Setting Rf640A Parameters For Rf680R/Rf685R - Siemens Simatic RF600 System Manual

Operation in the USA, Canada
Note
Limitation of the radiated power to 4000 mW EIRP (36 dBm EIRP)
To meet the FCC and IC requirements, the radiated power may not exceed 4000 mW EIRP
(36 dBm EIRP). Therefore the system must satisfy the following relation:
• Conducted power P dBm of the RF600 reader (< 30 dBm)
• Antenna gain G
• Cable loss a
P(dBm) ≤ 30 dBm - (G

Setting RF640A parameters for RF680R/RF685R

Operation within the EU according to DIN EN 302208 V1.4.1
Note
Limitation of the radiated power according to DIN EN 302208 V1.4.1
RF600 systems that are put into operation within the EU, EFTA, or Turkey (ETSI) can be
operated with an RF640A antenna with a maximum radiated power of 2000 mW ERP (or 33
dBm ERP, 3250 mW EIRP, 35 dBm EIRP).
By setting the radiated power of up to 1300 mW ERP (or 31.15 dBm ERP, 2140 mW EIRP,
33.3 dBm EIRP), an RF640A antenna gain of 4 dBi (7 dBic) and taking into account the
cable loss associated with the antenna cable (see table (Page 276)), the radiated power of
the reader is correctly configured and the radiated power at the antenna is not exceeded.
Operation in China
By setting a max. radiated power of 2000 mW ERP (or 33 dBm ERP, 2140 mW EIRP,
33.3 dBm EIRP), an RF640A antenna gain of 4.3 dBi (7.3 dBic) and taking into account the
cable loss associated with the antenna cable (see table (Page 276)), the radiated power of
the reader is correctly configured.
