Composite
Code
EAN.UPC bar codes can have an additional 2D Composite code component append-
ed. If ’Composite Code’ is set to ’CCA/B’ the composite component will be found and
decoded. By default, ’Composite Code’ is set to ’none’ and thus it is disabled. If the
searched bar code symbol has no attached composite component, just the result of
the bar code itself is returned. Composite codes are supported only for bar codes of
the RSS family. List of values: [’none’, ’CC-A/B’] Default: ’none’
UPCE Encodation
For UPC-E bar codes, different output formats can be used. By default, ’UPCE En-
codation’ is set to ’ucc-12’ and the decoded string will be returned in UCC-12 format
(consisting of 12 digits). If ’UPCE Encodation’ is set to ’zero-suppressed’, the result will
be returned in zero-suppressed format (with suppressed zeros at defined places). This
format consists of a leading zero, six encoded digits, and an implicitly encoded check
digit. This corresponds to the format demanded by ISO/IEC 15420 standard.
List of values: [’ucc-12’, ’zero-suppressed’] Default: ’ucc-12’
11.12. Module Code 2D
11.12.1. Overview
Objective
All common 2D codes can be read with the 2D code module.
The following 2D codes can be read:
• Data Matrix ECC 200
• QR Code
• PDF417
Prerequisites
1. Sensor is correctly connected (see section 5.5)
2. Connection has been established from the sensor to the software
(see section 10.1.1)
3. The camera is configured / images are selected (see section 11.2)
Procedure
An object with a corresponding 2D code is read.
