Dense Reader Mode (DRM)
The readers can also interfere with each other (secondary fields), if the channels (Reader
TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a
reader channel, we recommend that the Dense Reader Mode (DRM) is used.
Note
Protective cap
If you use the internal antenna of the reader, we recommend that you close the external,
unused antenna connector on the reader using the supplied protective cap.
Antenna diagram for RF640R (ETSI)
The following radiation diagrams show the directional characteristics of the internal antenna
of the RF640R (ETSI) reader. For the spatial presentation of the directional characteristics,
the vertical plane (Azimuth section) as well as the horizontal plane (elevation section) must
be considered. This results in a spatial image of the directional radiation pattern of the
antenna with its main and auxiliary fields.
