Introduction

The PCIE-1753 is a 96-ch DI/O card with PCI Express bus. It provides 96 channel of
parallel digital input/output compatible with 5V/TTL. It emulates mode 0 of the 8255
PPI chip, but the buffered circuits offer a higher driving capability than the 8255.
The I/O channels are divided into twelve 8-bit ports. Each port can be divided into two
nibbles (bit 0 ~ 3 belongs to low nibble, while bit 4 ~ 7 belongs to high nibble). You
can configure each nibble as either input or output via software. The interrupt han-
dling capability provides users the flexibility to generate interrupts to a PC. This card
uses a high density SCSI 100-pin connector for easy and reliable connections to field
devices.
Two other features give the PCIE-1753 practical advantages in an industrial setting.
When the system is hot reset (the power is not turned off) PCIE-1753 retains the last
I/O port settings and output values if the user has set jumper JP1 to enable this fea-
ture. Otherwise, port settings and output values reset to their default state, or to the
state determined by other jumper settings. The PCIE-1753's other useful feature is it
supports both wet and dry contacts for digital input channels, allowing it to interface
with other devices more easily.
The following sections of this chapter will provide further information about features,
installation guide, and some brief information on software and accessories for the
PCIE-1753 card.

The Advantech PCIE-1753 offers the following main features:
Plug-and-Play Function
The PCIE-1753 is a Plug-and-Play device, which fully complies with PCI Express
Specification Rev V1.0. During card installation, there is no need to set jumpers or
DIP switches. Instead, all bus-related configurations such as base I/O address and
interrupt are automatically done by the Plug-and-Play function.
Board ID
The PCIE-1753 has a built-in DIP Switch that helps define each card's ID when multi-
ple PCIE-1753 cards have been installed on the same PC chassis. The board ID set-
ting function is very useful when users build their system with multiple PCIE-1753
cards. With correct Board ID settings, you can easily identify and access each card
during hardware configuration and software programming.
