DS00330ACN/MSU480 12/19/03 I 9:05 AM M N F R A R E D Page 5 S A I N Y S T E M U N I T Installation Considerations IMPORTANT Do not place the MSU480 on top of or directly behind a television set. Some television sets produce intense electromagnetic interference which may disable your IR extender system. Placement of the MSU480 Place the MSU480 conveniently close to the equipment it will be controlling.
DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 6 A I N S Y S T E M Wiring From every IR Sensor location you must “home-run” a category 5 cable back to the MSU480. Home run means that an individual cable is connected between each IR Sensor and the MSU480 (Figure 4). U N I T “TECH TIP” Remotely Located IR Sensors Figure 4: Home run the sensor cable from the sensor to the MSU480. SENSORS IN S T A T U S Wire size is expressed by it’s AWG (American Wire Gauge) number.
DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 7 A I N S Y S T E M U N I T Intellipad Wiring When you are placing both an IntelliPad 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 back to the MSU480. To prevent data feedback an IN4003 Blocking Diode is inserted on the data line between the Intellipad and the sensor.

DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 10 A I N S Y S T E M U N I T STEP DESCRIPTION 1. Connect and test the power supply. If it tests OK, unplug the connector from the power socket and proceed. A) Plug the supplied 12VDC power supply into an unswitched 100-240V AC outlet . B) Plug the connector into the socket marked “Power” on the MSU480. C) If the Power LED does not light, test the unswitched 100-240V AC outlet with another appliance.
DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 11 A I N S Y S T E M U N I T STEP DESCRIPTION 4. Plug the flashers into 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 wire to the IR Main System Unit. Connect the 3.5mm plug into the jack labeled “Flasher Output” on the MSU480. WARNING! Before connecting flashers to ports 7 & 8 set the HI/LOW switches to the appropriate position.
DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 12 A I N S Y S T E M U N I T Testing 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, DVD, or Tape player remote control.

Set the contact closure dip switch, located above the screwless connector, to the appropriate position for triggering (Figure 8).
DS00330ACN/MSU480 12/19/03 I 9:05 AM N F R A R E D M Page 15 A I N S Y S T E M U N I T Power Status — Installation Considerations Proper Power Supply You may connect a Niles 12VDC wall adapter (Niles FG00665) into the switched AC power outlet of the preamp/receiver in your system. Any 3-30V AC/DC power supply with a minimum of 20mA current capacity can be substituted.
