change the output voltage of digital pins

[L.K]

Hi,
  I am using DAQmxSetDigitalLogicFamilyPowerUpState function to set the digital logic family voltage to 3.3V.

I am calling the function DAQmxSetDigitalLogicFamilyPowerUpState("Dev1", DAQmx_3.3);

But its returning the error number -200452.

Can any one help to solve this issue???.

Actually I want to change the output voltage of digital pins in PCI6629 from default 5v to 3.3v. Is there any way to acheive this?.

I searched through the producet catalog, and it seems like NI does not sell a PCI-6629.  Did you mean a PCI-6229?

Anyway, error -200452 means setting the digital logic family is not supported by your device.  In this case, it means that the hardware is not capable to change to a digital logic level different from the default of 5V.  So there is no way to achieve what you to do with this PCI board alone without external circuitry.

Hope this anwers your question.

Hi,

   Thanks for the reply.

The PCI card I am using is 6229 and not 6629(Typo error from my end). From your reply it seems that I cannot use the function DAQmxSetDigitalLogicFamilyPowerUpState with PCI 6229.

Can u provide the information regarding which PCI card supports the function DAQmxSetDigitalLogicFamilyPowerUpState?.

I don't believe there is any PCI DIO board within the DAQ product lines that can switch between different digital logic levels.

However we do have board with such functionality within High-Speed DIO family from Modular Instruments product line.  Quick search through ni.com, I found these boards.
