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 conveniently control
IR System Components: The MSU250 IR Main
System Unit is one of three elements that make
up an infrared extender system:
- MSU250 IR Main
System Unit: This Main System Unit provides a connection hub for
two IR sensors and/or keypads and up to five 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.
- IR Sensors (sold
Sensors are the "eyes" of the system, receiving IR commands from hand-held remote controls
relaying the commands to the Main System Unit via a 2-conductor
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.
IR Flashers re-transmit the infrared signals from the IR Main
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 MSU250 is compatible with
virtually all brands of A/V equipment and remote controls (using carrier frequencies between 18 and 100kHz).
Flasher Hi/Lo Switch: Two of
the five 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 MSU250
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 MSU250, 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 MSU250
features a 3-30-volt AC/DC status jack which 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
