Fibre Optic Ethernet Link

Typical Distributed & Synchronised NetPod 4000 Systems Application

The diagrams below shows how a typical NetPod 4000 distributed networked data acquisition system application is put together allowing for multiple instruments within junction boxes widely spaced upon a single network. The instruments are able to accept a large range of different inputs and are networked locally within a junction box to allow for easy expansion and systems maintenance. All junction box systems are further connected onto a fibre optic network back to a central data analyser PC.

Figure 15 above shows junction boxes containing NetPod 4000 instruments
deployed upon the suspension bridge at widely distributed locations

Figure 16 shows how multiple instruments within a junction box are networked together and how they systems are connected onto the fibre optic network.

Each of the NetPod 4000 instruments can have installed any combination of sensor inputs. New units can be added or old ones removed while the data acquisition operations are active simplifying systems maintenance and allowing for very simple systems expansion.

Should new channels be required simply connect a new instrumnent to the network.

Figure 17 above shows a typical fibre optic Ethernet network with the junction box instrumentation connected. Each of the junction boxes is connected
to an individual port on the Fibre optic network interface. Each of the fibre optic network interfaces are further networked together using a 100BaseT network to the data analysis PC. This type of network can be
