DIO port config using NI USB-6501

[Troy12]

Hi,

I have a question about configuring USB DAQ 6501.  Till date, we have used PCI DAQ 6023E and have drivers written in LabVIEW to configure it.  We use the DAQ for trigger purpose only.

To achieve more flexibilty, we are trying to use NI USB-6501 with the same drivers.  With MAX, test panel can be opened and USB-6501 can be controlled.  However, DIO port config.vi (VI that comes with LV) does not work and everytime  error code: -10401 is obtained.  Description of -10401 is - "The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using MAX."   How do I resolve this issue?

I don't have much experience with DAQmx and was wondering if backward compatability with Traditional (legacy) DAQ was the issue.  If it is indeed the problem, then is it possible to write LabVIEW code to work with PCI-DAQ and USB-DAQ??  

SW Version used:

LabVIEW 8.0.1 and DAQmx 8.1

Any response is appreciated. Thanks!

Hi Troy12,

Thank you very much for the software version detail.
Indeed, the 6501 is only supported under DAQmx while your previous card (6023E) was supported with both.
You can use the same DAQmx code with both cards. DAQmx is much more intuitive and fast to program simple applications. There a great new documentation in this link that will guide you from very basic programming to very common and advance tools.

Thanks Yardov!

We also have few PCI-6503 DAQ cards. Will there be a compatibility issue for these card with DAQmx?

Thank you!

Hi Troy12,

According to the DAQmx readme file, the 6503 is supported under DAQmx and therefore you will be able to use the same API.
Good Luck,
