PCI-1718 Series User Manual 2
Chapter 1 Introduction
Thank you for buying the Advantech PCI-1718HDU/HGU. PCI-
1718HDU/HGU is a PCI-Bus multifunction card for IBM PC/XT/AT or
compatible computers. It offers the five most desired measurement and
control functions:
• 12-bit A/D conversion
• D/A conversion
• Digital input
• Digital output
• Timer/counter.
A programmable-gain instrument amplifier lets you acquire different
input signals without external signal conditioning. An onboard 1 K word
FIFO buffer provides high-speed data transfer and predictable perfor-
mance under Windows. Automatic channel scanning circuitry and
onboard SRAM let you perform multiple-channel A/D conversion with
DMA and individual gains for each channel.
PCI-1718HDU/HGU is compatible* with its ISA-Bus predecessor, the
PCL-818HD/HG. This puts rich software support and a wide variety of
external signal conditioning boards at your disposal.
The following sections of this chapter will provide further information
about features of the multifunction cards, a Quick Start for installation,
together with some brief information on software and accessories for the
PCI-1718 cards.
Note* 1. PCI-1718HDU/HGU is register-level- pro-
gramming compatible with PCL-818HD/HG
2. Due to the difference between ISA and PCI
architecture, we use “interrupt + FIFO” to emu-
late the DMA function. But it makes no differ-
ence to your programming and applications.

3 Chapter1
1.1 Features
• Register level programming compatible with PCL-818HD/HG
• 16 single-ended or 8 differential A/D inputs, switch selectable
• 12-bit A/D converter, up to 100 kHz sampling rate
• Programmable gain for each input channel
• Automatic Channel/Gain Scanning
• On-board 1 K word FIFO buffer with software selectable interrupt
• Software selectable Bipolar/Unipolar analog input ranges
• 16 digital inputs and 16 digital outputs, TTL/DTL compatible
• One 12-bit analog output channel
• Data transfers by program control and interrupt handler routine
• Universal PCI-Bus (Support 3.3V or 5V PCI-Bus signal)
• BoardID switch
PCI-1718HDU/HGU offers the following main features:
PCI-Bus Plug & Play
The PCI-1718 cards use a PCI controller to interface the card to the PCI
bus. The controller fully implements the PCI bus specification Rev 2.2.
All configurations related to the bus, such as base address and interrupt
assignment, are automatically controlled by software. No jumper or
switch is required for user configuration.
Automatic Channel/Gain Scanning
PCI-1718HDU/HGU features an automatic channel/gain scanning circuit.
This circuit, instead of your software, controls multiplexer switching dur-
ing sampling. On-board SRAM stores different gain values for each chan-
nel. This combination lets user perform multi-channel high-speed
sampling (up to 100 kHz) for each channel.

PCI-1718 Series User Manual 4
Onboard FIFO
There are 1 K samples FIFO for A/D (AI) on PCI-1718HDU/HGU. This
is an important feature for faster data transfer and more predictable per-
formance under Windows system.
Onboard Programmable Timer/Counter
PCI-1718HDU/HGU provides a programmable timer counter for generat-
ing pacer trigger for the A/D conversion. The timer/counter chip is
82C54, which includes three 16-bit counters of 10 MHz clock. One
counter is used as an event counter for counting events coming from the
input channel. The other two are cascaded together to make a 32-bit timer
for pacer trigger time base.
BoardID Switch
PCI-1718HDU/HGU has a built-in DIP switch that helps define each
card’s ID when multiple PCI-1718HDU/HGU cards have been installed
on the same PC chassis. The BoardID setting function is very useful when
building a system with multiple PCI-1718 cards. With the correct Boar-
dID settings, you can easily identify and access each card during hard-
ware configuration and software programming.
1.2 Applications
• Transducer and sensor measurements
• Waveform acquisition and analysis
• Process control and monitoring
• Vibration and transient analysis
Note: For detailed specifications of the PCI-
1718HDU/HGU, please refer to Appendix A.

5 Chapter1
1.3 Installation Guide

1718HDU/HGU card:
• Device Drivers (on the companion CD-ROM)
• LabVIEW driver
• Advantech ActiveDAQ
• Advantech ADAQView
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 CD-
ROM at no extra charge. It also comes with all Advantech DA&C cards.

help boost your application performance. Advantech Device Drivers for
Windows 98/2000/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 Appendix C, Register Structure and Format,
or to the example codes included on the companion CD-ROM.

2.1 Unpacking
After receiving your PCI-1718HDU/HGU package, please inspect its
contents first. The package should contain the following items:
• PCI-1718HDU or PCI-1718HGU card
• Companion CD-ROM (Device Drivers included)
• User Manual
The PCI-1718 cards harbor certain electronic components vulnerable to
electrostatic discharge (ESD). ESD can easily damage the integrated cir-
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
damaged components, etc.). If the card is visibly damaged, please
notify our service department or our local sales representative immedi-
ately. 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.
• Whenever you handle the card, grasp it only by its edges. DO NOT
TOUCH the exposed metal pins of the connector or the electronic com-
ponents.
