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

APPLICATION WIRING

A typical system, with a 480-95, 781RG Power Supply and 283M Emitter plugged into a 789-44

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

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.

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

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

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.

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.

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.
