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.

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.

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 ElectroMagnetic 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 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.

STEP

1. Connect and test the power supply. If it tests OK, unplug the connector from the power socket and proceed.

2. Connect the first Sensor/ Keypad cable to either one of the Sensor inputs.

3. Test for shorts and interference.

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 conditions 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 Or Interference is present.

Before you proceed to Step 4 consult the Troubleshooting Section beginning on page 12

BE SURE TO OBSERVE PROPER POLARITY WHEN

CONNECTING OR EXTENDING THE FLASHER WIRE. IRC-1 the wire lead marked with a gray stripe is

negative (-); the unmarked lead is positive (+). IRC-2 the silver colored wire lead is negative (-); the

copper colored wire lead is positive (+).

5. Connect multiple flashers to a single output by connecting in series.

Use crimp caps, wire nuts or solder to connect the negative of one flasher to the positive of the next flasher as shown to create a series circuit.

T esting the IR Extender System

Test your IR Extender system by following the three principal guidelines:

1. All components can be operated. Test all of your remote controls for all of your equipment.

2. Operation is consistent. A good test is to repeatedly step from Pause to Play with your VCR, CD, Laser, or Tape player remote control. Operation should be identical to standing in front of the component with the remote control pointed directly at the sensor window.

3. Maximum Range between the Remote Control and the Niles IR Sensor is similar to the maximum range between the Remote Control and the A/V component’s IR sensor. Typically a remote control with two batteries will have a 15 to 20 foot range and a remote with four batteries will have a 20 to 30 foot range.

T roubleshooting Guidelines

There are four basic problems which prevent proper operation. In the order of probability the problems are:

Bad Connections or Wiring

If the connections or wiring are wrong, loose, shorted or open the system will not operate properly. The symptoms could include: Power LED flickers or is off, IR Test LED is continuously flickering or on without any remote control use, intermittent operation or no operation.

If you have an IR sensor in the same room as a flasher, and you have some low-level noise or interference, an optical feedback loop can occur which will interfere with proper operation. Symptoms can include: poor range, intermittent operation or no operation.

Steps

•

feedback loops.

Start from Step One

In your installation you may be faced with a combination of the four problems or symptoms that are universal to all of the problems. Rather than trying to guess which problem you have, use a process of elimination. The Troubleshooting section is designed to eliminate the most common problems first. If you start from Step 1 and methodically check everything you will find the problem in much less time than the troubleshooter who makes assumptions.

•

Test for Optical Interference

Reconnect the problematic sensor/keypad to the IRP2+. Cover up the Sensor with a piece of cardboard (your hand will actually create electromagnetic interference under some conditions). Observe the IR test LED.

• IR Test LED On or Flickering: Go to 3 7

• IR Test LED Off: Go to 3 6

•

Optical Interference

Identify the source of the interference. The most common sources of optical interference are listed in the order of their probability:

A) Sunlight. Reflections from windows, mirrors, swimming pools, shiny floors or objects.

B) Fluorescent light fixtures. C) Neon signs. D) A malfunctioning IR Remote Control. E) A malfunctioning Infrared Motion Detector

on your Security system. Either re-orient the sensor or move the source

of interference. Niles infrared sensors have built-in filters to attenuate the effect of visible light. If you add additional filtration you will reduce the effectiveness of the system with remote controls as well as the interference.

If you are using the MS-1 or the MS-2 miniature sensors consider exchanging them for IRR-4D, TIR-1 or the CMS-3 ceiling sensor. These three sensors have AGC circuits which serve as automatic filters.

If you choose to attempt to filter an MS-1 or MS-2, try a temporary material (e.g. a single thickness of facial tissue) and test whether filtration will solve the interference and still give acceptable range.

•

Electromagnetic Interference (EMI)

Identify the source of the interference. The most common sources of electromagnetic interference are listed in the order of their probability:

A) Televisions (particularly large direct view sets).

B) Wall-mounted 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 position).

C) Fluorescent lights (the electronic ballast sometimes emits EMI)

D) Large appliances (air-conditioners, pumps, motors, compressors etc.)

E) AC line noise (noise brought into the system

Page 22

via the wall outlet connected to the IRP2+) Identify the EMI source by turning potential sources on and off (or fully up and fully down) and watching for any change in the IR Test LED on your IRP2+. Once you have identified the source of interference:

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) Shield the sensor with a metal J-Box.

3) Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the IRP2+ GND terminal).

4) Place a ferrite ring around the cable creating the interference. Ferrite rings can be purchased from an electronic supply store.

IMPORTANT

For the

IntelliPad’s status

feedback feature to work, the pre-

amp/receiver con-

trolling your sys-

tem should have a

switched AC out-

let, a switched outlet is a 120v

AC outlet that

switches off,

when the preamp/

rec-eiver is off

and switches on

when it is on via

remote control.

Power Status — Introduction

By adding an IntelliPad™ to your IRP2+ Infrared Extender System you will add a remarkable level of convenience to your system. The IntelliPad is the world’s first programmable, wall-mounted keypad system that provides a unique L.E.D. power status display and the convenience of true one-touch remote control of complex audio/video systems.

The IntelliPad’s status feedback feature eliminates the guesswork common with standard IR control systems. The power L.E.D. on the IntelliPad indicates the On/Off condition of the system’s preamp/receiver.

Built-in intelligence tracks the On/Off condition of the preamp/receiver so the IntelliPad knows when it’s appropriate to issue the power command, even when the user doesn’t. The system maintains perfect synchronization between the amplifier and the user.

By combining an optional Niles 12vDC power supply with your IRP2+ you can send a status signal to an IntelliPad without running any additional wiring. Built into the IRP2+ is a Niles Status Signal Generator. When the IRP2+ sees 12vDC at the status jack it broadcasts a Status signal over your existing IR sensor wires. Any IntelliPad connected to one of your sensor wires will display power status.

The IntelliPad

Source Select Keys A single press of one of these keys will:

1. T urn on the Preamp/Receiver if it was off.

2. Change the input of your preamp/receiver to the selected source.

3. Changes the function of the Source Control Keys so that they operate the selected source.

4. Display which source is selected by backlighting the corresponding Sour

ce Label.

5. T urn on the local speakers (un-mute the speaker relay)

Status LED When the preamp/receiver is on, the status LED is lit. The color of the LED displays whether the local speakers are on or muted.

GREEN - Local Speakers and the Preamp/Receiver are on

RED - Local speakers are off, but the system is on.

OFF - System is off.

Source Control Keys A touch to any of the source control keys will operate the selected source only.

Mute Key A touch to this key controls the IntelliPad’s built in speaker mute feature. You can mute the local speakers anytime, by pressing the Mute Key. To turn the local speakers back on (or unmute) you may press either the Mute key or one of the six Source Select keys.

Power Status — Installation Considerations

Proper Power Supply

You must connect a Niles 12vDC wall adapter (Niles FG00665) into the switched AC power outlet of the preamp/receiver in your system. Any 12vDC power supply with a minimum of 100mA current capacity can be substituted.

Extending the Cable

If you must extend the cable from the wall adapter to the IRP2+’s status input jack be sure to maintain correct polarity. The tip of the plug should be positive (+) and the sleeve negative (-). Any 16 gauge 2conductor cable can be used to extend the power status cable up to 200 feet.

Checking the Power Supply

It is possible to check the status power supply itself and any connections that were made to extend the cable by inserting the status plug into the Power jack on the IRP2+. If the Power LED lights the status power supply and connections are OK. If the Power LED does not light check all connections and replace the power supply if necessary. For more details on incorporating the IntelliPad please refer to the IntelliPad’s users manual.
