1 Scope
This internationa Standard applies to automatic identification device communication conventions andstandardizes the reporting of data carriers from bar code readers and other automatic identification equipmentit specifies a preamble message generated by the reader and interpretable by the receiving system, whichindicates the bar code symbology or other origin of transmitted data, together with details of certain specifiedoptional processing features associated with the data message

4.1 Applicability
This International Standard identifies symbologies for which a symbology specification has been published bySO/EC JTC 1, AlM Global, or another recognized international standards body. ln addition there is a fixednumber of symbologies which do not have a full standard but do have a reference document available fromAIM Global. These symbologies are included in this lnternational Standard because of their historical usage.
4.2 Structure
The symbology identifier shall be an ASCll character string prefixed by the reading equipment to the datacontained in a bar code symbol.
The structure of the symbology identifier string shall be as follows:
]cm…
where(ASCll value 93) represents the symbology identifier flag character;
represents the code character as defined in Table 1:C
m… represents the modifier character(s) as defined for the symbology in question.
