Tips for installing identiCLASS readers and antennas
Installing the antennas in surroundings which have metal nearby may cause the reader to suffer
reduced performance, or not work. Setup and test the reader and antennas before enclosing
them so you know they are working, as described in
Section 5 Configuration, Setup and Testing. The following guidelines help when you integrate
the identiCLASS readers and antennas with your equipment.
reduced performance, or not work. Setup and test the reader and antennas before enclosing
them so you know they are working, as described in
Section 5 Configuration, Setup and Testing. The following guidelines help when you integrate
the identiCLASS readers and antennas with your equipment.
1. If possible, mount the antennas in an enclosure which is not made of metal, and
contains little or no metal. This is the ideal solution.
2. Keep metal as far away as possible from the antenna(s).
3. Install identiCLASS and test it in its new enclosure. If it worked when tested outside
the enclosure, but now does not work, you need either
a.
Locate the antennas further away from the metal, or
b.
Use ferrite material to cancel the effect of the metal in the enclosure.
Ideally, use a different enclosure without any metal.

4. Using ferrite material is a matter of trial and error. Ferrites are magnetically soft
ceramic materials which consist of mixed crystals, or compounds, of ferric oxide
and another bivalent metal oxide. The main characteristic of ferrites is that they are
poor electrical conductors while having a high magnetic permeability. This allows
ferrites to be used to shield the reader’s field from nearby metal.

Cables
Cables are provided to connect antennas to readers (10cm), to connect smart card adapters to
the 3300 Reader Core (15cm) and to connect the reader to the USB port.
the 3300 Reader Core (15cm) and to connect the reader to the USB port.
The ribbon cable should not be folded with a hard crease (radius defined at <
3mm) like a piece of paper more than once; for example if creased at 1mm
never unfold it.
never unfold it.
The cable performs best if placed in free space. To avoid detuning the antenna,
do not attach the cable to a metal surface. Observe capacitive couplings near
metallic surfaces: within 10mm.
metallic surfaces: within 10mm.
If a cable is damaged it must be replaced by the exact type and length item.
