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 manual,
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

• Features

• Applications

• Installation Guide

• Accessories

Chapter 1 Introduction

Thank you for buying the Advantech PCM-3780. The PCM-3780 is a
general purpose multiple channel counter/timer card for the PC/104 bus.
It targets the AM9513 to implement the counter/timer function by CPLD.
It provides two 16-bit counter channels and 24-ch digital TTL I/O.

The I/O bits are divided into three 8-bit I/O ports: A0, B0 and C0. You
can configure each port as either input or output via software. The power­ful Advantech-designed counter functions fulfill your industrial or labo­ratory application needs.

The following sections of this chapter will provide further information
about features of the multifunction cards, a quick startup guide for instal­lation, together with some brief information on software for the PCM-

3780 card.

1.1 Features

• 2 independent 16-bit counters

• 2 programmable clock sources

• 24-ch digital TTL I/O

• Up to 20 MHz input frequency

• Multiple counter clock source selectable

• Counter output programmable

• Counter gate function

• Flexible interrupt source select

1.4 Software Overview

Advantech offers a rich set of DLL drivers, third-party driver support and
application software to help fully utilize the functions of your PCM-3780
card:

1.4.1 Device Drivers (on the companion CD-ROM)

• LabVIEW driver

• Advantech ActiveDAQ

• Advantech GeniDAQ

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 another option for register-level programming,
although it is not recommended due to its laborious and time-consuming
nature.

1.4.2 Device Drivers

The Advantech Device Drivers software is included on the companion
CD-ROM at no extra charge. It also comes with all Advantech DA&C
cards. Advantech’s device drivers feature a complete I/O function library
to help boost your application performance. The Advantech

Device Drivers for Windows 2000/XP works seamlessly with develop­ment tools such as Visual C++, Visual Basic, Inprise C++ Builder and
Inprise Delphi.

1.4.3 Register-level Programming

Register-level programming is reserved for experienced programmers
who find it necessary to write code directly at the level of device regis­ters. Since register-level programming requires much effort and time, we
recommend that you use the Advantech Device Drivers instead. How­ever, if register-level programming is necessary, 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.

unpacking and step-by-step procedures

for card

hardware installation.

Chapter 2 Hardware Installation

2.1 Unpacking

After receiving your PCM-3780 package, please inspect its contents first.
The package should contain the following items:

• PCM-3780 card

• Companion CD-ROM (DLL driver included)

• User Manual

The PCM-3780 card has electronic components vulnerable to

static discharge

and certain components if preventive measures are not carefully paid
attention to. Before removing the card from the antistatic plastic bag, you
should take following precautions to ward off possible ESD damage:

• Touch the metal part of your computer chassis with your hand to dis­charge static electricity accumulated on your body. Or 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 from
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 Advantech’s service department or the
local sales representative immediately. Avoid installing a damaged card
into your system. Also, pay extra caution to the following aspects to
ensure proper installation:

• Avoid physical contact with materials that could hold static electricity
such as plastic, vinyl and Styrofoam.

• Whenever you handle the card, hold it only by its edges. DO NOT
TOUCH the exposed metal pins of the connector or the electronic com­ponents.

Note Keep the anti-static bag for future use. You might

need the original bag to store the card if you have to
remove the card from the PC or transport it else­where.
