6.6 Upgrading Device Firmware
Your meter has upgradeable firmware. If you need to upgrade your device, download a new firmware file
to the meter through PAS.
Firmware can be downloaded via the Modbus RTU or Modbus/TCP protocol through any communication
port.
To download a new firmware file to your device:
1. Ensure that the communication port you are connected through to the meter operates in Modbus
mode.
2. If you are connected to the meter through a serial interface, it is recommended to set the port
baud rate to 115,200 bps. See Setting Up Serial Communication Ports on how to remotely change
the protocol and baud rate in your meter.
3. Ensure that the On-line button on the PAS toolbar is checked, and then select Flash
Downloader from the Monitor menu and confirm downloading.
4. Point to the firmware upgrade file for your meter, click Open, and then confirm upgrading the
meter.
5. You are asked for the password regardless of the password protection setting in your meter. Type
the meter password, and click OK. If you did not change the password in the meter, enter the
default password 0.
