I have just started looking at the RTI keypads and when they are engraved and all fixed up, I will have say it is very impressive look. What parts are involved in a typical system to control RadioRa or say UPB? Could a processor handle a house full of keypads? What physcial connections are made at each keypad? I would assume with upb that you would just use 232 to CIM to fire links confingured with Upstart? but how do the keypads communicate to the processor? How is it configured with RadioRA? Could you remote the RA switches and have RTI keypads on the wall through the whole house? Thanks for any comments.

I can not speak for UBP but RA and the RK1s can be used very easily.


Connect the RK1 to the CB4 and the CB4 to the RP6. I believe this configuration would allow 8 RK1s (4 on the ports from the CB4 and 4 from the slave output of the RK1s themselves). This would be scale able by adding more CB4 to the system.

CM232 to RA-232 module


Maybe with carefull planning but I personally would be looking at a diffrent product, hardwire solution, if this is going to be a new build

Thanks for the info.

Absolutly, you are limited on the number of scenes if you use the RA-232 or the RA-IR, I would recomend going for the Chronos if the budget is there. On the RTI side the RP6 is what you'll need untill the XP-8 comes out, then it, along with some of the other new stuff will give you 2-way communication with the RA equipment.

I've used the RTI keypads to control UPB lighting in a HAI system which worked perfectly. It's a good system if you are looking to do whole house automation (lighting HVAC and some models even have security and CCTV) but the panels allow you to make up your own RS-232 commands that can do anything from turn one light off, to setting temperatures, arming the alram and throwing relays to close your garage doors with one button press. It's a fraction of the cost of a crestron automation system and can do the same things for automation. Your just need a RP6 and CM-232 module.

Is that accurate? I thought Chronos and the RA-232 both have 15 phantom buttons to assign to scenes.
