AIM Internal MaxiCode specification are supported. Modes 0 and 1 are obsolete and are
not supported. The CGN parameter is used to select the desired mode (2-6) of the
symbology.
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 15 for the “#” equivalents that may
be used.
The data string associated with a MaxiCode field shall be formatted according to the Mode
selected (2-6).
