WELCOME
Thank you for choosing the ADDERLink® INFINITY 1100 and INFINITY 2100 (aka ALIF1100 and ALIF2100) high performance extenders.The range offers dual-head video, audio and USB delivered over fiber and/or CATx connections. Pixel- perfect color, accurate picture quality at up to 2560×1600@60Hz and USB2.0 with fast switching.
Product in brief · Support for dual link speeds up to 1GbE using either CATx and/or fiber. Several model
variants available:
· ALIF1102 models have a fixed 1GbE CATx port plus an SFP socket for additional CATx or fiber.They also have a single DisplayPortTM video connector,
· ALIF1104 transmitters have a fixed 1GbE CATx port plus an SFP socket for additional CATx or fiber.They also have a single HDMI® video connectors,
· ALIF2102 models have a fixed 1GbE CATx port plus an SFP socket for additional CATx or fiber.They also have two DisplayPortTM video connectors,
· ALIF2122 models have two SFP sockets for CATx or fiber.They also have two DisplayPortTM video connectors,
· ALIF2124 transmitters have two SFP sockets for CATx or fiber.They also have two HDMI® video connectors.
· Transmitter and receivers from the ALIF2102, ALIF2122 and ALIF2024 variants can be freely mixed as necessary with the use of appropriate SFP modules,
· Support for 1x 2560×1600@60Hz or 2x 1920×1200@60Hz (ALIF2100 models only),

· Uni-directional analog audio (with combined headset jack on the receiver),
· Adder’s USB True Emulation for fast switching,
· Support for advance diagnostic and troubleshooting tools,
· Backwards compatibility with existing ALIF range,
· Plug and play.

Linking
ALIF1100 and ALIF2100 units can be linked in two mains ways: Direct or Networked.
Direct linking Where transmitters and receivers are directly linked to each other, very little configuration action is required, provided that they both have their factory default settings in place – just link them together. If the standard settings have been changed in a previous installation, you merely need to perform a manual factory reset on each unit.
Networked linking Where units are connected via networked links, you can either configure them individually, or configure them collectively using an AIM server: · Configuring networked ALIF units individually – In the absence of an AIM server,
unallocated units have the ability to locate each other.You can alter settings via the OSD on the console connected to the RX unit by pressing CTRL + ALT + C. · Configuring networked ALIF units collectively – The ADDERLink® INFINITY Management (AIM) server allows you to configure, control and coordinate any number of ALIF transmitters and receivers from a single application.
Note: If you are using one or more transmitters within an installation managed by an AIM server, the AIM server must be running firmware version 5.3 or above.

Safety
Please refer to the safety booklet provided in the box before use of this product.

IMPORTANT:When using AIM to configure 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 manual factory reset on each ALIF unit.

INSTALLATION

LOCAL FEED THROUGH
ALIF receiver units can be configured to support a local link to a separate host PC, via a dedicated ALIF transmitter, in addition to the main link to the network.The locally linked PC remains completely isolated from the main network. To configure this arrangement, ensure that the receiver is using its default IP address and is directly connected to the transmitter.The transmitter must use its primary network port, which is the interface using 169.254.1.33 as its default address, and be configured to either “Auto” or “Allow” for insecure connections (see “Insecure connections” on page 44).The easiest way to do this is to use a factory new or factory reset transmitter, you can then change any additional settings after connecting it to the receiver. Notes: For the local feed through feature to operate, the AIM server must be at version 4.8 or greater while the endpoints must be at version 4.0 or greater.The TX must use its primary network port and be in it’s default configuration, which can be achieved via a new unit or a factory refresh, when connected to the RX.
ALIF2122 RX

Note: ALIF1102 RX units support a single display.

TX/RX high speed links
ALIF2100 and ALIF1100 units can be either connected directly to each other or via a high speed (up to 1GbE) network. Links can be made: · Using the in-built CATx ports on ALIF2102,ALIF1102 & ALIF1104 models (see below), · Using additional CATx connections within the SFP ports (see next page), · Using the SFP ports with optional fiber (FCoE) modules (see next page).
Teaming ALIF2100 and ALIF1100 units are ready to automatically invoke teaming whenever the CATx and SFP (with either CATx or fiber modules installed) ports are both used to link transmitters and receivers.Teaming potentially doubles the available bandwidth for video intensive applications and also provides redundancy in case one link is lost.

Optional SFP module types · SFP-CATX-RJ45 for use with CAT5e (and above) cable. · SFP-SM-LC modules require OS1 or OS2 single mode fiber. · SFP-MM-LC modules require OM1, OM2, OM3 or OM4 multi-mode fiber. See Appendix E for further details about SFP modules and cable lengths.

To link using the in-built CATx port
(ALIF2102, ALIF1102 & ALIF1104
models only) 1 Insert a suitable CATx cable into the
RJ45 port on the front panel of the TX unit.

Start of Life:AIM or Point to Point configuration
To streamline initial configuration processes, all ALIF units employ a Start of Life (SoL) procedure when they are in an unconfigured state; either because they are new or because they have undergone a factory reset.
When an unconfigured ALIF unit boots, its SoL procedure will guide it to automatically determine which of two modes it should adopt:
· AIM mode – place itself into the control of a specific AIM server on the network, whereupon the ALIF will be assigned suitable configuration details to fit within the network of similar units.
· Mini Matrix (P2P) mode – place itself into Mini Matrix (Point to Point) mode to allow manual configuration of links with other ALIF units.
The SoL procedure follows this basic logic flow to determine the correct mode:

PERFORMING A MANUAL FACTORY RESET
A factory reset returns ALIF unit to its default configuration.
To perform a manual factory reset 1 Power on the ALIF unit.
2 Use a long narrow implement (e.g. a straightened-out paper clip) to press- andhold the recessed reset button on the front panel for roughly ten seconds, until the status indicator turns blue (Note: alternating red/green indications will occur during the ten second period while the button is still pressed).
3 Release the reset switch.The indicator will change to red for a short while (less than ten seconds) and then back to blue while ALIF unit performs the reset and should then change to an alternative color, usually orange initially, signifying that the operation is complete.
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.

Once the mode has been set to AIM control, an ALIF will remain operating that way until it undergoes a factory reset. If set to Matrix Mode (P2P), an ALIF will remain thus until it undergoes a factory reset or is discovered by an AIM server.

Note:When the modules enter Mini Matrix mode, you can cancel auto-SoL at any point by pressing Ctrl-Alt-C.

PLACING THE DEVICE INTO RECOVERY MODE
Recovery mode may allow an ALIF unit to be diagnosed or upgraded in the event of the main mode being non-operational. To boot the device into recovery mode 1 Power on the ALIF unit. 2 Use a long narrow implement (e.g. a
straightened-out paper clip) to press-and-hold the recessed reset button on the front panel (for less than ten seconds) until the status indicator starts alternating red/green. Note: A solid blue indication will occur after the ten second period. 3 Release the reset switch.The indicator will change to red for a short while (less than ten seconds) and then alternating red/green signifying that the device is in recovery mode. Note: If the indicator turns blue, then a factory reset has been performed instead, the device will not be in recovery mode and the operation will need to be attempted again.

CONFIGURING DUAL TOUCHSCREENS
When a single touchscreen is used with an ALIF RX, it should operate correctly as soon as the USB link is made between the screen and the ALIF RX. However, if two touchscreens are installed it may be necessary to instruct the ALIF RX which screen to correctly attribute to each USB input.

To attribute dual touchscreens 1 Access the Configuration pages on the ALIF RX – see page 29.

CREATING AN UNMANAGED MATRIX
Although ALIF units are most often organised and managed by a central AIM server, it is possible to create small networks of ALIF units, most often in matrix arrangements, ie multiple TX and RX units which can freely cross- connect.

INSTALLATION

CONFIGURATION

OPERATION

FURTHER INFORMATION

This method of connection works well for small numbers of TX and RX units, but will become more difficult to manage as more units are attached.The maximum number of TX sources that can be made available to any RX is sixteen.
To create an unmanaged matrix 1 Connect ALIF TX and RX units (with their various hosts and peripherals) to a suitable
switch, as described in the Installation section – see page 12.
Note:ALIF4000 modules can also be mixed within the same matrix.
Note: If any device was previously managed by AIM, then it will need to be given a factory reset before continuing with this procedure.There must not be an AIM connected on the matrix network otherwise, when such devices undergo a factory reset, they will automatically revert to AIM control.
You now need to perform the following procedure on each ALIF RX in turn:
2 Access the Configuration pages – see page 29.
3 Click the Transmitters option from the list on the left side.This page will list all of the available TX units which are not under AIM control. See page 41.
4 Click the Presets option from the list on the left side. Use this page to add each TX unit to the list of presets for the RX that you are editing. See page 36.

To use the matrix · On each RX, use the OSD to access the required TX units in the usual manner.

