Cannot read digital waveform on NI USB-6001

Solved!
Go to solution

Trying to perform digital waveform reading on digital input on NI USB-6001, Sample Clock give me error -200077, see picture below.

Analog waveform reading is OK, see the same picture. Single digital read is also OK, when Sample Clock is removed.
What is the problem? USB-6001 does not support timing for digital inputs reading? Or I am doing something wrong?

USB-6001 is a low-cost DAQ and it does not support HW timed Digital input or output.
