1. Included LabView Application
1.1 Installation:
In order to use the STM-1 LabView software, one must first install the National Instruments LabView run-time engine. This can
be accomplished by running the install program and following the standard installation procedure.
With LabView installed, copy the STM-1 VI (Virtual Instrument) to a folder of your choice. If there is a file named Stm1.dat
included with your VI, you may also copy this file into the same folder. This file will provide density and z-ratio for several
common materials. It is not necessary to include it, and it can be altered through the application at a later time.
1.2 Setup:
When the VI is executed, it will initially be stopped. While the VI must be running to do anything useful, first it must be
configured to communicate with the STM-1. Select the configure tab on the tab control, and make sure that the COM PORT
selector is set to correspond with the port of the PC that the STM-1 is connected to. The SLAVE ADDRESS, BAUD RATE, and
CHECKSUM values must also correspond with the jumper settings on the STM-1 unit. When all of these are set correctly, click
the START button to begin. If the PC cannot communicate with the STM-1 due to a bad connection or incorrect settings, a pop
up box will appear in a few seconds, indicating the error, and giving the choice to stop the VI or to simulate the existence of an
STM-1 (This feature is included for learning and demonstration purposes). Once the VI is running, changing any of the
previously mentioned parameters will cause it to quit (with the exception of changing the COM PORT or SLAVE ADDRESS to
communicate with a second STM-1 unit).
Once running, as long as an appropriate crystal is connected, rate and thickness information will be displayed on the front panel.
1.3 Front Panel Controls:
Including controls on the Rate and Thickness tabs.
The START button will start the VI.
The STOP button will stop the VI. The STM-1 board itself, however, continues to make measurements using the last set of
material properties it was sent.
