Group Multiple Read Messages
Define a string for each group’s multiple read string.
Multi-Filter Settings
Strip Filter
Select the check box to display the Strip Filter Settings options. This filter, when enable, allows
eliminating characters not managed by the host.
Strip All Non Printable Chars
Select the check box to remove all non- printable ASCII characters from the code (000-020 and
127).
Char(s) to be Stripped
Click to activate the Text Entry Tool and enter specific characters to be stripped from the
code. Click Submit to save your text to the origin window text field, or click Cancel to return to
origin window without transferring text.
Strip Filter Collapse
Select the check box to remove the stripped characters from the code and, therefore, reduce
the code length (collapsed). It can even be null.
Replacement Char
Click to activate the Text Entry Tool and enter the substitution character to replace all the
stripped ones. Click Submit to save your text to the origin window text field, or click Cancel to
return to origin window without transferring text.
Priority Filter Settings
Select the check box to display the Priority Filter options. This function allows the user to
prioritize barcodes.
Example:
If there is a message with a field that should contain one of multiple code types (for example,
Code128, Code39 and I2of5). In this field, the user wants:
If Code 128 is read, it goes in the field (any code39 and I2of5 are ignored)
If Code 128 is not read – if Code39 is read, it goes in the field (and I2of5 is ignored)
If Code 128 and Code30 are not read – if i2of5 is read, it goes in the field.
Group List
Enter the Group List in the field provided. This field defines the specific Logical Combination
groups to which the Priority Filter will apply. The groups are numbered according to the order
in which they are listed (from left to right) in the Logical Combination Rule parameter.
Format: Group Number(s) separated by the comma character
Example:
1,3 means the Priority Filter is applied to Logical Groups 1 and 3. Logical Group 2 will not have
the Priority Filter applied, however it will follow the normal rules of code analysis, and if
selected, the Strip Filter parameters will apply.
Filter Type
Select
Normal
or
Advanced
from the drop-down list.
NORMAL: Uses the Logical Combination Rule string to define the priority
When the Priority Filter Type is set to Normal, the operators used in the Logical Combination
Rule string have the following meaning:
& = AND operator which separates a group from the previous/following one;
^ = The priority is given to the code label indicated to the left of the operator. If this code is
read, the group is in Good Read independent from any other code in the same group.
Example:
Logical Combination Rule = 1^2&5^3^4&6^7 (3 groups)
Results Without Priority Filter:
Group 1 - read either code 1 or 2 = Good Read; read both code 1 and 2 = Multiple Read
Group 2 - read either code 5 or 3 or 4 = Good Read; read any combination = Multiple Read
Group 3 - read either code 6 or 7 = Good Read; read both code 6 and 7 = Multiple Read
