Set this parameter to on to enable “Code 93”.

Minimum lengths for the bar code can be set from 0 to 255. The length of a code refers to 
the number of characters (i.e., human readable characters), including check digit(s). 

Refer to “Field Size/Chars” on page 170 for details.

Set this parameter to on to enable “Codabar”.

Codabar can use the following sets of characters as start and stop characters:

a, b, c, d 

A, B, C, D 

a, b, c, d, /, t, n, *, e

DC1, DC2, DC3, DC4 

Thus, when a set is chosen, the first and last digits of a Codabar message must be one of 
those characters and the body of the message should not contain these characters. Setting 
this parameter to Not Transmitted strips the start and stop characters from this bar code. 

When enabled, spaces are inserted after characters 1, 5, 10 in the 14-character label (used in 
the USA by libraries using the CLSI system). 

When enabled, this parameter checks the integrity of a symbol to ensure it complies with a 
specified algorithm—either USS (Uniform Symbology Specification) or OPCC (Optical 
Product Code Council).

If the check digit is to be transmitted with the data, this parameter must be enabled.
