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.

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.

General Information
This chapter introduces PCI-1757UP
and provides detailed specifications.
Sections include:
• Introduction
• Numbering Convention
• Features
• Specifications

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.

Chapter 2 Installation
2.1 Initial Inspection
Before starting to install PCI-1757UP, make sure there is no visible dam-
age on the card. We carefully inspected the card both mechanically and
electrically before shipment. It should be free of marks and in perfect
order on receipt.
As you unpack PCI-1757UP, check for signs of shipping damage (dam-
aged box, scratches, dents, etc.) If it is damaged or fails to meet its speci-
fications, notify our service department or your local sales representative
immediately. Also, call the carrier immediately and retain the shipping
carton and packing materials for inspection by the carrier. We will then
make arrangements to repair or replace the unit.
2.2 Unpacking
PCI-1757UP contains components that are sensitive and vulnerable to
static electricity. Discharge any static electricity on your body to ground
by touching the back of the system unit (grounded metal) before you
touch the board.
Remove the PCI-1757UP card from its protective packaging by grasping
the card's rear panel. Handle the card only by its edges to avoid static dis-
charge which could damage its integrated circuits. Keep the antistatic
package. Whenever you remove the card from the PC, please store the
card in this package for its protection.
You should also avoid contact with materials that hold static electricity
such as plastic, vinyl and styrofoam. Check the product contents inside
the packing. There should be one card, one CD-ROM, an extra bracket
and this manual. Make sure nothing is missing.
2.3 Jumper & Switch Settings
We designed PCI-1757UP with ease-of-use in mind. It is a Plug & Play
card, i.e. the system BIOS assigns the system resources such as base
address and interrupt automatically. The following section describes how
to configure the card. You may want to refer to the figure below for help
in identifying card components.

2.3.1 Setting the BoardID Switch (SW1)
This section describes how to set the BoardID switch of PCI-1757UP.

unique identifier to the card.

11 Chapter2
PCI-1757UP emulates one 8255 programmable peripheral interface (PPI)
chip in mode 0, but with higher driving capability than a standard 8255
chip. Each of the 8255 chips has 24 programmable I/O pins that are
divided into two 8-bit ports and two 4-bit ports, designated PA, PB PCL
and PCH.
Each port can be programmed as an input or an output port. You can set
the corresponding ports to be configurable as input or output ports by
switch SW2 or software. When “IO CF.” position is “ON”, set the ports
to be input or output ports by the software. Else, when “IO CF.” position
is “Off”, you can set the ports by the switch SW2 directly. The position
setting is “ON”, the corresponding port is input port; else position is
“OFF”, the corresponding port is output port.
2.3.3 Output Signal at Hot Reset Setting (JP1)
As shown below, JP1 is used to set the output signal after a hot reset.
Table 2.3: Hot Reset Mode Setting
JP1 Output Signals Status after Hot Reset
Hot Reset Output Memory.
Remember the last output signals and I/O
settings before reset and keep these val-
ues on power up.
Default Output Setting
Clear the I/O configuration to default if hot
reset.
Note The reset must be a "hot" reset (power not dis-
connected) for enabled JP1 to return ports to
their prior values. Otherwise, the card behaves
as though JP1 was not enabled.

2.5 Installation Instructions
PCI-1757UP can be installed in any PCI slot of the computer. However,
refer to the computer user's manual to avoid any mistakes and danger
before you follow the installation procedure below:
1. Turn off your computer and any accessories connected to the com-
puter.
2. Disconnect the power cord and any other cables from the back of
the computer.
3. Remove the cover of the computer.
4. Select an empty PCI slot. Remove the screw that secures the expan-
sion slot cover to the system unit. Save the screw to secure the
interface card with the retaining bracket.
5. Carefully grasp the upper edge of PCI-1757UP. Align the hole in
the retaining bracket with the hole on the expansion slot and align
the gold striped edge connector with the expansion slot socket.
Press the card into the socket gently but firmly. Make sure the card
fits the slot tightly.
6. Secure PCI-1757UP by screwing the mounting bracket to the back
panel of the computer.
7. Attach any accessories (25-pin cable, wiring terminal, etc.) to the
card.
8. Replace the cover of your computer. Connect the cables you
removed in step 2.
9. Turn the computer on.
Warning! TURN OFF your computer power supply when-
ever you install or remove any card, or discon-
nect cables.
