selected, the Strip Filter parameters will apply.
Filter Type
Select Normal or Advanced from the drop ‐ down list.
Description:
Normal: Uses the Logical Combination Rule string to define the priority
Advanced: Uses the Priority Filter Advanced String to define the priority. Advanced type allows
the priority filter to essentially take "priority" over the Logical Combination Rule string.
NORMAL
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
Results With Priority Filter:
Filter Enabled on Groups = 1,2
Group 1 ‐ read code 1 = Good Read independent from reading code 2
Group 2 ‐ read code 5 = Good Read independent from reading code 3 or 4; read code 3 = Good
Read independent from reading code 4
Group 3 ‐ read either code 6 or 7 = Good Read; read both code 6 and 7 = Multiple Read
ADVANCED
When the Priority Filter Type is set to Advanced, the Priority Filter Advanced String applies to
the Logical Combination Groups. This string must correspond to the order of the groups
defined in the Logical Combination Rule string.
The following operators can be used:
& = Code group separator. This operator separates a group from the previous/following one;
^ = The priority is given to the code label indicated to the left of this operator. If this code is
read, the group is in Good Read independent from any other code in the same group.
| = Equal priority operator (vertical line). Codes separated by this operator have the same
priority and if both codes are read a Multiple Read will result.
The only difference from the implicit pattern string of the Normal (default) case when the
Logical Combination Rule string is used, is the Equal Priority operator.
Example:
Logical Combination Rule = 1^2&5^3^4&8^6^7 (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 8 or 6 or 7 = Good Read; read any combination = Multiple Read
Results With Priority Filter:
Filter Enabled on Groups = 1,3
Filter Type =Custom
Custom Filter Pattern String = 1^2&8^6|7 (2 groups)
Group 1 ‐ read code 1 = Good Read independent from reading code 2
Group 2 ‐ read either code 5 or 3 or 4 = Good Read; read any combination = Multiple Read
Group 3 ‐ read code 8 = Good Read independent from reading code 6 or 7; no read on code 8
and read either code 6 or 7 = Good Read; no read on code 8 and read both code 6 and 7 =
Multiple Read
