Specifications

InRow RP CW Installation38
Building Management System (BMS). The Modbus interface allows each InRow RP to
communicate with the BMS. Use a three-wire cable to connect each InRow RP in turn. Wire a terminator
resistor (150 Ohm, 1/4 W) into the Modbus master and the final InRow RP between Modbus D0 and
Modbus D1. This terminator is included in the installation kit (see “Install kit inventory” on page 5).
Each InRow RP has a three-wire Modbus terminal on the user interface. A connector with screw
terminals is used to allow wiring to be attached. See “User interface connectors” on page 32 for specific
layout of the user interface.
For information on setup of Modbus parameters, see the InRow RP Operation manual.
