The programmer’s guide is divided into two parts:
The first part pertains to the Generic Reader Interface which covers the API and Usage supported by the reader via the LLRP Interface. This interface is used for routine operations like Reading Tags (Inventory), Programming Tags (Tag Access Operations like Read, Write, Lock, Kill) and configuring the Reader.
The second part pertains to the Reader Management Interface which is used for managing the Reader (Software Update, Reset, Using Config Files, etc).
RFID API2 APIs are backward compatible on LLRP based RFID Readers. API2 Applications can use the existing API2 interface available in Symbol.RFID2.Host class library.
However, in case of requirement for multiple enhanced features which are not supported by API2, it is preferable to write a separate RFID API3 Application with the new class library Symbol.RFID3.
