CHAPTER 5: X-10

Introduction

X-10 signals are transmitted over the 110VAC power lines within the house. These signals are used to

control equipment located throughout the house. The controller provides the following X-10 features and

capabilities:

• Can receive and transmit all X-10 commands.

• Can communicate with two-way X-10 thermostats from RCS, use preset dim commands with PCS

lighting modules, LM14A modules, and Leviton 6381 switches, and read the status of two-way X-10

lights. Also supports lighting "scenes" with newer X-10 devices.

• Maintains a state table showing the On/Off state and level of all 256 X-10 addresses (modules).

• Can be configured to automatically perform a set of actions when any On or Off signal is received

from another device.

• Can “refresh” an individual module or entire house code with a single command.

• Can perform actions when a sequence of X-10 signals is received..

• Module states can be used as conditions in If-Then and If-Then-Else statements.

• Module states can be viewed and changed from the video screen system.

• Modules can be set to specific states in the event of a power failure.

• Modules states can be read and changed from the serial interface.

Throughout this manual, we refer to X-10 “modules”. There are many types of modules:

• Wall switches to control lights

• Plug-in appliance modules (both 110VAC and 220VAC) into which you can plug other devices

• Relay interface modules that can open or close relay contacts when a specific X-10 code is received

• Powerflash modules that can sense opened or closed contacts and transmit an X-10 code in

response

• Chime modules

• Thermostats which respond to X-10 commands

• And others ...

As you can see, there are a wide variety of X-10 compatible items available. We use the term “modules” to

refer to any device which can receive or transmit X-10 signals.

Controller X-10 Operation

The controller constantly monitors the AC power line in your home, checking for X-10 signals. It uses the

TW-523 (or equivalent) Two-Way Power Line Interface device manufactured by X-10 (USA) Inc. for this

purpose. The X-10 code format is patented, and the TW-523 or similar device must be used for this

interface. A TW-523 is provided with the controller. Any X-10 signal that is detected on the AC power line

by the TW-523 is passed on to the controller.
