B LENDING H IGH F IDELITY AND A RCHITECTURE ® IRP6+ INFRARED EXTENDER SYSTEM-- IR 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 cabinet doors, in the rear of a room, or in a different room) and still conveniently control your equipment. MODEL IRP6+ VID The model IRP6+ 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 IR DATA OUT FLASHERS 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 provides 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 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 flooding flashers (model IRC-1) and miniature "pin-point" flashers (model IRC-2). POWER STATUS +- +- +- +- G N D D A T A +12V DC Remotely Located IR Sensors Figure 1 IR Remote Controllable Stereo Receiver DC Power Supply IRP6+ 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. 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 Niles short-circuit protection provides for easy 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. ® Niles Audio Corporation Installation Considerations 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. Room 1 Remotely Located IR Sensors Installation continued STEP DESCRIPTION A) Plug the supplied 12v 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 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). 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 (+). 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. Remote Sensor Connections Figure 2 Flasher Level Controls Green IR Test LED IR Data Output Flasher Connections Red Power Test LED Power Socket Status Socket 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. 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 IR DATA + 12 V 1 G N D 2 D A T A 3 + 12 V G N D D A T A of up to 500 feet to each sensor. Examples are West Penn D291, Belden 8761 or Carol C 2516. 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. Sensor + 12 V G N D D A T A 3.

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.

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.

A good test is to repeatedly step from Pause to Play with your VCR, CD, Laser MS-1 Sensor Troubleshooting Guidelines There are four basic problems which prevent proper operation of your IRP6+. In the order of probability, the problems are as follows: 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. Steps (3) and (4) test your power supply connections. Steps (13) thru (14), (23) thru (25) test your Sensor connections. Steps (15) thru (18) test your Flasher connections. Steps (26) and (27) tests your cable for shorts and opens. Flasher Level is Too High Many audio/video component's sensors are overloaded by receiving too strong of an IR command from the flasher. Symptoms can include: popping and clicking sounds from the speakers when a button is pressed on the remote control, poor IR receiving range, intermittent operation or no operation. Step (15) provides detailed instructions on setting the proper flasher level. Optical or Electromagnetic Interference Sunlight, reflections, neon signs and other sources of infrared light or television sets, light dimming controls and other sources of electromagnetic fields can induce noise and interference into your IR extender system. Symptoms can include: flashback LED's continuously flickering or on without any remote control use, poor range, intermittent operation or no operation. Steps (32) through (38) troubleshoot interference problems. Optical Feedback Loop 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 (19)through (22) provide instructions for eliminating optical 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. Troubleshooting Guide continued 10) Replace the IRP6+ If you have another IRP6+, replace the one in the system and retest, if not go to Step 11. 11) Replace the Sensor or Keypad If you have another Sensor or Keypad, exchange it and retest the system, otherwise return the IRP6+ and the sensor/keypad(s) to your local Niles dealer for testing. 12) System suddenly seems to be OK again. The connections were poor and by touching and inspecting them you have changed their condition. Jiggle and tug on the wires and recheck the connections. If they all seem secure, retest the entire system per the Troubleshooting Guidelines. 13) IR LED without any IR input. Observe the green IR Test LED on the IRP6+ with the power supply plugged in and all sensors and flashers connected. · IR Test LED is On or is Flickering: Go to Step 32 · IR Test LED is Off: Go to Step 14 B) If you DO h ...
