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 Wireless Reader 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 Wireless Reader and data coming from the

keyboard. If neither situation applies, you'll probably want to disable it.
