“Change parameters” frame
All parameters can be changed using this frame, including serial interface parameters.
Please note:
●
Acknowledgement from the reader is sent with the old settings
●
Subsequent scan data are sent with the new settings
●
The parameters can be stored in the reader either retentively or non-retentively:
–
In a retentive parameter assignment, the transmitted data are still available after the
reader is powered up again.
–
In non-retentive parameter assignment, the data are only changed for current
operation. The previous parameters are used the next time the reader is powered up.
After the parameters are accepted and the acknowledgement is sent, the reader returns
automatically to scan mode.
