1. Introduction
Thank you for buying the Advantech PCI-1711/1731 PCI card. The
Advantech PCI-1711/1731 is a powerful data acquisition (DAS) card for
the PCI bus. It features a unique circuit design and complete functions
for data acquisition and control. PCI-1711/1731 provides specific
functions for different user requirements:
PCI-1711 12-bitLow-costMultifunctionDAScard
PCI-1731 12-bitLow-costMultifunctionDAScardw/oanalogoutput
The following sections of this chapter will provide further information
about features of the DAS cards, a Quick Start for installation, together
with some brief information on software and accessories for the PCI-
1711/1731card.
1.1 Features
The Advantech PCI-1711/1731 provides users with the most requested
measurement and control functions as seen below:
q16-channel Single-Ended A/D Input
q12-bit A/D conversion with up to 100 kHz sampling rate
q16-channel Digital Input
q16-channel Digital Output
q2-channelD/A Output (onlyfor PCI-1711)
qProgrammableCounter/Timer
qAutomatic Channel/Gain Scanning
TheAdvantech PCI-1711/1731offers the followingmain features:
Plug-and-Play Function
The Advantech PCI-1711/1731 is a Plug-and-Play device, which fully
complieswith the PCISpecification Rev 2.1. During card installation, all
bus-related configurations such as base I/O address and interrupts are
conveniently taken care of by the Plug-and-Play function. You have
virtually no need to set any jumpers or DIP switches.
Flexible Input Types and Range Settings
The PCI-1711/1731 features an automatic channel/gain scanning
circuit. This circuit design controls multiplexer switching during
sampling. Users can set different gain values for each channel

Chapter 1
PCI-1711/1731 User’s Manual Advantech Co., Ltd.

according to their needs for the corresponding range of input voltage.
The gain value settings thus selected is stored in the SRAM. This
flexible design enables multi-channel and high-speed sampling for
high-performance data acquisition (up to 100 KS/s .)
On-boardFIFO(First-In-First-Out) Memory
The PCI-1711/1731 provides an on-board FIFO memory buffer, storing
up 1 to 1K A/D samples. Users can either enable or disable the
interrupt request feature of the FIFO buffer. While the interrupt request
for FIFO is enabled, users are allowed to specify whether an interrupt
request will be sent with each sampling action or only when the FIFO
buffer is half saturated. This useful feature enables a continuous high-
speed data transfer with a more predictable performance on operating
systems.
Optional D/A Output for Cost Savings
The PCI-1711 goes further with 2 analog output channels, while the
PCI-1731 doesn’t. It is for users to differentiate between the PCI-1711
and the PCI-1731 according to what they really need as the best
solution with no extra cost.
16 Digital Inputs and 16 Digital Outputs
The PCI-1711/1731 provides 16 digital input channels and 16 digital
output channels. Users are left with great flexibility to design and
customize their applications according to their specific needs.
On-board Programmable Counter
ThePCI-1711/1731isequipped with a programmable counter, which
can serve as a pacer trigger for A/D conversions. The counter chip is
an 82C54 or its equivalent, which incorporates three 16-bit counters on
a 10 MHz clock. One of the three counters is used as an event counter
for input channels or pulse generation. The other two are cascaded
into a 32-bit timer for pacer triggering.
Note:
✎Pace trigger determines how fast A/D conversion will be done in pacer
trigger mode.
✎For detailed specifications of the PCI-1711/1731, please refer to Appen-
dix A, Specifications.

1.2 Installation Guide
Before you install your PCI-1711/1731 card, please make sure you have
the following necessary components:
qPCI-1711orPCI-1731DAScard
qPCI-1711/1731User’sManual
qDriversoftware Advantech DLL drivers
(included in the companion CD-ROM)
qWiringcable PCL-10168
qWiringboard PCLD-8710,ADAM-3968
qComputer Personal computer or workstation with a
PCI-bus slot (running Windows 95/98/NT)
Some other optional components are also available for enhanced
operation:
qApplicationsoftware ActiveDAQ, GeniDAQ or other third-party
software packages
After you have got the necessary components and maybe some
accessories for enhanced operation of your DAS card, you can then
begin the Installation procedures. Figure 1-1 on the next page pro-
vides a concise flow chart to give users a broad picture of the software
and hardware installation procedures:

1.3 Software
Advantech offers a rich set of DLL drivers, third-party driver support
and application software to help fully exploit the functions of your
PCI-1711/1731card:
lDLLdriver (on thecompanion CD-ROM)
lLabviewdriver
lAdvantech ActiveDAQ
lAdvantech GeniDAQ
For more information on software, please refer to Chapter 4, Software
Overview.
Users who intend to program directly at the registers of the DAS
device can have register-level programming as an option. Since
register-level programming is often difficult and laborious, it is
usually recommended only for experienced programmers. For more
information, please refer to Appendix C, Register Structure and
Format.
1.4 Accessories
Advantech offers a complete set of accessory products to support the
PCI-1711/1731 cards. These accessories include:
Wiring Cable
qPCL-10168 The PCL-10168 shielded cable is specially designed
for PCI-1711/1731 cards to provide high resistance to noise. To
achieve a better signal quality, the signal wires are twisted in such a
way as to form a “twisted-pair cable”, reducing crosstalk and noise
from other signal sources. Furthermore, its analog and digital lines
are separately sheathed and shielded to neutralize EMI/EMC
problems.
Wiring Boards
qADAM-3968 TheADAM-3968 is a 68-pin SCSI wiring terminal
modulefor DIN-rail mounting. Thisterminal module can be readily
connected to the Advantech PC-Lab cards and allow easy yet
reliable access to individual pin connections for the PCI-1711/1731
card.

qPCLD-8710 ThePCLD-8710 is a DIN-rail mounting screw-
terminal board to be used with any of the PC-LabCards which have
68-pinSCSI connectors. The PCLD-8710features the following
functions:
l2 additional 20-pin flat-cable connectors for digital input and
output
lReserved space on the board to meet future needs for signal-
conditioning circuits (low-pass filter, voltage attenuator and
current shunt)
lIndustrial-grade screw-clamp terminal blocks for heavy-duty and
reliable connections.
