G. OTHER REMOTE-LOCATION CONTROL
OPTIONS
Both IR and X10 devices require line-of-sight access to the IR signal
receivers. In some cases, this presents a problem for individuals
who need to access electronic devices that are not within their
visual field. There are three ways to accomplish this:
1. X10 wire transmission to a remote location
2. Infrared (IR) to Radio Frequency (RF) to Infrared (IR) trans-
mission
3. Infrared (IR) to Radio Frequency (RF) to Infrared (IR) to X-10
transmission
1. X10 Wire Transition to a Remote Location
As mentioned in a previous section, the X10 system broadcasts
through the house wiring. As long as the IR controller
(Powerhouse) is set to the same letter code as the X10 receiver,
the signal can be broadcast to any location that connects to the
house wiring. For example, the X10 receiver for “Unit 1” on the
Enhanced Display X10 menu could be located inside the switch
controlling the outside porch lights. If the upstairs bedroom con-
troller and this porch light receiver are set to the same letter code,
a user could turn on the outside porch lights from the upstairs bed-
room.
2. Infrared (IR) to Radio Frequency (RF) to Infrared (IR)
Transmission
A second way to access a remote location is to convert the infrared
(IR) signal into a radio frequency (RF) signal and then back into an
infrared (IR) signal. In this example, a TV in the living room is
turned off from the upstairs bedroom.
This transmission is accomplished by transforming the IR signal into
an RF signal using an RF Powermid® pyramid transmitter and
then back into an IR signal using a Powermid® pyramid receiver.
Other products, such as the Leapfrog® transmitter accomplish the
same end. Local electronics specialty stores and the internet fea-
ture lists of available products.
3. Infrared (IR) to Radio Frequency (RF) to Infrared (IR) to
X-10 Transmission
A third way to access a remote location is to convert the IR signal
into an RF signal and then back into the IR signal using Powermid®
pyramids. The receiver pyramid then broadcasts the IR signal to an
X10 controller (powerhouse), which converts it into an electronic
pulse that travels through the house wiring to an X10 receiver
switch. This switch opens the circuit of the electric light or appliance.
This setup is often used to open garage doors using an IR transmitter.
