This article describes the process to update the firmware of nMETOS devices.


List of tools:


Micro USB cable:
Battery:


To manually upload the firmware, there are two different ways the station can be updated.

  1. CONNECTING THE BATTERY (Station opened) or
  2. VIA STATION MENU

In both cases it is better to leave the software Firmware uploader ready.


Setting up the Firmware Uploader

  1. Unplug the battery and solar panel;
  2. Open the program Firmware uploader;
  3. Click on "Select FW" to load the firmware you have downloaded;
  4. Select the Device nMETOS100+;



A) CONNECTING THE BATTERY (Station opened)

NOTE: If you have your station opened already, then continue going through this topic. Otherwise, scroll down to the step B) VIA THE STATION MENU.


Once you have your Firmware Uploader setup, do:

  1. First plug-in the USB cable and the battery; 
  2. Click on Open Port (you will have only 5 seconds before the station quits the uploading process. If you miss the 5 seconds, restart the procedure);


TIP.: make sure there is no other USB cable connected to your computer, it will make the things faster and easier for you since the Windows will only recognize your COM (USB) and automatically setup it on Firmware Uploader
