Introduction

Thank you for selecting the MARC+ Remote Control System. It has
been designed for the utmost in convenience and reliability. Read
this owner's manual carefully to become familiar with the product
and how it works. The manual explains in simple steps how to
install, use, and care for your MARC+ System.

The MARC+ Remote Control System allows you to control virtually
any device from any room in your house, even outside — without
wiring your home!

With the MARC+ System, you can operate up to eight infrared­controlled Audio/Video components, such as TVs, VCRs, and
stereos, with one remote control. Additionally, the MARC+ System
allows you to turn on/off appliances and lights (and dim also), all
at the touch of a button.

From the MARC+ Remote Control, you can operate up to 100 X­10® Powerhouse™-connected lights and appliances. The X-10
modules are easy to install — just plug them into standard power
outlets.

The MARC+ System uses a small, hand-held Remote Control which
broadcasts radio frequency (RF) signals to the MARC+ Receiver.
Depending on the button you press, the MARC+ Receiver will take
one of the following actions:

• Replay “learned” infrared signals to control your audio/video
equipment,

• Send commands over the power lines to control your X-10
lighting and appliance devices, or

• Play a MACRO command to perform a sequence up to 10-steps.

• The “Auto-Source-Selection” feature make system operation
easy.

As with any radio control system, the operating range is limited;
this means that the MARC+ Remote Control can function only a
certain distance away from the MARC+ Receiver. Under typical
conditions, the MARC+ System will operate throughout an average
home and immediately outside it.

Parts Checklist

When unpacking your MARC+ System, make sure that you have the
following parts:

1. Vaux RC-8 RF Remote Control

2. MARC+ Receiver

3. Standard Antenna (25” wire w/ phono plug)

4. Power Adapter (12VDC, 200 mA)

You may also need some of these optional parts for your
installation:

• One X1 Powerline Interface (X-10 Interface module and cable)

• Up to four EC-1 Infrared Emitter Cables, or EC-2 Dual Emitter

Cables

• Additional RC-8 RF Remote Controls for other rooms

• ANT-3 Folded Dipole Antenna, or an APA-1 Antenna Preamp
to
increase RF reception range

5

Installation

(NOTE: For the purpose of this installation the MARC+ Receiver will
be referred to as the Receiver; the Vaux RC-8 RF Remote Control
will be referred to as the Remote Control. An audio receiver or
infrared remote control will be specifically referenced to as such.)

The rear panel of the MARC+ Receiver has the following
connections:

1. 12 VDC Power Adapter (2.1 mm, center negative)

2. Antenna Connector (phono jack) — Standard wire
antenna connects here, or, optionally, remotely-located antenna(s),
such as the ANT-3 Folded Dipole, may be connected via RG-59 or

RG-6 coaxial cable, and the appropriate adapter.

3. Four Infrared Emitter Cable Connectors (3.5 mm phone
jack) (Xantech®-compatible, center positive)

4. X-10® Interface Module Connector

("telephone-type" modular jack)

The bottom of the MARC+ Receiver also has a recessed pushbutton
RESET switch (Caution: pressing the Reset button will restore
factory settings and erase all infrared codes).

1. Place the Receiver beside your audio/video components. For best
RF reception, locate the Receiver as high as possible, and as far as practical
from cables and metal cases. Avoid placement close to large-screen TVs,
computers, or fluorescent fixtures — these devices generate RF noise which
can reduce range.

2. Attach IR emitters over each audio/video component's infrared (IR)
sensor window. The emitter affixes with a small section of peel-off, double­sided, removable adhesive tape. Plug the connector end of the emitter cable
into one of the four rear-panel emitter jacks on the Receiver.

The Receiver has four connectors (3.5 mm phone jacks) on
the back panel for attaching infrared emitter cables. Each single
emitter can control one audio/video component. Optionally, you
can use dual emitters to control up to 8 A/V devices.

6

(NOTE: You may also choose to use a “Room Blaster”
instead of, or in addition to, the emitter cables. A Room Blaster
can transmit the invisible infrared (IR) signals across a room to a
wall of components; this provides more installation flexibility, but
the signals can also get blocked by people or objects in the IR path.

