Communication Installation

IQ 250/260 Communication

The IQ 250/260 Meter provides RS485 communication speaking Modbus ASCII, Modbus RTU, and DNP 3.0

protocols.

RS485 / KYZ Output (Com 2)

Com 2 provides a combination RS485 and an Energy Pulse Output (KYZ pulse). See Chapter 2 for the KYZ Out-

put Speciﬁcations; see Chapter 6 for Pulse Constants.

RS485

allows you to connect one or multiple IQ 250/260 meters to a PC or other device, at either a local or remote

site. All RS485 connections are viable for up to 4000 feet (1219.20 meters).
