Upgrading Meter Firmware
You can upgrade device firmware through any communication
port installed in your meter: a serial port, USB, wireless
GSM/GPRS modem, or via the Internet.
Downloading firmware is only supported through the Modbus
RTU/ASCII and Modbus/TCP protocols. If you are connected
to the meter via a serial port, ensure that it operates in
Modbus mode. It is also recommended to set the serial port
baud rate to 115,200 bps. See
Configuring Communications
on how to remotely change the protocol and baud rate in
your meter.
To download a firmware file to your meter:
1. Check the On-line button on the PAS toolbar, select
Flash Downloader from the Monitor menu, and then
confirm changes.
2. Point to the firmware upgrade file, click Open, and
then confirm upgrading the meter.
3. When asked for the password, type the meter
password, and click OK.
4. Wait until PAS completes downloading the file. It takes
about 9-10 minutes at 115,200 bps via a serial port, or
about 20 seconds via a USB port, to download the file
to the meter.
