Appendix A (Code 128)

Code 128

Code 128 can encode all the characters currently encodable in the various code formats
presently in existence. This includes: All ASCII alphanumeric characters (numbers,
letters, special characters, control characters in the 128 character set and the distinction of
the 3 subsets, A, B and C).

Code subset A includes the standard alphanumeric (upper case only) keyboard characters
plus control and special characters.

Code subset B includes all the standard alphanumeric keyboard characters and special
characters (upper and lower case).

Code subset C includes a set of 100 digit pairs from 00 to 99 inclusive, allowing definition
of double density numeric digits per symbol, plus special characters.

The last 7 characters in Subsets A and B (96 - 102) and the last 3 characters in Subset C
(100 - 102) are special characters that are specific to the scanning device.

The Inspector display can accommodate up to 16 characters. However, in order to
display symbols greater than 16 (maximum of 32), press Select to display the
additional characters.

(See Data Analysis Screens).
