Nexus Overview
2.1: The Nexus System
Electro Industries’ Nexus 1250/1252 combines high-end revenue metering with sophisticated power
quality analysis. Its advanced monitoring capabilities provide detailed and precise pictures of any
metered point within a distribution network. The P60N, P40N, P41N and P43N displays are detailed in
Chapter 6. Extensive I/O capability is available in conjunction with all metering functions. The optional
Communicator EXT software allows a user to poll and gather data from multiple Nexus meters installed
at local or remote locations (see the Communicator EXT User Manual for details). On board mass
memory enables the Nexus to retrieve and store multiple logs. The Nexus Meter with Internal Modem
(or Network) Option connects to a PC via standard phone line (or MODBUS/TCP) and a daisy chain of
Nexus Meters via an RS-485 connection. See Chapters 10 and 11 for details.
