The meter can function as an Ethernet gateway (EtherGate).

EtherGate is a protocol-agnostic communications method that lets you communicate through a gateway meter to a serial network of devices letting ION or other RTU over TCP data pass through the gateway meter to other networks, including third party systems. When a meter installed on the Ethernet network has EtherGate enabled, a master device (such as an energy management system) can communicate through the gateway meter to a serial network of devices wired to the gateway meter’s COM port. You must create an additional communications connection to the gateway meter in order to read its information.

NOTE: EtherGate supports only one master device.

Before proceeding, make sure you have completed the following tasks:

  • Confirm the serial network of devices are wired to the gateway meter’s serial communication port.

  • Confirm all serial devices are configured to have the same baud rate, serial port settings (for example, 8N1), and protocol (ION).

  • Confirm each serial device has a unique unit identifier (unit ID/address).

  • Confirm your gateway meter is communicating over Ethernet.

You can then configure the gateway meter’s serial port to use the EtherGate protocol, create the EtherGate site in ION Setup or an energy management system, and add the serial devices to the EtherGate site.
