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.
