Draft Version 02.06.2010 - Siemens SIMATIC RF600 System Manual

4.7 Operation of RF600 readers according to EN 302208 V1.2.1 and EN 302208 V1.1.1
Note
If an RF660R reader with firmware version V1.3 is to replace a reader commissioned before
1 January 2010, the new reader can also use a firmware version older than V1.3. The
downgrade is described in the "RF660R Configuration Software" configuration manual.
Note
If possible, upgrade all older RF660R readers to the new firmware V1.3.
4.7.2 Disturbances when operating readers according to ETSI EN V1.1.1 and V1.2.1 in
mixed mode
If RF600 readers in the ETSI band (EU, EFTA & Turkey) are operated according to
EN 302 208 V1.1.1 (firmware V1.2) and at the same time to EN 302 208 V1.2.1 (Firmware
V1.3) in close proximity to each other (up to 20 m), these readers might interfere with each
other.
Reasons for interference
The following reasons may cause the interference:
● Only four transmission channels (865.7; 866.3; 866.9; 867.5 MHz) are now available
according to the latest ETSI standard.
● Deactivation of Listen Before Talking (LBT)
● When operating readers in mixed mode according to the old ETSI standard
(EN 302 208 V1.1.1) and the new ETSI standard (EN 302 208 V1.2.1), the transmission
and receive channels may interfere with each other. Tag reading might thus be blocked.
(See Chapter Possible causes of error (Page 67))
RF620R and RF630R
The RF620R (ETSI) and RF630R (ETSI) readers support both ETSI standards
EN 302 208 V1.1.1 and V1.2.1 (max. 4 channels without LBT). As of January 2010, these
readers must be operated using the 4-channel plan and without LBT.
RF660R
RF660R readers V1.2 or earlier firmware versions exclusively use a radio profile according to
EN 302 208 V 1.1.1 (max. 15 channels with LBT).
RF660R readers V1.3 or later firmware versions exclusively use a radio profile according to
EN 302 208 V1.2.1(max. 4 channels without LBT).