EDID details listed include: Manufacturer, model, serial number, manufacture date, EDID version as well as supported (and preferred) EDID modes, maximum bits per color, encodings, colorimetry and dynamic range masterings supported by the monitor. Note: EDID modes that are supported by the monitor but not by the device will be greyed out. In cases where a resolution reported by the video display is supported, but at a lower frame rate than the display calls for, such entries will be shown in italics.
Compatibility Check – WARNING: Disabling this option can result in damage to display monitors in certain circumstances. When ticked this option confirms video compatibility between the source and display device, (such as the video display’s maximum resolution, bpp, etc.) and prevents signals being sent that the video display can’t support.When unticked, signals will always be sent regardless of video display’s declared capabilities. If you untick the option, the following warning will be displayed:

Freeze Frame On Loss – If disabled (default), video will blank when a video connection error occurs. If enabled, video will freeze (or remain blank if no video yet received) when error occurs. Video will resume once error clears. Video will blank if frozen and connection is terminated (eg. different preset selected). A coloured border and messages can be added in the Connection Notification Settings – see page 34. Frame Rate Switching – Determines the strategy to use for the frame rate when switching resolutions. Similar in function to the Match Frame Rate setting on AIM servers: Force 60 – The frame rate is always forced to be 60Hz unless the Compatibility check option is on and the monitor does not indicate it supports 60Hz. Retain – When switching to the same resolution with a potentially different frame rate, it will retain the current frame. Auto – The frame rate always changes to match the mode it is connected to.
Audio Ports This page provides basic information about the analog and digital audio ports located on the RX unit. Enabled – Confirms whether the audio ports are enabled or disabled. Connected – Confirms whether devices are connected to respective ports. Gain – (Analog audio only) Determines the microphone amplification level: None – no device connected on this port. Mic – standard gain for normal microphone input devices. Mic boost – 20dB boost to volume for microphone input devices.

Audio EDID Details – Click the Details button to show a popup listing the audio capabilities of the device connected to that video port. Unsupported formats will be greyed out. Compatibility Check – When ticked, the RX will not output audio on this port if it is not compatible with the attached device’s audio capabilities. If unticked, audio will be output regardless of the attached device’s capabilities. For example, if an attached device supports 2 channel stereo but the incoming stream is 6 channels, turning this off may allow L & R audio output to work – if the attached device can cope, but other channels will be lost (ie. there is no down-mix support).
USB Ports This page provides basic information about the USB ports numbered 1 to 4 inclusive, located on the RX unit. Type – Identifies the type of the USB port. Port 1 on the front of the RX is Transparent, 2-3 on the front, 4-5 on the back are the Emulated ports. Enabled – Confirms whether the USB ports are enabled or disabled. HID Only – (For emulated USB ports only) When ticked, all ports are limited to supporting Human Interface Devices only, such as keyboards and mice. Disable Mass Storage – When ticked, this option prevents the use of USB mass storage devices on the receiver unit.This could be useful in situations where smart card readers need to be used for security purposes but the use of USB drives need to be prevented. Security – (For emulated USB ports only) Controls whether USB data is encrypted. On forces always on, Off forces always off and Prefer off will be off unless the TX requests it.

Socket – Details each operational network socket and what connection speeds they have established. Socket 2 is determined by the SFP module plugged into it.
MAC Address – Displays the unique, fixed hardware identification number for each port.
Link Up – Indicates whether the link state of this network interface is up.This should be the case if the device is connected to a functioning network.
IP Address – This shows the IP address in use, which can be obtained via DHCP, a static IP or a link local (zero-config).
Netmask – The netmask of this network interface.The device can function in a network zero-config state which does not require the setting of a static netmask.
Gateway – The gateway address of this network interface.The device can function in a network zero-config state which does not require the setting of a static gateway.
Static IP Address – When the DHCP enabled’ option (below) is unchecked, click onEdit’ to enter/edit a static IP Address, Netmask and Gateway for the unit.
DHCP Enabled – When ticked, the corresponding port will derive its IP Address, Netmask and Gateway details from the DHCP server listed in the field below.

DHCP Server Address – Indicates the server that provided the DHCP details. Routing Table – Click on `Details’ to show the routing table entries corresponding to this network interface. In it are the destination address, gateway and netmask for the routes to particular network destinations.
Network Information Default Domain – Reserved for future use. Independent Networks – When ticked, the ALIF1100 / ALIF2100 receiver will treat its two main network ports as independent routes to the transmitter(s) and not attempt to find secondary cross connections, which may not be possible due to the network topology.This setting will have no effect when ALIF1100 / ALIF2100 receivers link with ALIF1100 / ALIF2100 or ALIF4000 transmitters due to their use of auto discovery. However, when an ALIF1100 / ALIF2100 receiver links with other dual port ALIF transmitters (such as an ALIF2002T), enabling this option can prevent unnecessary delays due to the time taken looking for routes that are effectively network dead ends. Route of Last Resort – In a multi- interface device such as this, the interface which is ticked will be used as the default whenever it is unclear which interface should be used for network traffic.

