DAQ, Graphing and Saving to File from 3 E-Series-Devices

[Shadow]

I would like to write and read analog data and save the readed data to file, from 3 E-Series-Devices at the same time in the same computer. This should be take at a frequency from only 100Hz.

Why I always get the error message 10805.
I have a buffered DAQ.
I write to 2 analog Outputs and read 6 analog Inputs at every device.
The buffer is 1000 samples, the sample rate is 100
and I read the buffers twice a second.
After 1 second comes the error.

I am confused and thanks for assistance.

Are you using an external clock? If you are then noise on the clock line can cause this error.
