Every Data Matrix is composed of two solid adjacent borders in an “L” shape called the “finder pattern” and two other borders consisting of alternating dark and light iex or modules called the “timing pattern”.

Data Matrix symbols are rectangular, usually square in shape and composed of square “cells” which represent bits. Wikimedia Commons has media related to DataMatrix. A German patent application DE was filed inand published in Official ZXing “Zebra Crossing” project home”.

For industrial engineering purposes, Data Matrix codes can be marked directly onto components, ensuring that only the intended component is identified with the data-matrix-encoded data.

The length of the encoded data depends on the number of cells in the matrix. As more data jec encoded in the symbol, the number of cells rows and columns increases. As an added measure, the placement of each bit in the code is determined by bit-placement tables included in the specification. The message is “Wikipedia”, and it is arranged in a somewhat complicated diagonal pattern starting near the upper-left corner.

All symbols utilizing the ECC through error correction can be recognized by the upper-right ief module isp the inverse of the background color. C40 is primarily upper-case, with lower-case letters in Set 3. While the ruling was delivered after the patent expired, it precluded claims for infringement based on use of Data Matrix prior to November Set 0 is the default, and contains codes that temporarily select a different set for the next character.

Cognex Corporationa large manufacturer of 2D barcode devices, filed a declaratory judgment complaint on 13 March after receiving information that Acacia had contacted its customers demanding licensing fees. For other uses, see Data matrix disambiguation. It specifies the Data Matrix symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters.

The modules may be ie or square- no specific shape is defined in the standard. Although the majority of these mobile readers are isc of reading Data Matrix, [ citation needed ] few extend the decoding to enable mobile access and interaction, whereupon the codes can be used securely and across media; for example, in track and trace, anti-counterfeit, e.

For each product run the unique code is supplied to the printer. Suing for Business Defamation”. Each data region is delimited by a finder pattern, and this is surrounded on all four sides by a quiet zone border margin.

A length of 1 to is encoded as a single byte, and ice lengths are stored as two bytes. Manufacturers of bar code 16202 and users of the technology require publicly available standard symbology specifications to which they can refer when developing equipment and application standards.

For example, dot-peened cells are generally round.

The encoding process is described in documents published by ISO web site. Unsourced material may be challenged and removed.

From Wikipedia, the free encyclopedia. Printed Circuit Design and Manufacture. On ic May Judge Joan N. Control codes are provided to switch between modes, as shown below. Also shown are the end-of-message code marked Endthe padding P and error correction E bytes, and four modules of unused space X.

Usual data size is from a few bytes up to bytes. Character code interpretations are shown in the table below. The publication of standardized symbology specifications is designed to achieve this.

Some characters are split in two pieces, such as the initial W, and the third ‘i’ is in “corner pattern 2” rather than the usual L-shaped arrangement.
