On-board Programmable Counter
The PCI-1710/1710HG provides a programmable counter for generat-
ing a pacer trigger for the A/D conversion. The counter chip is an
82C54 or equivalent, which includes three 16-bit counters on a 10
MHz clock. One counter is used as an event counter for counting
events coming from the input channels. The other two are cascaded
together to make a 32-bit timer for a pacer trigger.
