Check Digit Verification

A check digit is optional for Code 39 and can be added as the last digit. It is a calculated value used to verify the integrity of
the data. By default, check digit verification is disabled.

Disable: The scanner transmits Code 39 barcodes as is.

Do Not Transmit Check Digit After Verification: The scanner checks the integrity of all Code 39 barcodes to verify
that the data complies with the check digit algorithm. Barcodes passing the check will be transmitted except the last
digit, whereas those failing it will not be transmitted.

Transmit Check Digit After Verification: The scanner checks the integrity of all Code 39 barcodes to verify that the
data complies with the check digit algorithm. Barcodes passing the check will be transmitted, whereas those failing it
will not be transmitted.
**【Disable】
【Do Not Transmit Check Digit After Verification】
Note: If the Do Not Transmit Check Digit After Verification option is enabled, Code 39 barcodes with a length that is
less than the configured minimum length after having the check digit excluded will not be decoded. (For example, when the
Do Not Transmit Check Digit After Verification option is enabled and the minimum length is set to 4, Code 39 barcodes
with a total length of 4 characters including the check digit cannot be read.)
