Product Warranty (2 years)

Advantech warrants to you, the original purchaser, that each of its prod-

ucts will be free from defects in materials and workmanship for two years

from the date of purchase.

This warranty does not apply to any products which have been repaired or

altered by persons other than repair personnel authorized by Advantech,

or which have been subject to misuse, abuse, accident or improper instal-

lation. Advantech assumes no liability under the terms of this warranty as

a consequence of such events.

Because of Advantech’s high quality-control standards and rigorous test-

ing, most of our customers never need to use our repair service. If an

Advantech product is defective, it will be repaired or replaced at no

charge during the warranty period. For out-of-warranty repairs, you will

be billed according to the cost of replacement materials, service time and

freight. Please consult your dealer for more details.

If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For

example, CPU speed, Advantech products used, other hardware

and software used, etc.) Note anything abnormal and list any

onscreen messages you get when the problem occurs.

2. Call your dealer and describe the problem. Please have your man-

ual, product, and any helpful information readily available.

3. If your product is diagnosed as defective, obtain an RMA (return

merchandize authorization) number from your dealer. This allows

us to process your return more quickly.

4. Carefully pack the defective product, a fully-completed Repair and

Replacement Order Card and a photocopy proof of purchase date

(such as your sales receipt) in a shippable container. A product

returned without proof of the purchase date is not eligible for war-

ranty service.

5. Write the RMA number visibly on the outside of the package and

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.

1.3 Installation Guide

Before you install your PCI-1724U card, please make sure you have the

following necessary components:

• PCI-1724U DA&C card

• PCI-1724U User’s Manual

• Advantech DLL drivers (Included in the companion CD-ROM)

• Wiring cable PCL-10162 (option)

• Wiring board ADAM-3962 (option)

• Personal computer or workstation with a PCI-bus slot (running Win-

dows 2000/95/ 98/ME/XP)

Some other optional components are also available for enhanced opera-

tion such as application software ActiveDAQ, GeniDAQ and other third-

party software packages

After you get the necessary components and maybe some of the accesso-

ries for enhanced operation of your PCI-1724U multifunction card, you

can begin the installation procedure. Figure 1-1 on the next page provides

a concise flow chart to give a broad picture of the software and hardware

installation procedures:
