Short Name: CI.Prescaler

Property of DAQmx Channel

Specifies the divisor to apply to the signal you connect to the counter source terminal. Scaled data that you read takes this setting into account. You should use a prescaler only when you connect an external signal to the counter source terminal and when that signal has a higher frequency than the fastest onboard timebase. Setting this value disables duplicate count prevention unless you explicitly set CI.DupCountPrevention to TRUE.
