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).

  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).

    Basic serial communications settings available using the webpages

    Parameter Values Description
    Protocol ION, Modbus RTU, Modbus Master, DNP v3.00, DLMS, EtherGate, GPS: Truetime/Datum, GPS: Arbiter, GPS: Arbiter-Vorne, Factory, None Sets the communications protocol for your meter’s RS-485 port
    NOTE: the none setting stops communications using this port.
    Baud Rate 2400, 4800, 9600, 19200, 38400, 57600, 115200 Sets the data rate, in bits per second
    Unit ID 1 to 9999

    Sets the meter’s unique ID on the RS-485 network

    NOTE: Modbus serial device range 0 to 247

    Advanced serial communications settings available using the webpages

    Parameter Values Description
    RTS Delay 0–1 The delay in seconds before the transmission of the packet.
    Rx Timeout 0.1–15 Sets the transmit delay (timeout for receiving an entire message from a device) in seconds1
    Serial Port 8N1, 8N2, 8E1, 8E2, 8O1, 8O2 Sets the parity and stop bits for the port
    RS485 Bias OFF, ON Turns on biasing when mastering devices over the RS-485 port
    1 Only applies to a subset of protocols
