PCIS-LVIEW NT/2000/98/XP Utilities
3.1 NuDAQ Registry/Configuration utility (PciUtil)
PciUtil is used to register NuDAQ PCI card drivers (Windows NT4 only), remove installed drivers (Windows NT4 only),
and modify the allocated buffer sizes of AI, AO, DI and DO (Windows NT/2000/98/XP). The default location of this utility
is <InstallDir>\Util directory. Because it has been mentioned in the previous chapter, we will not introduce it here. Please
refer to the chpater “NuDAQ PCI Configuration Utility” in the NuDAQ PCI and NuIPC CompactPCI DAQ Cards Software
Installation Guide.
3.2 Data File Converter utility (DAQCvt)
The data files, generated by the PCIS-LVIEW 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-LVIEW 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.