Video Ports This page provides basic information about the two video ports located on the TX unit.
Enabled – Confirms whether each video port is enabled or disabled. Connected – Confirms whether functioning host video drivers are connected to the two video ports.
EDID Source – Lists the EDID mode currently being output on the two video connectors.An option called Saved attached monitor is available and will save that first RX’s EDID in persistent storage and use that EDID forever (including over reboot, powercycle, etc) until it is cleared (see below) or a Fixed EDID is selected instead.
To save a monitor EDID and use it for that given video and/or audio port, select the Saved Attached Monitor option. The current Attached monitor EDID will be saved in persistent storage on the TX and used from now on by the TX until is it cleared (see below).
To clear the saved monitor EDID, either: · Factory reset the TX · Select “Attached Monitor” EDID on both the video and audio EDID
Source settings for the same physical DP port. For more information about how video and audio EDID data are derived, see Support for analog and digital audio. Note: Fixed EDIDs were updated in v3.00 to add support for higher frame rates at each fixed EDID resolution.The default frame rate remains as given in the fixed EDID name (eg. 60), however, HD and higher resolutions will include higher rates which are supported at those resolutions. eg. 240Hz for 1920x1080p60.

Dynamic Range – This option is shown only when a fixed EDID is selected.These settings are fixed at SDR8 (8bpc) for this model.
Attached Monitor Receiver – If the Attached monitor’ option has been selected as theEDID Source’, then this displays the name of the RX device that supplied the EDID currently being used.
EDID Optimization – When ticked, and if the EDID source option is set to `Attached monitor’; upon connecting with a new receiver, the transmitter will compare the preferred video mode of the new monitor with the current video output from the host PC. Only if they differ will the transmitter present the new monitor’s EDID to the host PC.This option speeds up switching as the host PCs graphics card does not have to go through a hotplug detect routine each time a new receiver is connected. If this setting is unticked, the transmitter will always present a new EDID to the host PC.
Background Refresh (frames) – The system will send all changing video as soon as it changes. In addition, it is possible to send unchanging video in the background, to overcome problems of lost network traffic. This control will configure how often a whole frame of video will be sent alongside changing video. In situations of frequently changing video, or high reliability networks, this value can be set to a higher number, or even set to disabled.
Compression Type – Allows you to select the compression method to best suit the nature of the video sources. Settings are: Pixel Perfect, Adaptive, Smoothest Video or Advanced (which allows you to set the maximum and minimum compression levels).

Frame Skipping – Frame Skipping involves `missing out’ video frames between those captured by the TX unit. For video sources that update only infrequently or for those that update very frequently but where high fidelity is not required, frame skipping is a good strategy for reducing the overall bandwidth consumed by the system. Range: 0 to 100%.
Magic Eye – When ticked, this feature increases performance and reduces network traffic if ALIF units are used with host computers that have dithered video output. It also improves performance if the video source is noisy.
Max Bits per Pixel – These settings are fixed at 24bpp (ie, 8bpc) for this model.
Multicast Addresses – This section lists all video multicast IP addresses that have been configured. Setting the field to a blank (empty string) value will cause the system to automatically generate a default multicast address.

Audio Ports This page provides basic information about the audio ports located on
the TX unit.
Enabled – Confirms whether the audio ports are enabled or disabled.
Connected – Confirms whether devices are connected to respective ports.
EDID Source – Determines which audio EDID should be used:
Attached Monitor – use the audio capabilities reported by the monitor.
Saved Attached Monitor – save the audio capabilities reported by the attached monitor EDID in persistent storage on the TX and use them until they are cleared (see below).
None – remove audio support from the EDID presented by the TX to the
connected PC.
2-Channel – apply a generic stereo audio EDID.
To clear the saved monitor EDID, either:
· Factory reset the TX
· Select “Attached Monitor” EDID on both the video and audio EDID Source settings for the same physical DP port.
Attached Monitor Receiver – If the EDID source option is set to Attached monitor’, then this displays the name of the RX device that supplied the EDID currently being used. EDID Optimization – When ticked, and if the EDID source option is set to Attached monitor’; upon connecting with a new receiver, the transmitter will compare the preferred audio mode of the new monitor with the current audio output from the host PC. Only if they differ will the transmitter present the new monitor’s EDID to the host PC.This option speeds up switching as the host PCs graphics card does not have to go through a hotplug detect routine each time a new receiver is connected. If this setting is unticked, the transmitter will always present a new EDID to the host PC.
Multicast Addresses – This section lists all audio multicast IP addresses that have been configured. Setting the field to a blank (empty string) value will cause the system to automatically generate a default multicast address.

