Is a PCI-6120 board in a computer with linux useful for analog output?

[gallas]

We own a PCI-6120, and we want to use it in a computer with linux OS, to do both analog input and analog output.  I have downloaded the NI-DAQmx Base 3.2 driver for linux, and in the README.txt only analog input is mentioned for this board. It is possible to use this PCI-6120 board in a linux computer, with both analog input and output?

Hi,

I'm sorry to tell you that you won't be able to do analog output with this card using DAQmx Base 3.2 driver, not all functionnality are supported on linux for this card.

Hey Gallas -

Have you evaluated using NI-DAQmx 8.02 for Linux? Per its readme, it does support the PCI-6120, and I believe, the AO capability.

Thank you for you answers.

I have read the README.txt of NI-DAQ 8.02 for Linux. The NI PCI-6120 board is supported, but in fact, only the AI (analog input) is mentioned in the README.txt, so it seems that the analog output is not supported by Linux. Here I copy the relevant line of the README.txt:

 " NI PCI-6120 800 Ks/s, 16-bit, 4 AI simultaneous-sampling device"

Hey Gallas,

That line in the README simply refers to the PCI-6120 by its most popular subsystem, the analog input (given that it is a simultaneous sampling device, the AI is the most commonly used subsystem). But NI-DAQmx for Linux does not have the same limitations that NI-DAQmx base has. In other words, it does support analog output capability on the PCI-6120.

Thank you very much, SamboNi!  Then, I will try to used the card with a linux system.
