There are 1 K samples FIFO for A/D (AI) on PCI-1718HDU/HGU. This

is an important feature for faster data transfer and more predictable per-

formance under Windows system.

Onboard Programmable Timer/Counter

PCI-1718HDU/HGU provides a programmable timer counter for generat-

ing pacer trigger for the A/D conversion. The timer/counter chip is

82C54, which includes three 16-bit counters of 10 MHz clock. One

counter is used as an event counter for counting events coming from the

input channel. The other two are cascaded together to make a 32-bit timer

for pacer trigger time base.

BoardID Switch

PCI-1718HDU/HGU has a built-in DIP switch that helps define each

card’s ID when multiple PCI-1718HDU/HGU cards have been installed

on the same PC chassis. The BoardID setting function is very useful when

building a system with multiple PCI-1718 cards. With the correct Boar-

dID settings, you can easily identify and access each card during hard-

ware configuration and software programming.
