Introduction
An infrared (IR) extender system enables you to control your IR remote controlled A/V equipment from a remote location. This
2 4 5
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 operate your equipment.
Installed at the equipment location, the MSU250 receives the IR commands transmitted from your existing hand-held remotes in that room. The commands are carried via a small category 5 cable to your A/V equipment in another room, and instantly “repeated”.
The MSU250 is compatible with all current Niles infrared systems. It may be used along with the Niles TS100, MS100, MS200, WS100, MVC100IR and CS100 IR sensors or the IntelliPad
The model MSU250 is an IR Main System Unit. It is one of three elements that make up an infrared extender system:
• IR Main System Unit —Models MSU140, MSU250, MSU480 and MSU440Z.
• IR Sensors/Keypads—Models WS100, TS100, MS100, MS200, CS100, MVC100IR and the IntelliPad.
• IR Flashers—Models MF1, MF2, MF1VF, MF2VF and the IRB1.
An IR sensor expansion unit, Model IRH610, is available for IR repeater systems used in more than six rooms.

Installation Considerations
Placement of the MSU250
Place the MSU250 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. Placement possibilities include:
1) Table-top (on the floor or shelf behind the equipment) (Figure 2).
2) Wall-mount (affixed to the back of the equipment cabinet or a nearby wall) (Figure 3).

Wiring
From every IR Sensor location you must “home-run” a category 5 cable back to the MSU250. Home run means that an individual cable is connected between each IR Sensor and the MSU250 (Figure 4).
Figure 4: Home run the sensor cable from the sensor to the MSU250.

IntelliPad Wiring
When you are placing both a 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 MSU250. To prevent data feedback an IN4003 Blocking Diode is inserted on the data (IR) line between the IntelliPad and the sensor. The cathode, or blocking side of the diode, faces the IntelliPad. (Figure 5). Note that status wire is connected to IntelliPad’s sta­tus (+) connector.

Sensor/Keypad Cable
The MSU250 connects to IR sensors and the IntelliPad with category 5 cable, with a maximum cable run of 500'.
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'.

STEP DESCRIPTION
3. Test for shorts and interference.
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 T est LED is on or flickers blue there is a short between DATA and GND or interference is present.
Before you proceed to Step 4 consult the Troubleshooting Section beginning on page 14.
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 T ip” on page 6).
Figure 7
Route the connecting wire to the IR Main System Unit. Connect the 3.5mm plug into the jack labeled “Flasher Output” on the MSU250 (Figure 7).
BE SURE TO OBSERVE PROPER POLARITY WHEN EXTENDING THE FLASHER WIRE.
The wire lead marked with a gray stripe is positive (+); the unmarked lead is negative (-).
“TECH TIP”
Make all final connections
to the MSU before
connecting the power
supply. This will avoid
potential damage
to components.

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, DVD, 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.

12 Volt Trigger Output
The Niles MSU250 provides a 12VDC output that can be trig­gered one of two ways:
1. The presence of status voltage on the 12VDC status input jack.
2. Discrete infrared on and off commands. The discrete on and off commands are available for download
at: www.nilesaudio.com/techsupport. This output can be used to trigger any device that requires 12VDC to be activated. Example include:
• Dropping a motorized screen.
• Activating a television lift.
• Turning on a voltage controlled switching device (e.g.: Niles AC-3 voltage controlled switched outlet).
Installation
Simply plug a cable with a 3.5mm plug (tip=positive, sleeve=ground) into the jack labeled “12VDC/200mA OUT­PUT”. Connect the other end of the cable to the device that will be triggered or activated (Figure 8).

Power Status — Introduction
To properly wire an IntelliPad to the MSU250, refer to Figure 5. By providing 3-30 volt AC/DC to the status input jack of your
MSU250 you can send a status signal to sensors or an IntelliPad without running any additional wiring. Built into the MSU250 is a Niles status signal generator. When the MSU250 sees 3-30 volt AC/DC at the status jack it broadcasts a status signal over your existing IR sensor wires. Any sensor or IntelliPad connect­ed to one of your sensor wires will display the power status of your system.
Power Status — Installation Considerations
Proper Power Supply
If status is being supplied from a switched outlet you must con­nect a Niles 12VDC wall adapter (Niles FG00665) into the switched AC power outlet of the preamp/receiver in your system. Any 12VDC power supply with a minimum of 100mA current capacity can be substituted.

NFRARED MAIN SYSTEM UNIT
Extending the Cable
If you must extend the cable from the wall adapter to the MSU250’s status input jack be sure to maintain correct polari­ty. The tip of the plug should be positive (+) and the sleeve negative (-). Any 16 gauge 2-conductor cable can be used to extend the power status cable up to 200'.
Checking the Power Supply
It is possible to check the status power supply itself and any connections that were made to extend the cable by inserting the status plug into the Power jack on the MSU250. If the Power LED lights the status power supply and connections are ok. If the Power LED does not light check all connections and replace the power supply if necessary. For more details on incorporating the IntelliPad please refer to the IntelliPad’s users manual.

Troubleshooting Guidelines
There are three basic problems which prevent proper opera­tion. In the order of probability the problems are:
1. 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.
Systematically troubleshoot the wiring by:
1. Testing your power supply connections.
2. Testing your Sensor connections.
3. Testing your Flasher connections.
4. Testing your cable for shorts and opens.
16
Page 18
I
NFRARED MAIN SYSTEM UNIT
2. Optical or Electromagnetic Interference
Direct 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.
Solution: To eliminate EMI try the following methods:
1. Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable.
2. Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the main system unit’s GND terminal).
17
Page 19
I
NFRARED MAIN SYSTEM UNIT
3. 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.
Solution: You can eliminate optical feedback by replacing any IRB1 “flooding flasher” with MF1 or MF2 MicroFlashers and covering all flashers with the supplied IR blocking covers.
There are many methods for reducing interference. Which solution is best for you depends on your situation. If you require further assistance contact Niles Technical Support at 1-800-289-4434.

Using the MSU250 with the IntelliControl Home Theater automation system
When connecting an MSU flasher output to an IntelliControl “Home Theater” port, a 150-Ohm resistor must be placed between the data and the ground line of the IntelliControl IR sensor input (see figure above). No resistor is needed if the MSU is being connected to the ”2nd Zone” port of the IntelliControl.
