PCI-1718 Series User Manual 2

Chapter 1 Introduction

Thank you for buying the Advantech PCI-1718HDU/HGU. PCI-

1718HDU/HGU is a PCI-Bus multifunction 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

• Timer/counter.

A programmable-gain instrument amplifier lets you acquire different

input signals without external signal conditioning. An onboard 1 K word

FIFO buffer provides high-speed data transfer and predictable perfor-

mance under Windows. Automatic channel scanning circuitry and

onboard SRAM let you perform multiple-channel A/D conversion with

DMA and individual gains for each channel.

PCI-1718HDU/HGU is compatible* with its ISA-Bus predecessor, the

PCL-818HD/HG. This puts rich software support and a wide variety of

external signal conditioning boards at your disposal.

The following sections of this chapter will provide further information

about features of the multifunction cards, a Quick Start for installation,

together with some brief information on software and accessories for the

PCI-1718 cards.

Note*

1. PCI-1718HDU/HGU is register-level- pro-

gramming compatible with PCL-818HD/HG

2. Due to the difference between ISA and PCI

architecture, we use “interrupt + FIFO” to emu-

late the DMA function. But it makes no differ-

ence to your programming and applications.
