Concatenation of Code 128
When Code128 data’s leading is FNC2 character, concatenate or not can be set.
Reading the barcode that contains FNC2 character in leading of Code128 data, concatenate the data
by omitting the leading FNC2.
When reading the barcode that does not contains FNC2 character in leading of Code128, it
concatenates the data to the end of data that is buffering to the scanner, and send entire buffer.
The reading time is updated every time 1 label is read, but if the reading is not completed within the
reading time, the buffered data will be discarded.
The maximum number of character that can be concatenated at a time is 400 characters.
