PCIE-1751 User Manual 2
1.1 Introduction
The PCIE-1751 is a 48-ch DI/O and 3-ch counter card with a Universal PCI Express
bus. It provides 48 channels of parallel digital input/output compatible with 5V/TTL as
well as 3 counters. It emulates mode 0 of the 8255 PPI chip, but the buffered circuits
offer a higher driving capability than the 8255.
The card emulates two 8255 PPI chips to provide 48 DI/O channels. The I/O chan-
nels are divided into six 8-bit ports. Each port can be divided into two nibbles (bits 0 ~
3 belong to the low nibble, while bits 4 ~ 7 belong to the high nibble). You can config-
ure each nibble as either input or output via software. The dual interrupt handling
capability provides users the flexibility to generate interrupts to a PC. A pin on the
connector can output a digital signal simultaneously as the card generates an inter-
rupt. This card uses a high-density SCSI 68-pin connector for easy and reliable con-
nection to field devices.
Two other features give the PCIE-1751 practical advantages in an industrial setting.
When the system is hot reset (the power is not turned off) PCIE-1751 retains the last
I/O port settings and output values if the user has set the JP1 jumper to enable this
feature. Otherwise, port settings and output values reset to their safe default state, or
to the state determined by other jumper settings. The PCIE-1751’s other useful fea-
ture is it supports both wet and dry contacts, allowing it to interface with other devices
more easily.
The following sections of this chapter will provide further information about features
and the installation guide, together with some brief information on software and
accessories for the PCIE-1751 card.

The Advantech PCIE-1751 offers the following main features:
Plug-and-Play Function
The PCIE-1751 is a Plug-and-Play device, which fully complies with PCI Express
specifications. 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 inter-
rupt are automatically done by the Plug-and-Play function.
Board ID
The PCIE-1751 has a built-in DIP switch that helps define each card’s ID when multi-
ple PCIE-1751 cards have been installed on the same PC chassis. The Board ID set-
ting function is very useful when users build their systems with multiple PCIE-1751
cards. With correct Board ID settings, you can easily identify and access each card
during hardware configuration and software programming.
