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 char . - / : 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
USB Laser 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 Laser Scanner and data coming from the keyboard. If neither of these situations apply, you'll probably want to disable it.
