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.
