Honeywell 4232CBM Installation And Setup Manual

About the 4232CBM

The 4232CBM Connected Building Module is intended
to provide connection between compatible Honeywell
control panels and supported third-party software and
hardware products. It provides an interface between
the control panel's ECP bus and external equipment
with either RS422 or RS232 interfaces. The connection
and configuration of this device is application-specific.
Please refer to the documentation for your external
equipment for information on which connection method
to use, and how to configure the external device to
communicate properly with the 4232CBM.
NOTE: The connected building features offered by the
4232CBM are not evaluated by ETL or UL.

The 4232CBM module connects to the control panel
via the panel's ECP terminals, and connects to the
external computer or other equipment via either RS422
or RS232 connections, according to the application.
The module is powered via the control panel's ECP
+12VDC connection.
Wiring the Module
Refer to the diagram below for connections.
1. 4232CBM to External Equipment Connection: For RS232 applications, connect the three RS232 lines
(GND, Tx and Rx) to the external equipment. For RS422 applications, connect the four RS422 lines (Tx+/-
and Rx +/-) to the appropriate points on the external equipment.
