Hello all, I am investigating using a PLC (power line carrier) to send data = around a building. I looked at X-10, but it seems to be limited to on = and off. I looked at the devices (TW523) at x10.com. There is = something about an extended data code, but it specificaly says that the = OEM receiver can not receive those. Does anyone know of an off the shelf OEM module that I can use to = send data over the power wires withing a building? I can modify my data = format and speed on a whim, so anything is fine. The total length of = the data is about 3 bytes, but again thats flexable. =20 Thanks for any input, Shawn -- http://www.piclist.com#nomail Going offline?
