Update the system firmware

The Connect EZ operating system firmware images consist of a single file with the following naming convention:

platform-version.bin

For example, Connect EZ-25.2.54.xxx

Upgrading from EZ01-M000 revision Z or earlier

All Digi Connect EZ devices built as EZ01-M000 rev Z or earlier must have the bootloader updated in order to update to firmware 24.12.153.123 (or beyond). Rev Z units were built with firmware 24.9.79.162.

To update the bootloader, load the firmware image 24.12.153.1 (82004807_A.bin) following the standard OS firmware update mechanism. This update changes only the “bootloader version” of the device (to 24.12.153.0). The running OS and all settings on the device remain the same.

To get the the firmware image 24.12.153.1 (82004807_A.bin), navigate to the Connect EZ Mini firmware support page.

Manage firmware updates using Digi Remote Manager

If you have a network of many devices, you can use Digi Remote Manager Profiles to manage firmware updates. Profiles ensure all your devices are running the correct firmware version and that all newly installed devices are updated to that same version. For more information, see the Profiles section of the Digi Remote Manager User Guide.

Python and DAL OS firmware updates

Make sure to check the Python version you are using and that it is compatible with the DAL OS firmware version to which you want to upgrade. You may need to update any Python scripts you have so they are compatible with the Python running on the DAL OS firmware version you choose. See Python versions and corresponding DAL OS firmware versions.

Certificate management for firmware images

The system firmware files are signed to ensure that only Digi-approved firmware load onto the device. The Connect EZ device validates the system firmware image as part of the update process and only successfully updates if the system firmware image can be authenticated.

Downgrading

Downgrading to an earlier release of the firmware may result in the device configuration being erased.

Downgrading from firmware version 22.2.9.x

Beginning with firmware version 22.2.9.x, the Connect EZ device uses certificate-based communication for enhanced security when connecting to Digi Remote Manager. If you downgrade your firmware from version 22.2.9.x to version 21.11.x or previous, your device will no longer be able to communicate with Remote Manager.

To remedy this issue, select the device in Remote Manager and select Actions > Reset Device Certificate.
