How to change the serial number of iMetos

Serial number is a unique identifier assigned by Pessl Instruments. Normally you do not need to change it. The only case is if you need to replace the mother board that has another serial number.

  • You receive an sn.ini file from Pessl Instruments per email
  • Save this file in the same folder where you installed Firmware Updater. Normally c:\program files\metos\Imetos Firmware Upload
  • Start Imetos Firmware Upload program. It will pick up the number from sn.ini and write to the station
  • Delete sn.ini

Troubleshooting guide

  • The climate station is connected but the program gives a message Device not found

    • Check that battery is in good conditions.
    • Check if the led of the station is not blinking. If it is, reset it and try again.
  • The climate station is connected to a comm port but the program reports that that comm port is occupied by another application.

    • Check that no other software (modem, infrared, fax program) is using this comm port.
  • The application had started uploading and after some time interrupted with a message Data transfer error.

    • Try to close other applications running on your PC and start uploading again.
