Chapter

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.

www.advantech.com

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

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

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.
