The Honeywell 4232CBM is a home automation system interface module for the VISTA Series alarm control panels. Referred to as the Connected Building Module, the 4232CBM allows you to tie your VISTA security system in with a variety of third-party home automation controllers such as Control4, Crestron, Savant, Lutron, URC and Key Digital. These systems are connected using the Serial connection with RS232 or RS422 data protocols between the automation system and the alarm panel's ECP bus. For newer Z-Wave controllers without these antiquated serial ports, you may have to source an adapter from DB9 (serial) to USB or whichever connection your controller supports.

The 4232CBM requires RIS (Remote Interactive Service) to be supported and enabled on your VISTA series alarm panel. For example, the VISTA-15P and 20P will need to be revision 9.12 or higher since that is the earliest revision to support RIS. All Revisions of the VISTA-128BPT, V128BPTSIA, FA1660CT, and Rev 10.3+ of the VISTA-250BPT support RIS. All Honeywell panels that support RIS, only support a single RIS device. Since Total Connect 2.0 (interactive app for control and text/email alerts) requires RIS, you cannot setup TC 2.0 and use the CBM with an automation. It is one or the other. You may need to enable RIS in field *91 if not already enabled.

The CBM comes with a 4-wire harness that clips into the board of the device. The other end of harness requires 2 power (terminals 4 and 5) and 2 data (terminals 6 and 7) connections to be landed on the ECP bus on the VISTA panel. Use your panel's wiring diagram to confirm ECP connections.

Since it is an ECP device, it needs to be mapped to an open AUI slot. For example, the VISTA-20P has 4 AUI's on slots 1, 2, 5 and 6. By default, AUI 1 and 2 are enabled and mapped to parameter 1 to offer virtual control to partition 1 on the VISTA panel. We recommend you set the AUI for the CBM to parameter 5 to disable "auto-stay" so you can arm away remotely. You can find this setting in field *189 in panel programming.

Lastly, you will ned to make your serial connection to the home automation system. The CBM offers a DB9 (9-pin serial cable) connection that can be landed directly to a DB9 port on the controller or converted through the use of a third-party adapter.

Good afternoon, you can email us at and we can email you the PDF file.
Are there any published instructions for how to set this up on a Vista 20P?
Yes, we've seen it work with a VISTA-21iP before. It sounds like you have the right setup, but just to be sure what values do you have set for field 91 and 189?
Has anyone been successful in making a 4232CBM work with a Vista 21ip. I've got one I'm playing with to see if it will work with my HA system, but the power led is flashing (power on, not configured). RIS is enabled in *91 field, and the AUIs are enabled in *189. I've got three Tuxedo units in AUI1/2/4 and *189 of AUI 1[01], 2[01], & 4[01], leaving AUI3[05] for remote services. I did have TC2.0 operating at one point, but discontinued the service years ago. My Vista 21ip is firmware 3.13. Any thoughts?
The L5100-ZWAVE is not compatible with Homeseer but if you add the module to your L5200, you can use the Secondary Controller feature to send all Z-Wave devices tied into the L5200 over to the Homeseer. We have an FAQ detailing how primary/secondary controllers work online at
Hello I have a lynx touch 5200 I use homeseer If I add Honeywell L5100-ZWAVE homeseer will you detect the z-wave?
Yes, that is correct.
To be clear; the ethernet adapter on the 21iP would still work for internet monitoring with a 4232CBM, I would just be unable to get the TC 2.0 functionality correct?
Tristan, you can still do IP communication for alarm signals, it just keeps you from using Total Connect 2.0, this is because it acts as an RIS device, and you can only have one of those, so it's either the 4232CBM, or the AlarmNet communicator (for TC2).
I'm very confused here. Is there any way to get IP monitoring if you use this in your system? I'm wanting to combine this and a VISTA 21iP. I understand I wont have TC 2.0 features but can I still get ip based monitoring at all? Seems really strange that integrating this into an automation system would void the ability to get monitoring through IP.
Wireless would be much easier since you can just map the same serial number into each panel. When it comes to duplicating wired zones you may have to integrate 5800C2Ws: Basically wire the zones to the C2W. Then map the wireless zone to each system...Here are some videos: and FAQs:
What about using two panels ? Any way to integrate two vista 128 panels using the same wired contacts (about 50 zones)
This offers an RS232 connection so as long as you have an input for that on a controller it should work. You will need to build or find a compatible driver as well.
You have to choose between TC or CBM. These panels only support one or the other. Same goes for the 256BPT. Hypothetically you program same RF sensors to two different panels. Then you can use one for TC and the other for Crestron integration. I have not seen this done before but I do not see any reason why not.
Hello we have a Vista 128 and suing this to integrate with an existing Crestron Control System. Can the Vista 128BPT work with Crestron and also use Total Connect? It looks like it would not do both but wanted to make sure if there is any possiblity, even if it were to mean adding a second panel or 256 panel if that were possible.
Yes, you can certainly use the 4232CBM and an AlarmNet communicator. Without knowing the third party automation system you plan to integrate with, I can't speak about compatibility with that but I do know both units work together.
Can the 4232CBM be used in conjunction with a GSMV4G on a Vista 20P Panel?
