Quick Start Guides
The AVW200 can be used in many types of systems—from simple to complex.
The following quick start guides provide steps used to set up a system for some
example configurations.

For this simple configuration, the AVW200 can be used straight from the box
(i.e., settings do not need to be changed in DevConfig).
The sensor(s) are
attached directly to the AVW200.
The AVW200 is connected directly with the
datalogger via the 17855 cable or 18663 cable.
The 17855 cable terminates in
pigtails for connection to datalogger control port pairs (C1/C2…C7/C8).
The
18663 Null Modem Cable has a DB9 connector for attachment to the
datalogger’s RS-232 port.
The following steps are used to measure the sensor(s):
1.
Attach the vibrating wire sensor(s) to the AVW200 as shown in
FIGURE 4-1.
2.
Use the 17855 cable to attach the AVW200 to a control port pair on the
datalogger (i.e., C1/C2, C3/C4, C5/C6, C7/C8), or use the 18663 Null
Modem cable to attach the AVW200 to the RS-232 port on the datalogger.
3.
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 connection information in Section 4.2,
and datalogger connection information in Section 4.3.
4.
Create a CRBasic program that includes an AVW200() instruction for each
of the sensors.
