Nexus Meter with Internal Network Option

11.1: Hardware Overview

The Nexus 1250/1252 Meter with the Internal Network Option has all the components of the standard Nexus Meter PLUS the cabability of connecting to a multiple PC’s via Modbus/TCP over Ethernet. Additional hardware is not required to establish a connection from a network to a Nexus with Internal Network Option.

With the Internal Network Option, the Nexus 1250/1252 provides an Ethernet Gateway, allowing access to other Modbus/RTU devices. Additional connections can include a daisy chain of standard Nexus Meters. A daisy chain can include up to 31 meters. If more are desired, the installation of a repeater allows additional meters. (See section 5.15 for repeater details.)
