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.

Please Click on the Link below that best describes your symptom:

Symptom #1: DIM or NO Talk Back LED during IR Reception or reduced operational range

Symptom #2: TB LED on IR Receiver (and/or Emitters) Dimly lit or flickering

Symptom #3: TB LED on IR Receiver (and/or Emitters) on solid

Symptom #4: TB LED on IR Rec. blinks but 283M or 286M 'Blink' style Emitters do not

Symptom #5: Intermittent IR control (I.e. buttons on remote need to be pressed multiple

times)

Symptom #6: Emitters function but some (or all) components do not respond.

Symptom #7: Absolutely No Functionality (How to determine which component is at fault)

Model #’s

IR Receivers: Model #’s 291, 480, 490, & 780 Series Receivers

Symptom #1:

DIM or NO Talk Back LED during IR Reception or reduced operational range

Cause: Solution

Weak Batteries in Transmitting Remote. Replace batteries.

Bad Emitter or no emitter plugged into

connecting block.

Test emitter and verify wiring.

Signal wire between IR Receiver and the

Connecting Block is open.

Recheck wiring.

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)

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.