3. OPTIONAL: X-10® Lighting/Appliance Interface Module

a. Plug one end of the X-10 Interface Cable into the "telephone-type" jack
on the back of the Receiver.
b. Plug the other end of the X-10 Interface Cable into the "telephone-type"
jack on the X-10 Interface Module.
c. Plug the X-10 Interface Module into an unswitched standard electrical
outlet. This allows the MARC+ System to send commands over the
powerlines to control X-10 devices.

4. Plug the Antenna into the Receiver and straighten the wire up and
away from cables and other metal.

5. Connect the Power Adapter to the Receiver and plug into an
unswitched standard electrical outlet.

6. Install the Remote Control's batteries: The RC-8 Remote

Control uses 3 “AAA” batteries to power it. Alkaline, Heavy-Duty
Carbon, or rechargeable NiCad batteries may be used. These
batteries will last up to 6 months under normal conditions. Be
certain to observe polarity markings when installing batteries.
Remember to always dispose of batteries at a recycling center;
more information about battery use and disposal may be found on
page 3 of this manual.

When changing the batteries, lay the RC-8 keyboard-down on a
flat surface; protrusions on the case prevent the keys from being
pressed. Remove the old batteries and replace with new batteries
within one minute. This process will ensure that the user­selectable settings are not changed. If you want to restore the
factory settings, remove the old batteries, press a key, and let the
RC-8 sit for a minute or so before installing the new batteries —
the red light will flash twice to indicate that factory settings have
been restored.

7

USING A VAUX RC-8 REMOTE CONTROL

The Vaux RC-8 Remote Control supports the IR commands for up
to 8 A/V components, as well as up to 100 X-10-connected lights
and appliances.

When the batteries are first installed, the RC-8 will use the "factory
settings" for the programmable features it stores. Upon battery
insertion, the red light flashes twice to indicate that the factory
settings have been loaded. The user may at any time change these
settings.

The factory settings are:
Current A/V Device: 1

( Tuner )

Default Light Group: 1

( X-10 House Code A )
Default Security ID Code: 1070
Default Zone: 1 (not used by the MARC+)

Batteries should be changed when the low-battery indication is
given, that is the red and green lights flashing simultaneously
when a button is pressed. Although you may continue to operate
the RC-8, operating range will be reduced and remaining battery
life is short.

8

The RC-8 has a three-position slide switch which selects the
operating mode; Audio/Video, Lights/App, or MACROs.

The Audio/Video mode is used to operate infrared-controlled
components whose control codes have been learned by the MARC+
Controller.

The Lights/App mode is used to operate X-10 connected lights and
appliances. The MACRO mode is used to invoke up to a 10-step
key sequence by using the number pad (0-9), for ten different
MACROs.

There are several special buttons on the RC-8: the SHIFT button,
eight Device buttons (Tuner, CD, etc.), the Sec button, the Learn
button, and the Zone button.

In the Audio/Video mode, the “keyboard” buttons correspond to
the currently-selected “Device”. These eight separate keyboards
are also referred to as “pages” of infrared control codes. There are
30 programmable buttons which access the infrared codes for the
currently-selected device. That is, each of the eight selectable
Devices has a 30-button "keyboard" (or page) for a total of 240
infrared control codes.

Besides the standard buttons (FF, Play...) there are four general­purpose “function” buttons, F1 - F4, which may be used for less­frequently used infrared commands, for example, PIP, VCR
tracking, surround modes, etc.

One way to change the Device you are controlling is to press the
Shift key, followed by one of the Device buttons (e.g.: Shift-CD).
This changes the Current Device which the RC-8 is ready to
control, without transmitting any commands to the MARC+
Receiver.

A second way to change the Current Device is to simply press the
desired Device button (e.g.: CD). This changes the Current Device
which the RC-8 is ready to control, AND transmits a special
“Source-Change” command to the MARC+ Receiver. Each of the
Device buttons has an IR code associated with it, which is used to
store the source-selection commands for your A/V receiver. You
simply press CD: the A/V receiver automatically selects the CD
input, and the RC-8 keyboard now accesses the CD’s controls.

Infrared Learning

1. Slide the mode switch to “Audio/Video”, and then Press and hold the
Learn button on the Remote Control for 2 seconds until the green

light on the Remote Control illuminates, then release. When the
button is released, the yellow Learn light on the Receiver will
illuminate. You are now in IR learning mode.

2. Select a Device: Press Shift-Device for the component you
are about to teach to the MARC+ System (for example, Shift­Laser). You may change the Current Device at any time; you have
eight separate “keyboards” (or IR pages) to program.

