4.11 Upgrading Device Firmware
Your meter has upgradeable firmware. If you need to upgrade your device, you can download a new
firmware file to the meter through PAS.
Firmware can be downloaded through any communication port. The meter can be connected to your PC
through a serial interface, a dial-up modem, the Internet, or the RF modem.
Upgrading is only supported through the Modbus RTU and Modbus/TCP protocols, so your serial port or
a dial-up 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 (factory default).
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 “Changing Port Settings” 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.
4. Point to the firmware upgrade file for your BFM136, click Open, and then confirm upgrading the
device. You would be asked for the password regardless of the password protection setting in
your BFM136.
5. Type the device password, and click OK.
