ADVField Software Manual (September 1, 2001) 5
Section 2. Real-Time Data Acquisition (ADF.EXE)
The most common method of collecting ADV data is using SonTek’s real-time data acquisition
software, ADVField (
ADF.EXE
). This program is written for DOS on a PC-compatible computer
with the minimum hardware requirements shown below.
• 33 MHz 386/387 with math co-processor
• 640K RAM
• Hard disk
• Color VGA graphics
• One available serial communication port
The ADVField software also includes a version of the program compiled for 386/387 computers
without the math co-processor (
ADFSX.EXE
). When possible, we recommend using a computer
with the minimum hardware outlined above.
The data acquisition software has three modes of operation: setup, boundary adjustment, and
data acquisition. The program starts in the setup mode, where you are presented with a menu to
specify data collection parameters. Once complete, you enter the boundary adjustment mode by
selecting
START Data Acquisition
. In the boundary adjustment mode, the ADV searches for the
presence of a boundary (bottom, surface, or side) in front of the probe while displaying the dis-
tance to the boundary on the screen. Data acquisition mode is entered from the boundary adjust-
ment mode by pressing
F10
. In the data acquisition mode, the program collects, displays, and re-
cords (if enabled) velocity data until stopped by the operator. While data are being collected, you
can change the display without interrupting the sampling or recording of the data.
The description of the data acquisition software is divided into the following sections.
• Probe Configuration Files (§2.1) – A description of the ADV probe configuration files that
must be specified before starting the data acquisition software.
• Command Line Options and Software Parameter Files (§2.2) – A description of options that
can be added to the DOS command line to modify the operation of the data acquisition soft-
ware and of files generated by the software to record user parameter settings.
• Setup Mode (§2.3) – The first data acquisition screen that allows modification of ADV data
collection parameters (temperature, salinity, sampling rate, velocity range, etc.).
• Boundary Adjustment Mode (§2.4) – The second data acquisition screen that displays the
range from the ADV probe to the boundary (if detected).
• Data Acquisition Mode (§2.5) – The final data acquisition screen that provides a real-time
tabular and graphical display of ADV data.
• Recorded Data (§2.6) – A description of the data recorded in the ADV binary files.
