Introduction
PCI-1751U is a 48-bit digital I/O card for the PCI bus. Its 48 bits are divided into six 8-bit I/O ports and users can configure each port as input or output via software. PCI-1751 also
provides one event counter and two 16-bit timers, which can be cascaded to become a 32-bit timer. PCI-1751 adds a universal PCI interface for 3.3 V compatibility.
