IR System Overview: 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 convenientlycontrol your equipment.
IR System Components:The MSU480 IR Main System Unit is one of three elementsthat make up an infrared extender system:
IR Main System Unit: This Main System Unit provides a connection hub for
four IR sensors and/or keypads and up to eight
IR flashers and is generally located near the A/V components.The Main System Unit, which is the "heart" of an IR
extender system, has LED indicators to monitor
the IR extender system.
Sensors/Keypad (sold separately):
Sensors: IR Sensors are the "eyes" of the system, receiving IR
commands from hand-held remote controls and
relaying the commands to the Main System Unit via a 2-conductorshielded cable. Generally, sensors are placed so
that you can easily and naturally point your remote control directly at
them. Sensors are available in wall-mount, ceiling-mount, surface-mount
and table-top models.
- Keypad: The IntelliPad
is a wall-mounted, programmable IR keypad system that provides a unique
LED power status display and the convenience of true one-button remote
control of complex audio/video systems.
- IR Flashers
(sold separately):IR Flashers re-transmit the infrared signals from the IR MainSystem Unit to your A/V components. Flashers are the
"voice" of an IR extender system that "speaks" to your components.
Universal Compatibility: With
the necessary accessories, an IR remote control extender system using the MSU480
is compatible with virtually all brands of A/V equipment and remote controls
(using carrier frequencies between 26 and 105 kHz).
Flasher Hi/Lo Switch: Two of
the eight IR flasher outputs have switchable high/low output. When switched to
High, you can connect a high-output flooding flasher, such as an IRB1 (item
190IRB1). When in the Low position, you can connect low-output micro-flashers,
such as MF1, MF1VF, MF2 or MF2VF.
LED Indicators: The MSU480
provides a visible indication of system status via a green LED and confirms
reception of IR data via a blinking blue LED.
Wiring: From every IR sensor,
you must "home-run" a Category 5 ("Cat 5") cable back to the MSU480, connecting
each sensor to the hub with an individual cable. The Cat 5 cable should be
terminated with the supplied quick connect sensor plugs. The IR flashers connect
to the hub via 3.5mm (1/8") mini-plugs.
12 Volt Trigger: The MSU480
features a 3-30-volt AC/DC status jack that provides system status to sensors
and keypads via a 12-volt power supply attached to a switched outlet (found on
many audio receivers) or an optional 12-Volt trigger output. When 12 volts is
detected at the status jack, the 12-volt output jack will output 12 Volts/200mA
DC. This is useful for triggering external devices and system automation.
Expandability: The IR System
can be easily expanded through the use of an IRH610 IR Sensor Expansion Hub
(available from the manufacturer). The expansion hub allows you to add up to 6
Contact Closure Plug: The
MSU480 has a three position quick connect plug for connecting either a NO
(normally open) or NC (normally closed) contact closure device. There is a two
position switch that determines if the contact closure is activated by either
the presence of status or discrete IR commands.
