Appendix I.
Using MD485 Multidrop Modems with AVW200 Interfaces
I.2 Connections
The point-to-point configuration is the simplest MD485-to-AVW200 network.
In this configuration, two MD485s are required (see FIGURE I-2).
The point-to-multipoint configuration uses several AVW200s.
In this
configuration, you need one MD485 to connect with the datalogger and another
MD485 for each AVW200 in the network (see FIGURE I-3).
