RF300 system planning
4.2 Field data for transponders, readers and antennas
Minimum distance from transponder to transponder
Minimum distance from reader to reader
RF310R to RF310R
Minimum distance from antenna to antenna
NOTICE
Adherence to the values specified in the "Minimum distance from reader to reader" table is
essential. The inductive fields may be affected if the distance is smaller. In this case, the
data transfer time would increase unpredictably or a command would be aborted with an
error.
If the specified minimum distance cannot be complied with due to the physical configuration,
the SET-ANT command can be used to activate and deactivate the HF field of the reader.
The application software must be used to ensure that only one reader is active (antenna is
switched on) at a time.
