4.5.2 Datalogger Controlling the Multiplexer

When using SDI-12, the datalogger must control the multiplexer. Use the

CABLE4CBL-L cable to connect the AVW200 to the multiplexer if the

vibrating wire sensors contain a thermistor (see FIGURE 4-5). Use the

CABLE3CBL-L or equivalent cable if the vibrating wire sensors do not

contain a thermistor. The CLK and RESET lines on the multiplexer are used

instead of the CLK and RESET lines on the AVW200.
