2. Optical or Electromagnetic Interference
Direct sunlight, reflections, neon signs and other sources of
infrared light or television sets, light dimming controls and
other sources of electromagnetic fields can induce noise and
interference into your IR extender system. Symptoms can
include: flashback LED's continuously flickering or on without
any remote control use, poor range, intermittent operation or
no operation.
Solution: To eliminate EMI try the following methods:
1. Move the sensor or the sensor cable away from the EMI
source or move the source of the EMI away from the
sensor or the cable.
2. Connect the Sensor's GND terminal to true earth
ground (if this isn't feasible use the main system unit's
GND terminal).
