Overview
QThe 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. Adaisy 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.)
