Protocols for controlling the reader
7.6 [0x6A] RF Output ON/OFF
7.6
[0x6A] RF Output ON/OFF
The command "RF ON/OFF" switches the RF field of the antenna of the reader ON and
OFF.
In the automatic read mode of the reader (Scan Mode, Buffered Read Mode), RF
communication can be interrupted with "RF OFF" and continued with "RF ON". After "RF
OFF", the reader accepts every host command and RF communication is via the last
selected antenna. To select a specific antenna without continuing the automatic read mode,
the option flag HM must be set.
