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.

Features and Benefits

The MSU140 offers a number of improvements over other

IR Extender Main System Units:

• Universal system—compatible with virtually all brands

of A/V equipment and remote controls.

• Accommodates one IR sensor or keypad.

• Provides four flasher outputs via convenient 3.5mm

jacks.

• System feedback LED confirms operation.

• 3-30V AC/DC status input. Provides system status to con-

nected sensors and keypads.

• Expandable—an IRH610 IR expansion hub can be used

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.

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.

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.
