Each code set is used for representing the following characters : * Code set A : ASCII characters 00H to 5FH * Code set B : ASCII characters 20H to 7FH * Code set C : 2-digit numeral characters using one character (100 numerals from 00 to 99) The following special characters are also available in CODE128 : * SHIFT characters In code set A, the character just after SHFIT is processed as a character for code set B. In code set B, the character just after SHIFT is processed as the character for code set A. SHIFT characters cannot be used in code set C. * Code set selection character (CODE A, CODE B, CODE C) This character switches the following code set to code set A, B, or C. * Function character (FNC1, FNC2, FNC3, FNC4) The usage of function characters depends on the application software. In code set C, only FNC 1 is available. ② Special characters are defined by combining two characters "{" and one character. The ASCII character "{" is defined by transmitting "{" twice consecutively.

Be sure to keep spaces on both right and left sides of a bar code. (Spaces are different depending on the types of the bar code.) 48 49
