Philips said it couldnt work. Lutron Said it couldnt work. but I did it. I successfully extended the range of a RadioRA lighting system to control multiple buildings with a single press of a button.
using 4 RFX9600 serial controllers and 4 lutron Chronos systems. My clients are able, from the comfort of thier bed on the third floor of the main house, turn off a single light over 600 feet away in the Horse stables. also, I created a network to bridge 4 chronos' together, including the main house as a bridged system. 5 radio RA systems bridged to one touchscreen using rs 232 macros to hit one button on the TSU9600 (entertain) to turn on phantom buttons in the chronos to execute each entertain scene in thier respective system.
it was a 4 month process of trenching several Cat5 wires throughout the property, setting up a private network because of the security of the Clients existing network, building a new pool house AV system and rebuilding the Kitchen. all in all we are incorperating over 90 Radio RA dimmers, 4 auxilary repeaters, 4 chronos timeclocks, 3 TSU9600's, 4 rfx9600, and 1 FP1 fireball ipod server. pictures soon to follow. I was up there till 11:00 last night finishing it.

Big Thanks to Jim Patten and all the guys at AVAD southeast who was integral in making this project work. thier knowledge of the products was astounding.
