Citizen Systems iDP3240 user manual This bar code consists of 103 bar code characters

CODE128	This bar code consists of 103 bar code characters
	and three code sets, enabling 128 ASCII code
	characters to be printed. It has a variable length
	of columns.
	• Code set A ASCII characters 00H - 5FH can be
		represented.
	• Code set B	ASCII characters 20H - 7FH can be
		represented.
	• Code set C	Two-digit numbers 00 - 99 can each
		be represented by one character.

In addition to the above characters, special characters are available.

• The code set following a code set select character (CODE A, CODE B, CODE C) is switched to code set A, B, or C.

• Function characters (FNC1, FNC2, FNC3, FNC4):

How the function characters are used depends on each application.

When sending print data, note these points:

(1)Each string of bar code data must begin with a code set select character (CODE A, CODE B, or CODE C), which selects the first code set to use.

(2)Every special character is specified by a combination of two characters: a brace “{” followed by one character. A brace “{” itself is sent twice consecutively.
