For this example configuration, vibrating wire sensors are attached to
multiplexers, which are controlled by the AVW200.
The AVW200 is
connected directly with the datalogger.
The following steps are used:
1.
If you are not using the default multiplexer, go to the
Deployment/Measurement tab in DevConfig and select the multiplexer
you are using (Section 5.1,
Connecting to DevConfig
, and Section 5.2.1,
Communications
).
The default multiplexer for the AVW200 is the
AM16/32A.
2.
Attach the multiplexers to the AVW200 as shown in FIGURE 4-4.
3.
Connect the sensors to the multiplexers.
Read more! Information about connecting the vibrating wire sensors to
the multiplexer is provided in the AM16/32B manual.
4.
Use the 17855 cable to attach the AVW200 to control port pairs on the
datalogger, or use the 18663 Null Modem cable to attach the AVW200 to
the RS-232 port on the datalogger.
5.
Connect one end of the 19246 power cable to the 12V and G terminals on
the AVW200 and the other end to the 12V and G terminals on the
datalogger or external power supply.

You can find power and ground connection information in
Section 4.2 and datalogger connection information in Section 4.3.
6.
Create a CRBasic program that includes the AVW200() instruction for
each of the multiplexers that the AVW200 will control.