3. You are now ready to map all of the buttons from your existing infrared
remote control(s) to the buttons on the MARC+ Remote Control.

You can learn as many buttons as you wish — one or all. If you
want to change a button that already has been taught, just learn it
again. It will replace the old command with the new infrared
command. All of the commands are stored in the Receiver, which
has a battery backup — you may unplug it without your codes
being lost.

Press the button on the MARC+ Remote Control that you want to teach

(for example, Ch Up); the green Data light on the Receiver will go
on, and the yellow Learn light will go off.

4. Hold the infrared remote control up to the sensor window on the front
of the MARC+ Receiver (approximately 2 to 4 inches away) and press

and HOLD DOWN the button — that you want to learn — on your existing
infrared remote control (for example, Ch Up) until the yellow Learn light

on the Receiver illuminates, then release. Note: the green Data
light on the Receiver will flash as the code is being learned.

IMPORTANT: You must HOLD DOWN the infrared remote
control button, while you are learning the code, until the yellow Learn light
on the Receiver illuminates. This may take a second depending on the type
of A/V device.

If there has been an error while learning, the red Error light on

the Receiver will blink; repeat steps 2 through 4 until all of the primary

10

device buttons have been learned. You may change the Current
Device setting at any time; you have eight separate "keyboards" to
program.

Note: If you wish to have a global button (e.g. Volume, Mute,
Power...) which is always available regardless of the Device page
you are in, simply program the same code in all eight device pages.

5. To program the eight special “Source-Change” codes, press a Device
button (e.g.: Laser) when the Receiver's yellow Learn light is on.
Then program this location with the appropriate source-select
code for the A/V receiver. Repeat for the other Device buttons.

6. To exit IR Learning mode, press and hold down the Remote Control's
Learn button for approximately 2 seconds until the Remote Control's

Green light goes on, and then release the button. Note: You may
exit Learn mode only when the Receiver's yellow Learn light is on.
When completed, the green Data light flashes and the yellow Learn
light will go off.

11

MACRO Programming

Multiple command MACRO support allows you to define one­button sequences, for example, adjust room lighting, lower the
projection screen, power-up the laserdisc, and play. There are Ten
10-step MACROs available using any combination of audio/video
IR command, X-10 for light control, even time delays (using X-10
commands). MACROs are stored in the Controller, which has
battery back-up.

There are 10 different MACRO buttons available using the number
keypad (0-9).

a. Slide the Mode switch to the Macro position.

b. Press the Learn button (do not hold down — if held down,
system will go into Infrared Learning Mode, not MACRO Learning).

c. Press and hold down the MACRO button that you would like to
program (for example, 1) for 2 seconds until the Green light on the
RC-8 is on, then release. The Controller's Learn and Data lights
will illuminate.

d. In the desired operational sequence, slowly press the sequence
of buttons, one right after the other waiting a second between
button presses for the data transmission to complete (lights on the
RC-8 will flash during transmission). The Data light on the
Controller flashes off briefly as the button-press is added to the
MACRO's sequence. You can program up to 10 different
audio/video IR and/or X-10 steps per MACRO button.

Example: • slide to Macros, press Learn, press/hold 2, release

• slide to Lts, press 2, 3, On (B3 On) (1 step)

• press VolDn, VolDn, VolDn (dim about 50%) (3 steps)

• slide to A/V, press Laser, press Play (2 steps)

• slide to Macros, press any number key to exit

MACRO Tip: if you wish to insert short delays between commands,
enter an unused X-10 function (e.g. H1 OFF, if H1 is not used in
your house) to obtain approximately one second of delay per X-10
command.

12

MACRO Tip: a “System On” Macro is handy, but many A/V devices
have a toggling power command and can lead to synchronization
problems. Use an X-10 Appliance power strip to power these
components; in the Macro, first turn the module Off, then On
(devices now in standby), followed by all of the component IR
power commands.

Default Lighting Group (X-10 House Code)

The MARC+ System allows access to 100 lights and appliances
using a 2-digit operation (00-99), but also provides a shortcut 1­digit operation to control up to 9 X-10 modules that are used most
frequently; these nine modules must have the same House Code
and will use Unit Codes 1 to 9. The House Code used in 1-digit
operation is stored in the RC-8 Remote Control.

