4232CBM
Connected Building Module
INSTALLATION AND SETUP GUIDE

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.
Mounting the Module
Mount the module inside the control panel cabinet
using double-sided tape (supplied). Make sure the
solder connections on the bottom of the PC board do
not touch the cabinet.

NOTES:
A. The connections shown above are used for most applications where the external equipment has a male DE-9
connector (for example, PCs and most home automation equipment).
B. For RS422 applications, refer to the documentation for your external equipment.

2. 4232CBM to Control Panel Connection: Plug the connector of the 4-wire harness (supplied) into the 4-pin
ECP connector on the 4232CBM board. Connect the flying leads to the appropriate control panel ECP
terminals as shown below.

Programming to Enable the Module
The 4232CBM uses up to three ECP device addresses; one address for the RIS (Remote Interactive Service)
device and either one or two emulated keypad addresses, depending on the application.
Refer to the documentation for your external equipment to determine if you also need to enable one or more
keypad addresses. These addresses should be enabled as AUI devices.
To enable RIS functionality in the control panel, follow these programming steps:

Control Programming Notes for Enabling Remote Interactive Service (RIS)
VISTA-15P
VISTA-15PSIA
VISTA-20P
VISTA-20PSIA
VISTA-21iP
VISTA-21iPSIA
• Field ∗ ∗∗ ∗91 Option Selection
Enable RIS by programming data field ∗91 Option Selection, entry 2 as follows:
∗ ∗∗ ∗91 Option Selection (SIA Panels: Options/Call Waiting Disable & RIS Enable)
x 2 (x = see control’s programming instructions for appropriate values)
1 2
Options RIS Enable (SIA Panels: Call Waiting Disable/RIS Enable)

For Entry 2, enter “2” (SIA Panels: enter “2,” or enter “3” if Call Waiting Disable also
desired).

• Field ∗ ∗∗ ∗189 Touch Screen Device Enable
If the application requires emulation of a graphical keypad, then enable a virtual AUI device
address for Remote Services by programming data field ∗189 Touch Screen Device Enable
as follows:
∗ ∗∗ ∗189 AUI Device Enables (for Touchscreen Style Touchpads)
x x x x (x = partition number for installed AUI devices)
AUI 1 AUI 2 AUI 3 AUI 4

Enable Remote Services by entering 5, 6, or 7 (depending on the partition in which
the remote services device is located) in an unused AUI location.
(5 = remote services partition 1; 6 = remote serv. partition 2; 7 = remote serv. partition 3)

Device Addresses: AUI 1 = addr. 1; AUI 2 = addr. 2; AUI 3 = addr. 5; AUI 4 = addr. 6

NOTE: When using the 4232CBM, the selected AUI device address serves as a virtual
device used for Remote Services purposes that allows the control to receive status
information from the external equipment. Therefore, the selected address cannot be used
for an actual AUI Touchscreen.
VISTA-128BPT
VISTA-128BPTSIA
In #93 Device Programming, two device addresses must be programmed to enable remote
interactive services. Set one of these device addresses to type 12 (RIS), which enables RIS
operation. Set the other device address to type 01 (alpha keypad), which enables a virtual
keypad that is also needed for RIS operation.
Note: The default ECP address for RIS functionality is 25. Although some applications may
allow you to change this setting from the external equipment, using the default address is
recommended.

REFER TO THE INSTALLATION AND SETUP GUIDE FOR THE CONTROL WITH WHICH THIS DEVICE IS
USED FOR WARRANTY INFORMATION AND LIMITATIONS OF THE ENTIRE SYSTEM.
