To use a National Instruments or Measurement Computing board
1. Download and install the hardware driver from the vendor’s website.
2. During the Embed installation, you must:
a. Under the Select Modules window, activate the Real-Time Analog/Digital I/O option.
b. Under the Ready to Install window, activate the appropriate Measurement Computing, National Instruments, and VisSim legacy driver options.
Note: If you did not install the National Instruments NIDAQmx driver from the vendor website, but you did activate the National Instruments NIDAQmx driver option in the Ready to Install window, you will receive Error 126 about a missing National Instruments DLL each time you start Embed.
If you want to use an NIDAQmx block, you must install the hardware driver from the National Instruments website; you do not, however, have to re-install Embed. If, on the other hand, you are not ready to use a NIDAQmx block and do not want to see this error message each time you start Embed, go to Edit > Preferences > Addons and delete NATINST.DLL and/or NATINSTMX.DLL.
