AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules The following steps are used: 1. Access DevConfig to configure the AVW200 for SDI-12 communications. Go to the Deployment/Measurement tab in DevConfig and enter the SDI-12 Address, multiplexer type, begin frequency, end frequency, and excitation (see Section 5.1, Connecting to DevConfig, and Section 5.2.2, Measurement). 2. Use a CABLE4CBL-L cable to connect the AVW200 to the multiplexers (see FIGURE 4-5). NOTE SDI-12 uses the CLK and RESET on the multiplexer instead of the CLK and RESET address on the AVW200. 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 a CABLE4CBL-L cable to connect the multiplexers to the datalogger (see FIGURE 4-6). 5. Use a CABLE3CBL-L cable to connect the C1 terminal on the AVW200 to a control port and ground on the datalogger. 6. 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. Read more! You can find power and ground connection information in Section 4.2, and datalogger connection information in Section 4.3. 7. Program the datalogger. Our CRBasic dataloggers use the SDI12Recorder instruction and Edlog dataloggers (i.e., CR10X, CR23X) use Instruction 105. The SDI12Recorder instruction should only be run in the sequential mode. Read more! The SDI12Recorder instruction is discussed in Section 6.2. An example CRBasic program is provided in Section 7.5, and an example Edlog program is provided in Appendix G. 4. Connections 4.1 Sensor Wiring (no multiplexers) Up to two vibrating wire sensors can be directly connected to the AVW200 (see FIGURE 4-1). Sensor cabling is sold as a part of the sensor (refer to the sensor manual for wire colors). Cable options for connecting the AVW200 to the datalogger are listed in TABLE 4-1. 18

AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules
The following steps are used:
1.
Access DevConfig to configure the AVW200 for SDI-12 communications.
Go to the Deployment/Measurement tab in DevConfig and enter the
SDI-12 Address, multiplexer type, begin frequency, end frequency, and
excitation (see Section 5.1,
Connecting to DevConfig
, and Section 5.2.2,
Measurement
).
2.
Use a CABLE4CBL-L cable to connect the AVW200 to the multiplexers
(see FIGURE 4-5).
SDI-12 uses the CLK and RESET on the multiplexer instead of
the CLK and RESET address on the AVW200.
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 a CABLE4CBL-L cable to connect the multiplexers to the datalogger
(see FIGURE 4-6).
5.
Use a CABLE3CBL-L cable to connect the C1 terminal on the AVW200
to a control port and ground on the datalogger.
6.
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.
Read more! You can find power and ground connection information in
Section 4.2, and datalogger connection information in Section 4.3.
7.
Program the datalogger.
Our CRBasic dataloggers use the SDI12Recorder
instruction and Edlog dataloggers (i.e., CR10X, CR23X) use Instruction
105.
The SDI12Recorder instruction should only be run in the sequential
mode.
Read more! The SDI12Recorder instruction is discussed in Section 6.2.
An example CRBasic program is provided in Section 7.5, and an example
Edlog program is provided in Appendix G.

Up to two vibrating wire sensors can be directly connected to the AVW200
(see FIGURE 4-1).
Sensor cabling is sold as a part of the sensor (refer to the
sensor manual for wire colors). Cable options for connecting the AVW200 to
the datalogger are listed in TABLE 4-1.
