NOTE All characters that are not predefined or entered in the Field Definition are treated as an
alphanumeric wildcard.
Example: The Field String entry for a SEMI M12 standard character string can be
**********CS (the default Field String setting). Any alphanumeric character is valid in the
first 10 Field String positions. But in the 11
th
position, only alpha characters A-H will be
considered during the read. And in the 12
th
position, only numeric characters 0-7 will be
considered.
NOTE When the selected Mark is a barcode, the Field String must be changed so that it is appropriate for
the selected barcode mark.
Field Definition
Optionally, the Field Definition setting can be used to create user-defined entries for the
Field String if Mark specifies a character string or barcode. When included in the Field
String, these entries restrict the list of valid characters at the positions in which they are
inserted.
!
Multiple field definitions can be used, separated by a semicolon (;).
!
Characters listed for a Field Definition entry must be contained in the font or barcode.
For example: &=123 is valid, because 1, 2, and 3 are valid characters. However,
123=& is invalid because ‘&’ is not included in the standard Semifont or barcode
character sets.
NOTE Using one of the predefined entries (*, A, N, H, D, C, S, X, dot, dash, space) in the Field Definition
will remap the list of valid characters to the new definition. Therefore, it is strongly recommended
that you do not use a predefined field definition.
Example: If the Field Definition is &=123;$=3456;%=789, and the Field String is
&$%*******CS, then the only characters that will be valid in the first position will be 1, 2, or
