When you run the Doors.NET installer you will see an Application Requirements window. This window will inform you if standard NXT controllers need a firmware upgrade and the version they should be upgraded to.

There will also be a notification in the Live Events grid if the controller needs a firmware upgrade.

During the upgrade the latest firmware versions will be installed into the C:\Keri\DoorsNET\Firmwarefolder.
- Once the install/upgrade has completed, log into the software and go to Setup >> Hardware Setup >> All.

- Highlight the controller listed in the hardware tree.
- Click the Firmware Upgrade icon.

- The Firmware Upgrade tab will appear.
- The controller(s) will appear and their current firmware version will be shown.

- Select the controller or controllers that need to be upgraded (you can select multiple controllers using the Select All tick box)
- Select the new firmware file and click the Apply button.

- A task verification window appears. Click Yes to continue.
- A progress bar will appear on the right side of the selected controller indicating the progress of the firmware upgrade.

- The firmware upgrade is complete once the progress bar has reached 100% and the new firmware version will be displayed.
