Some television sets produce intense electromagnetic interference which may disable your IR extender system. Placement of the MSU140 Place the MSU140 conveniently close to the equipment it will be controlling.
DS00329BCN-MSU140-1.qxp I N F R A 8/17/05 R E D 11:26 AM M A I N Page 6 S Y S T E M Wiring From every IR Sensor location you must “home-run” a category 5 cable back to the MSU140. Home run means that an individual cable is connected between each IR Sensor and the MSU140. See Figure 4. U N I T “TECH TIP” Remotely Located IR Sensor Figure 4: Home run the sensor cable from the sensor to the MSU140.

A cable is run between the keypad and the sensor and a single cable is run from the sensor back to the MSU140. To prevent data feedback an IN4003 Blocking Diode is inserted on the data (IR) line between the Intellipad and the sensor.

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.

If it tests OK, unplug the connector from the power socket and proceed. A) Plug the supplied 12vDC power supply into an unswitched 120V AC outlet, 50-60 HZ . B) Plug the connector into the socket marked “Power” on the MSU140. C) If the Power LED does not light, test the unswitched 120 VAC outlet, 50-60 HZ with another appliance.

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.

By providing 3-30V AC/DC to the status input jack of your MSU140 you can send a status signal to sensors or an IntelliPad without running any additional wiring. Built into the MSU140 is a Niles status signal generator.

Any 12vDC power supply with a minimum of 100mA current capacity can be substituted.

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.

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). 3.
