Due to the flexibility and nature of Code 128, it is difficult to display “printable” and

“non-printable” control codes side by side without confusion. However, the approach

taken here (detailed below) simplifies the displaying of this information.

 As indicated before, each of the 3 subsets have “unique” features:

 Subset A allows for encodation of control codes but not lower case characters.

 Subset B allows for lower case characters but not control codes.

 Subset C allows for only numeric data in a compressed format.

Code 128 also offers the flexibility to “shift” to other subsets in order to combine the

“unique” features into one condensed bar-code.

The encoded data occupies 2 rows on the LCD and is encoded in a columnar display

with one character above the other.

Display of Code 128 (Rules)

• The first character (column) displays the subset (*A = Subset A).

• The last character is a stop code (**).

• The second from the last is a mod 103 check character.

• Double characters beginning with alphanumeric characters designate non-printable

control codes applicable to all subsets.

• Double numeric characters designate the compressed digit mode in subset C only.

• Single characters will always be displayed on the lower row and are applicable to

only subsets A and B (normal printable characters.)
