Descriptions
Decoded Data in FSC packet format
Decode Data is considered as an unexpected event since the decoded data will be sent to the host
whenever the scanner scanned a barcode, either accidentally or intentionally. The decoded data is
sent in two types of format, either packed or unpacked. If packed data is selected, the scanner will
send a packed Decode Data message rather than a Raw Data message to the host after a
successful decode.
