Niles Audio MS-200 Owner's Manual
such as “CL-2” or “CL-3”. Consult your Niles
dealer, building contractor, or local building and
inspection department if unsure about which type
of wire is best for your application.
MS200 Mounting Location
Locating the MS200 in the center of a room
usually results in the most even IR receiving
coverage, especially if the room is square
shaped. Rooms that are L-shaped or long and
narrow require more careful consideration. With
these types of rooms, installing the MS200 closest to the primary location of the user will
ensure the best performance.
The MS200 is designed to surface-mount almost
anywhere. Convenient mounting locations for
the MS200 include:
• On the front panel of a television set, facing
the viewer.
• On the front surface of a wall, a cabinet,
an appliance, or a speaker grille.
• Behind a speaker grille (speaker grilles typically
reduce the effective range of an MS200 to 15').
Receiving Range and Pickup Angle
The receiving range of the MS200 will vary
according to the IR output strength of the remote
control being used. Remote strength varies
among brands by the number and size of the
batteries used, and how many IR emitters the
remote has. For example, remotes that operate
on two small AAA batteries and have only one
IR emitter are generally not as strong as remotes
that use the larger AA size batteries and have
two emitters. Tests with various manufacturers'
remote controls have shown that the operating
range can vary from a minimum of 18 feet to a
maximum of about 30 feet. The IR pickup angle
of the MS200 is 30° off-axis (horizontal and vertical) at 18'.
Infrared signals travel essentially line-of-sight.
They will not pass through or around solid
objects. Do not rely on an IR signal being able
to “bounce” off a wall or reflective object to the
MS200.
Avoiding Electrical Interference
Avoid locating the MS200 near any potential
sources of Electro-Magnetic Interference (EMI),
The most common sources are:
1. Light dimmers or variable speed controls for
ceiling fans. These controls emit more interference when turned down halfway. They
emit little or no interference when turned up
all the way (brightest or highest position).
2. Large appliances (air-conditioners, pumps,
motors, compressors; etc.).
3. AC line noise (noise brought into the system
via the wall outlet connected to the main
system unit).
Concealing the wire
If you are installing the wire into an existing
wall, take time to consider any possible obstructions which may be hidden inside the wall, such
as wood or metal studs, electrical, telephone or
other types of wiring, plumbing, AC or heating
conduit, old wall safes, etc.
If the MS200 cable needs to pass through any
cabinetry (or other obstruction) drill a hole
where the cable will run. Make sure the hole
accommodates the width of the cable.
Using the MS200 with the Intellipad Ci system.
The MS200 is fully compatible with the Niles
Intellipad Ci line, follow the wiring instructions
in Figure 4. For specific information see your
Intellipad Ci manual.
INSTALLATION
Determine a mounting location for the MS200.
If there is a potential source of EMI near the
proposed mounting location (e.g near an electrical dimmer) you must test to find the best (interference-free) position before mounting the
MS200 in place.
INTRODUCTION
The MS200 IR sensor is designed for use with
the Niles infrared extender systems.
Installed in a remote room location, the MS200
receives the IR commands transmitted from your
existing hand-held remotes in that room. The
commands are carried via a category 5 cable to
your A/V equipment in another room, and
instantly “repeated”.
The MS200 is compatible with all current Niles
infrared systems. It may be used along with, or
as an alternative to, the Niles TS100, MS100,
WS100, CS100 and MVC100IR sensors or the
IntelliPad
®
.
The MS200 is just one part of the three building
blocks necessary to complete a Niles IR repeating system:
• IR Main System Unit—Models MSU140,
MSU250, MSU480 and MSU440Z.
• IR Sensors/Keypads—Models WS100, TS100,
MS100, MS200, CS100, MVC100IR and the
Intellipad.
• IR Flashers—Models MF1, MF1VF, MF2,
MF2VF and the IRB1.
An IR sensor expansion hub, Model IRH610,
is available to provide additional sensor inputs
to your system.
INSTALLATION CONSIDERATIONS
Wiring MS200 Sensors
From every IR Sensor location, you must “home-
run” a cable back to the main system unit. “Homerun” means an individual cable is connected
between each IR Sensor and the main system unit.
You should never
daisy-chain (connect in parallel)
two or more IR Sensors to a single input. (Figure 2)
Type of Cable
The MS200 connects to the Niles Infrared Main
Systems Unit or IRH610 sensor expansion hub
with an individual home run of category 5 cable.
