Calculation of the code length of a bar code

The code length of a bar code corresponds to the number of used characters in the printing

image including the check digits (if they exist). The fixed code length can be specified in the

CLP Setup.

The code length can be determined by counting the bars and gaps if the code type of a bar

code is known. The respective equation for calculation is shown in

Table 10-2

1. Count the bars and possibly gaps as specified in

Table

. Also count the start and

stop characters.

2. Calculate the code length in accordance with the equation specified in the table.

3. Carry out the input in the CLP Setup as specified in Column 4 of

Table 10-2

.

1) Check digit optional for Code 39, 2/5 Interleaved, Codabar.

Check digit always integrated in the bar code print at EAN, UPC, Code 128, EAN 128 in accordance with specification
(is suppressed automatically at the output of the read result of the CLP 100)

2) With few exceptions each printed character corresponds to an ASCII character which has to be decoded.

In the case of Code 39 extended, Code 128 and EAN 128 the number of characters in the data string of the CLP 100 can exceed the number of characters in the printing
image because it consists of several character sets.
