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

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.
PLACEMENT
Placement of the IR Receiver does matter when
used in the presence of a Plasma Display. Ideally it
should be placed at areas around the Display with
the front of the receiver flush with the front of (or
45°
PLASMA DISPLAY
45°
set back from) the Display. If the 490-95 needs to
be placed in front of the display (such as on an
adjacent side wall perpendicular to the display),
make sure it is placed at a location at least 45
degrees off axis from the corners of the unit – see
Figure 1. The presence of Direct Sunlight and
Fluorescent Lighting should not effect the
reception of this unit.
Figure 1 – 490-95 Placement
Note: Plasma interference can be reflected off of any item it comes into contact with within approx. 3 ft. from the front of
the display. Keeping this in mind, make sure that the 490-95 is free of any obstruction that might reflect back into the
receiving eye.
Note: While this unit shows strong rejection to standard 50/60Hz ‘ballasted’ fluorescent lighting, it is still prone to
interference from CFL style Fluorescent lighting.
MOUNTING
1. Drill a 0.75” (19mm) hole in any flat surface, such as a cabinet panel.
2. Pass the lead and the body of the 490-95 through the hole.
3. Secure from the rear with the Washer and Nut (all supplied) as shown in Figure 2a. Be sure not to over-tighten
nut.
