What is a Whole-House Controller?Whole-House Controllers:
Today's whole-house controllers use the X10 standard to control lights and appliances. Some go beyond X10 by using infrared to control TVs, stereos, CD players, etc. A whole-house controller can perform certain tasks based on
time-of-day, user commands via button presses, and other inputs such
as motion-detector trips.
The TW523 pops up wherever a third party manufacturer is transmitting (or receiving) X10 commands. Power Line Interfaces |

| The TW523 turns the X10 powerline commands into a serial TTL stream. When carefully matched with the zero-crossing signal (also from the interface), a microprocessor can decode the X10 commands. The TW523 also allows you to transmit X10 commands by "wiggling" the transmit line at exactly the right times. Note that these transmit and receive bit streamsare notRS232...or any other standard. Regardless of what you might hear elsewhere, you cannot reliably transmit or receive X10 commands directly from a computer's serial or parallel port; In addition to the TW523, you need some kind of interface box. | |||||||||
