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.

Chapter 1 Overview
1.1 Introduction
Thank you for buying the Advantech PCL-818HD/HG/L. The PCL-
818HD/HG/L is a high-performance multifunction data acquisition card
for IBM PC/XT/AT or compatible computers. It offers the five most
desired measurement and control functions: 12-bit A/D conversion, D/A
conversion, digital input, digital output and timer/counter.
A programmable-gain instrument amplifier (x 0.5, 1, 2, 4 and 8) lets you
acquire different input signals without external signal conditioning. An
onboard 1 K word FIFO buffer provides high-speed data transfer and pre-
dictable performance under Windows.
Automatic channel scanning circuitry and on-board SRAM let you per-
form multiple-channel A/D conversion with DMA and individual gains
for each channel.
The PCL-818HD uses a CPLD chip designed in-house by Advantech
engineers. This single chip integrates most of the card's functions, giving
you maximum accuracy and reliability, along with minimum cost, size
and power consumption.
The PCL-818HD is hardware and software compatible with its popular
predecessor, the PCL-8l8HG. This puts rich software support and a wide
variety of external signal conditioning boards at your disposal.
Note: AI data acquisition in DMA mode is only recommended
when using an Intel Pentium 3 motherboard. It will not
function properly on a Pentium 4 motherboard or above.
