Introduction

The PCI-1750/PCI-1750SO offers 16 isolated digital input channels, 16 isolated digi-
tal output channels, one isolated counter and one timer with PCI bus interface. With
isolation protection of 2500 V
applications where high-voltage protection is required.
The card's 16 bits are divided into two 8-bit I/O ports. This makes the PCI-1750/PCI-
1750SO very easy to program. This card also offers dual interrupt handling capability,
providing the user more flexibility in using the counter, timer, digital inputs or a combi-
nation to generate interrupts to the PC. A user can easily configure the interrupts
through software.
The PCI-1750/PCI-1750SO uses a PCI controller to interface the card to the PCI bus.
The controller fully implements the PCI bus specification Rev 2.1. All bus relative
configurations, such as base addresses and interrupt assignments, are automatically
controlled by software.
