Hi Nuri,
You code looks fine on the surface and this should indeed work with no issues. Since you are using channel #2 as input, can I double-check that you tried setting that on the object? You can use either of
deviceReader.NumChannels = 2;
or
deviceReader.ChannelMapping = 2;
The first will return a Nx2 matrix, the second only a N-long column vector if you keep NumChannels equal to 1. Please let us know how this goes.
Good luck!
Gabriele.
