AIM Manager

My AIM Manager is not seeing any of my Transmitters or Receivers

 Important

There is a known issue with the original AIM when running 3.3 firmware that prevents endpoints being added after January 2018. Upgrade to firmware version 3.5 to resolve this problem.

When setting up an Infinity digital matrix for the first time, if you connect a Transmitter or Receiver to a simple single VLAN network and find that the AIM Manager is not automatically recognising them, then check the following:-

  • The AIM Manager can be set in two modes, either single or multi-subnet mode. This option is only available when you configure its network settings for the first time, and is called Subnet Operation which can either be set as On or Off.
  • With Subnet Operation Off, the AIM Manager will not act as a DHCP Server, which means the endpoints (Transmitters and Receivers) will not be issued with IP addresses and therefore will not find the AIM Manager. Unless you have an external DHCP configured on the network that both offers the endpoints their IP address settings and DHCP Option 125.
  • With Subnet Operation On, the AIM Manager will run a DHCP Server and will provide the network configuration to the endpoints,
  • To determine which mode the AIM is running, navigate to Dashboard -> Settings -> Network. Scroll down the Network settings and look for IP Pool Lower and IP Pool Upper fields. If these are missing then the Subnet Operation mode is set to On and an external DHCP server is required.
  • To change the Subnet Operation mode, you must perform a Full Factory Reset.

 

Other possibilities

  • Check your switch configuration. Make sure that you have portfast enabled, If you are using Cisco switches, make sure that on each port where an Infinity endpoint resides has switchport mode access and spanning-tree portfast set.

 

I can not add any more Transmitters or Receivers to the AIM

Assuming that you are not going over the limit of your AIM's endpoint license and that the AIM is set in single subnet mode, then check the following:-

  • Navigate to Dashboard -> Settings -> Network
  • Scroll down the Network Settings page and look for IP Pool Lower and IP Pool Upper fields.
  • Make sure that the IP range that has been set is sufficient to accommodate the number of endpoints you require.

 


I'm unable to access the AIM Manager

A new or factory reset AIM Manager has a fixed link-local IP address of 169.254.1.3. When you configure the AIM's IP address, it will no longer be available on default link-local address. However, if you forget the IP address that you set, it is still possible to access a Primary AIM on link-local address 169.254.1.2 instead. A backup AIM's IP link-local IP address will be available between 169.254.1.4 and 169.254.1.10, depending on how many you have on the network.


 

What are the functions of an acting Primary AIM?

An acting Primary AIM server is a Backup or Satellite AIM that has taken over control in the absence of a Primary AIM.

It can:

  • Allow endpoints to still make channel changes.
  • Issue DHCP addresses (single-subnet mode only)

It can not:

  • Make changes to the configuration, such as add or edit channels.
  • Accept new or factory reset endpoints

In the event of a Primary AIM failure, the Backup AIM can be promoted to a Primary AIM Manager.


 

When I connect to a shared Channel, why do other users only have View-Only access to the channel?

This can occur for one of the following reasons:-

  1. Someone has already connected to the channel and they are connected in exclusive mode. Exclusive mode allows a user to have full control over a channel, however, other users can only view the channel.
  2. Serial Port is enabled. A common mistake when setting up Channels is to include the serial port when it is not necessary. A serial connection can only operate in a point to point mode due to the limitation of the serial protocol. This means that once someone has established the channel, subsequent connections can only be view-only. Removing Serial from the Channel will resolve this isssue.

 


 

When I try to change Channel, I receive a message saying that the receiver is in use by another user.

 Note

From AIM firmware version 4.8 and above, there is now an option to allow users to force a channel change if Grant All Users Force Disconnect is enabled under Dashboard -> Settings -> General. You will still receive the warning message, however you will be able to click on the force connection link to override the existing channel connection.

Only the person who established the channel connection on a receiver is able to change it. However, this can be overridden by the Administrator either by logging into the receiver, using this AIM web interface or using the API. This message typically appears if the OSD login has timed out and a different user logs into the OSD and proceeds to use it whilst the receiver is already connected to a channel.

