4.7 CODE 128 Barcode

The CODE 128 barcode allows a single barcode character to represent one character of a full-
ASCII 128-character set or two-digit number from among the combinations of 103 different bar
code characters and three different code sets.
• Code set A: Can represent ASCII characters 00H to 5FH.
• Code set B: Can represent ASCII characters 20H to 7FH.
• Code set C: One character can represent a two-digit number (100 numbers from 00 to 99).
In addition to the above characters, CODE 128 also provides the following special characters.
• Shift character (SHIFT)
The code set A handles the character right after SHIFT as a character of the code set B.
The code set B handles the character right after SHIFT as a character of the code set A.
SHIFT cannot be used in the code set C.
• Code set selection character (CODE A, CODE B, CODE C)
Changes the subsequent code set to A, B or C.
• Function character (FNC1, FNC 2, FNC3, FNC4)
The purpose of the function character changes depending on the application. The code
set C accepts only FNC1.
