PXI-NI-5124 error code -50550

NI-5124 PXI oscilloscope failing.


  1. It’s placed in a system that has run for 20 years on Windows XP and Labview 8.2.1
  2. PXI rack 1045
  3. Mxi: PXI-MXI-4 (PCI-8336 and PXI-8336)
  4. Now the PC is upgraded to a new one with Windows 10 and LV15.
  5. After new PC the system started, I can see all cards in PXI rack in MAX
  6. I can communicate with all card but not NI5124 Scope.
  7. When I try to launch Testpanels for Ni5124 I got the following error:


  8. I can launch Testpanels when I point at NI4070 DMM in MAX.
    I can then open a new fan and choose OscilloscopeBriton_1-1632293397564.png


  9. When pressing Run/Stop I got this error:


  10. NI MAX pictures:


MAX can´t recognize the type of the PXI bridge, but it is a PXI-MXI-4 (PCI-8336 and PXI-8336)








  1. Error code -1074108967 occurred at an unidentified location

  2. I have looked for solution at NI for error -50550 and found this:


These error codes indicate fairly general problems that can be caused by either hardware or software. You can resolve these errors through one of the troubleshooting steps below:

  1. Reset the device in Measurement & Automation Explorer, then try the self-calibrate again.
  2. Reboot the PC or PXI controller.
  3. Try a different PCI or PXI slot.
  4. If you are using a remote controller (i.e PCIe-8361) make sure the MXI card has the DIP Switch in the correct position, either ON if you are using BIOS Compatibility Mode or OFF if you are not.

I have tried 1, 2 and 3 => did not help. About 1 Reset and Self-test is success but Self- Calibrate is just running for ever.
@4 If this was not setup correctly, I assume the PC would not be able to see the PXI rack and modules in it.



What could be my next step?

Tanks in advance

Update: I have tried to delete all labview and device driver Sw on the PC and then installed it again.
I still got the same error!

From the error it seems you may have compatibility issues. Have you checked your system for that?

Sorry the late response.
I have been spoken to a NI engineer and it looks like combability problem with the MXI card. It's not supporting Win10.
I have ordered new MXI card and I'll went back when I get the new card and I know it has solved the problem. Hopefully ultimo November.
