Introduction
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 MSU480 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 MSU480 is compatible with all current Niles infrared systems. It may be used along with the Niles TS100, MS100,
MS200, WS100, MVC100R and CS100 IR sensors or the IntelliPad
®
.
The model MSU480 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, WS100,
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.

Features and Benefits
The MSU480 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 four IR sensors or keypads.
•Provides eight flasher ouputs via convenient 3.5mm jacks.
• System feedback LED confirms operation.
• 3-30V AC/DC status input. Provides system status to connected
sensors and keypads.
• 12VDC Output—This is useful for triggering external
devices and system automation.
• Expandable—an IRH610 IR expansion hub can be used
to provide additional inputs.
•Two selectable HI/LOW output flasher ports.
• Printed circuit board design assures high reliability.
• Low profile and small footprint with integrated mounting
wings that allow for both horizontal and vertical installation.
•ULlisted regulated in-line power supply with universal
voltage capability.
•Two year parts and labor warranty.

In a typical system, the MSU480 provides
for the connection for one remote room sensor(or keypad) and will control multiple
audio/video components via its flasher
connections.

1. 12V DC 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 (MF2, MF2F, MF2D, MF2DF)
low-level flashers.
3. 3-30V AC/DC Status – 3.5mm jack provides system
status to sensors/ keypads via a 12 volt power supply attached to a switched outlet on the system
receiver or a 12 volt trigger output.
4. 12VDC/200mA Output – When 12VDC voltage is
detected at the status jack or a discrete IR command is issued 12VDC/200mA is output.
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/Low switch – Setting these switches to
the appropriate position allows you to connect
either a high output flooding flasher (IRB1) or low
output MicroFlashers (MF2, MF2F, MF2D, MF2DF).
7. Contact Closure Switch – Two position switch that
determines if the contact closure is activated by
either (a) the presence of status or (b) discrete IR
commands.
8. Contact Closure Plug – Three position quick connect plug for connecting either a NO (normally
open) or NC (normally closed) contact closure
device to the MSU480
9. Sensor Input – Four position quick connect plug for
connecting IR sensor and/ or IntelliPad‚ to the
MSU480.
10. Sensor Input Labels – Recessed label slot for instal-
lation of preprinted room identification labels.

IMPORTANT
Do not place the
MSU480 on top of
or directly behind
a television set.
Some television
sets produce intense
electromagnetic
interference which
may disable your
IR extender system.

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 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).
