Appendix A: CODE128

A.1 Overview of CODE128
In CODE128 system, it is possible to represent 128 ASCII characters, 100 numbers from 00 to 99 and
some special characters with three code sets: A, B and C. Each code set is used for representing the
following characters:
• CODE A: ASCII characters 00H to 5FH
• CODE B: ASCII characters 20H to 7FH
• CODE C: 100 numbers from 00 to 99
CODE128 can also encode the following special characters:
• SHIFT characters
In CODE A, the character just after SHIFT is processed as a character for CODE B. In CODE B, the
character just after SHIFT is processed as a character for CODE A. The second and the following
characters recover to the code set used before SHIFT. SHIFT characters cannot be used in CODE C.
• Code set selection character (CODE A, CODE B, CODE C).
These characters can switch the following code characters to CODE A, B, or C.
• Function character (FNC1, FNC2, FNC3, FNC4)
The usage of function characters depends on the application software. In CODE C, only FNC1 is
available.
