IR TROUBLESHOOTING GUIDE
NOTE: Due to the many variables in a given installation, the troubleshooting measures
you may need to take can vary in different situations.
Each installation is different due to the number of IR Receivers, length of wire runs, type
of wire, amount of ambient IR noise present, etc....
Therefore, your troubleshooting measures for a particular job can range from nothing at
all, to any combination of the solutions listed below.
Symptom #1: IR Flashers dimly lit or flickering.
Cause
1.
Signal and ground wires are
reversed or shorted either at the
IR Router or IR Receiver.
2.
Defective Flasher.
3.
Relatively high levels of ambient
light noise. This can be due to any
of the following: sunlight, flores-
cent lighting or Plasma Displays.
4.
EMI induced noise (electromag-
netic interference). This can be
due to light dimmer controls or
other radiating electronic devices
(PC's or any poorly shielded elec-
tronic device).
5.
Plasma Interference.
Solution
Recheck wiring.
Replace Flasher.
Reposition the IR Receiver away from the
light source or eliminate the light source.
Reposition the IR Receiver and/or cabling
away from emitting device. You can also
place a 470-ohm resistor in parallel with
the IR Signal and GND connections on
the IR Router. This will also help alleviate
any stray capacitance in the cable.
Plasma interference can be reflected off
of any item it comes into contact with
within approx. 3 feet of the front of the
display. Keeping this in mind, make
sure that the IR Receiver is free from any
object that might reflect Plasma interfer-
ence into the receiving eye.
