indicators turn blue (Note:alternatingred/greenindicationswilloccurduringthefteen
secondperiodwhilethebuttonisstillpressed).
3 Release the reset switch.
The indicators will remain blue for a short while (less than ten seconds) while
ALIF101T unit congures itself and should then change to green if all connections
are correct; or orange if one or more of the video, USB and/or network links are
missing.
NOTE: If you are performing a factory reset and intend to disconnect the power
immediately after the reset, you must wait at least 30 seconds after you have released the
reset button for it to complete the process.
Use a straightened-out paper
clip to press the reset button
for roughly 5 seconds

ADDERLink INFINITY browser-based conguration utility
The browser-based conguration utility within all TX and RX units requires a network
connection between the ALIF101T unit and a computer on the same network. The
conguration utility allows you to perform many important functions. Please see
Appendix B.
To connect a computer to access the conguration utility
1 Connect a CAT 5, 5e, 6, or 7 link cable to the network port on the front panel.
The port automatically congures itself, so no cross-over cable is required (but is
supported if you do use one).
2 Connect the other end of the link cable directly to the network port of your
computer.
To access the browser-based conguration utility
1 Temporarily connect the ALIF101T unit and your computer, as discussed left.
2 Run a web browser on your computer and enter the IP address of the ALIF101T unit:

PERFORMING AN UPGRADE
ALIF101T units are ash upgradeable using the method outlined here. However, for
larger installations we recommend that you use the ADDERLink INFINITY Manager
(AIM) to upgrade multiple ALIF units. When using the method below, the ALIF101T unit
will be upgraded in sequence.
IMPORTANT: Upgrades should be performed equally on transmitters and
receivers at the same time. Mixed rmware operation may cause issues.
WARNING: During the upgrade process, ensure that power is not
interrupted as this may leave ALIF101T unit in an inoperable state.
If the upgrade process is interrupted and fails, it may be necessary to switch to the
backup rmware image in order to regain operation. See left for details.
To upgrade a single ALIF101T unit via the network link
1 Download the latest upgrade le from the Adder Technology website.
2 Temporarily connect the ALIF101T unit and a computer via a network (see
ADDERLink INFINITY browser-based conguration utility section for details).
3 Run a web browser on your computer and enter the IP address of the ALIF101T unit
to be upgraded.
4 Click the Firmware Upgrade link. Within the Firmware Upgrade page, click the Choose
File button. In the subsequent le dialog, locate the downloaded upgrade le - check
that the le is correct for ALIF101T unit being upgraded. The le contains a single
image.
5 Click the Upgrade Now button. A progress bar will be displayed (however, if your
screen is connected to ALIF101T unit being upgraded then video may be interrupted)
and the status indicators on ALIF101T unit will ash while the upgrade is in progress.
6 The indicators should stop ashing after roughly two minutes, after which ALIF101T
unit will automatically reboot itself. The upgrade process is complete.
Finding the latest upgrade les
Firmware les for the ALIF101T units are available from the Support>Product
Downloads section of the Adder Technology website (www.adder.com).

RESTORING A BACKUP FIRMWARE IMAGE
The ALIF101T unit retains a backup image of the previous rmware version in order to
provide a fallback in case of any issues with the primary image. The backup image has no
video or USB functionality; once invoked, you will need to load an upgrade le using the
web interface or via an ADDERLink INFINITY Manager (AIM) to load a new primary
image - see Performing an upgrade (shown right).
To restore the backup rmware image
1 Power on the ALIF101T unit.
2 Use a narrow implement (e.g. a straightened-out paper clip) to press-and-hold the
recessed reset button for roughly ten seconds until the indicators ash green/red.
3 Release the reset switch.
The ALIF101T unit will switch to the backup rmware image. Once complete,
ALIF101T unit will then continually ash green/red.
4 Perform an upgrade to reinstate a fresh primary rmware image - see right.

Unit Name
Name details that you can alter to distinguish this unit from all others. The name entered here will be read by
AIM units (if used) for administration purposes.
Unit Description
Allows you to optionally add a description of the unit, such as its location. Useful when many ALIF units are being used.
System port
This section determines the IP Address, Netmask and Gateway details for the Gigabit Ethernet port located on
the front panel. The default IP address is 169.254.1.33 which is the zero cong IP address that allows ALIF101T
unit to work immediately in point-to-point mode. You are recommended to change this to an appropriate
address in the private IP range 192.168.xxx.xxx
The default netmask is 255.255.0.0. If you change the IP address to the private range, you are recommended to
change this to 255.255.255.0 The default gateway address is 0.0.0.0
Force Multicast
By default, the ALIF101T unit will use unicast transmission when only a single RX is connected. This would then
be upgraded to multicast when one or more other RX units are added. By ticking this option, the ALIF101T
unit will always use multicast. This option should be ticked for most installations as it provides the most efcient
way to deliver video and audio to multiple destinations.
Enable options
These checkboxes allow you to determine which peripheral options will be used: Video, digital audio and USB.
• When the EnableAudio-1 option is checked, the ALIF101T arranges a bi-directional audio stream with the host
computer via the USB connection.
• When the EnableAudio-2 option is checked, the EDID denition of the DisplayPort or HDMI connection will
be altered to permit a uni-directional audio stream via the video output. This allows the use of embedded
audio, even when the video display itself does not support audio.
Note:Itispossibleforbothoptionstobeenabledatthesametimewithoutissue.
Identify unit
When clicked, these buttons cause the top indicators to ash to assist with identifying the ALIF101T unit within
a rack.
• The Identify Unit (short) button ashes the indicators for ve seconds.
• The Identify Unit (long) button ashes the indicators for one hour but can be overridden by clicking the
Identify Unit (short) button.
Target Multicast Conguration

