480-95

Plasma Friendly Dinky Link IR Receiver

DESCRIPTION

The 480-95 is a Plasma Friendly version of the 480-00 series Dinky Link IR receivers. It is specifically
designed to have greater immunity to plasma infrared inference and to have exceptional IR reception
range. Besides showing great immunity to plasma emissions, the 480-95 (as well as all Xantech
Plasma-Friendly Receivers) work well in the presence of Sunlight and Fluorescent lighting. Their
wide-bandwidth reception allows them to be used with a much wider assortment of IR Controllable
products that the competition assuring the ‘job will get done’ the first time around without un-wanted
service calls.

These small IR receivers have been designed for mounting in very small spaces. They may be
mounted under shelf edges, cabinet ledges, in-wall speakers, etc. anywhere an inconspicuous
appearance is desired. The high sensitivity of these receivers allows placement behind speaker
grilles and still receive IR commands up to 20 feet away. If longer range is necessary, a 3/8-inch hole
must be drilled in the grilled to allow unobstructed entry of the IR signal.

FEATURES

 Black, silver, and white color available.
 Works in normal 3-wire mode (12VDC, IR, GND).
 Red talkback LED for system verification.
 Improved Fluorescent light rejection (under most conditions) and rejection from LCD

Displays.

 Includes 3-Terminal Block for easy extension of 7 foot ribbon cable.
 7 units may be powered by one 781RG power supply.
 Normal Operating Power: +12VDC, 20mA.

Note: The 480-95 will not operate in 2-wire Phantom Power mode.

SPECIFICATIONS:

INSTALLATION

This unit is meant to be interfaced to Xantech Connecting Blocks, such as CB12, 789-44, 791-44, etc.

PLACEMENT

Placement of the IR Receiver does matter when used in the presence of a Plasma Display. Ideally it
should be placed somewhere around the Display with the front of the receiver flush with the front of
the Display. If the 480-95 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. The presence of Direct Sunlight and Fluorescent Lighting should not effect the
reception of this unit.

08905099B - 2 -

Note: Plasma interference can be reflected off of any item it comes into contact with approx. 3 feet
from the front of the display. Keeping this in mind, make sure that the 480-95 is free of any
obstruction that might reflect back in to 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. The 480-95 can be mounted to almost any surface using the included double-sided foam tape.

2. Connect proper wires to the +12VDC, GND, and IR to the Xantech Connecting Block.

3. For wire runs longer than 7 feet, use the included 3-terminal screw block to extend wiring runs.

SENSITIVITY ADJUSTMENT

The 480-95 is preset at the factory for optimal performance. However, some conditions may require
fine tuning. Carefully remove the plastic circular cap to access the sensitivity potentiometer. The
potentiometer is a highly precise and sensitive component, please be gentle when accessing and
turning the potentiometer. The factory default is 12 o’clock position.

Clock-wise (CW) Increase sensitivity
Counter Clock-wise (CCW) Decrease sensitivity

APPLICATION WIRING

A typical system, with a 480-95, 781RG Power Supply and 283M Emitter plugged into a 789-44
Connecting Block, is shown in the figure below.

1. Wire the appropriate leads of the 3 conductor cable to the +12VDC, GND, and IR terminals on
the 789-44 Connecting Block.

2. Plug in the 3.5 mm mono mini plug from any of the 282, 284, 283 and 286 series Emitters into
the jacks labeled EMITTERS on the 789-44 Connecting Block and affix the opposite end of the
IR Sensor Window of the controlled equipment.

3. Plug in the 2.1mm Coaxial power plug of the 781RG Power Supply (not included) into the jack
labeled 12VDC on the 789-44 Connecting Block.

4. Plug the AC end of the 781RG Power Supply into an ‘un-switched’ 120VAC outlet.

ADVANCED WIRING CONFIGURATION

480-95 may also be used in conjunction with other Xantech IR Receivers by simply wiring in parallel
on a Connecting Block such as the 791-44 Amplified Block as shown in the figure below.

1. Connect all IR Receivers in parallel at the terminals of the connecting block as shown in the
figure below.

2. Plug in the 2.1mm Coaxial power plug of the 781RG (or 782) Power supply (not included) into
the jack labeled PWR on the 789-44CB.
Note: Up to 7 IR Receivers may be connected in parallel with a single 781RG power supply. If
more IR Receivers or any Keypads are required, check total current requirements and
increase power supply current rating accordingly; i.e. 782-00 – 1.2A Power Supply)

3. Plug in the Emitters 3.5mm mono mini plug (282, 284, 283 or 286 series) into the Emitter
Outputs on the 791-44.

IR Troubleshooting Guide

NOTE: Due to the many variables in a given installation, the troubleshooting countermeasures you will
have to take may vary from job to job. Each installation is different due to the number of IR receivers in
use, length of wire runs, type of wire, amount of ambient IR noise present, etc…. Therefore, your
countermeasures for a particular job will range from nothing at all, to any combination of the solutions listed
below.

For Plasma Interference use the
490-90 or 780-90 ‘Plasma Friendly’
IR Receivers. These can also be
used in direct sunlight and in the
presence of ‘tube style’ florescent
lighting.

Reposition IR Receiver and/or
cabling away from emitting device.
You can also place a 470Ohm
resistor in parallel with the IR Signal
and GND connections on the
connecting block. This will also help
alleviate any stray capacitance in the
cable.

Use a 490-90 Plasma 'Friendly' IR
Receiver. If already using a 490-90
unit, please note the Plasma
interference can be reflected off of
any item it comes into contact with
within approx. 3ft. From the front of
the display. Keeping this in mind,
make sure that the 490-90 is free
from any obstruction that might
reflect back into the receiving eye.

480-80, 780-80). For Plasma
Interference use the 490-90 or 780-90
‘Plasma Friendly’ IR Receivers. These
can also be used in direct sunlight and in
the presence of ‘tube style’ florescent
lighting.

Putting a 470-ohm resistor in parallel at
the connecting block between signal and
ground will effectively discharge the
capacitance of the wire. This will allow
the signal to travel farther on shielded
wire. Adding a resistor between the
input and ground of the connecting block
will drop the IR level down somewhat.
Passive connecting blocks, such as the
789-44, may not have enough signal
output for consistent control of the
equipment. You may have to upgrade to
an amplified connecting block to bring
the IR level back to normal. In these
cases, the 791-44 would be an ideal
connecting block for single zone
systems while the 795-20 would work
best for a 2-4 zone system.
