Appendix D: Bar Code Settings
Codabar
Start/Stop Transmit
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 off strips the start and stop characters from this bar code.
Check Char
When this parameter is set to Validate only, the integrity of a “"Code 39”" symbol is checked
to ensure that it complies with specified algorithms.
If “"Check Char”" is set to Validate and Transmit, the check character is validated and trans-
mitted with the data.
Setting this parameter to None disables this function.
Concatenation
“"Codabar”" supports symbol concatenation. When you enable Concatenation, the imager
looks for a Codabar symbol with a “"D”" start character that is adjacent to a symbol with a
“"D”" stop character. In this case, the two messages are concatenated into one with the “"D”"
characters omitted.
Minimum And Maximum Length
The length of a code refers to the number of characters (i.e., human readable characters), in-
cluding check digit(s). Double-tapping on these parameters displays a screen in which you
can set the minimum and maximum allowable code lengths –– 2 to 60.
Length Restriction
Refer to “"Length Restriction”" on page D-8 for details.
Add/Remove Data
Refer to “"Add/Remove Data”" on page D-9 for details.
