Bar Code Information

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 P460/P360 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 P460/P360 in each of the four possible

parameter settings.
