Issue Details

I installed the new LabVIEW Plug and Play driver for my Avionics Interface Technologies (AIT) 429 or 1553 board and I need to update the Firmware on boards.


​If you have a Windows based PC or controller, follow these instructions to update the firmware of your card:
  1. Run C:\Program Files\AIT\[LATEST AIT DRIVER]\Visa Drivers\utils\update_firmware.bat
  2. You will see two options. Select option b and you will see stars going across the bottom of the window. Updating takes about 15 minutes.
  3. Once completed, completely power off then power on your system. A reset is not sufficient.
A second way to update the firmware is to navigate to C:\Program Files\National Instruments\LabVIEW 20xx\project\AIT [protocol] Utilities and run AIT [protocol] Update

If you only have a LabVIEW Real-Time based PXI controller, please contact National Instruments Support for assistance in upgrading your firmware.

Additional Information

With every new driver installed, it is recommended to update the firmware of your card. To download the last driver, please visit AIT's website linked below.
