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 - 3 -
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

IRTroubleshootingGuide
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.
Model#’s
IR Receivers: Model #’s 291, 480, 490, & 780 Series
Symptom#1: DIMorNOTalkBackLEDduringIRReceptionorreducedoperationalrange
Cause: Solution
1. Weak Batteries in Transmitting Remote. Replace batteries.
2. Bad Emitter or no emitter plugged into
connecting block. Test emitter and verify wiring.
3. Signal wire between IR Receiver and the
Connecting Block is open. Recheck wiring.
4. Power Supply not putting out proper voltage.
Verify supply is a 12VDC regulated
supply reading between 11.5 to
13VDC under load. Should be using
Power Supply Model 781RG
(12VDC Regulated, 200mA) or 782-
00 (12VDC Regulated, 1.2A)
5. Output from the IR receiver/connecting block
is connected to a high impedance IR input jack
on a component.
If you are using a passive
connecting block, such as a 789-44,
and the system is not working, try
the amplified connecting block,
model 791-44. Put one of the small
plastic case jumpers supplied with
the block on the pins next to the
emitter jack. This will provide the IR-
in jack on the component with a
hotter signal.
6. IR Receiver is inoperable. Replace Receiver.
7. (XTRALINK Only) RF Amplifier is being used
on same COAX Line anywhere between the
Coupler (CPL94) and Injector (INJ94).
Need to use a Bypass Kit (model
BYPASS94 Kit) to route the IR
control signals around the
amplifier(s).

Symptom#2: TBLEDonIRReceiver(and/orEmitters)Dimlylitorflickering
Cause: Solution
1. Signal and ground wires are reversed or
shorted either at the connecting block or IR
receiver. Recheck your wiring.
2. Defective emitter. Replace Emitter
3. Relatively high levels of ambient noise. This
can be due to any of the following: Sunlight,
florescent Lighting or Plasma Displays.
In this case use either a SUN filter
(SUN480, SUN490, SUN780), or
any of our ‘CFL Friendly’ IR
Receivers (291-80, 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.
4.
EMI induced noise. This can be due to light
dimmer controls or other radiating electronic
devices (PC’s or any poorly shielded electronic
device).
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.
5. Plasma Interference
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.

Symptom#4: TBLEDonIRRec.blinksbut283Mor286M'Blink'styleEmittersdonot
Cause: Solution
1. There may be a short, such as a staple
driven through the Signal and GND wires of
the IR Receiver and/or the emitter.
Recheck your wiring.
2. Emitter may be shorted internally Replace Emitter or use TEST EMITTER
to check circuit.
3 (XTRALINK Only) TV on same splitter with
no IR Receiver installed Place a DC Blocker (Model 203-00) on any TV Leg without IR Receiver
Symptom#5: IntermittentIRcontrol(I.e. buttons on remote need to be pressed multiple times)
Cause: Solution
1. Plasma Interference Use a 490-90 Plasma 'Friendly' Receiver
2.
Relatively high levels of ambient noise.
This can be due to any of the following:
Sunlight, florescent Lighting or Plasma
Displays.
In this case use either a SUN filter
(SUN480, SUN490, SUN780), or any of
our ‘CFL Friendly’ IR Receivers (291-80,
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.
3.
Long Wire Runs – shielded wire typically of
100 feet (30 meters) or longer causes a filter
effect due to accumulated capacitance of the
wire. Intermittent, or no IR control, could
actually be because of the longer wire runs.
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.

Symptom6: Emittersfunctionbutsome(orall)componentsdonotrespond.
Cause: Solution
1. Emitter placement is incorrect.
Reposition the Emitter so that it is
directly over the components sensor
window. Consult the components
owners manual of the unit for the exact
location of the IR Sensor Window.
2. Emitter placement is correct but the signal is
overpowering the unit or there is bleed-
through from other emitters close by.
Reposition the Emitter to a position that
is suitable for the unit. Use a 283 or
286M Blink style emitter (they have a
lower output than non-blink emitters 282
and 284M). If the components do not
need to be controlled directly without an
IR Repeater system (components are
located in an equipment closet), place a
Mouse Emitter Shield cover over the
Emitter (PN#MS1). The rounded (non-
stick) side of the emitter is a hi-output
side and can reflect off other devices
and overpower some components IR
Sensors. If using a CB12 connecting
block, try a 789-44 connecting block.
This has a series resistor at the output,
which will limit current to the Emitter.
3.
Using a CFL-Friendly IR Receiver (291-80,
480-80, or 780-80) and trying to control a
unit with a carrier frequency greater then
40kHz (I.e. RCA DSS, Scientific Atlanta,
Jerald, and General Instruments Cable or
DSS Set Top Boxes).
If you are using the 291-80 or 780-80
CFL Friendly receiver, locate the Carrier
Frequency Adjustment on the unit and
using a small blade screwdriver, (3/32"
blade width max.) rotate the adjustment
for best performance of all the units in
the system. Note: The 480-80 version
does not have this feature; you will either
need to change the unit to a 291-80,
780-80 or the 490-90. The 490-90 is a
wide band unit and will not require any
frequency adjustment.

Symptom#7: AbsolutelyNoFunctionality(Howtodeterminewhichcomponentisatfault)
Step: Component to Test Instructions
1. Verify Power Supply
With a Multimeter, measure the DC
Voltage of the supply while it is
connected to the Connecting Block. Put
the Negative lead of the meter on the
terminal marked GND and the Positive
Lead on the terminal marked 12VDC (or
V). You should get a reading between
11.5VDC and 13.0VDC. If not, remove
the supply from the Connecting block
and measure again this time directly on
the 2.5mm Coaxial plug. If it reads
between 11.5VDC and 13VDC, power
supply is most likely good. Reconnect to
the Connecting Block and proceed to
step 2. NOTE: In most cases this will
indicate the supply is good but in
some cases the supply can still be
bad (i.e. reads good when not
plugged in but may not be able to
handle the current load of the
system.)
2. Verify Emitter. (283M or 286M Blink
Style ONLY)
Remove the power supply from the
connecting block and all Emitters from
the output. Place a jumper wire on the
connecting block between IR and +12v.
Reconnect the Power Supply and one
emitter. The Emitter should Light bright
and solid. Repeat for all emitters.
3. Verify Emitter. (282M or 284M NON
Blink Style)
Use a diode tester to verify proper
Emitter operation. Remove Emitter from
Connecting Block. Place the Positive
Lead of the tester on the TIP of the
Mono Mini Plug and the Negative Lead
on the Shield of the Mono Mini Plug.
Meter should read a voltage. When the
leads are reversed (Positive lead on
Shield and Negative lead on TIP) you
should not get any voltage reading at all.

08905099B - 11 -
4. Verify IR Receiver.
Remove the power supply from the
connecting block and all Emitters from
the output. Place a jumper wire on the
connecting block between IR Signal and
GND. Reconnect the Power Supply.
With a known good hand-held remote,
shoot a constant IR Command at the
receiver and verify the TB LED on the
Receiver lights.
