SCXI test in MAX errors: "Cannot perform test on chassis at this time"

[MikeAshe@SOAR]

We were attempting to upgrade the computer and LabVIEW portions of an SCXI stand. The old system had NT4 on a PC, running LabVIEW 5.1 and an old version of NI-DAQ. It worked ok. We unplugged the DAQ cable from the DAQ card (PCI-E1 board) in the old PC and connected to the new PC which was running Win2K, SP2, LabVIEW 6.0.2 and NI-DAQ 6.9.1 The E1 board checks out, the SCXI chassis shows up in MAX but auto detect gives a message that the chassis cannot be tested at this time. I tried manually telling MAX what the cards were, but when we went to test teh configuration we kept getting the "no at this time message" We reconnected the old PC and it worked fine. The new systemwon't test. For a temporary fix
I saved the new version of the application software back to LabVIEW 5.0 and then converted to 5.1 and fixed all the messed up stuff (my GUI was tab control based, ugh...) and we installed the new/old/new software on the old PC, which is now running the new software ok.
We'd like to get this straighted out. The new PC has a Celeron 950 Mhz on an Intel D815EGEW motherboard. We're also wondering if anyone has bad experiences with that motherboard.
Thanks in advance,
Mike

There are two things you should try. First, delete the SCXI chassis from MAX and then reinsert it. If this does not work, I would suggest reinstalling MAX. To do this, you will first need to unintstall NI-DAQ from your machine. Use Windows' Add/Remove Programs to do this. Once NI-DAQ is uninstall, reinstall it with the PCI-MIO-16E-1 board out of the computer. Once NI-DAQ is completely installed, place the board back in the computer.

After that, add the SCXI chassis and try to use auto-detect.

Let me know if this does not work.

I have experienced this several times in using max and scxi for data acquisition. It has not been repeatable or predictable, but whenever the "cannot test chassis at this time" has appeared, the only solution is deleting the chassis and reinstalling it via max. This is not an acceptable solution, especially if you have a lot of information programmed through the signal conditioner (ie, scxi 1520), because you must re-select all that information for each card. It seems most suseceptible when loading a new .daq file from max.
