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

ship it prepaid to your dealer.

Step 2. Contact your distributor, sales representative, or Advantech's cus-

tomer service center for technical support if you need additional

assistance. Please have the following information ready before

you call:

- Product name and serial number

- Description of your peripheral attachments

- Description of your software (operating system, version, appli-

cation software, etc.)

- A complete description of the problem

- The exact wording of any error messages

Packing List

Before setting up the system, check that the items listed below are

included and in good condition. If any item does not accord with the

table, please contact your dealer immediately.

• 1 x PCI-1757UP Card

• 1 x User Manual

• 1 x CD-ROM

• 1 x Normal Profile Replacement Bracket

Safety Precaution - Static Electricity

Follow these simple precautions to protect yourself from harm and the

products from damage.

1. To avoid electrical shock, always disconnect the power from your

PC chassis before you work on it. Don't touch any components on

the CPU card or other cards while the PC is on.

2. Disconnect power before making any configuration changes. The

sudden rush of power as you connect a jumper or install a card may

damage sensitive electronic components.

PCI-1757UP User Manual 2

Chapter 1 General Information

1.1 Introduction

PCI-1757UP is a 24-bit DI/O card with PCI bus. It provides you with 24

bits of parallel digital input/output, and emulates mode 0 of the 8255 PPI

chip, but the buffered circuits offer a higher driving capability than the

8255.

The card emulates one 8255 PPI chips to provide 24 DI/O bits. The I/O

bits are divided into three 8-bit I/O ports: A0, B0 and C0. You can config-

ure each port as either input or output via software. The dual interrupt

handling capability provides users the flexibility to generate interrupts to

a PC. A pin in the connector can output a digital signal simultaneously

with the card's generating an interrupt.

This card uses a DB 25-pin connector for easy and reliable connections to

field devices.

One feature gives PCI-1757UP a practical advantage in an industrial set-

ting. When the system is hot reset (the power is not turned off) the PCI-

1757UP retains the last I/O port settings and output values if the user has

set jumper JP1 to enable this feature. Otherwise, port settings and output

values reset to their safe default state, or to the state determined by other

jumper settings.

1.2 Numbering Convention

All numbers given in this manual are in decimal format unless specifi-

cally noted otherwise. In particular, where a register address is given as

(Base + 32), the decimal number "32" should be added to the base value.
