Installation
If you are installing the MS120 into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood or metal studs; electrical, telephone or other types of wiring; plumbing; AC or heating conduits; old wall safes; etc.
1.Determine a mounting location for the MS120.
Select a location where you will have access to the rear of the MS120 after it is installed. This will allow you to securely tighten the MS120 to the mounting surface using the supplied hardware.
2.Drill a 1/2” hole where the MS120 will be mounted.
3.Run the MS120’s IR cable. Label the cable for future reference. The MS120 is supplied with
10’ of pre-stripped IR cable. The IR cable may be shortened or lengthened as needed. If you want to make the MS120’s cable shorter, use a pair of wire cutters to cut the cable to the desired length. The IR cable may be lengthened by splicing it to a recommended IR cable (See
Installation Considerations—Type of Cable). You may splice the MS120 cable to another cable by soldering or crimping the connections.
4.Connect the MS120 cable to the main system unit. Strip 1/4” of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends. Insert the end of
9
each wire into the appropriate hole on the main system units’ screwless connector (Figure 2), and snap the locking tab down. To help you, the connector plug is keyed. Insert the smooth side of the connector plug into the smooth side of the socket. Don’t force the scalloped side of the connector plug into the smooth side of the socket.
6.Secure the MS120 by tightening the hex nut.
DO NOT OVER-TIGHTEN.
Tools Required
•1/8” Standard Slotted Screwdriver
•Adjustable wrench or pliers
•Wire Stripper
NOTE: Do not install the MS120 next to a light dimmer
OPERATION
Operation of the MS120 is straightforward. Simply aim your hand-held remote at the MS120. Your IR command is instantly repeated to your A/V equipment.

TROUBLESHOOTING
This manual contains instructions for the MS120 only. For specific information on the adjustment and operation of your Niles infrared extender system, please refer to the instruction manual included with your Niles IR main system unit (MSU140, MSU250, MSU480 MSU440Z).
1.Test the remote control(s) by operating the
A/V equipment directly. Replace the batteries if needed.
2.Double check the cable connections on the
MS120 and on the main system unit. Look for open, shorted or reversed wires.
3.Test for interference from the following sources:
•Neon, Compact Florescent Lighting (CFL), or halogen lights in the room
•Light dimmers, beginning with those closest to the MS120
Observe the main system unit IR confirmation LED while performing all the tests. It is possible to have interference from more than one source.
Eliminating Optical Feedback
In some installations, two conditions combine to create an optical feedback loop. Symptoms can include: poor range, intermittent operation or no operation.
11
The conditions which sometimes combine to create a feedback loop are:
1.Both a sensor and a flasher are located within the same room.
2.There is some low-level noise or interference on your system.
You can eliminate optical feedback by replacing any IRB1 “flooding flasher” with an MF1 or MF2 MicroFlasher® and covering all flashers with the supplied IR blocking covers.
EMI (Electromagnetic Interference)
Identify the source of the interference. The most common sources of electromagnetic interference are listed in the Installation Considerations section. 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).
There are many methods for reducing interference. Which solution is best for you depends on your situation. If you require further assistance call Niles Technical Support at 305-238-4373 or 1-800-289-4434
(M-F 8:00 AM - 7:00PM ET).