USB Ports This page provides basic information about the USB ports located on the
TX unit.
Type – Identifies the type of the USB port.
Enabled – Confirms whether the USB ports are enabled or disabled.
Connected – Confirms whether valid devices are connected to either USB port. Note:As both USB ports share the same physical port, it is not possible to detect whether a specific port has a device connected.
Rate Limit – This option allows you to place an upper limit on the bandwidth that can be consumed by the transparent USB subsystem as a whole.This can be useful in situations where the overall network bandwidth is quite low and high resolution video performance is being impacted by USB operation; particularly during large file transfers to or from a mass storage device inserted into the ALIF receiver. Using this option you can choose an appropriate USB bandwidth rate limit between 1 and 480Mbps.
Reserved Ports – Allows USB ports to be optionally reserved for use with particular devices. Once reserved, certain rules can be applied to them via the AdderLink Infinity Manager (AIM) application.
Present Boot Keyboard – When ticked, the TX 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.
Max Hub Size – Using this option you can select whether the TX 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.
Security – Controls whether USB data is encrypted. On forces always on, Off forces always off and Prefer off will be off unless the RX requests
it.

Serial Port This page provides basic information about the serial option port located available on the AUX USB port located on the front panel of the TX unit.
Enabled – Confirms whether the serial port is enabled or disabled. Speed – The `baud rate’ of the serial device.
Data Bits – The number of data bits to be used (5, 6, 7, or 8). Stop Bits – The number of stop bits to be used (1 or 2). Parity – The parity checking to be used (none, odd or even).

APPENDIX B – Support for analog and digital audio
The ALIF1100 and 2100 ranges benefit from multiple audio signal streams: · Uni-directional analog audio – from the host PCs jack socket, · Uni- directional digital audio – via the video connection, · Bi-directional digital audio – via the USB connection (converted to/from analog). Even though the analog and digital outputs from a particular host PC might be carrying signals that originated from the same audio source, they are handled separately throughout the ALIF system and can never be mixed. For digital audio derived from the video connection, the host PC needs to know details of the required signal to send out, eg 16 or 24-bit, 48, 88.2 or 96kHz sample rate, etc, so a valid definition of the requirement must be sent to the host PC.This is done as an audio sub-set of the EDID definition that is used to declare the video display capabilities/ requirements. In the diagram below the display and speaker installation send their video and digital audio portions of the EDID (Extended Display Identification Data) definition via the ALIF2100 receiver and transmitter to the host PC:
In response, the host PC begins sending video and audio signals that are appropriate for the receiving peripherals:

This presents an issue for the host PC and its ALIF transmitter as they must now respond to separate EDID definitions from the video display on one receiver (which will probably also have its own EDID audio sub-set) and the EDID definition from the digital audio device on the other receiver:

To solve potential conflicts, the ALIF transmitter uses a set of rules to determine how it mixes different EDID definitions. Firstly, for any connected video or digital audio devices, the ALIF system can consider each one using any of three selectable states:
· Attached – ALIF will interrogate the attached video/audio device to ascertain its exact capabilities/requirements.
· Fixed – ALIF will use a fixed definition (e.g 1920x1080p60 and 2-channel audio) to represent the video/audio device(s).
· None – No representation will be made for the device.
The above states are then combined by the ALIF1100/2100 transmitter, as connections are made to the different devices, using the following rules:

FURTHER INFORMATION

In the above case, the video and digital audio from the host PC are both sent to the same receiver. However, the flexibility of the ALIF system is such that peripherals and hosts can be mixed as required. For instance, the video feed could be sent to one receiver, while the digital audio is used by a set of speakers on a different receiver:

Fixed Fixed/Attached

Merge the video and audio EDID definitions. Send video EDID definition only. Use whichever EDID definition is available first.
Wait for the Attached device to declare and then use its data to modify those of the Fixed device. Note:The video EDID retains precedence for setting general items, such as serial no., manufacturer, etc.

Note:The analog audio is switched entirely separately to the digital audio feed.

APPENDIX C – Tips for success when networking ALIF units
ALIF units use multiple strategies to minimize the amount of data that they send across networks. However, data overheads can be quite high, particularly when very high resolution video is being transferred, so it is important to take steps to maximize network efficiency and help minimize data output.The tips given in this section have been proven to produce very beneficial results.
Summary of steps · Choose the right kind of switch.
· Create an efficient network layout.
· Configure the switches and devices correctly.
Choosing the right switch Layer 2 switches are what bind all of the hosts together in the subnet. However, they are all not created equally, so choose carefully. In particular look for the following:
· 10Gigabit ports,
· Support for IGMP v2 (or v3) snooping,
· Support for Jumbo frames up to 9216-byte size,
· High bandwidth connections between switches, preferably Fiber Channel.
· Look for switches that perform their most onerous tasks (e.g. IGMP snooping) using multiple dedicated processors (ASICS).
· Ensure the maximum number of concurrent `snoopable groups’ the switch can handle meets or exceeds the number of ALIF transmitters that will be used to create multicast groups.
· Check the throughput of the switch: Full duplex, 10Gbps up- and down- stream speeds per port.
· Use the same switch make and model throughout a single subnet.
· You also need a Layer 3 switch. Ensure that it can operate efficiently as an IGMP Querier.

