There are some requirements to consider before you upgrade your meter’s firmware.

In order to upgrade the meter, you need to:

    NOTE: It is recommended that you change the IP Address Acquisition Mode to Stored during the firmware upgrade. If the mode is set to DCHP, the IP address might change during the upgrade, which will result in a loss of communications with the meter.

  • Make sure the meter’s FTP server is enabled.

  • Have Product Master credentials to login to the meter’s FTP server. The FTP server uses the same user accounts as the meter’s webpages.

  • Download the latest upgrade files from . The upgrade files include:

    • App2.out: this file contains the files needed to upgrade the code and initialization files that run the Ethernet communications.

    • PM5xxx_vX.Y.Z.fwa (where xxx is your meter model and X.Y.Z is the specific firmware version): this file contains all the files needed to upgrade other meter components, such as the meter’s operating system, language files and webpages.

    • PM5500StartUpgrade.shtml

    Save these files to a location you can access from the computer you use to perform the upgrade.
