Hello Robin,
Data Translation created the DT-LV Link to communicate with their hardware from LabVIEW. With those drivers, you should get VIs and example programs that you can use to perform data acquisition from your board. In most cases, there are simple AI, AO or DIO VIs that you can call. If you don't have any examples, you can contact Data Translation's support site.
