8133 drivers

[J_O_E1]

Hello,

My device manager on my pxi 8133 indicates I'm missing a driver.  Does anyone have any ideas if I should care?

Hello Anthony, 

Do you know which device is unidentified? If you cannot see all of your modules in Measurement and Automation explorer, you need to install the driver for the missing module. 

If you can determine which device is causing the problem, we can determine if it needs to be fixed and how to do it.

Was this ever resolved? I'm having a similar issue on my PXIe-8133. It is not related to a PXI module since when there is nothing in the chassis I still have those two items (Intel QM57) as drivers not installed.

I suspect those are the two devices are the onboard watchdog and trigger router.  They exist on the PXI controller but are only used in LabVIEW Real-Time operating systems, so under Windows it's safe to ignore the missing devices.  On our Windows installation media, we provide two small "stub drivers" that hide those devices under Windows, just so you don't see the yellow exclamation and wonder what's wrong (because nothing is wrong).

If you installed Windows through some other means, then you would not have those automatically have those drivers available.  To fix those missing device entries, follow the instructions in this similar post here.

Cheers,

Hey Tim,

I found that another customer had a Code 28 problem on a USB-6251. The culprit was the USB cable. Too bad this doesn't apply with this case. I would also install the PXI Platform Services and check which version you should install depending on your chassis.

Also, try to delete the devices from the device manager (check to delete the driver, as well) and re-detect it.

If that doesn't work, there is always the possibility that it's the NI Watchdog and Trigger Router functions of the controller that are not supported in Windows, only in LabVIEW Real-Time, like Josh mentions in this thread.

Hope this helps.

Thanks Josh,

I did the windows install, so it all makes sense.  Thanks for the help.
