ground problem for daq card

[RPKumar]

I am using daq card PCI-MIO-16E1.It was working fine in one PC.When transferred to another PC, there is some ground problem it seems.when no signal is connected, it is showing a voltage level of -5v and when a signal is connected gradually it rises ffrom this level and reaches the level of the signal.whereas in the old PC a level of about 0.1v was seen.this is irrespective of the configuration(differential,RSE,NRSE etc).can anybody help ?

How does the 6070E (PCI-MIO-16E-1) perform if you put it back in the original system or yet another one?  Have you tried multiple channels? 

Do you notice a difference in the keying of the PCI connector between the two motherboards?  The 6070E is a 3.3V 32-Bit card and will not work with a 5V 32/64-Bit slot even though it will fit.  Consult the following document for more details on PCI keying: PCI Keying and Voltage Compatability
