Codabar Specifications

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 TriCoder Setup lets you determine whether Codabar start/stop characters are tra nsmitted 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 t he TriCoder and data
coming from the keyboard. If neither of these situations apply, you'll probably want to disable it.
