Infrared Extender

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 cabi-

net doors, in the rear of a room, or in a different room) and still con-

veniently control your equipment.

The model IRP2+ is an IR Main System Unit. It is one of three elements

that make up an infrared extender system:

1. IR Sensors receive IR commands from hand-held remote controls

and relay the commands to the Main System Unit via a 2-conductor

shielded cable. Generally, sensors are placed so that you can easily

and naturally point your remote control directly at them. Niles offers

an array of easily concealable sensors: wall-mount, ceiling-mount, sur-

face-mount and table-top. IR sensors are the “eyes” of the system.

2. The IR Main System Unit provides a connection hub for the IR

sensors and the IR flashers and is generally located near the A/V com-

ponents. The Main System Unit’s level controls and LED indicators

enable you to calibrate and troubleshoot an IR extender system. The

Main System Unit is the “heart” of an IR extender system.

3. Infrared Flashers transmit the infrared signals from the IR Main

System Unit to your A/V components. Niles manufactures both flood-

ing flashers (model IRC-1) and miniature “pin-point” flashers (model

IRC-2). Flashers are the “voice” of an IR extender system.

Figure 1 In a typical system, the IRP2+ provides for the connection of up to two remote room sensors

(or keypads) and will control a maximum of eight audio/video components via its flasher connections

(four IRC-1 flashers or eight IRC-2 flashers).

Features and Benefits

The IRP2+ 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 (the only exceptions are those

brands using carrier frequencies higher than 64kHz).

●ExclusiveNilesshort-circuitprotectionprovidesforeasyinstallation.

●Accommodates two IR sensors or keypads.

●Provides two low-distortion, high-current Mosfet IR Flasher outputs;

one at full power, one with variable power.

●Red "Power" L.E.D. enables you to test for proper power supply

operation and shorts between + (positive) and GND (ground) on

your sensor connections.

●Green "IR" Test L.E.D. enables you to test for proper operation,

interference, and for shorts between + and DATA on your sensor

connections.

●Built in “Status” generator broadcasts the amplifier “on/off” power

status over existing IR wiring to provide power status display when

used with other Niles products like the IntelliPad that feature status

display LED’s.

●Screw connectors simplify installation.

●Printed circuit board design assures high reliability.

●Two year parts and labor warranty.

●Proudly made in the USA.

IRP2+ Parts Guide

Power Supply

is a UL listed and

approved 12vDC

wall adapter.

Remote Sensor Connections

enable you to connect up to

two remotely located IR sen-

sors or keypads to the IRP2+.

IR Data

Output

allows the link-

ing of multiple

IRP units for

systems requir-

ing large num-

bers of flashers.

Green IR Test LED

enables you to test

for proper operation,

interference, and for

shorts between + and

DATA on your sensor

connections.

Flasher Connections

provide for a maximum of eight flashers

(four IRC-1 flashers or eight IRC-2 flashers).

When more than one flasher is connected

to a single output, it is connected in series.

Status Socket

allows 12vDC wall adapter to

provide amplifier on/off signal

to “status” generator circuitry.

See Power status page 22.

Red Power

Test LED

enables you to

test for proper

power supply

operation and

shorts between

+ and GND on

your sensor con-

nections.

Flasher Level

Control

enables you to re-

duce flasher level to

match your A/V com-

ponent’s sensitivity.

Power Socket

provides fast and

convenient con-

nection of the

power supply.

Installation Considerations

Placement of the IRP2+

Place the IRP2+ conveniently close to the equipment it will be con-

trolling. Generally, the unit is placed in a concealed location because

its controls and indicators are only used during installation. Placement

possibilities include:

1) Table-top (on the floor or 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

IRP2+ on top of or

directly behind a

television set.

Some television

sets produce

intense electro-

magnetic interfer-

ence which may

disable your IR

extender system.

3) Mount the IRP2+ to the wall or cabinet

back. Allow the adhesive to set as long

as possible before connecting cables.

Wiring

From every IR Sensor location you must “home-run” a cable back to

the IRP2+. Home run means that an individual cable is connected

between each IR Sensor and the IRP2+. 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.

Figure 4: Home run the sensor cable from each sensor to the IRP2+.

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.

Keypad Wiring

When you are placing both a keypad 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

either the sensor or the keypad back to the IRP2+. See Figure 5.

Sensor/Keypad Cable

The IRP2+ connects to IR sensors and keypads with 2-conductor shield-

ed cable. Recommended cables are “data grade” cables made of two

22 gauge (or larger) conductors surrounded by a foil shield and a bare

drain (ground) wire. Data grade cable provides the capability for runs

of up to 500 feet to each sensor. Examples are West Penn D291,

Belden 8761 or Carol C2516. Any 22 to 16 gauge 2-conductor shield-

ed cable available at a hardware store will accommodate 150 foot runs

to each sensor.

Flasher Cable

Niles infrared flashers come supplied with a 10 foot 2-conductor 22

gauge cable. Should you need to extend it, use a 16 gauge 2-conduc-

tor cable (“zip-cord”). Shielding is not necessary for a flasher. Flasher

wires can be extended up to 200 feet.

CAUTION!

Do not use un-

shielded cable

between any

remote IR sensor

or keypad and the

IRP2+.

sensor cable is

keypad and then

back to the IRP2+.

Installation

Before you begin, make sure that the sensor/keypad cables, the flash-

er cables and the 12vDC power supply cable will all reach the pro-

posed location of the IRP2+. Mark the cables with labels describing

where the cable originates (rather than which terminal on the IRP2+

it should connect).

For proper installation, follow the steps outlined below in the correct

order. If you discover a fault in the course of installation, go on to the

Troubleshooting Guide before continuing with the next installation step.

STEP

1. Connect and test the

power supply. If it tests OK,

unplug the connector from

the power socket and pro-

ceed.

2. Connect the first Sensor/

Keypad cable to either one of

the Sensor inputs.

3. Test for shorts and interfer-

ence.

DESCRIPTION

A) Plug the supplied 12vDC power supply into an unswitched

120V AC outlet .

B) Plug the connector into the socket marked “Power” on the

IRP2+.

C) If the Power LED does not light, test the unswitched 120

VAC outlet with another appliance. If the outlet tests OK, you

have a defective power supply which must be replaced for you

to continue.

A) Strip 1/4” of insulation from the wire ends of the cable.

B) Attach the exposed wire ends to the appropriate connector.

Be careful to prevent a filament of wire from shorting out two

connectors. Red = +12v Bare = GND Black = DATA

A) Reconnect the power supply. If the Power LED lights and

the IR Test LED stays off, unplug the connector from the

power socket and proceed to Step 4. The following LED con-

ditions show a fault:

• If Power LED is Off there is a short between +12v and GND

• If IR Test LED is On or Flickers there is a short between DATA

and GND OrInterference is present.

Before you proceed to Step 4 consult the Troubleshooting
