Experimental Physics and Industrial Control System

I am trying to transfer pixel values from an Area Detector driver's private variable into an NDArray for viewing with ImageJ.  I have verified that the ImageJ plugin works.  I have also verified that the test data are generated correctly.  My code follows that of the Mythen driver, except with two dimensions instead of one.  I alloc() an NDArray and copy the pixel values over.  I have verified that the pixel values are transferred correctly to the pImage.  I note there are no NDArrayCallbacks.  When I look at $(P)$(R)ArrayData, it appears to be all zeroes except the first value, which appears to increment on both acquisition and "caget $(P)$(R)ArrayData".  What might I be missing?

Thank you,

Iain.
