Address : 023E (bank 2, register 3E)

Size : 3 bytes

Default : 000000

Content

Byte 0 : Min. polling interval (10th of second)

Use this parameter to slow down the reader (this is the first step to reduce average power consumption).

Remark : If set to 00 (default), the reader operates at maximum speed.

Byte 1 : Min. time before restarting polling after card removal (10th of second)

Use this parameter if the host system is unable to handle a new card immediately after the previous one.

Remark : If set to 00 (default), the reader doesn't add a pause after a card removal.

Byte 2 : Shutdown RF if a card remains in the field during a long time (seconds)

Use this parameter to prevent a card from overheating (and maybe being destroyed) if it stays in the RF field for a long time.

Remark : If set to 00 (default), the reader never stops the RF field while a card is present.
