The firmware comes in two parts.
Firmware Version / Maintenance Version
e.g.
1.13.1.0 / 1.13.1.0

Starting with firmware version 1.11.1.0, only the left side (application) version is displayed on the main menu.

Firmware Update:
The left side (Firmware Version) is updated via the sysupgrade file.
This firmware contains the user interface, applications, operating system, SSH, etc. The xxxx_firmware_1.13.x.0.sysupgrade file is used to update the firmware through the
Upload Firmware menu option. Choose the “xxxx.sysupgrade” file and choose upload. Then, follow the instructions. More detailed instructions for are found on the firmware download page for your model. https://www.digital-loggers.com/afwup.html

*Updating the sysupgrade file FROM 1.11.4.0 MUST be done via the secure shell, not the web UI. https://www.digital-loggers.com/downloads/product%20manuals/power%20control/Updating_the_power_controller_via_SSH.pdf

* Note for firmware 1.13.3.0 Be sure to update the AVR to 1.13.3.0 to apply the reset fix. (see below)
You may need to use the xxxxx_1.13.3.0_update.avr to accomplish the AVR update if it is not updates via the .maint file.

Maintenance Update: The right-side firmware (.maint) contains the hardware control system, LCD, keypad, GPIO, etc.
The right-side firmware is updated less frequently than the application/system firmware.
If the displayed firmware version is a link, e.g. then the maintenance files should be updated.
- Maintenace file update recommended.
- Maintenace file up to date.

To update the maintenance file, click on the link or from the menu, click on the support link.
You can also look on the support page to see maintenance file update recommendations.
Maintenance update complete instructions: https://www.digital-loggers.com/update_maint.html
The x.x.x.x_update_auto.maint file “should not” cycle the outlets.

In the Maintenance section*, choose the file to upload. Uncheck the “Confirm operations from keypad” if you do not wish to confirm the update on the controller itself.
Press the “Start Maintenance” button.

*If the settings are protected, reset the protection.
Press the reset button near the RJ-45 Ethernet connector and wait about 5 seconds.
You will hear a beep and arrive at the reset menu. You can use the Up/Down arrows to select the kind of reset. The default is "Clear Lock Bits: Clear protection bits only", which is what you want. Press the cycle button.
After the update you don't see that the Maintenance Version has changed or the firmware version link remains, logout and login again, try the update again. Then recheck the version.

** In this release, the AVR should match this 1.13.x version. 

If the AVR is still “out of date” after the update, try the included update.avr file. If you still have issues, contact michael@digital-loggers.com for a “forcereset” file.
