Ethernet communications

The meter supports Modbus TCP, HTTP and FTP protocols and can communicate at data speeds up to 100 Mbps through its Ethernet communications port.

The meter supports a single IP address between two 10/100Base-T Ethernet ports. The second Ethernet port functions as an Ethernet switch, which allows you to have shorter Ethernet cable runs between the meters without requiring additional Ethernet routers or repeaters. This helps simplify network connections and reduce installation time and costs.

Use a Cat 5 cable to connect the meter’s Ethernet port. Your 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.

NOTE: For meters that do not have a display, you must configure each one separately in order to set a unique IP address for each device.

Digital outputs

The meter is equipped with two Form A 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 kWh pulses coming from the meter’s digital output port

The digital outputs can handle voltages less than 30 V AC or 60 V DC (125 mA maximum). For higher voltage applications, use an external relay in the switching circuit.
