Certificate management for firmware images

The system firmware files are signed to ensure that only Digi-approved firmware load onto the device.

The TX54 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 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 TX54 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.
