Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products 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 installation. 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 testing, 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 outof-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 on screen 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 proof of the purchase date

Safety Precaution - Static Electricity
DISCLAIMER: This set of instructions is given according to IEC 704-1. Advantech
disclaims all responsibility for the accuracy of any statements contained
herein.Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
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.
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.

1 Overview
1.1 Introduction
The PCI-1750 offers 16 isolated digital input channels, 16 isolated digital output
channels, one isolated counter and one timer with PCI bus interface. With isolation
protection of 2500 VD C the PCI-1750 is ideal for industrial applications where highvoltage protection is required.
The card's 16 bits are divided into two 8-bit I/O ports. This makes the PCI-1750 very
easy to program. This card also offers dual interrupt handling capability, providing the
user more flexibility in using the counter, timer, digital inputs or a combination to generate interrupts to the PC. A user can easily configure the interrupts through software.
The PCI-1750 uses a PCI controller to interface the card to the PCI bus. The controller fully implements the PCI bus specification Rev 2.1. All bus relative configurations,
such as base addresses and interrupt assignments, are automatically controlled by
software.
1.2 Features
16 isolated digital input and 16 isolated digital output channels.
High voltage isolation on all channels (2500 V
High sink current on isolated output channels (200 mA/Channel).
D-type 37-pin female connector.
Supports dry contact or 5 to 50 V
