PCI-1750 User Manual 2
1.1 Introduction
The PCI-1750 offers 16 isolated digital input channels, 16 isolated digital output
channels, one isolated counter and one timer with PCI bus interface. With isolation
protection of 2500 VD C the PCI-1750 is ideal for industrial 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 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 combination to gen-
erate interrupts to the PC. A user can easily configure the interrupts through soft-
ware.
The PCI-1750 uses a PCI controller to interface the card to the PCI bus. The control-
ler 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.
