DAQmx Multiple Channel Reading Problem

[meakcey]

Hi,

I have problem about RSE and Differential compact data acquisition.

I am trying to read 17 rse, 20 differential sensor signal at the same time. 

While taking data with DAQmx base tools, even one of differential sensor is acting, other rse and differential signals are also seems acting.

In MAX, we are selecting sensors one by one with suitable configuration and see correct values. If we chose channel 2 as differential, none of changing at the other channels does not seem at selected one. 

All connections are checked with multimeter and MAX as mentioned above.

The only problem seems at DAQmx.

Is there any reported bug or a block diagram mistake which I've added?

Thanks.

Hi

suggest you post the actual vi so that we can havea look.

what channels have you configured as RSE and what have you configured as Differential? when you configured channel 2 as differential is your channel 10 also configured as another channel?

when you meant channel 2, i assumed it as ai2. post the code and the configuration you used.
