PCI6229 Multifunction DAQ - AI Channel interference

[MogaRaghu]

This is a new PCI-6229 card and has a peculiar issue. With all AI channels left floating just connected the 5V signal from the screw terminal board to AI5 input. I could see that the signal is picked up by all other channels almost at 4V level. 

I do understand that floating channels pick up stray signals and the SH amplifier can pass on some of the previous channel value during multiplexing to the next channel. But in this case the interference is so high that even valid signals are modified and I am getting wrong values. The source impedance of all connected devices is very low ( about 1KOhm or less ) as they are I-V signal conditioners. 

IS the card gone for good ?
