Setup aid for the reader
After turning on the reader (connection to the power supply) and the following startup phase,
the reader automatically changes to the "Setup" mode. During this the antenna (reader-internal
or external) is switched on, in contrast to the 1st generation in which the antenna is switched
on by a RESET.
In this status "search for transponders" the reader scans the antenna field for transponders with
all air interface protocols (RF300, ISO 15693, ISO 14443). If a transponder is recognized in the
antenna field of the reader only the HF protocol of the recognized transponder type is used and
there is a change in the status to "Show quality". In this status you obtain direct feedback about
the quality of the communication with the transponder via the LED. Depending on the
environment (metal, interference) or the field coupling with the transponder (size of the
transponder antenna) as well as the individual field geometry (shape of the main and side lobe)
of the reader, communication can be very good (permanent light) or good (flickering) at certain
locations in the antenna field. These factors give users the option of finding the optimal area in
the specific installation situation or in a combination. If no transponder is recognized for a longer
period of time, the reader changes back to the "Search for transponders" status.
When a "RESET" command is received, the reader changes back to the normal operation as
known from the RF300.
