Why My NI 8398 Disconnects During Automated Test

Hardware

  • PCIe-8398
  • PXIe-8398

Issue Details

I am using an NI PCIe‑PXIe‑8398 with an Advantech IPC, and the device disconnects when I run an automated test.

Solution

Update the system BIOS settings by disabling ACPI (Advanced Configuration and Power Interface). This change should be made directly in the BIOS setup of the Advantech IPC, following the manufacturer’s guidance.
 
After disabling ACPI, save the changes and reboot the system. Once the system restarts, rerun the automated test to confirm that the disconnection no longer occurs.

Additional Information

If the issue persists, check with the hardware manufacturer to ensure the BIOS version and settings are fully compatible with the NI 8398 card.
