5.3 Field Bus connections
The RFM antennas are interconnected through the Field Bus by using preferably FTP
cables, because FTP has an advantage to eliminate noise because of the extra shielding.
The Cross Point Field Bus requires the devices to be connected in a
“daisy chain” connection. A “star” network is not allowed and will result
in poor communication between the devices and the CrossCONNECT
Access Point!
When the Field Bus is connected to the Access Point and the Access Point is connected
to a Local Area Network (LAN), local servicing and data retrieval is possible. When an
internet connection is available, the Access Point can also be connected to the Internet.
This will enable remote service and data retrieval.
5.3.1 Bus connections with laptop
Figure 2 shows the Field Bus structure between the various antennas.
All devices are connected to an Access Point, which is connected by Ethernet connection
to a laptop or to the local network (LAN) of the store. This enables on-site maintenance
and remote service using Cross Point Device Explorer software.
See chapter 7 for further information on how to use the Device Explorer software.
