I am not having any success integrating my Honeywell Vista 20p panel with the RadioRa 2 system using the 4232CBM module. I am using Lutron Application Note #488 to configure the Honeywell and RadioRa 2 system. For testing, On the Arm/Stay and Arm/Away trigger, I am trying to turn on a RRD-8ANS switch. It is not working. Over the weekend I spent over an hour with the RadioRa 2 Tech Support folks and it is still not working. It seems that the 4232CBM module is not communicating to the RadioRa 2 main repeater.
In troublshooting the issue, tech support had me establish a telnet session over the ethernet cable using putty to the main repeater, and the command #device,1,95,3 worked (light came on). I will test the same command using a RS232 connection to the main repeater as well.
One thing I noticed in the application note is that interface emulates a standard alpha keypad which I have assigned keypad address 17. In the 4232CBM documentation, it talks about using an address for the AUI keypad (touchscreen) in which I don't have available before I already have 4 tuxedo (touchscreen) keypads connected to my Honeywell system already.
