Normal Tesira firmware update procedure

This article describes the typical firmware update process for Tesira devices that can be upgraded directly to the desired firmware version with no intermediate updates required. To determine if an intermediate update is required, please use the Tesira firmware update path calculator.

If an intermediate update is required, follow the steps indicated by the update path calculator to bring your device to the current version.  

Update software

Ensure that your Tesira software and Biamp Canvas software are updated to the latest version.

You can check what version you currently have installed by going to Help→About Tesira​ or Help→About Biamp Canvas.

The latest version can be found at .

While you are at it, don't forget to download the latest Tesira firmware file.

Backup configuration files

If there is a configuration file running on the Tesira hardware, it is always a good idea to save a backup copy. This step is optional, but recommended in case the firmware update is unexpectedly interrupted.

  1. In Tesira software, click the Connect button connect.png or go to System→Network→Connect To System.
  2. Select the desired system in the System List, and click the Connect To System button. This will download the current configuration file from the system, and connect you to it live.
  3. In order to save the file to your computer, you must disconnect from the system.  Press the Disconnect button disconnect.png or go to System→Network→Disconnect From System.
  4. Go to File→Save As to save a copy of the file to your computer.

If there is a Biamp Canvas file loaded to the system, repeat steps 1-4 in Biamp Canvas software.

Apply the firmware update

You are now ready to apply the firmware update, via Tesira software's Device Maintenance dialog.

If you haven't downloaded the firmware update file yet, you can obtain it at

The Tesira update path calculator will inform whether any intermediate firmware versions must be installed during a major version update. 

  1. In Tesira software, click the Device Maintenance button devicemaintenance.png or go to System→Network→Perform Device Maintenance.
  2. Click the Update Firmware button.
  3. Browse to the firmware update file, which will be a .tfa or .tfa2 file.
  4. Select all of the devices that you'd like to update, or click Select All to update all devices. Click OK to begin the upgrade.

Typical firmware updates take 5-15 minutes to complete. Do not remove power or interrupt network connectivity during the update. Updating firmware over a WiFi connection or via a remote internet connection is not recommended. ALL AUDIO WILL STOP DURING A FIRMWARE UPDATE!

  • If there are any TesiraCONNECT TC-5 or TC-5D being updated they will install their updates first.
  • Once TesiraCONNECT has completed its updates Tesira Server-class devices will be updated.
  • Once all of the Server-class devices have fully updated, any Tesira expander devices (EX-IN, EX-OUT, EX-IO, EX-AEC, EX-MOD, EX-LOGIC, Parle mics and amplifiers, EX-UBT) that are configured as part of a system will automatically begin to receive the firmware upgrade from their respective proxy server. This process can take up to 15 minutes, and the expanders will not pass audio or otherwise function during this time. The server device will display a fault of "Expander firmware update in progress" while this process is taking place. When the expanders are finished updating, they will automatically resume passing audio.
    • If there are expanders that are not configured as part of a system, they will not update automatically.
      • If an Expander with older firmware is being added to a configuration with a Server-class device on a newer release it will get its firmware update automatically from the Server-class device when the configuration file is loaded. The Expander does not need to be manually updated prior to configuration.  
      • You can manually update the firmware of an expander by going to Device Maintenance→Remote Devices, select the expander in the list, and clicking on Network Settings. It will prompt you that a firmware update is required on the device.


Occasionally devices will report having failed the firmware update process, this is typically due to software missing a confirmation message that it has completed its update. You can check the device's current firmware version using Device Maintenance→Device Information or by clicking Update Firmware and seeing the version reported in the selection window. If the device reports the expected version then its ready to go, if not, reboot the device and repeat the update process.
