6.3 Field Bus connections
The TRX and RX 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 host computer or
controller!
Each device (TRX PCB and RX PCB) has a unique address. This address is factory set
and cannot be changed. A PC/laptop enables local maintenance of the TRX and RX
boards by using the Device Explorer software.
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,
which enables service and data retrieval from any remote location over the Internet.
6.3.1 Bus connections with laptop
Figure 6 shows the Field Bus structure between the various antennas.
Connecting the Field Bus to a laptop (through an Access Point), allows on-site
maintenance through the Device Explorer software.
See chapter 0 for further information on how to use the Device Explorer software.
