PXI-8431

[JSTERN]

Has anyone been successful in getting any PXI-8431 variant working in Linux or would like to try?

Disregarding that nobody ever responded to https://forums.ni.com/t5/Linux-Users/PXI-8431-4-installation-on-Linux/gpm-p/3407591 from two and a half years ago, I would like to get the PXI-8431/2 working.

According to this document, RS-485 support is not ruled out:

USING PCI SERIAL WITH LINUX

https://www.ni.com/docs/en-US/bundle/322539a/resource/322539a.pdf

However, as in the post referenced, the PXI-8431/2 lists no I/O port addresses, only one memory range in region 0 via lspci.  Has anyone uncovered any I/O port addresses?

I am using Ubuntu 14.04 with kernel 4.4.0-64-generic, as this is all that I am allowed to use in my work environment currently.

Hi JStern,

Have you seen this tutorial?

It seems like the main limitation will be driver support, and as far as I know Ubuntu is unsupported. Have you been able to install NI Serial or NI VISA?

So, NI-VISA 16.0 and DAQmx 15.0 are both installed, giving a VISA address to our DAQ card. The NI-Serial package for Linux (1.0, circa 1999) is identical to the package referenced in Using PCI Serial with Linux (also circa 1999), as I referenced in my original post: the included code only works if the serial device has an I/O port address already available in the operating system.

You are correct that the main limitation is driver support; this is why I ended up on the forum after several NI service requests.

You can see the Linux NI Serial code for yourself:
