Chapter 1 Introduction
Thank you for buying the Advantech PCIE-1744. The PCIE-1744 is a
simultaneous 4-channel analog input card with high sampling rates. It is
an advanced-performance data acquisition card based on 32-bit PCI-
express bus architecture. The maximum sampling rate of PCIE-1744 is up
to 30 MS/s.
1.1 Features
The PCIE-1744 offers the following main features:
• 32-bit PCI Express bus Mastering DMA data transfer
• Four A/D converters for simultaneous sampling
• 12-bit A/D converter with up to 30 MS/s
• 4 single-ended analog input channels
• Programmable gain for each input channel
• On board FIFO memory
• Multiple A/D triggering modes

Some of the features are described in details from the next page.

3 Chapter1
1.1.1 32-bit PCI bus Mastering DMA Data Transfer
The PCIE-1744 supports PCI bus mastering DMA for high-speed data
transfers. By setting aside a block of memory in the PC, the card performs
bus-mastering data transfers without CPU intervention, freeing the CPU
to perform other more urgent tasks such as data analysis and graphic
manipulation. The function allows users to run all I/O functions simulta-
neously at full speed without losing data.
1.1.2 Four A/D Converters for Simultaneous Sampling
The PCIE-1744 is capable of simultaneous sampling with their 4 identical
circuits and a dedicated A/D converter for each analog input channel.
When the time relationship between inputs is important, this feature lets
you sample simultaneously.
1.1.3 Supports S/W, Internal & External Pacer Triggering
The PCIE-1744 supports three kinds of trigger modes for A/D conver-
sion: software triggering, internal pacer triggering and external pacer trig-
gering. The software trigger can acquire a sample whenever needed,
while the internal pacer saves CPU resources by triggering the sampling
at a pre-programmed frequency. An external pacer can also be used for
triggering by externally connected equipment.
1.1.4 Onboard FIFO Memory
There is 32k of FIFO sample memory on PCIE-1744.. This is an impor-
tant feature for faster data transfers and more predictable performance
under Windows systems.
1.1.5 Auto Calibration
The PCIE-1744 features software auto calibration. There is no variable
resister trimming required. This is convenient for user calibration.
Note: For detailed specifications of the PCIE-1744,
please refer to Appendix A, Specifications.

1.4.1 Programming Choices for DA&C Cards
You may use Advantech application software such as Advantech Device
Drivers. On the other hand, advanced users may choose register-level
programming, although it is not recommended due to its laborious and
time-consuming nature.
1.4.2 Device Drivers
The Advantech Device Drivers software is included on the companion
CD-ROM. It also comes with all Advantech DA&C cards. Advantech’s
device drivers feature a complete I/O function library to help boost your
application performance. The Advantech Device Drivers for Windows
98, 2000 and XP works seamlessly with development tools such as Visual
C++, Visual Basic, Borland C++ Builder and Borland Delphi.
1.4.3 Register-Level Programming
Register-level programming is reserved for experienced programmers
who find it necessary to write code directly at the level of device regis-
ters. Since register-level programming requires much effort and time, we
recommend that you use the Advantech Device Drivers instead. How-
ever, if register-level programming is necessary, you should refer to the
relevant information in Appendix C, Register Structure and Format,
or to the example codes included on the companion CD-ROM.
