From Friday, April 19th (11:00 PM CDT) through Saturday, April 20th (2:00 PM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.
We appreciate your patience as we improve our online experience.
All of the functions you are looking for can be found in the Vision and Motion » Vision RIO pallette, we expanded this pallette quite a bit with the 2014 release but the functions you are looking for should exist in a few version prior ( I have confirmed they are in 2013).
These are installed with Vision Acquisition Software.
Note that the installer still uses "legacy" naming for the top-level feature. It is called "IMAQ I/O" as the top level feature of the Vision Acquisition installer that includes Vision RIO. Note that this API only will work with Vision RT targets and I/O cards.