When batteries are first inserted into the RC-8, it is initially
programmed with a House Code Factory Setting of "A". For initial
1-digit X-10 Operation, a House Code of "A" will automatically be
used and you do not have to specify a House Code.

To set a new default House Code for 1-digit operation:

a. Press the Learn button, then press the Shift button, then
press and hold down the Zone button until the Green light on the
Remote Control is on, then release.
b. Press a digit (0 through 9), corresponding to the desired
default House Code. This will be saved until it is changed or reset.

Security ID Code

The MARC+ System can be set to a unique identifying number,
not unlike dialing up a number on a garage door opener. This
allows systems to exist in adjacent houses, or multiple Vaux
Systems to be installed within one house. There are 10,000 code
combinations possible. Only power one Receiver at a time when
setting SecIDs.

Before you begin, make sure the MARC+ Receiver is plugged into a
standard electrical outlet and has power. Also, make sure that you are within
transmitting distance.

a. Press and hold down the Sec button on the RC-8 Remote

Control for two seconds until the Remote Control's green light is on,
then release.

b. Press 4 buttons corresponding to the 4-digit security code
desired (0000 through 9999).

c. For verification, press the new 4-digit security code (0000
through 9999) again. Once verified, the command to change the
security ID code will now be transmitted to the MARC+ Receiver
and the green Data light on the Receiver will flash.

If an incorrect button is pressed during the second code
entry, the red Error light on the Remote Control will flash to indicate
that the security code was invalid; please start all over again. No
command will be sent to the Receiver.

If there is an error during transmission and the Receiver
does not receive a valid security id code change, the red Error light
on the Receiver will flash. Or, possibly, if you are too close to the
Receiver, no light will flash. At this point, the Remote Control's
security id code has been changed, but not the Receiver's. The
Remote Control will need to be changed to match the Receiver
(start from step a. and enter the previous setting — the command
will be ignored by the Receiver) or reset to the factory settings.

IMPORTANT: If for some reason, either the Remote Control's or
the Receiver's security id code changes, but not the other, reset to the factory
settings of 1070; see page 23.

Operation

Audio/Video Operation

1. Slide the Mode switch to the Audio/Video position.

2. Select the Device you wish to control by either:

• pressing a Device button (e.g.: Cab/Sat) to change the

Current Device AND use Auto-Source-Selection, or

• pressing Shift-Device (e.g.: Shift-Cab/Sat) to change the

Current Device without changing any source selection.

3. Press the button for desired operation (e.g., Vol Up).

Note: You may control system power individually over each
component, or you may program MACROs to turn your entire
system on and off.

MACRO Operation

1. Slide the Mode switch to the Macro position.

2. Press a digit key (0-9) corresponding to the desired Macro.

15

Lights/Appliances (X-10) Operation

Controlling your lights and appliances can be performed by
using either the 1-digit or 2-digit operation. With the 2-digit X-10
operation, you can control up to 100 lights and appliances. The 1­digit operation is used to reduce the number of keystrokes for the
lights/appliances control for up to 9 X-10 modules that are used
most frequently and have the same House Code.

1. 2-digit operation:

a. Slide the Mode switch to the Lts/App positions

b. Press a digit (0 through 9), corresponding to the desired
House Code.

d. Press the On or Off button to control the X-10® Module.

(NOTE: In order to dim or brighten a light, the light must

first be turned on and then dimmed/brightened. This an X-10-

16

defined operation. See Steps 3 and 4.)

Example of 2-digit X-10® Operation:

For example, either a lamp module or an appliance module set
to a house code of "D" and a unit number of "5", would be
addressed by pressing the two-digit code, 4 5. An X-10 module
set to a house code of "F" and a unit number of "9", would be
addressed by pressing the two-digit code, 6 9.

2. 1-digit X-10 Operation (Default House Code Used):

The 1-digit operation can be used in addition to the 2-digit
operation; it is used to reduce the number of keystrokes for the
lights/appliances control for up to 9 X-10 modules that are used
most frequently and have the same House Code.

The MARC+ System is initially programmed with a House
Code Factory Setting of "A". For initial 1-digit X-10® Operation, a
House Code of "A" will automatically be used and you do not have
to specify a House Code.

If you wish to use a different House Code, other than "A", you
must change your Default House Code — See previous section.