When running wires inside walls, most states and
municipalities in the U.S. specify that you must
use a special type of wire. Usually, the requirement is that the wire has a specific “CL” fire rating,

EMI (Electromagnetic Interference)
Identify the source of the interference. The most
common sources of electromagnetic interference are listed in the Installation Considerations
section on page 8. To eliminate EMI try the following methods:
1. Move the sensor or the sensor cable away
from the EMI source
or move the source of
the EMI away from the sensor or the cable.
2. Connect the Sensor’s GND terminal to true
earth ground (if this isn’t feasible use the main
system unit’s GND terminal).
There are many methods for reducing interference. Which solution is best for you depends
on your situation. Contact Niles Technical
Support at 1-800-289-4434 if you require
further assistance.
The conditions which sometimes combine to
create a feedback loop are:
1. Both a sensor and a flasher are located within
the same room.
2. There is some low-level noise or interference
on your system.
You can eliminate optical feedback by replacing
any IRB-1 “flooding flasher” with an MF1 or
MF2 MicroFlasher™ and covering all flashers
with the supplied IR blocking covers.
Identifying the type of interference
The blue “flash-back” LED on the front of the
MS200 is a useful trouble-shooting aid.
If the MS200 does not work, and the LED does
not light at all:
Test the remote control(s) by
operating the A/V equipment directly. Replace
the batteries if needed. Double check the cable
connections on all MS200’s main system unit
and on the IR main system unit. Consult your IR
main system unit’s manual for more detail.
If the MS200 does not work, and the LED “flick-
ers” blue or remains solidly lit:
Cover up the
Sensor with a piece of cardboard (your hand will
actually create electromagnetic interference
under some conditions). Observe the IR test LED.
(MSU140, MSU250, MSU480 MSU440Z,
IntelliControl).
The bi-color blue/green LED on the front of the
MS200 is a useful troubleshooting aid.
The blue LED should light only when a remote
command is being received. If the LED on the
MS200 “flickers”, and the MS200 functions normally, there is no cause for concern, some stray
IR signal are being received by the MS200 but
are not being repeated.
1. Test the remote control(s) by operating the
A/V equipment directly. Replace the batteries
if needed.
2. Double check the cable connections on all
MS200's and on the main system unit. Look
for open, shorted or reversed wires.
3. Test for interference from the following
sources:
• Neon or halogen lights in the room.
• Light dimmers, beginning with those
closest to the MS200.
Observe the MS200’s LED while performing all
the tests. It is possible to have interference from
more than one source.
Eliminating optical feedback
In some installations, two conditions combine
to create an optical feedback loop. Symptoms
can include: poor range, intermittent operation
or no operation.
2. Use a small flathead screwdriver or your thumbnail to raise the locking tabs, exposing the holes
on the removable connector plug of the MSU.
3. Insert each wire into the appropriate hole on
the removable connector plug, and snap the
locking tab down. To help you, the connector
plug is keyed. Insert the smooth side of the
connector plug into the smooth side of
the socket. Don’t force the scalloped side
of the connector plug into the smooth side
of the socket.
4. Double-check all connections. This manual
contains instructions for the MS200 only.
For specific information on the adjustment
of your Niles Infrared system, please refer to
the instruction manual included with your
Niles IR main system unit.
OPERATION
Operation of the MS200 is straightforward.
Simply aim your hand-held remote at the
MS200. Your IR command is instantly repeated
to your A/V equipment. A blue “flash-back” LED
on the MS200 visually confirms the reception of
an IR signal.
TROUBLESHOOTING
This manual contains instructions for the MS200
only. For specific information on the adjustment
and operation of your Niles infrared extender
system, please refer to the instruction manual
included with your Niles IR main system unit
Clean and dry the mounting surface. Peel off the
protective layer on the self-adhesive pad and
firmly affix the MS200 to the mounting surface.
Testing for EMI (Electro Magnetic Interference)
1. Turn on the device. If it is a wall mounted
light dimmer turn the dimmer knob to the
halfway position.
2. Connect the MS200 to a main system unit
and plug in the 12VDC power supply.
3. Place the MS200 in the proposed mounting
location and observe the blue “Flashback” LED.
3. If it flickers or lights constantly. This indicates
a high level of electrical interference. Move
the MS200 housing to a location where the
LED does not light.
Extending the cable
Once the cable is in place, label the cable ends
for future reference. The MS200 is supplied with
10' of pre-stripped IR cable. The IR cable may
be lengthened as needed. The IR cable may be
lengthened by splicing it to a recommended IR
cable (See page 4, Installation Considerations—
Type of Cable). You may splice the MS200
cable to another cable by soldering or crimping
the connections. Make sure that you maintain
proper polarity and correct connections through
the splice.
Connecting to the main system unit
1. Strip 1/4" of insulation from the end of each
wire. Tightly twist the end of each wire until
no frayed ends remain.
