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 RF Laser 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 RF Laser Reader and data coming from the
keyboard. If neither situation applies, you'll probably want to disable it.
