You can upload a file or specify a URI where it can be downloaded from. Be sure to disable the same subnet restriction if you intend to download firmware from a server not in your local network.

By default, the unit beeps and blinks during update. You can disable this using the following form.

You may protect the current firmware from modification. Pressing the hardware reset button will be required to unlock.

Committing the firmware upgrade

After the firmware has been uploaded, you are presented with a form to perform the upgrade.

You can double-check the firmware version. If you wish to cancel the upgrade, it's best to explicitly press 'cancel' in the form so that the uploaded file could be cleaned up.

When you start an upgrade, a message about this briefly appears on the LCD.
