Configuring serial communications settings using the webpages
You can use the meter’s webpages to configure your serial communications settings.
Before configuring serial parameters, make sure you have a unique unit ID for your meter and
know the serial network settings (protocol, baud rate, parity and stop bits).
To configure the meter’s serial communications settings using the meter webpages:
1. Connect to your meter’s webpages using the meter’s IPv4 address or its IPv6 link local
address, or use self-discovery then double-clicking the meter’s network icon.
2. Navigate to Setup > Serial Port.
3. Enter the appropriate value for the settings.
4. Click Advanced Settings to configure additional settings, if needed (for example, RS485
biasing or Rx Timeout).
