By choosing an entry in the drop down box Parameter set the respective set gets activated in the reader
device. Changes made on the respective parameter settings have to be saved to the reader device by
choosing Save configuration. By choosing Reload configuration the made change on the GUI are
discarded and overwritten by the settings stored in the reader.
When changing the transmission channels are only available in the “EU” version of the reader.
Note: When changing the transmission power you need to stick to the applicable national regulations. To
operate the reader in accordance with the related national standards, the antenna gain and the cable
attenuation must be taken into account in the transmission power setting. In no circumstances is it allowed to
exceed the permitted transmission power. Failure to observe this instruction can result in non-compliant
operation of the reader rendering void the unit's type approval.
The radiated power is limited in Europe in accordance with ETSI 302208 to 2W ERP. In the FCC region, the
power is limited to max. 1 W connected RF power with an antenna gain of 6 dBi. If the antenna gain is
greater than 6 dBi, the RF power must be reduced accordingly. While the European standard refers to a half-
wave dipole (ERP), FCC part 15 refers to an isotropic radiator (EIRP).
To set the transmission power, the length-dependent cable attenuation and the antenna gain must be
included in the calculation of the transmission power. An example for the calculation of the transmission
power for Europe and FCC is given below:
