- Adaptations for Agilent's VEE Version 4.0 and newer
are available for all data acquisition cards.
- The example shown here displays up to 8 channels at
once. There are other examples for data logging and a scope-like
application.

- All card's drivers support National Instrument's
LabVIEW version 4.0 and higher. The adaptation consists of a number
of VIs that provide the necessary functionality.
- The example shown here displays the waveform on
input A1.

An example for using LabWindows. The standard data
acquisition card C/C++ language interface was used. We are happy to
show, with permission by ELEXIENCE,
France, this example, written for a DAQ pci508MF. It controls the A/D
converter as well as the I/O ports and the D/A converters. It runs
without changes also with a DAQ i508MF PCMCIA card.

- All card's drivers support Microsoft® Visual Basic®
version 4.0 and higher.
- The adaptation consists of a small set of functions
(shown above as 'DaqProcedures') for initializing the card, changing
the card's settings, reading and writing data.
- The example shown here displays readings on input
A1.
- Full error handling is provided. Every function
returns its status. In case an error occurs, for an error number a
meaningful error message can be obtained.

- Microsoft® Visual C++®, version 2.0 and higher,
is supported by all cards. Full error handling and parameter range
checks are provided. This reduces program development time, since
errors can be found where they originate, and not when they occur.
- The example shown here displays the reading on
input A1.
- Example's source code, workspace files and import
libraries included.

- The Borland C++ example is similar to the Visual
C++ example. The example's source code, a makefile and import
libraries are provided.
- Borland C++ Version 4.5 and 5.0 are supported by
all data acquisition cards.

- CEC/Keithleys TestPoint is also supported by all
cards.
- The example includes a graphical user interface for
card's settings and a display. Here the waveform on input A1 is
shown. Trigger conditions, sample rate and other options can be set
freely.

- All card's drivers support TransEra's HTBasic. The
adaptation uses a CSUB interface that can be included in any HTBasic
version 6.1 or newer.
- The example shown here displays the waveform on
input A1 and the status of the digital inputs. There are other
examples available for operating the digital I/O and the D/A
converters in multifunction cards.

Ines DAQ tools can be used without any installed
application. They are intended for easy data collection and
installation checks.
Hardware Test:
- The Hardware Test provides a quick check ensuring
the card's resources are available and the card is working fine.
- After showing the card's identification, the
resources are displayed.
- Finally, the driver is initialized, the card takes
a sample. The result is shown, indicating proper installation or
problems.
- In case of installation problems, the Hardware Test
can be instructed to create a log file. With aid of this file, the
support can recognize the problem quickly and give advice.

Data Logger:
- The Data logger is an easy means to capture data without
the need of a self-written application. Furthermore, the optimized
design cares for maximum throughput.
- Data is written in binary directly to disk. This
ensures maximum speed and minimum disk space consumption. The
maximum number of samples is 1G, according to 2GByte file size.
- With the demangle data tool, binary data can be
converted to ASCII data, terminated by CRLF. This data format can be
imported into nearly all existing database or spreadsheet
applications.
- In case of installation problems, the Hardware Test
can be instructed to create a log file. With aid of this file,
support can recognize the problem quickly and give advice.

Throughput Test:
- The Throughput test checks the maximum safe system
throughput. Using PCMCIA cards, it is highly system dependent, and
at speeds above 200kSamples per second, it is better to know the
system can handle the speed in advance.
- Mainly, the program operates as Data logger that repeats
logging a huge amount of data (20MByte) with increasing sample
rates.
- The result is a safe speed, at which it is unlikely
that FIFO overruns or other errors occur.
- The program can check the performance for other
data file sizes or FIFO sizes as well.
- This test was performed on a Pentium I (200MHz)
computer with a PCMCIA card and a PCMCIA drive attached to ISA bus.
- For better performance, we recommend PCMCIA
drives attached to PCI bus.
