Reading Analog Input using NI 9205 on NI cRIO 9004 with NI cRIO 9104 FPGA chasis

 I am trying to read read Analog Input using NI 9205 on NI cRIO 9004 with NI cRIO 9104 FPGA chasis. The analog input given on Channel 1 (in NRSE mode) is simple DC signal between 0 to 10 V. I am expecting the signal on Ch1 as it is connected on this channel, but in code i am getting same signal on all the channels.

What could be the problem?

I think that you should connect the unused channel to the GND. Because when are unconnected then assume undefined values.

Well, thanks Jorge for ur answeer, it really helped me. But i would like to add a correction note here that not all but only two adjecent channels with the one to which the input is given, should be connected to COM or GND. Because, the adjecent channels picks up the signal from the input channel and it gets passed to all the channels.
