LS 4071 Product Reference Guide
UCC/EAN-128
UCC/EAN-128 is a convention for printing data fields with standard Code 128
bar code symbols. UCC/EAN-128 symbols are distinguished by a leading FNC
1 character as the first or second character in the symbol. Other FNC 1
characters are used to delineate fields.
When EAN-128 symbols are read, they are transmitted after special formatting
strips off the leading FNC 1 character and replaces other FNC 1 characters with
the ASCII 29 GS control character.
When AIM symbology identifiers are transmitted, the modifier character
indicates the position of the leading FNC 1 character according to AIM
guidelines. For example, ]c1 indicates a UCC/EAN-128 symbol with a leading
FNC1 character.
Standard Code 128 bar codes which do not have a leading FNC 1 may still be
used, but are not encoded according to the EAN-128 convention. Standard
Code 128 and UCC/EAN-128 may be mixed in an application. The LS 4071
autodiscriminates between these symbols and can enable or disable one or
both code types via bar code menus. The following table indicates the behavior
of the LS 4071 in each of the four possible parameter settings.
