Time response of [0x01] inventory and ISO 15693 transponders
All times relate to the following parameters: ISO15693 MODE = 0x0B (see "CFG4:
Transponder parameters (Page 28)")
●
AFI deactivated
●
16 time slots
The modulation and the sub-carrier have only a negligible influence on the reaction time.
The following diagrams show average values for the time response depending on the
number of transponders. With certain UIDs, the times may be longer or shorter than shown
below.
The time response is measured including the communication time at 38.4 kBd. Another baud
rate increases the times slightly but the inventory time is mainly obtained based on the
anticollision which is why you can disregard the communication time.

Execution time
b + c Communication time
The setting of the time slots should be made depending on the expected number of
transponders in the antenna field at one time to ensure the fastest possible processing:
●
up to 30 transponders: 1 time slot
●
as of to 30 transponders: 16 time slots
