Comparison pa-
rameter bar
code content
If this criterion has been activated,
the bar code content is used to
determine whether the bar codes
are identical.

Comparison pa-
rameter bar
code direction
If this criterion has been activated,
the bar code direction is used to
determine whether the bar codes
are identical.

Comparison pa-
rameter scan
position
If this parameter is not equal to 0,
the bar code position in the scan-
ning beam is used to determine
whether identical bar codes have
already been decoded. In this
case, a +/- bandwidth must be
specified in 1/10 degrees, within
which the same bar code is per-
mitted to be in the scanning
beam.

Comparison pa-
rameter scan-
ning time info
If this parameter is not equal to 0,
the decoding time (time at which
the bar code was decoded) is
used to determine whether identi-
cal bar codes have already been
detected. For this purpose, a time
difference in milliseconds is speci-
fied. It ensures that identical bar
codes can only occur within this
time.

All comparison criteria are AND linked; this means all active comparisons must be fulfilled before the just-
decoded bar code can be identified as already decoded and then deleted.
