8.3.3 Frequency SetupPreferred channelThis value defines the preferred channel number before the reader uses another channel.In a multi-reader environment (EU only), use different channels for the readers. Use the“Preferred channel” parameter to make this setting. Select the greatest possible separation!Channel maskThis mask defines the channels to be used by the readers. Each activated checkboxenables use of the appropriate channel (for further information, see also the sectionFehler: Referenz nicht gefunden “Fehler: Referenz nicht gefunden”).Recommendation for configuration of UHF readers (EU only):If several readers are installed close together (e.g. entry and exit lanes), then channel pairsshould be set up for them, for example, channels 4 and 10, and channels 7 and 13.8.3.4 FrequenciesETSI 302 208 v1.2Channel No. Frequency E.R.P.4 865.7 MHz ≤ 2.00 W7 866.3 MHz ≤ 2.00 W10 866.9 MHz ≤ 2.00 W13 867.5 MHz ≤ 2.00 WFCC Part 15 (US)Channel No. Frequency E.I.R.P.1 902.75 MHz ≤ 4.00 W2 903.25 MHz ≤ 4.00 W3 903.75 MHz ≤ 4.00 W4 904.25 MHz ≤ 4.00 W... ... ...47 925.75 MHz ≤ 4.00 W48 926.25 MHz ≤ 4.00 W49 926.75 MHz ≤ 4.00 W50 927.25 MHz ≤ 4.00 W20 Zulassung_wi_en_ts_tsu-200_pro_v140205_te_bf
