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 your equipment.

IR System Components: The MSU480 IR Main System Unit is one of three elements that make up an infrared extender system:

• MSU480 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.
• IR Sensors/Keypad (sold separately):
  • IR 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-conductor shielded 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 Main System 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 IR sensors.

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.
