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 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:
1. Ensure that the communication port you are connected
through to the meter operates in Modbus RTU mode.
2. If the port is configured for a different protocol, put it into
Modbus RTU mode either from the front display, or
remotely through PAS. 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.
3. Check the On-line button on the PAS toolbar, select Flash
Downloader from the Monitor menu, and then confirm
changes.