Creating an efficient network layout Network layout is vital.The use of IGMP snooping also introduces certain constraints, so take heed:
· Keep it flat. Use a basic line-cascade structure rather than a pyramid or tree arrangement.
· Keep the distances between the switches as short as possible.
· Ensure sufficient bandwidth between switches to eliminate bottlenecks.
· Where the AIM server is used to administer multiple ALIF transceivers, ensure the AIM server and all ALIF units reside in the same subnet.
· Do not use VGA to DisplayPortTM converters, instead replace VGA video cards in older systems with suitable DisplayPortTM replacements. Converters cause ALIF TX units to massively increase data output.
· Wherever possible, create a private network.
The recommended layout The layout shown below has been found to provide the most efficient network layout for rapid throughput when using IGMP snooping:

· Use no more than two cascade levels. · Ensure high bandwidth between the two L2 switches and very high bandwidth between
the top L2 and the L3.Typically 10GB and 20GB, respectively for 48 port L2 switches.

Configuring the switches and devices The layout is vital but so too is the configuration: · Enable IGMP Snooping on all L2 switches. · Ensure that IGMP Fast-Leave is enabled on all switches with ALIF units connected
directly to them. · Enable the L3 switch as an IGMP Querier. · Enable Spanning Tree Protocol (STP) on all switches and importantly also enable
portfast (only) on all switch ports that have ALIF units connected. · If any hosts will use any video resolutions using 2048 horizontal pixels (e.g. 2048 x
1152, 2048 x 2048), ensure that Jumbo Frames are enabled on all switches. · Choose an appropriate forwarding mode on all switches. Use Cut-through if available,
otherwise Store and forward. · Optimize the settings on the ALIF transmitters:
· If moving video images are being shown frequently, then leave Frame Skipping at a low percentage and instead reduce the Peak bandwidth limiter.
· Where screens are quite static, try increasing the Background Refresh interval and/ or increasing the Frame skipping percentage setting.
Make changes to the ALIF transmitters 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.
· Ensure that all ALIF units are fully updated to the latest firmware version (at least v2.1).

APPENDIX D – Troubleshooting
Problem: The video image of the ALIF receiver shows horizontal lines across the screen.
This issue is known as Blinding because the resulting video image looks as though you’re viewing it through a venetian blind.
When video is transmitted by ALIF units, the various lines of each screen are divided up and transmitted as separate data packets. If the reception of those packets is disturbed, then blinding is caused.The lines are displayed in place of the missing video data packets.
There are several possible causes for the loss of data packets:
· Incorrect switch configuration.The problem could be caused by multicast flooding, which causes unnecessary network traffic.This is what IGMP snooping is designed to combat, however, there can be numerous causes of the flooding.
· Speed/memory bandwidth issues within one or more switches.The speed and capabilities of different switch models varies greatly. If a switch cannot maintain pace with the quantity of data being sent through it, then it will inevitably start dropping packets.
· One or more ALIF units may be outputting Jumbo frames due to the video resolution (2048 horizontal pixels) being used. If Jumbo frames are output by an ALIF unit, but the network switches have not been configured to use jumbo frames, the switches will attempt to break the large packets down into standard packets.This process introduces a certain latency and could be a cause for dropped packets.

Remedies: · Ensure that IGMP snooping is enabled on all switches within the subnet. · Where each ALIF unit is connected as the sole device on a port connection to
a switch, enable IGMP Fast-Leave (aka Immediate Leave) to reduce unnecessary processing on each switch. · Check the video resolution(s) being fed into the ALIF transmitters. If resolutions using 2048 horizontal pixels are unavoidable then ensure that Jumbo frames are enabled on all switches. · Check the forwarding mode on the switches. If Store and forward is being used, try selecting Cut-through as this mode causes reduced latency on lesser switch designs. · Ensure that one device within the subnet is correctly configured as an IGMP Querier, usually a layer 3 switch or multicast router. · Try adjusting the transmitter settings on each ALIF to make the output data stream as efficient as possible. See ALIF transmitter video settings for details.

