Symptom #2: IR Flashers constantly on.
Cause
1.
Plasma Interference
2.
Voltage and Ground wires are
reversed at the IR Router or IR
Receiver
3.
Relatively high levels of ambient
noise. This can be due to any of
the following: sunlight, florescent
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.
Power Supply not putting out
proper voltage.
IR TROUBLESHOOTING GUIDE
Solution
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 back into the receiving eye.
Recheck wiring.
Reposition the IR Receiver 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.
Verify supply is a 12VDC regulated supply
reading between 11.5 to 13VDC under
load. Use the included 12VDC Regulated,
500mA Power Supply.
