How to set the source pin of the counter

[nangroy]

I am programming using PCI-6251 DAQ card with the board BNC2110 and Labview 7.1.

I just want to write a program to count the frequencies of two signals from outside. In Measurement and Automation, I could use the edge counting by selecting the edge source as Dev1/PFI0 etc. But in vi window, how to modify the source pin of ctr0 to say PFI0 or PFI1 or other else?

And also is the strategy of my program correct or not? Because later I want to use one internal counter to count for my external signal frequencies.

Use the channel property node and specify the input terminal for the counter.

Thanks Adnan Z.

One more basic question

I want to apply the strategy of the example given below for my frequency measurement. However I am not able to open the file since my Labview version is 7.1. Thus, would anyone help me to save it as labview 7.1 or lower, or just leave a screen shot here. Thanks

Hey Nangroy,

Here's that file in LV 7.1 with DAQmx 8.8.  If you have an older version of the driver some of your subVIs may need to be changed.
