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 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, surface-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 components. 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 flooding flashers (model IRC-1) and miniature “pin-point” flashers (model IRC-2). Flashers are the “voice” of an IR extender system.

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).

● ExclusiveNiles short-circuit protectionprovides foreasy installation.

● 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.

Flasher Level Control

enables you to reduce flasher level to match your A/V component’s sensitivity.

Status Socket

allows 12vDC wall adapter to provide amplifier on/off signal to “status” generator circuitry. See Power status page 22.

IR Data Output

allows the linking of multiple IRP units for systems requiring large numbers of flashers.

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.

Installation Considerations

NN II TT

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.

Placement of the IRP2+

Place the IRP2+ conveniently close to the equipment it will be controlling. 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 .

Figure 2: Table-Top Placement

1) Clean the bottom of the IRP2+ and the mounting surface with the enclosed alcohol pad.

2) Affix the enclosed self-adhesive rubber feet to the base of the IRP2+.

Figure 3: Wall-Mount Placement

1) Clean both mounting surfaces with the enclosed alcohol pad.

2) Affix the two enclosed strips of self adhesive Velcro® to the back of the IRP2+.

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.

IMPORTANT – AVOIDING INTERFERENCE

Avoid locating any of the cables, Sensors, Keypads or the Main System Unit near any potential sources of ElectroMagnetic Interference (EMI), such as light dimmers, speed controls for ceiling fans, electrical ballasts, television sets, large motors, heaters or air conditioners.

number . The lower

the AWG number,

the larger the wire,

i.e., 20 AWG wire is

physically larger than

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 shielded 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 shielded 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-conductor cable (“zip-cord”). Shielding is not necessary for a flasher. Flasher wires can be extended up to 200 feet.

Installation

Before you begin, make sure that the sensor/keypad cables, the flasher cables and the 12vDC power supply cable will all reach the proposed 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.
