Barcode Configuration | Logical Combination Rule
The following are examples of rules used with Logical Combination selection in Barcode
Configuration. For all the following examples the No Read Message parameter is set to
Global No Read Message.
Example 1:
•Code label setting#1 = Code 128
•Logical Combination Rule = 1&1
•Defines 2 groups, each of them expecting a
Code 128
label.
Example 2
•Code label setting#1 = Code 39
•Code label setting#2 = Code 128
•Logical Combination Rule = 1^2
•Defines a single group expecting a Code 39 label OR a Code 128 label.

If Multiple Read Message is enabled and a third label belonging to the Code 128 symbol-
ogy is decoded, the Multiple Read string will be transmitted instead. If the Multiple Read
Message is disabled, the third code label is ignored and only the first two codes are
transmitted.
For advanced formatting, if the Send All Multiple Read Labels parameter is enabled,
then all three labels are sent in the output message; the multiple read label is separated
by its own Multiple Read Label Separator String which should be different from the Data
Packet Separator (DPS).
