Chapter 4 Power Software Configuration tool Upgrading Device Firmware
56 Multi-Mon Multiple Circuit Energy Monitor
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 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 “Changing
Port Settings” on how to remotely change the protocol and baud rate in
your meter.
3. Check the On-line button on the Power Software toolbar, select Flash
Downloader from the Monitor menu, and then confirm changes.
4. Point to the firmware upgrade file for your Multi-Mon, click Open, and
then confirm upgrading the device. You would be asked for the
password regardless of the password protection setting in your Multi-
Mon.
5. Type the device password, and click OK.
6. Wait until Power Software completes upgrading your device. It would
take about 3-4 minutes at 115,200 bps to download the file to the
device.
