PCI-1724U User Manual 2
Chapter 1 Introduction
Thank you for buying the Advantech PCI-1724U. The PCI-1724U is an
isolated multiple channels analog output card for PCI bus, and each ana-
log output channel is equipped with a 14-bit, double-buffered DAC.
The PCI-1724U is an ideal solution for industrial applications where mul-
tiple analog output channels are required.
The following sections of this chapter will provide further information
about features of multifunction cards, a Quick Start for installation,
together with some brief information on software and accessories for the
PCI-1724U card.
1.1 Features
• 32 isolated analog output channels
• A 14-bit DAC is equipped for each of the analog output channels
• Flexible output range: ±10 V, 0 ~ 20 mA, 4 ~ 20 mA
(0~20mA, 4~20mA is selected by software, please refer to Appendix D
Calibration Utility.)
• Synchronized output function
• Output values kept after system hot reset
• Board ID
The Advantech PCI-1724U offers the following main features:
Flexible Voltage Output Range
The PCI-1724U provides a fixed voltage output range of ±10 V for a flex-
ible range that can be used for a many different applications. Users can
define the specific voltage output range and output data format via the
enclosed software utility and driver.

3 Chapter1
Keeps Output Values After System Reset
Users can independently set the 32 outputs to different ranges: ±10 V, 0 ~
20 mA or 4 ~ 20 mA, and all ranges are software selectable. When the
system is hot reset (power not shut down), the PCI-1724U can either
retain the last analog output values, or return to its default configuration,
depending on the jumper setting. This practical function eliminates dan-
gers caused by improper operation during unexpected system resets.
Board ID
The PCI-1724U has a built-in DIP Switch that helps define each card’s ID
when multiple PCI-1724U cards have been installed on the same PC
chassis. The board ID setting function is very useful when users build
their system with multiple PCI-1724U cards. With correct Board ID set-
tings, you can easily identify and access each card during hardware con-
figuration and software programming.
1.2 Applications
• Process control
• Programmable voltage source
• Programmable current sink
• Servo control
• Multiple loop PID control
Note: For detailed specifications of the PCI-1724U, please
refer to Appendix A, Specifications.

1.4 Software Overview
Advantech offers a rich set of DLL drivers, third-party driver support and
application software to help fully exploit the functions of your PCI-
1724U card:
• Device Drivers (on the companion CD-ROM)
• LabVIEW driver
• Advantech ActiveDAQ
• Advantech GeniDAQ
Programming choices for DA&C cards: You may use Advantech applica-
tion software such as Advantech Device Drivers. On the other hand,
advanced users are allowed another option for register-level program-
ming, although not recommended due to its laborious and time-consum-
ing nature.
Device Drivers
The Advantech Device Drivers software is included on the companion
CD-ROM at no extra charge. It also comes with all the Advantech DA&C
cards. Advantech’s Device Drivers features a complete I/O function
library to help boost your application performance. The Advantech
Device Drivers for Windows 2000/95/98/ME/XP works seamlessly with
development tools such as Visual C++, Visual Basic, Inprise C++ Builder
and Inprise Delphi.
Register-Level Programming
Register-level programming is available for experienced programmers
who find it necessary to write code directly at the level of the device reg-
ister. 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 indispensable, 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.
