7.1.2 Using DVWTool
The Dynamic Vibrating-Wire Tool Box ( DVWTool ) is a software package that
enables a PC to communicate with the CDM-VW300 via USB, configure CDM-
VW300 settings, and display the output of attached sensors. No datalogger is
required. Data are output in the main window table, on a line graph, and in a
rainflow histogram.
Users of the CDM-VW300 should become familiar with the function and
operation of
DVWTool . Detailed information about this software can be found in
the DVWTool Help system.
7.1.2.1 Ensure Connection is Active
The installation of DevConfig 2.04 or later or DVWTool 1.0 or later automatically
installs the drivers required to make a connection between the CDM-VW300 and
the PC. Do not connect a USB cable between your CDM-VW300 and the PC
until after
DevConfig or DVWTool has been installed. Before starting DVWTool ,
ensure that the CDM-VW300 analyzer is connected to the PC via USB cable.
After opening
DVWTool , choose the CDM-VW300 port from the Com Port
dropdown list, as indicated in Figure 7-1. Click the Connect button.
