Check Character Verification - Newland NLS-HR42 User Manual

Check Character Verification

Check characters are optional for Code 11 and can be added as the last one or two characters, which are calculated values
used to verify the integrity of the data.
If the Disable option is enabled, the scanner transmits Code 11 barcodes as is.

If you select a check character algorithm and the Do Not Transmit Check Character option, Code 11
barcodes with a length that is less than the configured minimum length after having the check character(s)
excluded will not be decoded. (For example, when the One Check Character, MOD11 and Do Not
Transmit Check Character options are enabled and the minimum length is set to 4, Code 11 barcodes
with a total length of 4 characters including the check character cannot be read.)
