INTRODUCTION

The 490-95 is designed to reject interference from Plasma Displays from entering the IR signal line. These Small IR

Receivers are intended to be mounted in panels, doors, cabinets, etc. for control of A/V equipment behind closed doors or

any IR Repeater System that is in close proximity of a Plasma or LCD Displays. Modeled after the original 490-90, the

490-95 offers the same features as its predecessor but in a smaller mounting frame.

FEATURES

• Small size; mounts in ¾” diameter hole. 2¾ inches deep (70mm)

• Quick-Connect 3.5mm Stereo Mini Plug on 7ft. (213.36cm) cable for direct plug-in to Xantech Connecting Blocks

• Works in normal 3-wire mode (12VDC, IR, GND)

• Green Talkback LED for System Verification

• Improved Fluorescent Light rejection (under most conditions) and rejection from LCD Displays

• Can be used in Direct Sunlight

• RF Grid included for EMI interference reduction

• Includes CB12 Connecting Block for easy connection and extension of 7' ribbon cable

• 7 units may be powered by one 781RG power supply

Note: The 490-95 will not operate in 2-wire Phantom Power mode

SPECIFICATIONS

• Infrared modulation frequency bandwidth: 30 - 100 kHz

• Reception range: up to 55 feet (17M), depending on local conditions

• Reception angle: 55 degrees off axis for 50% range reduction

• Cable requirements: 3-conductor. Use 24 gauge up to 200' (61M), 22 gauge up to 600' (182.5M), 20 gauge up to

1000' (305M), 18 gauge up to 2000' (610KM) -- unshielded OK)

• Maximum transmission length: One mile using 18 gauge wire (1.6KM)

• Maximum current output: 100 mA

• Dimensions: 0.75" diameter x 2.75" deep (19mm x 70mm)

• Power requirements: 12 volts DC @ 20 mA

Page 2 Model 490-95 INSTALLATION These units, equipped with a 7-foot cable and 3.5 mm stereo mini plug, are intended to be plugged directly into the "IR RCVR" or "AUX" jack on Xantech Connecting Blocks, such as the CB12(included), CB60, 789-44, 791-44, etc. The 49095 should be used in installations where the connecting block is within reach of the 7-foot cable -- such as when installing the 490-95 in a cabinet where the controlled equipment is behind closed doors.
