Industry Canada Notice
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication.
Transmitter power and antenna information for antennas with a gain less than 6 dBi:
This device has been designed to operate with the SIMATIC RF615A antenna 902-928, the
SIMATIC RF622A antenna 902-928, the SIMATIC RF650A antenna 902-928, the SIMATIC
RF662A antenna 902-928 as well as the SIMATIC RF680A antenna listed below, and having
a maximum gain of 5,5 dBi. Arbitrary transmission power settings in combination with other
antennas or antennas having a gain greater than 5,5 dBi are strictly prohibited for use with
this device.
The required antenna impedance is 50 Ohms.
Transmitter power and antenna information for antennas with a gain greater 6 dBi:
This device requires professional installation. Antennas with a gain greater 6 dBi may be used
provided the system does not exceed the radiation power of 4000 mW E.I.R.P. This device
has been designed to operate with the SIMATIC RF642A antenna 902-928 exceeding the
maximum gain of 5,5 dBi under the restriction that the RF power at the input of the antenna
must be set to meet the following relation: RF power (dBm) ≤ 30 dBm – (antenna gain (dBi) –
6 dBi) Other antennas or system configurations for antennas having a gain greater than 6 dBi
are strictly prohibited for use with this device. The required antenna impedance is 50 Ohms.

Merkmale
Der SIMATIC RF685R ist ein stationärer Reader im UHF-Frequenzbereich mit integrierter
Antenne. Über einen RP-TNC-Anschluss kann zusätzlich eine externe UHF-RFID-Antenne
angeschlossen werden.
Die maximal abgegebene Sendeleistung beträgt 2000 mW am externen Reader-Ausgang,
die Strahlungsleistung der internen Antenne beträgt ebenfalls 2000 mW ERP/EIRP. Bei
Verwendung entsprechender Antennen und Antennenkabel wird eine Strahlungsleistung bis
zu 2000 mW ERP / 4000 mW EIRP erzielt. Die Schnittstellen (Ethernet, Spannungsversorgung,
DI/DO-Schnittstelle) befinden sich an der unteren Stirnseite. Über diese Schnittstellen
kann der Reader an die Spannungsversorgung und an einen PC oder eine Steuerung zur
Parametrierung angeschlossen werden.
