For addenda scanning (e.g. ISBN), you need to select both the base barcode and then the addenda(s) you want to capture. For example, you would select EAN_13 and either or both the 2CHAR_ADDENDA and 5CHAR_ADDENDA options depending on what you will be scanning.
If you want to convert UPC-E scans into the UPC-A equivalent you need to select the barcode format “UPC E Expand” and any other UPC-E and UPC-A barcodes you want to scan. See screenshot below:
