How do I allocate shared host memory on the PXI-8176?

[broskyar]

I am using LabVIEW and NI-VISA to write a driver for a serial communications card. I want to set up shared memory on the NI-8176 PXI controller running Windows 2000. I know that I must allocate the memory using Windows and possibly MAX before I perform the necessary steps with the LabVIEW NI-VISA. How do I do this?

Shared memory is only supported with VXI. If you are communicating with a third party PXI or PCI card using VISA, you will use viIn, viOut, and viMove functions to transfer data accross the PCI bus. For more information, I recommend you review the tutorial "Using the PXI Driver Development Wizard and NI-VISA to Register-Level Program a PXI/PCI Device under Windows" at
