Ethernet communications
The meter uses Modbus TCP protocol to communicate at data speeds up to 100 Mbps through its Ethernet communications port.
Use a shielded Ethernet cable to connect the meter’s Ethernet port. Ground terminal is not available on meter, shield should be connected to Ground at the other end. Ethernet connection source should be installed in a location that minimizes the overall Ethernet cable routing length.

Ethernet configuration
To communicate with the meter through Ethernet, all devices must have a unique IP address and be set to the same subnet mask and gateway.
•To configure Ethernet communications, see “Setting up Ethernet communications” on page 37.
Digital outputs
The meter is equipped with two digital output ports (D1, D2). You can configure the digital outputs for use in the following applications:
•switching applications, for example, to provide on/off control signals for switching capacitor banks, generators, and other external devices and equipment
•demand synchronization applications, where the meter provides pulse signals to the input of another meter to control its demand period
•energy pulsing applications, where a receiving device determines energy usage by counting the k_h pulses (k_h = kWh, kVARh or kVAh depending on the energy parameter selected) coming from the meter’s digital output port
The digital outputs can handle voltages less than 40 V DC. For higher voltage applications, use an external relay in the switching circuit.
