I have a USB-8451 on order but it hasn't arrived yet. I went ahead and downloaded and installed the driver software, NI-845x 2.0. I am running LV 2012 (12.0.1f5 32-bit) and I didn't see any options for 2012 support in the installer, so I clicked the LV 2011 support and installed that. That seems to have created one LLB file, ni845x.llb.
I searched for examples using the 8451 but didnt' find any (i.e. "Help --> Find examples" in LV 2012). I searched NI support online and found SPI Execute Read of Shift Register.vi. When I open it and point to the llb file to resolve references, the VI is broken. All the sub-VIs are not executable. The errors are 1) call lib. fcn. note contains unwired or bad terminal, 2) invalid refnum class, and 3) you have connected two terminals of different types.
Why are these broken? Does it have anything to do with the USB-8451 not actually being hooked up to my computer?

I would download a more recent version of the driver - NI-845x 2.1.2 (https://www.ni.com/en/support/downloads/drivers/download.ni-845x-driver-software.html) is the most recent.

Thanks - this worked and the VIs are runnable. The official support page for the 8451, https://www.ni.com/en-us/support/model.usb-8451.html, only shows up to version 2.0, so I guess NI needs to update it.

Thanks for the information. I will have someone look into it.

Bump.
Looks like the web-site update is not done yet. I faced a similar issue today, and landed on this page while doing an internet search.
Thanks for the link. (Trust 2.1.2 is still the latest version...)

Hi Vishak,
It may take some time for this to get fixed. I have resubmitted the request to have it fixed.
2.1.2 is still the latest version of the driver. For future reference, the best place to find the most recent version of our drivers is at ni.com/drivers.

Thank you, Catherine.
