7.3 Transponder Serial Number Related Commands
7.3.1
Continuous read mode „c‟
The reader reads and displays serial numbers continuously while one or more tags remain in the field.
This command stops as soon as any character is sent to the reader if the Noisy Environment bit is
cleared.
The reader supports different tag types at the same time. In order to increase the reading
performance, switch to single tag mode. If more than one tag shall be detected at the same time, the
MultiTag flag must be activated. The response data length mainly depends on the tag type.
