Introduction

IRP6+

INFRARED EXTENDER SYSTEM— IR MAIN SYSTEM UNIT

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.

Th e model IRP6+ is an IR Main System Unit. It i s on e of th re e 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: wallmount, ceiling-mount, surfacemount and table-top. IR sensors are the “eyes” of the system.

2. The IR Main System Unit pro- vides a connection hub for the IR sensors and the IR flashers and is generally located near the A/V components. The IR Main System Unit’s level controls and LED indicators enable you to calibrate and troubleshoot an IR extender system. The

Supply

Six remotely located IR Sensors are connected to an IRP6+. One IR Flasher, connected to the IRP6+, is transmitting an IR command to the Receiver’s IR sensor. The IRP6+ enables you to connect up to eight Niles IRC-1 Flooding Flashers and up to sixteen Niles IRC-2 MicroFlashers. The IRP-6+ is powered by plugging into an unswitched AC outlet.

flashers (model IRC-1) and miniature “pin-point” flashers (model IRC-2).

Features and Benefits

The IRP6+ 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).

• Exclusive Nilesshort-circuit protectionprovides foreasy installation.

• Accommodates six IR sensors or keypads.

• Provides four low-distortion, highcurrent, variable-power Mosfet IR

Flasher outputs

• 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.

Placement of the IRP6+

Place the IRP6+ 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.

IMPORTANT: Do not place the IRP6+ 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 cable back to the IRP6+. Home run means that an individual cable is connected between each IR Sensor and the IRP6+. See Figure 3.

IMPORTANT: 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.

Remote Sensor Connections

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 IRP6+. See Figure 4.

Sensor/Keypad Cable

The IRP6+ 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.

CAUTION: Do Not use un-shielded cable between any remote IR sensor or keypad and the IRP6+.

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 continued

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.

4. Connect the flashers to the flasher outputs. If you need to extend the wire, use a 2-conductor 16 gauge or larger (See Tech Tip on page 6).

DESCRIPTION

A) Plug the supplied12v DC power supply into an unswitched 120v AC outlet. B) Plug the connector into the socket marked “Power” on the IRP6+. C) If the Power LED does not light, test the unswitched 120v AC 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

Route the connecting 2-conductor wire to the IR Main System Unit. Connect the ends of the wire to the corresponding positive and negative terminals labeled “Flasher” on the IRP6+.

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 (+).

Figure 3

Installation

Before you begin, make sure that the sensor/keypad cables, the flasher cables and the 12v DC power supply cable will all reach the proposed location of the IRP6+. Mark the cables with labels describing where the cable originates (rather than which terminal on the IRP6+ it should connect to).

For proper installation, follow the steps outlined 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.

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.

IRC-1 Flooding Flasher

Allows a maximum of TWO in series.

IRC-2 MicroFlasher

Allows a maximum of FOUR in series.

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

Disc, 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.
