10.9.1 Module 50 – Characteristics filter
Description
Configuration of the characteristics filter. This filter can be used to set how bar codes with identical content
are handled and what criteria are to be taken into account in determining the likeness.

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.

parameter - scan
position
If this parameter is not equal to 0, the bar code
position in the scanning beam is used to deter

mine whether identical bar codes have already
been decoded.
In this case, a +/- bandwidth in degrees must
be specified, within which the same bar code is
permitted to be in the scanning beam.

If this parameter is not equal to 0, the bar code
position in the swivel range of the oscillating
mirror is used to determine whether identical
bar codes have already been decoded. A +/-
bandwidth in degrees must then be specified,
within which the same bar code is permitted to
be in the oscillating mirror swivel range.

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 identical bar
codes have already been detected. Here, a dif

ference time specified in milliseconds ensures
that identical bar codes may only occur within
this time.
