PCI-1727U User Manual 2
Chapter 1 Introduction
Thank you for being an Advantech PCI-1727U customer. PCI-1727U
provides twelve 14-bit analog output channels, and is pin-compatible
with the ISA PCL-727 card for easy migration. It supports both +/-10V
and 0~ 20mA current loop (sink) output. The card’s on board DC-to-DC
converter ensures the full 10V analog output is always available.
Each analog output channel has a built-in fuse to protect the circuit, PC
and the external devices. PCI-1727U is an ideal, economical solution for
the applications which require multiple PID control loops.
In addition to its analog outputs, PCI-1727U provides 16 TTL DI and 16
TTL DO channels that are easily applied with industrial on/off control
applications.
1.1 Features
• 12 Analog output channels
• 14-bit resolution
• Multiple voltage output ranges ± 10V output and 0~20mA current loop
(sink)
• 16 digital input and 16 digital output channelsTTL compatible
• Board ID
• Calibration
• Retain the latest analog/digital output value after system reset
The Advantech PCI-1727U offers the following main features:
Calibration Function
The PCI-1727U provides a manual calibration function through a utility.
The program helps the user to easily complete the calibration procedures
Flexible Voltage Output Range
The PCI-1727U provides a fixed voltage output range of ± 10V to fulfill
your flexible range application requirements. Users can define the spe-
cific voltage output range and output data format via the software utility
and driver.

3 Chapter1
Retains the Output Values after System Reset
Users can independently set the 12 outputs to different ranges: ±10V and
0~20mA. All ranges are software selectable. When the system is hot reset
(power not shut down), the PCI-1727U can either retain the last analog
output values, or return to its default configuration, according to the
jumper setting. This practical function eliminates danger caused by miss-
operation during unexpected system reset.
BoardID
The PCI-1727U has a built-in DIP Switch that helps define each card’s ID
when multiple PCI-1727U cards have been installed on the same PC
chassis. With correct BoardID settings, you can easily identify and access
each card during hardware configuration and software programming.
1.2 Applications
• Process control
• Programmable voltage source
• Programmable current sink
• Servo control
• Multiple loop PID control
1.3 Installation Guide

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-1727U card:
• Device Drivers (on the companion CD-ROM)
• LabVIEW driver
• Advantech ActiveDAQ Pro
Programming Choices for DA&C Cards
You may use Advantech application software such as Advantech Device
Drivers. On the other hand, advanced users can use register-level pro-
gramming, although this is not recommended due to its laborious and
time-consuming nature.
Device Drivers
Advantech Device Driver software is included on the companion
CDROM at no extra charge. It also comes with all Advantech DA&C
cards. Advantech’s Device Drivers features a complete I/O function
library to help boost your application performance. Advantech Device
Drivers for Win 2000/XP works seamlessly with development tools such
as Visual C++, Visual Basic, Borland C++ Builder and Borland 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 Chapter 4, Register Structure and Format, or
to the example codes included on the companion CD-ROM.

Builder. The step-by-step instructions on how to build your own applica-
tions using each development tool will be given in the Device Drivers
Manual. Moreover, a rich set of example source code is also given for
your reference.
1.5.1 Programming Tools
Programmers can develop programs using these development tools:
• Visual C++
• Visual Basic
• Delphi
• C++ Builder
For instructions on how to begin programming in each development tool,
Advantech offers a Tutorial Chapter in the Device Drivers Manual for
your reference. Please refer to the corresponding sections in this chapter
on the Device Drivers Manual to begin your programming efforts. You
can also look at the example source code provided for each programming
tool, since they can get you very well oriented.

1.5.2 Programming with Device Drivers Function Library
Advantech Device Drivers offer a rich function library that can be utilized
in various application programs. This function library consists of numer-
ous APIs that support many development tools, such as Visual C++,
Visual Basic, Delphi and C++ Builder.
1.5.3 Troubleshooting Device Drivers Error
Driver functions will return a status code when they are called to perform
a certain task for the application. When a function returns a code that is
not zero, it means the function has failed to perform its designated func-
tion. To troubleshoot the Device Drivers error, you can pass the error
code to DRV_GetErrorMessage function to return the error message.
Alternatively, you can refer to the Device Drivers Error Codes Appendix
in the Device Drivers Manual for a detailed listing of Error Codes, Error
IDs and the Error Messages.

cuits and certain components if preventive measures are ignored.
Before removing the card from the antistatic plastic bag, you should take
the following precautions to ward off possible ESD damage:
Touch the metal part of your computer chassis with your hand to dis-
charge the static electricity accumulated on your body. Alternatively, one
can also use a grounding strap.
Touch the anti-static bag to a metal part of your computer chassis before
opening the bag.
Take hold of the card only by the metal bracket when removing it out of
the bag.
After taking out the card, you should first:
Inspect the card for any possible signs of external damage (loose or dam-
aged components, etc.). If the card is visibly damaged, please notify our
service department or our local sales representative immediately. Do not
install a damaged card into your system.
Also, pay extra caution to the following aspects during installation:
Avoid physical contact with materials that could hold static electricity
such as plastic, vinyl and Styrofoam.

11 Chapter2
Whenever you handle the card, grasp it only by its edges. DO NOT
TOUCH the exposed metal pins of the connector or the electronic compo-
nents.