1. 1-digit operation:

a. Slide the Mode switch to the Lts/App positions

b. Press a digit (0 through 9), corresponding to the desired X­10 Unit Code.

Use the zone mapping provided on the rear label of your

17

MARC+ Remote Control for the 1-digit X-10® operation. This
gives you a quick reference guide.

Zone "0" commands all modules, on the default House Code,
to respond to the X-10 "All Lights On" and "All Units Off"
commands.

c. Press the On or Off button to control the X-10 Module.

(NOTE: In order to dim or brighten a light, the light must
be turned on, then dimmed, then brightened. This an X-10
defined operation. See steps 3 and 4.)

Example

With the 1-digit operation method, the factory-setting house
code is set to "A". For example, either an X-10 module placed in
the Living Room should be set to a house code of "A" and a unit
number of "1". A module placed in the Dining Room should be set
to a house code of "A" and a unit number of "2", etc.

If you hear a noise at night, 0-On turns on lights in the whole
house.

3. Dimming/Brightening Lamp Modules:

In order to dim a light, the light will be first be turned on
and then dimmed. Only the last module which was turned on is
affected. Actually, the last light turned Off will also dim (from full
bright), but will not brighten from full off. This an X-10 defined
operation.

Note: Macros can be used to preset modules On and fully
dimmed. They can then be brightened from this pseudo-off point.

Note: Appliance modules do not respond to the Dim/Bright
commands, since they use relay switching.

a. Slide the Mode switch to the Lts/App positions

b. Press Chan Up/Down, or the Vol Up/Down buttons, and hold until
the lamp is dimmed/brightened to the desired level.

18

Note: The Dim/Bright operation does not apply to the "All Lights"
zone; this is an X-10-defined operation.

19

Maintenance

The MARC+ System is designed to be maintenance-free, but it
does contain sensitive electronic parts. Treat it with care to assure
best performance.

Avoid Rough Treatment
Avoid dropping the MARC+ Remote Control and Receiver. Use the

How do I find the IR sensor on my audio/video components?

Place each emitter on front of the audio/video equipment's infrared
(IR) sensor window. The emitters have double-sided tape to allow you to
fasten them. If your audio/video component has an infrared (IR) remote
control, it will have an IR sensor window, which is typically located on the
front panel. It is usually a small dark or red window and may be labelled
“IR Sensor.” If you cannot locate the IR sensor window, refer to your
audio/video equipment owner's manual. If your owner's manual does not
indicate the location, you can determine the location by repeatedly
covering small areas of your audio/video equipment's front panel with a
piece of cardboard and using your remote control. Hold the cardboard
close to your component and hold your remote control approximately one
foot or more away from (and pointed towards) your component.
Remember, infrared signals are invisible beams of light; a solid object in
the path of the IR signal will prevent your component from seeing the
remote control signals. Once your audio/video equipment is not
responding to the commands from your remote control, you know that
you have covered — and found — the IR sensor window.

How can I maximize the operating range?

Radio system operating range is dependent upon many factors. The
MARC+ Remote Control sends radio signals throughout the house to be
picked up by the MARC+ Receiver. In order to obtain maximum range,
the location of the Receiver is important. In some cases, installing the
Receiver on the second floor will provide greater range than a ground
floor installation. Reception is also affected by atmospheric conditions,
and by metal construction which acts to shield radio signals (for example,
aluminum siding, insulation foil backing, and heating ducts). Of course,
you can't easily relocate your audio/video components to suit MARC+
reception, but you can keep in mind that a higher installation site for your
MARC+ Receiver would be desirable. Also, try to keep the Receiver's
Antenna Wire in a vertical position and away from other cables and metal
cabinets where possible. Alternate antenna systems may help also.

How do I reset my remote control and receiver back to factory settings and clear the
memory?

You can achieve this by removing the batteries from the Remote
Control for about a minute; this resets the Remote Control's Security ID
Code to "1070", and the factory setting X-10® House Code to "A".

For the Receiver, find the small hole in the bottom of the case and
press the recessed pushbutton with a pointed instrument, such as a pen,
holding for approximately one second until the green Data light flashes;
this will erase all of the infrared and Macro codes, as well as reset the Security ID Code
to "1070".

Troubleshooting Guide
I press a button and nothing happens except:

1.) nothing — no lights on the Remote Control or the Receiver flash.

