Helpful Tools
If you’re investing in home automation, there are a few tools that will make your projects run smoother:
Maxi-Controller
This plug-in transmitter has the ability to send individual PLC commands. The but-
tons are separated into Addresses and Command functions. To use this controller,
you have to press the address (for example, “5”), then the command (ON, OFF,
BRIGHT, etc.). Many of the features found in Smarthome products need to be pro-
grammed with individual button presses. Using a controller that sends the address
and command with one button press will not work. For more info visit:

Signal Meter
This is an invaluable tool when it comes to installing and diagnosing
problems. By knowing the signal’s strength at a specific location, you
can make sure that the signal will always trigger that module.
Generally, it is ideal to have at least 100mV at each location.
Conservative installers will want even more; perhaps 250mV just in
case the homeowner installs a new big-screen TV after final installa-
tion. The extra margin will still give the receivers enough signal
strength to be reliably triggered. These units can also be used to
measure the effects of signal absorption mentioned earlier. Plug in
the signal meter and measure the signal’s strength, then unplug any devices that are plugged into that
and nearby outlets. If 10% or greater change is observed, install a filter (like FilterLinc
TM
) on that device.
Voltmeter or Voltage Tester
During the installation of a home automation wall switch or controller, it may be necessary to identify
the wires inside the wall box. Knowing for sure which wire is the HOT or LINE wires can reduce the
guesswork when installing a single switch and it is absolutely necessary when working with 3-way light-
ing circuits. A voltmeter is ideal for this application. Many of the digital models can also read current
so you'll know how much power is being drawn by the switch’s load.
A simpler measurement tool, available at most home improvement centers, is a voltage sensor. This
device, often costing less than $20, can sense voltage when placed near a wire. The tip of the voltage
sensor can tell if voltage is on the wire without touching the bare copper conductor or breaking the
insulation.
When using these tools, be certain to read and understand the safety instructions. Often
when these tools are used, the power to the circuit will need to be turned on. When working
around live electrical wires, take your time and concentrate on the task.
Helpful Hints for New Construction
By design, X10 (also known as PLC) equipment does not need much in the way of special wiring. The
following are six items we recommend for all homes with PLC installations:
1. Ask the builder or electrician to run the neutral wire to each wall switch location. This wiring may be
a code requirement or a regular practice in your area, but unless explicitly specified, it may get omitted.
Most SwitchLinc Dimmers and all KeypadLinc Controllers require the neutral connection.
2. Specify the installation of deep J-boxes in all locations where PLC switches, receptacles, or transmit-
ters will be used. While all PLC products fit in the spacing offered by all North American electrical
boxes, the deep models have extra working space and make the installation go a little easier. Deep
boxes only costs a few cents more than normal depth models. Look for single gang boxes that are
22cu or higher (cubic inches) and double gang boxes that are 36cu. or higher.
3. If the automation switch is dimming-enabled and is going to be controlling 400 watts or more, do
not place insulation around the wall box and consider using metal junction boxes. Dimmers that con-
trol high loads will dissipate heat, which may be felt through the switch faceplate. Metal boxes will
more efficiently draw out the heat and spread it over all the surfaces of the box. By keeping wall insula-
tion a few inches from the box, free air will help move the heat away.
