Thanks Kay. That worked. I can now get the NTNDArray. I still have to use wrapUnsafe rather than wrap, ...but it works.

Another mystery:
When I call myarray.getValue() it returns a PVUnion. somehow the PVUnion knows that the data is ushort[] uint[] or whatever type the image data is.
How do we ask the PVUnion what data type it is? In Eclipse I can trap on the code and see it is ushort, for my array, which is correct. But I cannot figure out
how my own code would know it i ushort. It must be the introspection interface? I have been mucking with with this....
I guess I use the convert utility to convert to a real Java tupe like int[]. But I have to know which Java type to use....

Thanks
Tim

> Not sure how to request the entire normative type on pvget.

Try "field()" as the request to get all fields:

   pvget -r "field()" ...

Same when you assemble request in Java:

  PVStructure read_request = CreateRequest.create().createRequest("field()");
  ... channel.createMonitor(.., read_request);
