Check Digit Test
For printed bar codes with an integrated check digit in the useful characters (last position before stop character), the check digit
increases error detection and therefore reading reliability. With a “yes” response, the decoder activates a routine to compare the
printed check digit with the check digit being calculated. The decoder then outputs the bar code data with the error status as fol-
lows: If the check digit test is successful, ST=0 (good read); if the check digit test is not successful, ST=1 (wrong check digit).
The error status is output only if the error status value is activated as part of the data string. If the user responds here with a “no,”
no check digit test will be carried out.
Transmit Check Digit
A “yes” allows the check digit to be transmitted to the host device. With a “no” response, the check digit is not transmitted.
Note: The CLV automatically truncates the last digit of the data if “no” to transmit check digit is selected.
Transmit Leading Zero
Individual characters in the code overlap so that digits can be represented in pairs only. If the code is made up of an odd digit
sequence (useful characters), it is filled out with a leading zero. With a “yes” response, the zero is included in the output. With a
“no” response, the zero is suppressed.
EAN
(European Article Numbering)
A numerical code with the following character set: 10 digits (0 to 9 per bar code character set), one edge character, one dividing
character.
Figure 3-7 EAN (European Article Numbering)
13-Digit
Code length of 13 digits.
8-Digit
Code length of 8 digits.
With Add-on
(none/2 digit/5-digit/both)
The add-on is an additional bar code of two or five digits that follows the 8 or 13 digits of the EAN. Selectable commands are:
none
=Add-on is not evaluated
2-digit
=Evaluate and output 2-digit add-on
5-digit
=Evaluate and output 5-digit add-on
both
=Evaluate and output 2-digit AND 5-digit add-on
