6.2 PCIS-DASK Data File Converter utility (DAQCvt)
The data files, generated by the PCIS-DASK functions performing continuous data acquisition followed by storing the
data to disk, is written in binary format. Since a binary file can’t be read by the normal text editor and can’t be used to
analyze the accessed data by Excel, PCIS-DASK provides a convenient tool DAQCvt to convert the binary file to the file
format read easily. The default location of this utility is <InstallDir>\Util directory. The DAQCvt main window is as the
following figure:
The DAQCvt main window includes two frames. The upper frame, Input File frame is used for the source data file and
the lower frame is used for the destination file.
To load the source binary data file, type the binary data file name in File Path field or click Browser button to select
the source file from Input File frame, and then click Load button. As the file is loaded, the information related to the data
file, e.g. data type, data width, AD Range, …etc., are shown in the corresponding fields in “Input File” frame, and the
default converted data file path and format are also listed as the figure below.
The default destination file with a .cvt extension is located in the same directory as the source one. To change the
default setting, type the file path you wish or click the Browser button from Output File frame to select the destination file
location.
DAQCvt provides three types of data format conversion.
Scaled data to text file :
The data in hexadecimal format is scaled to engineering unit (voltage, ample, …etc) according to the card
type, data width and data range and then written to disk in text file format. This type is available for the data
accessed from continuous AI operation only.
Scaled data to binary file (float) :
