7.7. [0x6A] RF Output ON/OFF
The command RF ON/OFF switches the RF field of the Reader antenna ON and OFF.
If the reader works in Auto Read Mode
the RF communication can be interrupted by transmitting RF OFF and contin-
ued with RF ON. After RF OFF, the reader accepts every Host command and the RF communication is handled on the
last selected antenna. For selecting a specific antenna without continuing the Auto Read Mode, the option flag HM must
be set.
