he RCA-SM2 kit from Niles gives you easy control over your audio/video system, even if your gear is placed out of sight in a cabinet or closet. It includes everything you need to set up a complete IR (infrared) repeater system and control up to three A/V components:

• MS220 IR sensor - Mount this small sensor in a convenient spot, like next to your TV. It sends the IR commands from your remote control to the IR hub.
• MSU140 IR hub - Accepts incoming IR signals and passes them on to your A/V components.
• three MF1 flashers - Infrared light-emitting devices that carry IR commands from the MSU140 to your A/V gear.
• 50 feet of CAT-5 cable to connect the IR sensor to the IR hub.

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: This infrared extender system includes the following items:

• IR Main System Unit: The MSU140 IR Main System Unit provides a connection hub for the IR sensor or keypads and up to four IR flashers, and it is generally located near the A/V components. The Main System Unit is the heart of an IR extender system.
• IR Sensors: IR Sensors, like the included MS220 surface mount model, 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 CAT-5 or a 4-conductor shielded cable. Generally, sensors are placed so that you can easily and naturally point your remote control directly at them. Sensors are also available in wall-mount, ceiling-mount and tabletop models.
• IR Flashers: These IR MicroFlashers 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.

MSU140 Main System Unit Features

Universal Compatibility: With the necessary accessories, an IR remote control extender system using the MSU140 is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies between 26 kHz and 105 kHz.

Wiring: If the distance from the IR sensor to the MSU140 is longer than the attached 10' cable, it can be extended with the included 50' Category 5 (Cat 5) 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.

Status Input: The MSU140 features a 3-30-volt AC/DC status input jack which provides system status to sensors and keypads when connected to a switched AC or DC output on an audio receiver or preamp. An optional 12-Volt adapter may be necessary.

MS220 IR Sensor Features

Universal Compatibility: When used in a complete system, this IR sensor is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies of between 25kHz and 90kHz. The MS220 is also compatible with the recently introduced Philips RCMM codes.

Universal Noise Suppression: The sensor has a patent-pending Universal Noise Suppression design that effectively eliminates IR interference from plasma and LCD TVs, CFL (fluorescent) lighting, and direct sunlight. This two-stage technology combines an optical noise filter with a smart electronic circuit to provide consistent, reliable control.

IR Receiving Range: You get 20' to 35' of remote control range, depending upon the strength of your handheld remote. The IR pickup angle is 30° off-axis (horizontal and vertical) at 25'.

Bi-colored LED: The LED glows green when the system is on and flashes blue to confirm reception of IR commands.

Mounting: The MS220 is designed to surface-mount almost anywhere using its adhesive back. Convenient mounting locations for the MS220 include: on the front panel of a television set, on the front surface of a wall, a cabinet, an appliance, or a speaker grille.

MF1 MicroFlasher Features

Universal Compatibility: When used in a complete system, this IR MicroFlasher is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies between 20kHz and 455 kHz.

Mounting: The MF1 is designed for pin-point relaying of IR commands, so it is typically mounted to the infrared remote sensor window of an audio/video component using the self-adhesive backing. The flasher hoods can be used to block any ambient light or other remote signals. The MF1 has a transmitting range of up to approximately 4'.
