X-10 Power Line Technology In Brief
The Smart House products uses the proven X-10 Power Line Carrier (PLC) technology as backbone for transferring of control/monitoring signal. X-10 is a communications "language" that allows X-10 transmitters and X-10 receivers or compatible products to talk to each other via existing electrical wiring in the building. The X-10 PLC technology transmits binary data over the power line using a 120 kHz signal burst for 1 ms at the zero crossing point of the AC sine wave.

Transmitters and receivers generally plug into standard electrical outlets although some can be wired in-line with the electrical devices. Transmitters send commands such as "on", "off" or "dim" preceded by the identification of the receiver unit to be controlled. This broadcast goes out over the electrical wiring in a building. Each receiver is set to a certain unit address, and reacts only to commands addressed to it. Receivers ignore commands not addressed to them.
Note: "X-10" is a trademark of X-10 (USA) Incorporated.

A Typical X-10 Power Line Carrier System
A PLC system primarily consisting of a transmitter and receiver. The transmitter transmits coded signals along the existing power line. The coded signal transmit the on/off/dim/bright/all on/all off command to the receiver. The received picks up the signal, execute the commands. All together 256 combinations of signal is possible thus enabling a single controller to control up to 256 receivers
Following is a general arrangement layout for the system. Future expansion of the system can easily be done by simply installing additional transmitter modules or receiver modules to the points to be controlled.
