Setup help of the readers of the second generation

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 turned on, in contrast to generation 1 in which the antenna is turned
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.
Meaning of the LED operating display in the "Setup" mode
The operational statuses of the reader are displayed by two LEDs. The LEDs can adopt the
colors white green, red, yellow or blue and the statuses off , on , flashing .

Display elements
LED Meaning
The reader is turned off.
The reader is turned on and is searching for transponders.
The reader is in the "Setup" mode, in the "Search for transponders" status and
has not yet received a "RESET" command and is not ready.
/ There is transponder in the antenna field.
The reader is in the "Setup" mode, in the status "Show quality", has not yet re-
ceived a "RESET" command and is not ready.
Depending on the quality of the communication, the LED flickers or is lit perma-
nently.
