Configuring prescaling is very similar in DAQmx and Traditional DAQ. First we configure the counter for simple edge counting. We configure the counter, initial count, count direction and edge. We then use a DAQmx Channel Property Node to specify the prescaler value. There are three valid values: 1, 2 and 8. We then start the task and within the loop retrieve the current count. Just like in traditional DAQ this value has not been scaled. To determine the actual count you would need to multiply it by the prescaler you selected.
Steps:
1. Create a Counter Input channel to Count Events. The Edge parameter is used to determine if the counter will increment on rising or falling edges.
2. Configure the pre-scaling.
3. Call the Start VI to arm the counter and begin counting. The counter will be preloaded with the Initial Count.
4. The counter will be continually polled until the Stop button is pressed on the front panel.
5. Call the Clear Task VI to clear the Task.
6. Use the popup dialog box to display an error if any.
