I used to work with X-10 in larger buildings. It would usually propagate to the next transformaer, and they had modules that could bridge around transformers as needed. I imagine you might have problems with hi amperage (1000 amp) power buses, because of low impedance, I am not really sure. -----Original Message----- From: Rob Bakker To: PICLIST@MITVMA.MIT.EDU Date: Tuesday, August 10, 1999 6:00 AM Subject: X10 stuff and PICs >Anybody know if there is a distributor in New Zealand/Australia who sells >X10 modules?
