Minimum distance from reader to reader

RF210R to
RF210R
≥ 60 mm
All values are in mm
Note
Effect on inductive fields by not maintaining the minimum distances of the readers
If the values fall below those specified in the "minimum distance readers or antennas", there
is a risk of the function being affected by inductive fields. In this case, the data transfer time
would increase unpredictably or a command would be aborted with an error.
Keeping to the values specified in the "Minimum distance readers or antennas" table is
therefore essential.
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.
