The antenna constantly attempts to read a fixed code. Only data that changes is
transmitted via the interface; i.e. the antenna transfers data as soon as it reads
a new data carrier or as soon as it reads a data carrier when there was previously no
data carrier in the detection area.
The status ‘05h’ (read command) is output as soon as the data carrier leaves the
detection area.
The fixed code length which is output depends on the data carrier type.