Video Conguration
Peak bandwidth limiter percentage
The ALIF101T unit will employ a ‘best effort’ strategy in sending video and other data over the IP network.
This means it will use as much of the available network bandwidth as necessary to achieve optimal data quality,
although typically the ALIF101T unit will use considerably less than the maximum available. In order to prevent
the ALIF101T unit from ‘hogging’ too much of the network capacity, you can reduce this setting to place a
tighter limit on the maximum bandwidth permissible to the ALIF101T unit. Range: 0 to 95%.
Background Refresh
The ALIF101T unit sends portions of the video image only when they change. In order to give the best user
experience, the ALIF101T unit also sends the whole video image, at a lower frame rate, in the background. The
Background Refresh parameter controls the rate at which this background image is sent. The default value is
‘every 32 frames’, meaning that a full frame is sent in the background every 32 frames. Reducing this to ‘every
64 frames’ or more will reduce the amount of bandwidth that the ALIF101T unit consumes. On a high-trafc
network this parameter should be reduced in this way to improve overall system performance. Options: every
32 frames, every 64 frames, every 128 frames, every 256 frames or disabled.
Enable Magic Eye
This feature, enabled as standard, aims to reduce the effect of dithering - a technique used by some graphics
cards to improve the perceived quality and color depth of images by diffusing or altering the color of pixels
between video frames. The Magic Eye feature increases the frame rate and eliminates unnecessary network
trafc by ignoring the color dithering where it occurs. If the video source is not noisy or dithered then you
can switch off Magic Eye to enable full color accuracy. Magic Eye mode can remain enabled without penalty for
video that does not have dither or noise.
Use Default DDC and Choose Default DDC
When the UseDefaultDDC option is unticked, ADDERLink INFINITY will use the EDID that is reported by
the monitor connected to the receiver unit. However, if you tick the UseDefaultDDC option, you can then
select from a range of preset video resolutions from the ChooseDefaultDDC drop down box. Once selected,
ALIF101T unit will report itself to prefer this video mode.
Enable Hot Plug Detect on change of display
When this option is ticked, every time the monitor is changed at the receiver unit, hot plug state changes are
sent to the graphics card of the PC attached to the ALIF101T unit as if a screen has just been attached.
Period of Hot Plug Detect signal
This is the length of time that the hot-plug detect signal is de-asserted. The default of 100ms is sufcient for the
majority of HDMI/DP++ graphics cards, however, a small minority may need to be given a longer a period.
Frame skipping percentage
Frame Skipping involves ‘missing out’ video frames between those captured by the ALIF101T unit. For video
sources that update only infrequently or for those that update very frequently but where high delity is not
required, frame skipping is a good strategy for reducing the overall bandwidth consumed by the system. Range: 0
to 100%.
Compression
Determines the (AFZ and AFZ+) compression method used for video transmission. Choices are:
• ‘Pixelperfect’ - only uses pixel perfect AFZ,
• ‘Adaptive’ - guarantees frame rate, builds to pixel perfect,
• ‘Smoothestvideo’ - forces the maximum compression, or
• ‘Advanced’ - allows you to choose a xed compression mode:
• ‘AFZonly(pixelperfect),
• ‘AFZ+Minimumcompression’,
• ‘AFZ+Middlecompression’, or
• ‘AFZ+Maximumcompression’.

USB Settings
Enable Dummy Boot Keyboard
When ticked, ALIF101T unit will report a virtual dummy boot keyboard to the attached PC to ensure that
a keyboard is always reported when the PC boots up. The dummy boot keyboard uses one of the 13 USB
endpoints, therefore if all 13 endpoints are required elsewhere for USB devices (or a KVM switch only supports
two HID devices) then it can be disabled by deselecting this option. See also ReservedPortRange below.
Disable Hi-Speed
This option allows you to force the system to run at the low/full USB speed of 12Mb/s, thus forcing USB 2.0 Hi-
Speed devices to adapt to the lower rate.
Hub Size
Using this option you can select whether ALIF101T unit should report itself as a 13 or a 7 port USB hub. Some
USB hosts are only able to support 7 port USB hubs. If this option is set to 7, then only 7 USB devices are
supported by the PC.
Reserved Port Range
For some devices, e.g. touch screens, you may wish to ensure that they are always reported to the same USB
port number so that the USB driver will always nd the device. This option allows you reserve up to 8 ports
for certain devices. At the RX unit, the devices are assigned to the reserved ports. If a port reservation is to be
applied, then the dummy boot keyboard should be disabled. The default value for this option is ‘0’, i.e. disabled.
Security
USB Encryption
This setting determines whether encryption should be applied to the USB data passed across the link. Note
that video data is never encrypted.
Control Encryption
This setting determines whether encryption should be applied to the control data passed across the link. The
“Prefer off” setting means that control encryption is enabled if the receiver at the other end of the link has
“always on” selected, otherwise it is disabled. Note:videodataisneverencrypted.
Secure web pages with password
When ticked, this option enables https security so that the conguration pages are only accessible to the admin
user with a password.
Change/conrm password
These options allow you to change the admin password for the system.
To get here
1 Connect your computer to the network port on the front panel.
2 Run a web browser and enter the IP address of the unit. If the address is
unknown, perform a manual factory reset to http://169.254.1.33
