PCI-1711U Series User Manual 4

Onboard Programmable Timer/Counter

PCI-1711U/UL provides a programmable timer counter for generating

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 chan-

nel. The other two are cascaded together to make a 32-bit timer for pacer

trigger time base.

BoardID Switch

PCI-1711U/UL has a built-in DIP switch that helps define each card’s ID

when multiple PCI-1711U/UL cards have been installed on the same PC

chassis. The BoardID setting function is very useful when building a sys-

tem with multiple PCI-1711U cards. With the correct BoardID settings,

you can easily identify and access each card during hardware configura-

tion and software programming.
