AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules 
4.  Create a CRBasic program that includes an AVW200() instruction for each 
of the sensors.   
Check the manufacturer’s specification for the sensors frequency 
and excitation range before picking the begin/end frequencies 
and excitation voltage.  
NOTE 
For example, the following AVW200() instructions can be used to 
measure two sensors:  
 AVW200(Result,Com1,200,200,Dst(1,1),1,1,1,1000,3500,2,_60HZ,1,0) 
 AVW200(Result,Com1,200,200,Dst(2,1),2,1,1,1000,3500,2,_60HZ,1,0) 
 Where,  
    AVW200 connects to datalogger control ports 1 & 2 via 17855 cable  
(option Com1)  
    Begin Frequency = 1000 
    End frequency = 3500 
    Excitation voltage = 12 V peak to peak (option 2)

parameters is provided in Section 6.1.  A complete example program that 
measures two vibrating wire sensors (no multiplexer) is included in 
Section 7.1.1.

For this example configuration, the sensor(s) are attached directly to the 
AVW206.  The AVW206 interface transmits the data to an RF401 spread 
spectrum radio that is connected to the datalogger.    
At the AVW206 site, do the following steps: 
1.  Configure the AVW206 for RF communications as described in Sections 
5.1 and 5.2.1.
