Hello,

what communication protocol need that Honey. Scanner? This is important. You can set only ASCII or 3964 protocol on your card so check that required protocol. If it's barcode scanner, it can use ASCII protocol so set this protocol to your card and use only <Receive> instruction for collect data from Scanner.
