Ni 9263 default signals on device memory underflow

[JensFu]

Hi

I am working with the 9263 Analogue Voltage Output Module.

There one has to serve the output buffer with data. If this is not done periodically, a buffer underrun error occurs (error code -200621).

Well since we are serving the module from a desktop PC one cannot guarantee what kind of CPU consuming processes the user might runs aside

the main application.

Therefore I am looking for a kind of "fallback or default signal definition" that is outputted when a memory underflow occurs. Default is just a DC value (with the last level).

But i would like to have a sine signal when the memory underrung occurs.

Is this possible somehow to program to the Module itself?

Another option would be if i could set simply the levels of each channel.

Like if my desktop application crashes, and no data is transmitted to the device (and thus a buffer underrun occurs), I want all chanels bo e on 0 Volt.

Hi,

I think this error is related to:

Thanks for the reply, Johannes.

Unfortunately I do not know where the original source files are located...

Is this part of the DaQ driver?

How can i rebuilt them, e.g. where are these project files (Visual Studio?) to rebuild the drivers.

I searched my entire pc, but could not find any of these files (or classes whithin these files)..

Thanks
