National bodies that are members of ISo or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISo and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and lEC have established a joint technical committee, ISO/EC JTC 1 International Standards are drafted in accordance with the rules given in the ISo/EC Directives, Part 2 The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting Publication as an International Standard requires approval by at least 75 of the national bodies casting a vote Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. Iso and IEC shall not be held responsible for identifying any or all such patent rights ISO/EC 16022 was prepared by Joint Technical Committee ISO/EC JTC 1, Information Technology, Subcommittee SC 31, Automatic identification and data capture techniques This second/third/. edition cancels and replaces the first/second/. edition (, [clause(s)/ subclause(s)/ table(s)/figure(s)/ annex(es)] of which [has /have] been technically revised Annexes a through n of this International Standard are normative; Annexeso through t are informative O ISO/EC 2005-All rights reserved ISO/EC FCD 16022 Introduction Data Matrix is a two-dimensional matrix symbology which is made up of nominally square modules arranged within a perimeter finder pattern. Though primarily shown and described in this document as a dark symbo on light background, Data Matrix symbols can also be printed to appear as light on dark Manufacturers of bar code equipment and users of the technology require publicly available standard symbology specifications to which they can reter when developing equipment and application standards. The publication of standardised symbology specifications is designed to achieve this O ISO/EC 2005-All rights reserved ISO/EC FCD 16022 Information technology-Automatic identification and data capture techniques- Bar code symbology specifications Data matrix 1 Scope This International Standard defines the requirements for the symbology known as Data Matrix. 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 It applies to all Data Matrix symbols produced by any printing or marking technology 2 Normative references The following referenced documents are indispensable for the application of this document.

An intermediate level of coding between source data and the graphical encodation in the symbol 3.12 module single cell in a matrix symbology used to encode one bit of data. In Data Matrix the module is nominally a square shape 3.13 convolutional coding error checking and correcting(ECC) algorithm that processes a set of input bits into a set of output bits that can recover from damage. The encoding process consists of breaking the input bits into blocks, then convolving each input block with the contents of a multi-stage shift register to produce protected output blocks These encoders can be constructed in hardware using input and output switches, shift registers, and exclusive-or(XOR) gates 3.14 pattern randomising procedure which converts an original bit pattern to another bit pattern by inverting selected bits. The resulting bit stream is less likely to have repeating patterns 3.2 Symbols and abbreviations For the purposes of this International Standard, the mathematical symbols which follow shall apply globally unless defined locally d number of error correction codewords e number of erasures k (for ECC 000-140the number of bits in a complete segment input to the state machine to generate the convolutional code(for ECC 200)total number of error correction codewords m the memory order of the convolutional code n( for ECC 000- 140) the number of bits in a complete segment generated by the state machine producing the convolutional code(for ECC 200) total number of data codewords n the numerical base in an encodation scheme p number of codewords reserved for error detection s symbol character t number of errors u the input bit segment to the state machine, taken k bits at a time v the output bit segment from the state machine, generated n bits at a time X horizontal and vertical width of a module E error correction codeword O ISO/EC 2005-All rights reserved
