7 Updating the firmware
TELL always releases its products with the latest firmware version. However, as our products are
being continuously improved, new firmware updates may occasionally be released for the
products, which may include new features along with bug fixes. Therefore, it is recommended that
you always upgrade your product to the latest firmware version available. All released firmware
versions are available on the TELL website, including older versions.
ATTENTION! Downgrading to an earlier version is not supported! Always upgrade your
product to the latest version, otherwise your settings could get wiped due to differences in
functionality between versions.
You can update the firmware of your Adapter2 device locally via USB, or remotely via the Internet.
You can find the firmware file or the desktop update application needed for the update on the
manufacturer's website (https://tell.hu/en) in the product downloads section.
7.1 Updating via USB
You can update the firmware via USB using the desktop update tool (application) or the
programming software.
• Updating via USB using the desktop update application:
- Download the latest update tool (application with .exe extension) from the manufacturer's
website. The update tool includes the firmware as well, therefore the file name is the same
as the firmware version number.
- Open the update tool and click on the “FIRMWARE” button.
- Connect the device to the computer via USB.
- Power up the device and then click on the "Start" button.
Do not power down the device later on!
- Wait until the progress bar shows that the process has completed.
- Use the “Cancel” button to close the pop-up window that shows up while loading the
firmware, with a question that asks if you want to format the drive.
- You can close the update tool when the progress bar shows that the process has completed.
- Wait until the LED status indicator on the device shows activity. You can then connect to the
programming software and check the functioning.
• Updating via USB using the programming software:
- Download the latest firmware file (that has the .tf3 extension) necessary for updating, from
the manufacturer’s website.
- Click on the “Connection type” menu in the programming software.
- Click the „Firmware update” button, and then browse the .tf3 firmware file.
- The update process will start automatically as soon as you click on the “Open” button. Once
the firmware is loaded, the progress window will close automatically and the device will
restart in a few seconds, running on the new firmware.
Using this option, you can also update devices with a lower major firmware version
(e.g., v6), which are not compatible basically with the latest software, but can be made
compatible by updating.
7.2 Updating remotely over the internet
It is also possible to update the firmware of the Adapter2 remotely over the Internet, using the
programming software. After establishing the remote connection, the steps for remote update are
the same as the steps for updating through USB, as specified above.
