To perform a firmware update you have to log in to the web interface of the SmartXcan. The SYSTEM menu item takes you to the SYSTEM FUNCTIONS tab. All software specific data can be found there. In the CREATE BACKUP area, a backup copy must be created before an update is performed to prevent possible data loss.
Under FIRMWAREUPDATE the current version of the software is displayed. A message in this field automatically indicates when a new version is available (note network configuration).

By selecting the downloaded and unzipped data, the update can be performed under "Start Update". This process can take up to 5 minutes. During this time the power supply must not be interrupted.
