We created a barcode to work with OPOS utility, but when we scan PDF 417 barcode, it added 2 characters "QC" in the beginning. After creating ADF rule for PDF 417 in the 123Scan utility, still getting "Q". The ADF rule is below. Scanner is connected with POS with RS-232 Interface. What other rule can add to get rid of "Q" character when scanning in the OPOS utility.
I tested the PDF417 barcode in hyperterminal and not getting any character in the beginning which is confirm that barcode is not program with the characters.
