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

an IR extender system.

3. Infrared Flashers transmit the
infrared signals from the IR Main
System Unit to your A/V compo­nents. Niles manufactures flooding

DC Power

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.

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.
