■ EAN-128 reading specifications
The BL-600 Series operates as follows if “EAN-128 support” is selected using the
setup software.
➮ See page 52.
• The header of the EAN-128 data is always the combination of a “Start code A to
C” and “FNC1” (Start pattern). A reading error occurs when another item is
used.
• “FNC1” (separator) is used at the end of each set of data that has a variable
length to separate the data. “FNC1” is replaced with character [GS] (“1Dh” of
ASCII code) for output.
