2.9. Protocol Debug Tab
This tab is used to debug the EPC protocol using graphics. Details of communication
required to execute one EPC operations Inventory Round, Read, and Write are shown.
Rounds with slots and all EPC commands of communication are shown in color codes.
Green color is used to show normal operation, yellow is used to show slots with no
response and red is used to show unexpected slot termination. The meaning of the
interrupt or error code returned by AS3990 is shown in the red area. Rounds are repeated
at least twice to find all the transponders. When reader finds a round with all empty slots
it assumes that all tags are inventoried. This is marked in magenta at the end of the line.
