Archived: Upgrading LabVIEW Applications Using NI-IMAQ for IEEE 1394 to NI-IMAQdx

Image Acquisition (IMAQ)
My LabVIEW application was developed using the NI-IMAQ for IEEE 1394 driver. Since this driver was wrapped into NI-IMAQdx beginning with Vision Acquisition Software 8.2.1, how can I upgrade my application?
There are two possible options for upgrading:
- Keep your code exactly the same
With Vision Acquisition Software 8.2.1 through 8.6, the NI-IMAQ for IEEE 1394 driver is now considered "legacy". However, it will still install and activate with the NI-IMAQdx driver. These VIs can still be found under Vision and Motion»NI-IMAQdx»Legacy in the LabVIEW Functions Palette.
With Vision Acquisition Software 2009 and later: You must download and install the Legacy driver after VAS 2009 has been installed. For more information and the download location please see this KnowledgeBase article. Please be aware that this option will not be available for 64 bit Windows systems and is NOT deployable through Application Builder.
- Upgrade your VIs to NI-IMAQdx
Most of the VIs from NI-IMAQ for IEEE 1394 are a 1-to-1 replacement in NI-IMAQdx. These VIs can be replaced with the corresponding VIs from NI-IMAQdx to fully take advantage of the new API.
Any problems that are encountered with the NI-IMAQ for IEEE 1394 will not be updated by NI R&D. Also, the functionalities of the NI-IMAQdx driver will not be available through the legacy VIs. In order to fully take advantage of the NI-IMAQdx driver, the legacy VIs will need to be replaced with the IMAQdx VIs.
