Why do I get a timeout error using getdata (data acquisition toolbox)?

I am trying to use the data acquisition toolbox from MATLAB v7.11.0 to get samples off a ADLINK PCIE 2010 DAC card. I can successfully use the getsample command to extract a single sample, but when I try to collect a set of samples at a given sampling rate getdata seems to fail.

Example code and output is shown below - the islogging command suggests the card is working as expected. If I try and use peekdata after the stop command it claims no data exists.

>> set(ai_device,'SampleRate',10)

>> set(ai_device,'SamplesPerTrigger',10)

>> set(ai_device,'SamplesAcquiredFcnCount',10)

>> start(ai_device)

>> islogging(ai_device)

ans =

       1

>> [D,T]=getdata(ai_device,10,'double')

Error event occurred at 11:49:21 for the object: mwadlink0-AI.

A timeout occurred during GETDATA.
