Multiple Read String (max. 128 chars)
Click to activate the Text Entry Tool and create a string to be displayed in case
of Multiple Read Message. Click Submit to save your text to the origin window text
field, or click Cancel to return to origin window without transferring text.
This parameter is only available when Multiple Read Message is enabled and the No
Read Message selection is different from Local No Read(s) String. It is possible to
select either the ASCII or HEX value. If disabled, the scanner transmits the first code
read.
Send All Multiple Read Labels
Select Enable or Disable. For Advanced Data Formats only, by enabling this
parameter all multiple read labels will be included in the output message. They can
be separated by the Multiple Read Separator.
Multiple Read Label Separator String (max. 128 chars):
The Multiple Read Label Separators (up to 128 bytes) are used to separate multiple
read barcodes in the reading phase.
This is meaningful when the Code Combination parameter is set to Multi Label or
Logical Combination and the Send All Multiple Read Labels parameter has been
enabled.
If selected, they occur within the Code Field and are transmitted after each decoded
multiple read barcode.
Multi Filters
Select the check box to display the Multi-Filter Settings options.
Multi-Filter Settings
Contained Filter
Select the check box to reveal the Max Number of Different Characters field.

When checked, this filter attempts to eliminate false multiple reads by determining
if a short code read is "contained in" (is a sub-string of), another longer code read.
This condition implicates that the short code is probably a misread of the same
longer code and therefore 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
all decoded codes of the same type are compared with each other
Rule 1: the shorter code is considered contained in the longer code if the character
string is found in the same order; the longer code may have a single block of
characters in any position (before, after or in between the compared strings)
Example: The code 123456 is considered contained in the following codes:
00123456, 12345600, 12378456.


The code 123456 is not considered contained in the following codes: 12346507
(string out of order), 12345700 (string not complete), 120378456 or 0012345600
(multiple blocks in the string).
Rule 2: the shorter code is not filtered by rule 1. In the longer code, all possible
sub-strings of the same length as the shorter code string are compared with the
shorter code string. The shorter code is considered contained in the longer code if
the number of different characters between the compared codes is less than or
equal to the Max Number of Different Characters. The shorter code will be filtered
by rule 2.
