12、ialized system for worldwide standardization. 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 c

13、ommittees 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 IEC have established a joint technical committee, ISO/IEC JTC 1. Internat

14、ional Standards are drafted in accordance with the rules given in the ISO/IEC 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.

15、 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 shall not be held responsible for identifying any or all such

16、patent rights. ISO/IEC 15424 was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This second edition cancels and replaces the first edition (ISO/IEC 15424:2000), which has been technically revised.

17、ISO/IEC 15424:2008(E) ISO/IEC 2008 All rights reserved v Introduction The need exists to identify the data carrier a reader detects in autodiscrimination environments. The Symbology Identifier concept provides a standardized way for a device receiving data from a reader to differentiate between the

18、data carriers. This International Standard deals mostly with bar code symbologies; the terms Symbology Identifier, symbology, and bar code are therefore used throughout this International Standard although they are intended to apply to other data carriers as well. This identification is achieved by

19、the addition of an optional feature to readers enabling the reader to prefix a standard string of characters to data messages. This preamble contains information about the decoded symbol (or other data carrier) and any processing the reader has done. The information is not encoded or otherwise expli

20、citly or implicitly represented in the symbol, except that the presence of some optional features may be detected by the reading equipment, whereas others require the reader to be expressly configured to implement them. This International Standard is intended to be read in conjunction with the relev

21、ant symbology specifications.

It specifies a preamble message generated by the reader and interpretable by the receiving system, which indicates the bar code symbol

30、dentifies symbologies for which a symbology specification has been published by ISO/IEC JTC 1, AIM Global, or another recognized international standards body. In addition there is a fixed number of symbologies which do not have a full standard but do have a reference document available from AIM Glob

31、al. These symbologies are included in this International Standard because of their historical usage. 4.2 Structure The symbology identifier shall be an ASCII character string prefixed by the reading equipment to the data contained in a bar code symbol. The structure of the symbology identifier strin

32、g shall be as follows: cm. where (ASCII value 93) represents the symbology identifier flag character; c represents the code character as defined in Table 1; m. represents the modifier character(s) as defined for the symbology in question. NOTE The sign is the character assigned to ASCII value 93 in

33、the United States ASCII character set in accordance with ISO/IEC 646. If a reader is enabled to transmit symbology identifiers, it shall always transmit a symbology identifier at the beginning of each message. The application must know whether or not the reader has symbology identifiers enabled. The

34、refore, the symbol data may start with a and still be interpreted unambiguously. When these ASCII characters are transmitted in a 16-bit (double byte) system, an 8-bit byte of all zeros shall be transmitted before each of the above ASCII characters (bytes). ISO/IEC 15424:2008(E) ISO/IEC 2008 All rig

35、hts reserved 3 4.3 Code characters Code characters shall be drawn from the set of upper- and lower-case alphabetic letters A through Z (ASCII values 65 through 90) and a through z (ASCII values 97 through 122). The currently assigned code characters are listed in Table 1. These code characters are c

36、ase sensitive, i.e. a capital “A” is a different code character from a lower case “a”. The code character Y is not assigned to a specific symbology but will be used for system expansion. The first modifier character following Y will be a digit from 1 to 9 defining the number of remaining modifier ch

37、aracters in the symbology identifier prefix string. All code characters not given here are reserved for future use. Maintenance of the list of code characters (and of options given in 4.3) shall be in accordance with annex A of this International Standard. Certain symbologies emulate the data conten

38、t of other symbologies, using their assigned symbology identifier. See annex B. Table 1 Code characters Code char. Symbology Code char.

41、4.4 Modifier characters Some symbologies covered by this International Standard contain optional features which need to be indicated to the receiving equipment to enable them to be correctly processed. This optional processing is indicated by the modifier character(s). Each symbology has a different

42、 set of optional features. These are listed in the following subclauses. ISO/IEC 15424:2008(E) 4 ISO/IEC 2008 All rights reservedTo determine the modifier character(s) for an application, refer to the subclause corresponding to the symbology concerned. Listed in this subclause may be one or more pro

43、cessing options, each of which has an assigned option value. The precise interpretation of the option should be obtained by reference to the relevant symbology specification. The modifier characters define the options available for the code character. The number of modifier characters and their mean

44、ing is defined for each of the code characters. The first modifier character shall be from the set 0 to 9, A to Z, a to z; in some instances the character may represent a hexadecimal value (0 to F) corresponding to the sum of active processing options. Where no options are indicated in the subclause

45、s, the modifier character to be transmitted is 0. Values which are not included in the modifier values of a subclause are reserved for future use. Check character options listed in the subclauses below indicate the basis of calculation of the check character, where a check character algorithm has be

46、en defined in the symbology specification or reference document. Symbologies that support the ECI protocol have one or more modifiers to indicate that the ECI protocol is being used. Unless otherwise stated, the default ECI interpretation for these symbologies is 000003. 4.4.1 Code 39 Code character
