CHECK CHARACTER

No check character means the device will read and transmit all barcodes with or without check
characters. (When barcode with check character is scanned at this time, check character is
transmitted together.)
When "Checksum character" is set to "Enable Without Check Character Transmission", the barcode
scanning device will check the barcode according to the last bit of data, if the check passes, the
normal data except the last check character will be transmitted, and if the check fails, the barcode
content will not be sent. The barcode content will not be sent if the verification passes.
When "Check Character" is set to "Enable With Check Character Transmission", the barcode
scanning equipment will check the last bit of the barcode data, and if the check passes, the check
character will be transmitted as the last bit of the normal data, and if the check fails, the barcode
content will not be sent. The content of the barcode will not be sent if the verification is passed.
