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.
