9.7. [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 continued with RF ON. After RF OFF, the reader accepts every Host command and
the RF communication is handled over the last selected antenna. For selecting a specific antenna
without continuing the Auto Read Mode, the option flag HM must be set.

Maintain Host Mode (applicable only for Auto Read Mode)
b0: Auto Read Mode is continued, if Antenna Output is greater than zero
b1: Host Mode is maintained and Antenna Output is selected, if greater than zero
NOTE:
In the case of sending RF output ON/OFF with antenna output = b000 the Reader sends a
command to reset the persistence flags of the Transponder. This command is sent on the
antenna port which was active before the RF output ON/OFF command is sent to the Read-
er.
Switching of antenna is also possible in Scan-Mode, if multiplexer is disable.
