4.5 Antenna installation
4.6 Power supply
The device can be connected to an internal power supply of the system or to an
external power supply.
Once the device is connected to the power supply, the power LED lights up.
ATTENTION
Consider the required read and write ranges when installing the antenna. The
reader can only be used properly if the transponder is located within the
individual reading/writing range of the respective antenna.
If the transponder is very close to the antenna, the transponder may be
detuned by the metal of the antenna and a reading/writing is not possible. We
recommend keeping a minimum distance between transponder and antenna of
about 10 mm.
