Standard Codabar: The standard Codabar bar code has 16 data characters, including the digits 0 through 9, plus the $ – + . / and :
symbols. There are four types of start and stop symbols, represented as:
A, a, T, or t;
B, b, N, or n
C, c, or * (twice)
D, d, E, or e.
Codabar ABC format: The Codabar ABC code consists of two bar codes, which are decoded in one cycle (single scan).
For the first bar code, there are three types of start symbols: A, a, T, or t/B, b, N, or n/C, c, or * (twice)
and one type of stop symbol: D, d, E, or e.
For the second bar code, there is one type of start symbol: D, d, E, or e
and three types of stop symbols: A, a, T, or t/B, b, N, or n/C, c, or * (twice).
Codabar CLSI format: This is a fixed 14 character Codabar code which must follow the pre-defined format to transmit to
the host computer. The start and stop symbols are the same as the standard format.
Codabar CX format: The Codabar CX code consists of two bar codes, which are decoded in one cycle (single scan).
For the first bar code, there are three types of start symbols: A, a, T, or t/B, b, N, or n/C, c, or * (twice)
and one type of stop symbol: C, c, or * (twice).
For the second bar code, there is one type of start symbol: B, b, N, or n
and three types of stop symbols: A, a, T, or t/B, b, N, or n/C, c, or * (twice).
Start/Stop Symbol Transmission: Start/Stop characters identify the leading and trailing ends of the bar code.
