NI5124 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: Image "Briton_0.png"


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



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)



11.   Error code -1074108967 occurred at an unidentified location

12.   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.


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!


What could be my next step?

Thanks in advance



PS: I also posted the question in NI-forum, but none has responded yet and then I think the hard core fellows at LAVAG could help me ;)
