Hello,
I'm using two Measurement computing DAQs, one for input and one for output.
Since I have only one ATD converter on the input DAQ, I have used a method shown in the capture.jpg picture.
When I run the program, I get the following outputs:
- No wire connected to any input: All channels showing same noise pattern, basically the common analog graph shows a nearly single line for all inputs.

- Wire connected to channel 3: I rolled my finger on the wire and got some patterns, but again the patterns for all channels are in a nearly single line

- +5V (actually 4.77) taken from the output DAQ's voltage output channel: Again, all channels show nearly the same voltage of 4.6-4.7

I haven't connected anything to the ground connection, but I'm guessing that's not the problem since the channels shouldn't be affected by a ground.
Any idea why this might happen?
I can only attach 3 images in the post, so I'll attach another picture in the comment below.
