MSU140
Infrared Main
System Unit
Introduction
An infrared (IR) extender system enables you to control
your IR remote controlled A/V equipment from a remote
location. This enables you to place your A/V components
out of sight (behind cabinet doors, in the rear of a room, or
in a different room) and still conveniently operate your
equipment.
Installed at the equipment location, the MSU140 receives
the IR commands transmitted from your existing hand-
held remotes in that room. The commands are carried via a
small category 5 cable to your A/V equipment in another
room, and instantly “repeated”.
The MSU140 is compatible with all current Niles infrared
systems. It may be used along with the Niles TS100, MS100,
MS200, WS100, MVC100IR and CS100 IR sensors or the
IntelliPad®.
The model MSU140 is an IR Main System Unit. It is one of
three elements that make up an infrared extender system:
• IR Main System Unit—Models MSU140, MSU250,
MSU480 and MSU440Z.
• IR Sensors/Keypads—Models WS100, TS100, MS100,
MS200, CS100, IntelliPad, MVC100IR.
• IR Flashers—Models MF1, MF2, MF1VF, MF2VF.
An IR sensor expansion hub, Model IRH610, is available to
provide additional sensor inputs to your system.

to provide additional inputs.
• Printed circuit board design assures high reliability.
• Low profile and small footprint with integrated mount-
ing wings that allow for both horizontal and vertical
installation.
• UL listed regulated in-line power supply with universal
voltage capability.

In a typical system, the MSU140 provides
for the connection for one remote room
sensor (or keypad) and will control multiple
audio/video components via its flasher
connections.

MSU140 Parts Guide
1. 12V DC Jack – Provides 12 volt DC power to
MSU via a regulated power supply.
2. IR Flasher Outputs – 3.5mm jacks provide out-
put for either single or dual (MF1, MF2,
MF1VF, MF2VF) low-level flashers.
3. 3-30V AC/DC Status – 3.5mm jack provides
system status to sensors/ keypads via a 12 volt
power supply attached to a switched outlet on
the system receiver or a 12V trigger output.
4. Status/ IR Confirmation LED – This LED
performs two functions: (1) it provides a
visible indication of system status via a green
LED and (2) confirms the reception of IR data
via a blinking blue LED.
5. Sensor Input – Removable quick connect
sensor plug for connection of IR sensors
(WS100, TS100, MS100, MS200, CS100
MVC100IR and the IntelliPad) to the system.

Installation Considerations
Placement of the MSU140
Place the MSU140 conveniently close to the equipment it
will be controlling. Generally, the unit is placed in a con-
cealed location because its controls and indicators are only
used during installation. Placement possibilities include:
1) Table-top (on the shelf behind the equipment)
See Figure 2.
2) Wall-mount (affixed to the back of the equipment
cabinet or a nearby wall). See Figure 3.

IMPORTANT
Do not place the
MSU140 on top
of or directly
behind a television
set. Some
television sets
produce intense
electromagnetic
interference which
may disable
your IR extender
system.

Wiring
From every IR Sensor location you must “home-run” a
category 5 cable back to the MSU140. Home run means
that an individual cable is connected between each IR
Sensor and the MSU140. See Figure 4.

“TECH TIP”
Wire size is
expressed by it’s
AWG (American
Wire Gauge)
number. The lower
the AWG number,
the larger the wire,
i.e., 20 AWG wire is
physically larger
than 22 AWG.
IMPORTANT – AVOIDING INTERFERENCE
Avoid locating any of the cables, sensors, keypads or the
Main System Unit near any potential sources of Electro-
Magnetic Interference (EMI), such as light dimmers, speed
controls for ceiling fans, electrical ballasts, television sets,
large motors, heaters or air conditioners.

sensor cable from the
sensor to the MSU140.

Intellipad Wiring
When you are placing both a Intellipad and a sensor (or
two keypads) in one room you may “daisy-chain” using a
single cable. A cable is run between the keypad and the
sensor and a single cable is run from the sensor back to the
MSU140. To prevent data feedback an IN4003 Blocking
Diode is inserted on the data (IR) line between the
Intellipad and the sensor. The cathode, or blocking side of
the diode, faces the Intellipad. See Figure 5. Note that the
status wire is connected to Intellipad’s status (+) connector.

Sensor/Keypad Cable
The MSU140 connects to IR sensors and the Intellipad with
category 5 cable, with a maximum cable run of 500'.
Flasher Cable
Niles infrared flashers come supplied with a 10 foot 2-con-
ductor 22 gauge cable. Should you need to extend it, use a
16 gauge 2-conductor cable (“zip-cord”). Shielding is not
necessary for a flasher. Flasher wires can be extended up to
200 feet.

STEP DESCRIPTION
1. Connect and test the
power supply. If it tests
OK, unplug the connector
from the power socket
and proceed.
A) Plug the supplied 12vDC power supply into an unswitched
120V AC outlet, 50-60 HZ .
B) Plug the connector into the socket marked “Power” on the
MSU140.
C) If the Power LED does not light, test the unswitched 120
VAC outlet, 50-60 HZ with another appliance. If the outlet
tests OK, you have a defective power supply which must be
replaced for you to continue.
2. Connect the Sensor/
Keypad cable the Sensor
input.
A) Strip 1/4" of insulation from the end of each wire. Tightly
twist the end of each wire until no frayed ends remain.
B) Use a small flathead screwdriver or your thumbnail to raise the
locking tabs, exposing the holes on the removable connectors.
C) Insert each wire into the appropriate hole on the removable
connector plug (Figure 6), 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 sock-
et. Don’t force the scalloped side of the connector plug into
the smooth side of the socket.
