I NFRARED M AIN S YS TEM U NIT 2 Featur es and Benefits The MSU480 of fers 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. • Accommodates four IR sensors or keypads.

Installation Considerations Placement of the MSU480 Place the MSU480 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 dur- ing installation.
W iring Fr om 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). 6 I NFRARED M AIN S YS TEM U NIT “TECH TIP” W ire size is expressed by it’ s AWG (American Wi re Gauge) number .
Intellipad W iring When you ar e 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.
System Expansion System expansion is easily achieved (Figur e 6) through the use of an IRH610 Infrared Sensor Expansion Hub. Please see your authorized Niles dealer or refer to the IRH610 manual for details.

I NFRARED M AIN S YS TEM U NIT 10 STEP 1. Connect and test the power supply . If it tests OK, unplug the connector from the power socket and proceed. 2. Connect the Sensor/ Keypad cable the Sensor input. 3. T est for shorts and interference. DESCRIPTION A) Plug the supplied 12VDC power supply into an unswitched 100-240V AC outlet .
I NFRARED M AIN S YS TEM U NIT STEP 4. Plug the flashers into the flasher outputs. If you need to extend the wire, use a 2-conductor 16 gauge or larger (See “T ech Tip” on Page 6). DESCRIPTION Route the connecting wire to the IR Main System Unit. Connect the 3.
12 I NFRARED M AIN S YS TEM U NIT T esting the IR Extender System T est your IR Extender system by following the three principal guidelines: 1. All components can be operated. T est all of your remote controls for all of your equipment. 2. Operation is consistent.
13 I NFRARED M AIN S YS TEM U NIT 12 V olt T rigger Output The Niles MSU480 pr ovides a 12VDC output that can be trig- gered one of two ways: 1. The presence of status voltage on the 3-30V AC/DC status input jack or 2. Discrete infrared on and off commands.
14 I NFRARED M AIN S YS TEM U NIT Contact Closur e The Niles MSU480 pr ovides a contact closure that can be triggered one of two ways: 1. The presence of status voltage on the 3-30V AC/DC status input jack or 2.
15 I NFRARED M AIN S YS TEM U NIT Power Status — Installation Considerations Proper Power Supply Y ou 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.
16 I NFRARED M AIN S YS TEM U NIT 2. Optical or Electromagnetic Interference Dir ect 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.
1 7 I NFRARED M AIN S YS TEM U NIT Specifications IR System Compatible with virtually all brands of remotes using carrier frequencies between 26 and 1 05kHz. W iring Requirements Individual home-runs of category 5 cable from each sensor/keypad. Unit Dimensions 7-1/16” wide x 1-1/4” high x 3” deep Power Requir ements 12 VDC 1.
