The Transceiver Module (sold separately) receives radio frequency
(RF) commands from the UR78A Remote to operate a lamp or
appliance plugged into it. The Transceiver Module also passes on
commands over your house wiring to control other X10 modules (also
sold separately). Note that unlike the Lamp Module you cannot dim
or brighten a lamp connected to the Transceiver Module.
You should locate the Transceiver Module centrally in your home for
maximum range when controlled by the UR78A Remote.

Each Module has a specific address made up of a House Code (red
dial on the face of the Module) and a Unit Code (black dial on the
face of the Module).
Addresses are set on the Module by turning the two dials on the front
of the Module to the desired letter and number (using a small
screwdriver or a coin). The House Code is selected from the letters A
through P, and the Unit Code is selected from the numbers 1 - 16.
The Controller first sends an address
and then a command on the AC
power lines. Only the Module with a
matching address will execute the
command. If more than one Module
has the same address, both Modules
will execute the command.

The UR78A remote can also control lights and appliances around
your home when you purchase additional X10 accessories (See
pages 24 and 25).

The first thing you need to understand is that there
are two different devices you need to control your
home; Controllers and Modules. Any light or
appliance that you want to control is plugged into a
Module and that Module is then plugged into a
standard AC outlet.
Modules receive commands from Controllers.
Examples include the Lamp Module (sold
separately). The Transceiver Module (also sold
separately) is another example (although it also
doubles as a controller as described later).
Controllers are also plugged into standard wall
outlets and send commands to Modules over your
existing electrical wiring in your home without
affecting your electricity in any way.
The Transceiver Module works as a controller when it is
used with a remote control such as the UR78A Remote.
When the Transceiver Module receives a command
from a remote it sends digital signals over your
existing house wiring to a Module which receives the
signals and executes the command.
The remote uses radio frequency (RF) signals to send
commands to the Transceiver module. RF signals
can go right through walls, so you can use the
remote to control lights or appliances from
anywhere in your home.
