Upgrading Device Firmware
Your meter has upgradeable firmware. If you need to upgrade your device,
download a new firmware file to the meter through Power Software.
Firmware is downloaded through any communication port. The meter may be
connected to your PC through a serial interface, a dial-up modem or the Internet.
Upgrading firmware is only supported through the Modbus RTU and Modbus/TCP
protocols, so your serial port or modem port should be put into Modbus RTU mode.
To download a new firmware file to your device:
Ensure that the communication port you are connected through to the meter operates in
Modbus RTU mode.
If the port is configured for a different protocol, put it into Modbus RTU mode either from the
front display, or remotely through Power Software. 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
Configuring Communications in your Meter on how to remotely change the protocol and
baud rate in your meter.
Check the On-line button on the Power Software toolbar, select Flash Downloader from the
Monitor menu, and then confirm changes.
