4.3 Installation guidelines

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 from reader to reader" table,
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.
Adherence to the values specified in the "Minimum distance from reader to reader" 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.

Overview

The transponder and reader complete with their antennas are inductive devices. Any type of
metal in the vicinity of these devices affects their functionality. Some points need to be
considered during planning and installation if the values described in the "Field data
(Page 35)" section are to retain their validity:
● Minimum spacing between two readers or their antennas
● Minimum distance between two adjacent data memories
● Metal-free area for flush-mounting of readers or their antennas and transponders in metal
● Mounting of multiple readers or their antennas on metal frames or racks
The following sections describe the impact on the operation of the RFID system when
mounted in the vicinity of metal.
