2.1.6 2D Code

Symbologies Use the parameters of the Symbologies group to activate/deactivate decoding of the indi-

vidual 2D code types.

This enables you to filter which code types are to be output:

The activated code types can be configured individually. For this purpose, separate pages

are available in the SOPAS-ET configuration software.

2.1.6.1 Data Matrix

The Data Matrix Code (DMC) was developed at the end of the 1980s by International Data

Matrix (USA) and has passed through several stages of development (ECC 0 to ECC 200).

Data Matrix Code ECC 200 is currently applied; other versions are no longer used.

Fig. 2-14: Data Matrix example

A Data Matrix Code is limited by two search elements which are used as orientation when

reading the code. Search elements are a horizontal and a vertical boundary line ("find pat-

tern") which describe the corners. The number of code modules is defined by the two inter-

rupted lines ("alternating grid") opposite the find pattern.

The size of the Data Matrix Code does not depend directly on the volume of data to be en-

coded, but on the size and number of cells. The data capacity can be up to 1558 characters

(8 bit), due to error correction ECC 200 incorrect readings are almost impossible since the

created redundancy codes can be reconstructed with up to 25% destroyed data content.
