AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules
1.3.2 Computer
1.3.2.1 Device Configuration Utility
The Device Configuration (DevConfig) Utility supports AVW200
configuration, operating system download, and vibrating wire spectrum
analysis troubleshooting. To use DevConfig, the AVW200 must be connected
to a PC and a power source. DevConfig is bundled in Campbell Scientific’s
datalogger support software and can also be acquired, at no cost, from
Campbell Scientific’s website. DevConfig 1.10 or greater is required.
Read more! DevConfig is described in detail in Section 5.
1.3.2.2 LoggerNet
LoggerNet supports datalogger programming, accesses the status and public
tables, and displays network routing. Please ensure that the AVW200 CRBasic
instruction is included. If using LoggerNet 3.4.1 or lower, the user needs to
download the most recent OS for the datalogger. This installation installs the
required CRBasic files on the user’s computer so that the AVW200 instruction
shows up in the editor.
Read more! Programming information is provided in Section 6. Also,
refer to the LoggerNet manual and help.
1.3.2.3 Terminal Commands
You can monitor the AVW200 by entering terminal commands in the terminal
emulator of DevConfig or LoggerNet. HyperTerminal or ProComm can also
be used. The AVW200 needs to be connected to a computer with a standard
RS-232 cable (CSI model 10873).
Read more! Terminal Mode Commands are discussed in Section 5.6.
1.4 Use with Multiplexers
For the AVW200 interfaces, the AM16/32B multiplexer is recommended over
its predecessors (i.e., AM16/32, AM16/32A). The AM16/32B has a clocking
mode that can use relay addressing to go directly to a specific channel—
reducing power consumption and wear on the relay switches.
Up to 32 vibrating wire sensors without thermistors or 16 vibrating wire
sensors with thermistors can be connected to one multiplexer. Two
multiplexers can be connected to one AVW200. Using a direct RS-232
connection, up to four AVW200 interfaces can be connected to one CR1000 or
CR3000; up to two AVW200 interfaces can be connected to one CR800 or
CR850. This allows up to 256 vibrating wire sensors (128 with temperature) to
be measured by one CR1000 or CR3000 (see FIGURE 1-1) or 128 vibrating
wire sensors (64 with temperature) to be measured with one CR800 or CR850.
FIGURE 1-2 and FIGURE 1-3 indicate the number of interfaces that can be
connected to one datalogger when using wireless interfaces or the SDI-12
protocol.

wiring information in 4.5, programming information in Section 6, and
programming examples in Section 7.