Problem:The audio output of the ALIF receiver sounds like a scratched record. This issue is called Audio crackle and is a symptom of the same problem that produces blinding (see previous page).The issue is related to missing data packets. Remedies: As per blinding discussed previously.
Problem: AIM cannot locate working ALIF units. There are a few possible causes: · The ALIF units must be reset back to their zero config IP addresses for AIM discovery.
If you have a working network of ALIF’s without AIM and then add AIM to the network, AIM will not discover the ALIFs until they are reset to the zero config IP addresses. · This could be caused by Layer 2 Cisco switches that have Spanning Tree Protocol (STP) enabled but do not also have portfast enabled on the ports to which ALIF units are connected.Without portfast enabled,ALIF units will all be assigned the same zero config IP address at reboot and AIM will only acquire them one at a time on a random basis. You can easily tell whether portfast is enabled on a switch that is running STP: When you plug the link cable from a working ALIF unit into the switch port, check how long it takes for the port indicator to change from orange to green. If it takes roughly one second, portfast is on; if it takes roughly thirty seconds then portfast is disabled. Remedies: · Ensure that the ALIF units and the AIM server are located within the same subnet because AIM cannot cross subnet boundaries. · Manually reset the ALIF units to their zero config IP addresses. · Enable portfast on all switch ports that have ALIF units attached to them or try temporarily disabling STP on the switches while AIM is attempting to locate ALIF units.

APPENDIX E – Glossary
Internet Group Management Protocol Where an ALIF transmitter is required to stream video to two or more receivers, multicasting is the method used.
Multicasting involves the delivery of identical data to multiple receivers simultaneously without the need to maintain individual links.When multicast data packets enter a subnet, the natural reaction of the switches that bind all the hosts together within the subnet, is to spread the multicast data to all of their ports.This is referred to as Multicast flooding and means that the hosts (or at least their network interfaces) are required to process plenty of data that they didn’t request. IGMP offers a partial solution.
The Internet Group Management Protocol (IGMP) is designed to prevent multicast flooding by allowing Layer 3 switches to check whether host computers within their care are interested in receiving particular multicast transmissions.They can then direct multicast data only to those points that require it and can shut off a multicast stream if the subnet has no recipients.
There are currently three IGMP versions: 1, 2 and 3, with each version building upon the capabilities of the previous one:
· IGMPv1 allows host computers to opt into a multicast transmission using a Join Group message; it is then incumbent on the router to discover when they no longer wish to receive; this is achieved by polling them (see IGMP Querier below) until they no longer respond.
· IGMPv2 includes the means for hosts to opt out as well as in, using a Leave Group message.
· IGMPv3 encompasses the abilities of versions 1 and 2 but also adds the ability for hosts to specify particular sources of multicast data.
ADDERLinkTM INFINITY units make use of IGMPv2 when performing multicasts to ensure that no unnecessary congestion is caused.

IGMP Snooping The IGMP messages are effective but only operate at layer 2 – intended for routers to determine whether multicast data should enter a subnet. A relatively recent development has taken place within the switches that glue together all of the hosts within each subnet: IGMP Snooping. IGMP snooping means these layer 2 devices now have the ability to take a peek at the IGMP messages. As a result, the switches can then determine exactly which of their own hosts have requested to receive a multicast ­ and only pass on multicast data to those hosts.
IGMP Querier When IGMP is used, each subnet requires one Layer 3 switch to act as a Querier. In this lead role, the switch periodically sends out IGMP Query messages and in response all hosts report which multicast streams they wish to receive.The Querier device and all snooping Layer 2 switches then update their lists accordingly (the lists are also updated when Join Group and Leave Group (IGMPv2) messages are received).
IGMP Fast-Leave (aka Immediate Leave) When a device/host no longer wishes to receive a multicast transmission, it can issue an IGMP Leave Group message as mentioned above.This causes the switch to issue an IGMP Group-Specific Query message on the port (that the Leave Group was received on) to check no other receivers exist on that connection that wish to remain a part of the multicast.This process has a cost in terms of switch processor activity and time.
Where ALIF units are connected directly to the switch (with no other devices on the same port) then enabling IGMP Fast-Leave mode means that switches can immediately remove receivers without going through a full checking procedure.Where multiple units are regularly joining and leaving multicasts, this can speed up performance considerably.

Jumbo frames (Jumbo packets) Since its commercial introduction in 1980, the Ethernet standard has been successfully extended and adapted to keep pace with the ever improving capabilities of computer systems.The achievable data rates, for instance, have risen in ten-fold leaps from the original 10Mbit/s to a current maximum of 100Gbit/s.
While data speeds have increased massively, the standard defining the number of bytes (known as the Payload) placed into each data packet has remained resolutely stuck at its original level of 1500 bytes.This standard was set during the original speed era (10Mbits/s) and offered the best compromise at that speed between the time taken to process each packet and the time required to resend faulty packets due to transmission errors.
But now networks are much faster and files/data streams are much larger; so time for a change? Unfortunately, a wholesale change to the packet size is not straightforward as it is a fundamental standard and changing it would mean a loss of backward compatibility with older systems.
Larger payload options have been around for a while, however, they have often been vendor specific and at present they remain outside the official standard.There is, however, increased consensus on an optional `Jumbo’ payload size of 9000 bytes and this is fully supported by the ADDERLinkTM INFINITY (ALIF) units.
Jumbo frames (or Jumbo packets) offer advantages for ALIF units when transmitting certain high resolution video signals across a network.This is because the increased data in each packet reduces the number of packets that need to be transferred and dealt with – thus reducing latency times.
The main problem is that for jumbo frames to be possible on a network, all of the devices on the network must support them.

