First step: Confirm the serial network of devices are wired and configured to have the same baud rate, serial port settings (for example, 8N1), and protocol (Modbus). • Confirm each serial device has a unique unit identifier. • Confirm the serial network of devices are connected to the gateway meter’s serial communication port. • Confirm your gateway meter is communicating over Ethernet.
Open the Setup Assistant for your meter. -Navigate to Communications > Serial settings and select the tab for the communications port that the serial network is connected to. -Select Protocol and click Edit. The protocol selection screen appears. -Set the protocol to Modbus Master. -Navigate to Communications > Network settings and select the TCP/IP tab. -Select Modbus Gateway and click Edit. The Modbus gateway selection screen is displayed. - Select the communications port that the serial network is connected to (and you just set to use the Modbus master protocol) and click OK. The Modbus gateway connection is created. - Create an Ethernet gateway site to access the serial network of devices through your gateway meter.
