Bar Codes
8.1.13 MaxiCode, TCI 38
MaxiCode is a fixed-size, 2-D matrix symbology that is capable of encoding the entire ASCII
character set (0 to 255) and up to 93 characters per symbology. Modes 2 through 6 of the
AIM Internal MaxiCode specification are supported. Modes 0 and 1 are obsolete and are
not supported.
MaxiCode may encode non-printable characters, and Modes 2 and 3 require certain control
characters for compatibility with transport industry standards. In order to properly specify a
control character in a MaxiCode data string, use the pound symbol ("#") followed by the two
digits Hexadecimal value of the control code. For example, "#01" specifies "Control-A"
(ASCII SOH) and "#1D" specifies "Control-]" (ASCII GS). Enter "##" in order to include an
actual pound symbol in the data string. Refer to Table 8-2 for the "#" equivalents that may
be used.
The following is the command structure of the ^D71 which is used to load the data for
Maxicode:
^D71<CR>

Symbol Number<CR>
Total Number<CR>
