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:
Ensure that the communication port you are connected through to the
meter operates in Modbus mode.
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.
Ensure that the On-line button on the PAS toolbar is checked, and
then select Flash Downloader from the Monitor menu and confirm
downloading.
Point to the firmware upgrade file for your meter, click Open, and then
confirm upgrading the meter.
