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.