Dead batteries — install new batteries in the Remote Control.

2.) the red Error light on the Remote Control flashes and no lights on the Receiver
flash.

You have pressed an invalid button or sequence of buttons.

3.) the green light on the Remote Control flashes, but no lights on the Receiver flash.

The Remote Control has sent a valid command, but the Receiver has not
sensed it; the cause may be one of the following:
a.) You may be located too close to the Receiver (less than 2-3 feet
may overload the Receiver.)
b.) Your Security Identification Codes in your Remote Control and
Receiver may not match. Reset the Remote Control to factory settings by
removing its battery for approximately a minute. Reset the Receiver to
factory settings by pressing the button on the bottom of the Receiver for
one second until the green Data light flashes; this will also clear out the
infrared memory in preparation for a new learning session.
c.) You may be having interference or other transmission problems;
for example, you may be located in an office that has metal studs, or
d.) You may be located out of range of the Receiver.

4.) the green light on the Remote Control flashes and the red Error light on the
Receiver flashes.

The Remote Control has sent a valid command and the Receiver has
sensed the command, but the Receiver considers it an invalid command.
Your problem may be one of the following:
a.) If you are sending X-10 commands for lights and appliances, then
you may not have the X-10 Interface Module connected (or its outlet
switched off), or
b.) If you are sending X-10 commands, you may have a defective X­10 Interface Cable, or
c.) If you are sending infrared commands, you may have not
programmed the Receiver with an infrared code for that device's button.

5.) the green Data light and the red Error light on the Receiver flash together.

The Security ID Codes do not match.

6.) the green light on the Remote Control flashes and the green Data light on the
Receiver flashes, but still no response.

The Remote Control has sent a valid command; the Receiver has sensed
the command and also has qualified it as a valid command. The Receiver
is also acting on the command — either sending signals out the infrared
emitter connectors or out to the X-10 Powerline Interface Module.

If you have pressed an audio/video command, your problem may be one of the
following:

a.) You may have the emitter cable placed in the wrong area on your
A/V equipment. You can verify that the codes are being emitted by
looking on the back of the MARC+ Receiver and seeing the green
diagnostic light flash. Check the section in your Owner's Manual on "How
do I locate the A/V equipment's infrared sensor."
b.) You may have not programmed the infrared codes into the
Receiver properly. Try learning the infrared code again, making sure the
light inside the MARC+ Receiver's window is flashing brightly; you may
need to hold the infrared remote control closer or further away depending
on the strength of the signal.
c.) You may have a defective emitter cable (or connector). You can
verify this with a camcorder if one is available to you. While infrared light
is invisible to the eye, you are able to see the infrared flashes at the emitter
end (it's brightest on the front of the emitter) through the viewfinder of a
camcorder. If you have more than one emitter cable, you may be able to
isolate the defective one by switching cables.
If you have pressed an X-10® command, your problem may be one of the following:
a.) The X-10 module is not set to the correct House and Unit codes —
valid module settings are listed in X-10 Operation section of your Owner's
Manual.
b.) You are expecting some action which is not allowed by X-10®.

Example 1: the Dim/Bright operation applies only to the last

module accessed;

Example 2: the Dim/Bright operation does not apply to the All

Lights zone;

Example 3: if you have dimmed a light completely down, you

cannot command it ON and expect full brightness (it thinks it is
already on at a low level; you must either brighten it, or first turn it OFF,
and then ON). These are X-10-defined operations.
c.) Even though the Receiver checks for the presence of the X-10
Interface Module, you may still have a defective cable. The Interface
Module has a red light which is normally on — if your interface cable is
good, this red light should flash off briefly as X-10 signals are being sent
to the power line.

d.) You may not be able to send an X-10 command to some outlets in
your house — if you can control an X-10 module in the same room as
your MARC+ System, but the same module does not respond when placed
in its final destination, the cause may be:

Example 1: you have placed the module in an outlet which is switched

off — turn it on;

Example 2: you have a very large house and the module is located too
far from the X-10 Powerline Interface Module which is sending the
commands — there are X-10 signal boosters available from some
suppliers;

Example 3: you have discovered that X-10 signals do not always get
over to the other half of your powerline — if you can access the module
when a 220 Volt appliance (such as a dryer or stove) is turned on but not
when it's turned off, this is an X-10 subtlety — there are coupler devices
available from some suppliers.
