Hi,
I am trying to read my linear encoder by USB-6211. My A and B signals are sinuous signals between +/- 50mV. I want to use the linear encoder task of Daqmx to count the distance I moved, but it doesn't work. Is any requirement for the linear encoder task od Daqmx?
Thanks.

Is it possible I set a threshold value to build an internal counter? Do you have similar programs?
My sensor is an optical encoder. It generate two sinuous signals within pi/2 phase difference.
Thanks.

I mean since I already got the sinuous signals between +/- 50mV by DAQ. All I want is to count the peak numbes of these signals. So could I set a threshold value to build up a counter by while loop? That will not go through the DAQassistant but write a LabView counter directly.Do you have simular examples?
Thanks.
