Hello Rachel,
Thank you for contacting National Instruments.
It is difficult to say what is causing this problem. The first thing
I would suggest is upgrading to the most current version of NI-DAQ
that is supported by your card and by your operating system. The most
current driver that supports your card is NI-DAQ 6.9.3. You can find
this driver using the following link:
http://digital.ni.com/softlib.nsf/websearch/50F49E43A22C0D2186256BF3006B9A96?opendocument&node=132070_US
After you update your driver, you will be able to test your card
closer to the hardware level using Measurement and Automation Explorer
(MAX). Once you open up MAX, expand the Devices and Interfaces tree.
Under Traditional NI-DAQ Devices, right click your card and select
test panels.
You will be able to perform basic analog input and
output from the test panel and determine if your card is functioning
correctly.
If you are still having a problem, if possible, try increasing the
buffer size within your ADE (in this case, TurboView). For more
information on memory allocating functions, refer to the documentation
for your ADE.
I hope this helps! Let me know if you have further questions.
