Code Definition
This group allows defining the following parameters, which are common to all the code symbologies.
Code Combination
The Code Combination parameter selects the decoding mode for the scanner:
Selections:
Single Label
In Single Label mode only one barcode can be read in each
reading phase, however it can be determined automatically from
up to 10 enabled codes. The scanner stops decoding as soon as a
code is read.
If the code is not read during the reading phase, the No Read
message is produced.
Standard Multi
Label
In Multi Label mode the barcodes selected (up to 10), will all be
read in the same reading phase. All the selected codes in the
reading phase must be read. If the reading phase terminates
before all the codes are read, either a Global No Read message or
a Local No Read message can be produced.
NOTE
In case of Multi Label, the codes will be distinguished
EITHER by their symbology, OR by their contents. If two
(or more) codes share the same symbology and content,
the scanner will perceive them as a unique code.
Logical
Combination
In Logical Combination mode the codes of the groups defined by
the Logical Combination Rule are read in the same reading phase.
Code Collection
In Code Collection mode expected codes are collected within a
single reading phase in the order in which they are read. The No
Read message is produced only if none of the codes are read. Up
to 50 codes can be collected.
Logical Combination Rule
It allows editing the rule which the combination of groups of labels is based upon.
Groups and their order define the output message format, while each group identifies an expected code.
When editing the logical combination rule, proceed as follows:
1.
define the
Code Label Settings #n
indicating the type of expected code labels. It is possible to define up to 10
different code types;
2.
define how many code types (groups) are expected by editing the combination rule through the following logical
operators. Each group may include one or more selected code types.
&
= AND operator which separates a group from the previous/following one;
^
= XOR operator to be used to combine different code labels within the same group. It allows reading one of the
defined code labels.
The maximum number of groups to be defined for each rule string is 15.
If setting the Local No Read Message, a further parameter group is displayed requiring the definition of a Local No
Read String for each group.
NOTE
If the syntax of the combination rule is wrong or the expected Code label settings#n is not
defined, the following message appears after sending a configuration to the reader:
