Select the check box to reveal the Max Number of Different Characters field.
When selected, this filter attempts to eliminate false multiple reads by
comparing the number of different characters by position between two codes
of the same type and length. This condition implicates that reading a code of
the same type and length having very few different characters is probably a
misread of the code itself and therefore the code read the least number of
times should be ignored, (should not be considered as a multiple read of a
different code).
This filter is based upon the following rules:
 a multiple read condition occurs;
 the two codes are of the same type;
 the two codes have the same length;
 the number of different characters by position is equal to or less than the
number defined by the Max Number of Different Characters parameter;
 Message Tx Selection (see section 3) must be set to After Reading
Phase Off.

Background: This option was developed for the airports systems where
there are often tall bar height codes and low bar height codes with the same
content attached to baggage. Travelers will often remove the large, tall bar
height code, while leaving the smaller, low bar height codes attached to the
bag. The next time they travel they may have multiple low bar height codes
on their baggage plus the new tall bar height and low bar height codes for
the new trip.
This option instructs the system to ignore low bar height codes, which are
likely read only once or twice, in favor of tall bar height codes, which will
likely be read multiple times.
This is used in tunnel applications where multiple barcodes are read and
there is a need to filter out one of the barcodes. If less than
scanners read the barcode, then it will be considered a NOREAD for that
code.
Enter the minimum number of scanners that must read a barcode for it to be
considered a valid read.
With the check box selected, if only 1 scanner reads a code it will be
considered a NOREAD.
Select the check box to display the Strip Filter Settings options. This is a
second level filter that when enabled allows eliminating characters not
managed by the host.
