Ethernet gateway

Ethernet gateway is a communications method that allows you to communicate through a
gateway device to a serial network.
When a meter with gateway capabilities is installed on an Ethernet network, a client device (such
as an energy management system) can communicate through the gateway meter to a serial
network of devices connected to the gateway meter's serial port(s). The maximum number of
devices on the serial network is determined by the limitations of the gateway meter's serial port.
A LAN/WAN
B Ethernet gateway meter
C Serial RS-485 network of devices
D Terminating resistor
There are two types of Ethernet gateways that you can configure on your meter:
• EtherGate – A single TCP connection communicates through the gateway meter to a serial
network of devices.
• Modbus gateway – Up to a maximum of 32 Modbus client TCP connections communicate
through the gateway meter to a serial network of Modbus devices.
