    ❑ Read Me First: Safety and Radio-Frequency Interference 4. Installing the Software National Instruments switch modules are packaged with NI-DAQ 7.x driver software which contains three drivers each with a corresponding API—NI-SWITCH, NI-DAQmx, and Traditional NI-DAQ. Each API has an extensive library of functions and VIs that you can call from your application software, such as LabVIEW or LabWindows/CVI, to program your NI switch module.
  • Page 6 Uninstall Earlier Versions of NI-DAQ If you are upgrading to NI-DAQ 7.x from a previous version, uninstall the earlier version of NI-DAQ now. Some NI-DAQ devices supported in 6.9.3 may no longer be supported. Before uninstalling NI-DAQ 6.9.3 or earlier, refer to the DAQ Quick Start Guide, available on the NI-DAQ 7.x Device Documentation CD, for devices no longer supported.