To avoid this problem, either make sure that you disconnect the channel before leaving the receiver or set the timeout period on the OSD to a longer duration.

How long are the Log Files stored?

On the first of the month, the AIM automatically archives any Event and Connections logs that are older than a month. Those log are accessible on the Backup page (Dashboard -> Backups).
The log archives are kept for six months.

The log files are not persisted after a firmware upgrade. If you need to keep a copy, make sure that you download them from the AIM first before upgrading.


 

How do the multicast IP addresses get issued to the Transmitters

When a transmitter is added to the AIM, the AIM issues the multicast addresses starting from the custom multicast base address in the network settings. The default multicast based address is 237.1.1.1. The base address can be changed under the Dashboard -> Settings -> Network page and Multicast IP Base.


Can I change the Base Multicast IP address?

The default Multicast IP Base address is 237.1.1.1. You can change this address, however, all the Transmitters will automatically reboot and then reconnect their existing connections.


 

Does the AIM Manager handle the multicast traffic/or act as an IGMP Querier?

No, this is the responsibility of the network switch(s).


 

How do I delete the stored Endpoint firmware from the AIM Manager?

The AIM Manager contains a partition that is used to store firmware for the endpoints, backups of the AIM's database and is also used as part of the upgrade process. If this partition gets full it can prevent the AIM manager from being upgraded as it does not have enough space.

  • To delete the endpoint firmware, navigate to Dashboard -> Updates.
  • At the bottom of the page, you will see a selector. Its main purpose is to allow you to upgrade endpoints without having to upload the firmware again (if it already exists).

    AIM DeleteFirmware
     
  • When you click on either the Receivers or Transmitters radio buttons, it will reveal the endpoint models that the AIM has under its control.
  • You can then choose the firmware type, either Main or Backup. The drop-down list below will then automatically update, showing you which firmware it has stored for the model.
  • The next action is either Install or Delete. Click Delete to remove the firmware.
  • To remove all the firmware, you will need to go through the different permutations of TX, RX, Main, and Backup.
  • This will free up some space.

 

Endpoints (Transmitters and Receivers)

Why do the LED's flash on the front of the Transmitter or Receiver?

Plugin execution pending approval

This plugin was recently added or modified. Until an editor of the site validates the parameters, execution will not be possible.

The flashing indicates that the unit is running in Backup mode which is used to recover the product if there is a problem. This can be for a couple of reasons:-

  • On the back of the unit is a dip switch that is located next to the power socket. If dip switch 1 is ON (down) then this starts the unit in Backup mode. Simply set dip switch to OFF and re-power the endpoint to boot normally.

Infinity DipSwitches

  • The boot strap loader has detected that the main firmware is corrupt. Reloading the firmware should resolve the problem. See Upgrading the Firmware directly for instructions. If you are running firmware older than 3.7 or 4.4 then please read the Longevity Upgrade page.

Video: Why does the Video have a Green or Pink tinge?

There are a couple of reasons why this may be occurring. 1) The video cable is faulty 2) The graphics card is outputting YCBr instead of RGB.


 

Why do I see an "X Downgraded" banner message?

This message can appear if the configuration of either the Transmitter or the Receiver to do not match when doing a point to point connection. For example, if the receiver has the serial setting enabled, but the transmitter does not. For example, if you are connecting an ALIF2000R receiver to an ALIF100T and you see this message, this is because the ALIF100T does not have a serial connection. Disabling the Serial option on the receiver will fix this instance.


Can I use the Tobi Eye Tracker with Infinity

Support for the Tobi Eye Tracker has been added to the ALIF v5.0 firmware. The eye tracker must be used through a powered USB hub as the device requires slightly more current than USB spec dictates as maximum. If this device is switched aggressively it can fail due to the time taken for the driver and device to enumerate and connect. We found it needed a PC with Windows 10 20H2 edition to work.

During the configuration, the user needs to create a profile before they can use the tracker. Connect the tracker directly to the host computer to create the Profile before using with Infinity.
