Downloading Data to A Computer
“COMPUDAT” is a windows-based program from TSI designed to download
the data stored in the memory of the RVD
to a computer. This data includes the
test ID, measurement, unit of measure, flow area, and time constant. This data is
date and time stamped. In addition, the statistics for each test ID are provided.
The file containing the downloaded data is sorted and tab delimited to allow it to
be imported into a spreadsheet for further data analysis.
To load COMPUDAT on your computer, use the following procedure, also
found on the disk:
•
For Windows 3.1: Select File, Run, and type “A:\setup.exe”
•
For Windows 95/98: Select Start, Run, and type “A:\setup.exe”
Once you open the program, it is self-directing and provides all the necessary
instructions for downloading data.
To download data from the RVD, connect the supplied computer interface cable
to the RVD and to a computer serial port. Any serial port from COM1 to COM4
can be used.
Data Acquisition (Polling)
The RVD is designed to allow you to perform polling through the use of a
computer. To do this, your computer must be connected and in Terminal mode.
The baud rate for the computer and the RVD must be set to the same value. For
details on viewing or changing the baud rate, see
Changing the Baud Rate
section in Chapter 2. You must then send an upper case V to the instrument.
You must write your own routine (program) to obtain information at specific
intervals from the RVD. The meter will only send information when the
READ
key is pressed or after the computer has sent a “V” command to the RVD.
