INTRODUCTION
The MSU-250 an infrared (IR) extender system enables you to control your IR remote controlled
A/V equipment from a remote location. This 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 CAT-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 TS110, MS110, MS210, WS110, and CS110 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 WS110, TS110, MS110, MS210, CS110, 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.

FEATURES AND BENEFITS
The MSU250 offers 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 two IR sensors or keypads
• Provides five flasher outputs via convenient 3.5mm jacks
• System feedback LED confirms operation
• 12VDC Output—This is useful for triggering external devices and system automa
-
tion
• 3-30V AC/DC status input. Provides system status to connected sensors and key
-
pads
• Expandable—an IRH610 IR expansion hub can be used to provide additional inputs.
• 2x variable flasher out (4 + 5)
• Printed circuit board design assures high reliability
• Low profile and small footprint with integrated mounting wings that allow for
both horizontal and vertical installation
• UL listed regulated in-line power supply with universal voltage capability.
• Two year parts and labor warranty

will control multiple audio/video
components via its flasher
connections.

1. 12VDC Jack – Provides 12 volt DC power to MSU via a regulated power supply
2. IR Flasher Outputs – 3.5mm jacks provide output for either single or dual (MF1, MF1VF,
MF2, MF2VF) low-level flashers
3. 3-30V AC/DC Status – 3.5mm jack provides system status to sensors/ keypads via a
12V power supply attached to a switched outlet on the system receiver or a 12V trigger
output
4. 12V Output – When 12 volts is detected at the status jack (#3) the 12V output jack
will output 12V/200mA DC. This is useful for triggering external devices and system
automation

FEATURES AND BENEFITS
5. Status/IR Confirmation LED – This LED performs two functions: (1) it provides a
visible indication of system status via a green LED and (2) confirms the reception of IR
data via a blinking blue LED
6. Flasher Hi/Lo switch – Setting these switches to the appropriate position allows you to
connect either a high output flooding flasher (IRB1) or low output microflashers (MF1,
MF1VF, MF2, MF2VF)
7. Sensor Input – Removable quick connect sensor plug for connection of IR sensors to the
system
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)

INSTALLATION CONSIDERATIONS (CONTINUED)
WIRING
From every IR Sensor location you must “home-run” a CAT-5 cable back to the MSU250.
Home run means that an individual cable is connected between each IR Sensor and the MSU250
(Figure 4).
