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 "Check character" is set to "Enable without check character transmission", the device will
check the barcode according to the last bit of data, if the check passes, the normal data except the
last checksum character will be transmitted, and if the check fails, the barcode content will not be
sent.
