Brett, I looked at the specs for the datataker dt50 and I noticed that it has a serial port interface. You may be able to send commands to the dt50 from LabVIEW and the dt50 may respond with data. You will need to get the command set from datataker. Here are some links to tutorials that explain getting started with serial programming:
