Codabar
Codabar is widely used in libraries, blood banks, the
cotton industry and transportation industries. Its'
character set consists of numbers 0 through 9, and
punctuation characters + . - / : and $. Symbols a, b, c,
d, t, n, * and e are used as start and stop characters.
Characters are constructed of four bars and three spaces.
Codabar is a numeric-only code, but different combinations of start and stop
characters can be used to identify different types of labels. Codabar's variable data
length and extremely low error rate make for a versatile bar code.
Codabar start/stop transmission
The Codabar section on the WDP Setup Menu lets you determine whether
Codabar start/stop characters are transmitted or not. If you are varying start/stop
characters with different types of labels, you'll want to "Enable Stop/Start character
Transmission". Start/stop character transmission can also be helpful if you want
your program to differentiate between data coming from the WDP reader and data
coming from the keyboard. If neither of these situations apply, you'll probably
want to disable it.
