so an integrator walks into a house.....
I received a call from a potential (new) client and he tells me he bought a 14k sq foot house with what looks like Lutron lighting and wants to know if I can come by. So I go over there and he has 22 dimmers on a classic RA system. I go over/through his house from attic to basement and all I can locate is a RA-RS232 interface. I tried all on/off from there and all of the lights work as they should. For the life of me, I can not find a/the main repeater (or is it a master controller?) anywhere.
I've never worked with classic RA before so I'm hoping someone can help me with:
1. Can a classic RA system function with just the RA-RS232 interface or does it need the main repeater/master controller?
2. If a main repeater/master controller is required, how the heck can I locate it? Seriously, I spent hours trying to find it and could not locate it anywhere; is there a way to make it beep or something else (catch on fire or glow) to help ID it?
3. Client would like some scenes; it appears that there are keypads available for classic RA so that should be ok. But how does one map the dimmers so that I know what dimmer goes to what load? If I understand the protocol, each control (dimmer/switch) has an ID..how do I map that ID so I can assign it to a scene?
thanks for any/all help
