Appendix E

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,

a29934567a 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.
