Appendix B (Code 93)

Code 93

Code 93 encodes 43 data characters consisting of 0-9, A-Z,

6 symbols, 4 control characters and a unique start/stop character.

The entire 128 ASCII character set is represented in code 93 using combinations of control

characters and basic data characters.

Each symbol includes 2 check characters. The symbols are checked by the Laser Inspector

and displayed on the Mod Check Data Analysis screen.

* C 9 3 A › *

The 2 check characters are referred to in the USS-Code 93 specifications as “C” and “K.”

They are displayed in that order on the Data Analysis screen.

The entire Code 93 character set is shown in Table B-1. The Laser Inspector displays the

characters shown in the columns labeled Code 93 in the figure. Remember, some ASCII

characters require 2 Code 93 symbol characters.

The Start/Stop and control characters cannot be displayed on the LCD as shown in Table

B-1. They are displayed as:
