LONG CABLE RUNS
When using long lengths of cable (>50 ft.), it may be necessary to
connect a 470 Ohm 1/8 Watt resistor between IR IN (signal) and
GND. The resistor discharges the cable capacitance, which allows
high bit-rate IR codes to work with higher reliability.

outputs 5 and 6 by setting the switches located next to the Emitter
outputs
2.3. TROUBLESHOOTING
When multiple IR Receivers are used in a system, the potential
for increased IR noise exists. This may affect the reliability of the
system and reduce the range of the IR. If this occurs, remove the
IR Receivers one at a time to determine the maximum number for
the installation.
