Waveform output problem

[1170]

I am using DAQ6014 to do waveform output. But there is a problem that, when I use buffer to store output voltage and then output through DAQ card, sometimes, the card gives out an err----the buffer can not transfer the data to the card as fast as card output these data, this means that sometimes the card has no data to output, because the computer transfering the data from buffer to card can not keep up with the speed that card output outside.
Did anybody meet this problem before? Could someone has some ways to solve it or give me some advice?

thank you very much

What error code are you receiving? It sounds like probably error -10843. Check out the document linked below. One thing to check is to make sure you are using a DMA for the analog output operation. You can do this by using the Set DAQ Device Information VI in LabVIEW or the Set_DAQ_Device_Info NI-DAQ function call.

I hope this helps.
