What does AI_ControlInterface do?

[SammyDee]

Hi,

I am trying to do some data aquisition with our PXI system and have noticed that the signal from one of analogue inputs get on another input when the AI_ControlInterface function in lvdaq.dll is called. Perhaps somebody can tell me what that function does (as a first step) because I wasn't able to find any reference to it in manuals or online..?

Cheers,

Sam


P.S. As background, I am trying to make use of NI's Lock-in Start-up Kit, using our multifunction I/O PXI-6070E.

I am not exactly sure what the AI_ContrlInterface does. Can you expound upon what you are seeing when this function is being called?

AI_ControlInterface is an internal function called by the AI Control VI in the Traditional DAQ LabVIEW API. You can find documentation for this VI in the LabVIEW DAQ online help. AI Control can be used to start, stop, or clear a DAQ Analog Input operation, depending on the operation parameter you pass it.
