Issue Details

What is the actual sampling rate of NI-9423 (8-Channel Sinking Digital Input Module)? The value mentioned in NI-9423 datasheet is inconsistent, some mentioned it to be 100 µs and others 1 µs. 


The correct maximum sampling rate of NI-9423 is 1 µs as per what mentioned below in the NI-9423 main product page of NI website.
There is an error in NI-9423 datasheet mentioning it to be 100 µs instead of 1 µs which is the correct maximum sampling rate.
