6.13 Ethernet Communications
Ethernet/IP communications connections are provided through an RJ-45
connector(J8) in the lower right corner of the main power board. This port can be
connected directly to a network port of a PC using a Cat. 5e crossover cable.
Two LEDs are provided directly above the connector. The LINK LED is yellow and
when lit, indicates ethernet connectivity. The ACT led is green and when lit,
indicates communication activity.
The communication protocol for the Ethernet port is selected when ordering the
meter. The available choices are EZ7, Modbus TCP/IP and BACnet IP. See the
ordering information for the available choices in combination with the RS-485
output.
E- Mon Class 3400 Meters can be tied into a local Ethernet network individually.
Multiple RS-485 meters to Ethernet requires optional “EKME” device. Each
device that is connected directly to the ethernet network requires a unique IP
address.
