CHECK CHARACTER

No check character means that the device will read and transmit all barcodes whether there is a
check character or not. (At this time, when scanning the barcode with check characters, the check
characters are transmitted together.)
When "Check Character" is set to "Enable without check character transmission", the device will
check according to the last digit data of the barcode. If the check passes, normal data except the
last check character will be transmitted. If the check fails, the barcode content will not be sent.
When "Check Character" is set to "Enable with check character transmission", the device will check
according to the last digit data of the barcode. If the check passes, the check character will be
transmitted as the last digit of normal data. If the check fails, the barcode content will not be sent.
