PCI-1751 48-ch Digital I/O and 2-ch Counter PCI Card Features 48 TTL digital I/O lines Emulates mode 0 of 8255 PPI Buffered circuits for higher driving capacity than the 8255 Interrupt handling Timer/Counter interrupt capability Supports both dry and wet contact Keeps the I/O port setting and DO state after system reset BoardID switch RoHS COMPLIANT 2002/95/EC 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.