Spanning Tree Protocol (STP) In order to build a robust network, it is necessary to include certain levels of redundancy within the interconnections between switches.This will help to ensure that a failure of one link does not lead to a
complete failure of the whole network.
The danger of multiple links is that data packets, especially multicast packets, become involved in continual loops as neighbouring switches use the duplicated links to send and resend them to each other.
To prevent such bridging loops from occurring, the Spanning Tree Protocol (STP), operating at layer 2, is used within each switch. STP encourages all switches to communicate and learn about each other. It prevents bridging loops by blocking newly discovered links until it can discover the nature of the link: is it a new host or a new switch?
The problem with this is that the discovery process can take up to 50 seconds before the block is lifted, causing problematic timeouts.
The answer to this issue is to enable the portfast variable for all host links on a switch.This will cause any new connection to go immediately into forwarding mode. However, take particular care not to enable portfast on any switch to switch connections as this will result in bridging loops.

Forwarding modes In essence, the job of a layer 2 switch is to transfer as fast as possible, data packets arriving at one port out to another port as determined by the destination address. This is known as data forwarding and most switches offer a choice of methods to achieve this. Choosing the most appropriate forwarding method can often have a sizeable impact on the overall speed of switching:
· Store and forward is the original method and requires the switch to save each entire data packet to buffer memory, run an error check and then forward if no error is found (or otherwise discard it).
· Cut-through was developed to address the latency issues suffered by some store and forward switches. The switch begins interpreting each data packet as it arrives. Once the initial addressing information has been read, the switch immediately begins forwarding the data packet while the remainder is still arriving. Once all of the packet has been received, an error check is performed and, if necessary, the packet is tagged as being in error.This checking `on-the-fly’ means that cut-through switches cannot discard faulty packets themselves. However, on receipt of the marked packet, a host will carry out the discard process.
· Fragment-free is a hybrid of the above two methods. It waits until the first 64 bits have been received before beginning to forward each data packet.This way the switch is more likely to locate and discard faulty packets that are fragmented due to collisions with other data packets.
· Adaptive switches automatically choose between the above methods. Usually they start out as a cut-through switches and change to store and forward or fragmentfree methods if large number of errors or collisions are
detected.
So which one to choose? The Cut-through method has the least latency so is usually the best to use with ADDERLinkTM INFINITY units. However, if the network components and/or cabling generate a lot of errors, the Store and forward method should probably be used. On higher end store and forward switches, latency is rarely an issue.

Layer 2 and Layer 3:The OSI model When discussing network switches, the terms Layer 2 and Layer 3 are very often used.These refer to parts of the Open System Interconnection (OSI) model, a standardized way to categorize the necessary functions of any standard network. There are seven layers in the OSI model and these define the steps needed to get the data created by you (imagine that you are Layer 8) reliably down onto the transmission medium (the cable, optical fiber, radio wave, etc.) that carries the data to another user; to complete the picture, consider the transmission medium is Layer 0. In general, think of the functions carried out by the layers at the top as being complex, becoming less complex as you go lower down.
As your data travel down from you towards the transmission medium (the cable), they are successively encapsulated at each layer within a new wrapper (along with a few instructions), ready for transport. Once transmission has been made to the intended destination, the reverse occurs: Each wrapper is stripped away and the instructions examined until finally only the original data are left. So why are Layer 2 and Layer 3 of particular importance when discussing ADDERLinkTM INFINITY? Because the successful transmission of data relies upon fast and reliable passage through network switches ­ and most of these operate at either Layer 2 or Layer 3. The job of any network switch is to receive each incoming network packet, strip away only the first few wrappers to discover the intended destination then rewrap the packet and send it in the correct direction.

In simplified terms, the wrapper that is added at Layer 2 (by the sending system) includes the physical address of the intended recipient system, i.e. the unique MAC address (for example, 09:f8:33:d7:66:12) that is assigned to every networking device at manufacture. Deciphering recipients at this level is more straightforward than at Layer 3, where the address of the recipient is represented by a logical IP address (e.g. 192.168.0.10) and requires greater knowledge of the surrounding network structure. Due to their more complex circuitry, Layer 3 switches are more expensive than Layer 2 switches of a similar build quality and are used more sparingly within installations.
