4.4 Installation instructions
The reader module uses passive RF/ID technology, which is sensitive to RF noise sources.
Noise sources are generally of two types: radiating or conducting.
Conducted noise enters the reader via wires from the power supply or the host. Sometimes,
switching power supplies generate enough noise to cause reader malfunction, it is
recommended to use linear system power supplies.
Radiated noise is transmitted through the air. It can be caused by computer monitors or other
electrical equipment generating electromagnetic fields.
Consequently, a short distance between the reader modules themselves can cause reading
malfunctions
– for correct operation it is necessary to keep a minimum distance of 50 cm.
Various metallic constructions may have a negative influence on this distance; if there are
any doubts, it is recommended to perform a practical test before final mounting.
