NI 9215-USB (BNC) on CentOS 7

[jamwheeler]

Hello,

What version of ni-daqmx (base?) do I need to install in order to talk to the NI 9215-USB (BNC) on CentOS7? I finally got my GPIB working using a third-party library (https://github.com/vddvss/linux-gpib-packaging/issues/2), but I haven't been able to list the device using the most recent ni-daqmx installed using yum from the rpms provided here (http://www.ni.com/download/ni-linux-device-drivers-2018/7664/en/). It doesn't seem like they're supported, from what I see in the README.

It says that the USB 9215 should be supported, but then when I click on the Linux driver, it says that it isn’t supported. Clarification would be nice.

I believe this knowledge article could be of use:

For what I see, your best bet would be to go with DAQmx base 15.0. In its readme file it enlist CentOS 7 as compatible and your USB-9215 is also listed. You can download it here:

http://www.ni.com/download/ni-daqmx-base-15.0/5644/en/

And its readme file is here:

http://download.ni.com/support/softlib//multifunction_daq/nidaqmxbase/15.0/linux/README.txt

I hope that helps!

Mine is a 9215, not a 9215A... does that make a difference do you think?

[eorivia]

I believe it does, but in the txt readme file (link attached to my previous response) one of the entries for "Changes from previous versions" list the support for USB-9215 added since version 1.3.1

Gotcha. Thanks.

I think I had tried this using the ni-daqmx included in the most recent CentOS .rpm repository yesterday, and then tried installing ni-daqmx v18 fom the .iso image, but without luck.

I will try the version that you have recommended this afternoon (Pacific time)

Now I am getting this error:

$ lsdaq

Detecting National Instruments DAQ Devices
Found the following DAQ Devices:
/usr/local/bin/lsdaq: /etc/natinst/nidaqmxbase/bin/daqmxbase_listdevices: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

Steps to reproduce:

1. Install CentOS7

2. Install NIKAL using NI-VISA 16 (because: https://forums.ni.com/t5/Linux-Users/NI488-2-15-1-1-fails-to-install-on-Centos-7-3-1611/gpm-p/356876...)

3. Install NI-DAQmx Base 15.0 from http://www.ni.com/download/ni-daqmx-base-15.0/5644/en/

[jamwheeler]

Next, I ran:

sudo yum install glibc.i686 libstdc++.so.6

Now I get this error:

$ lsdaq

Perhaps you need to run updateNIDrivers

I did a yum update, then I uninstalled nivisa16, then I installed nivisa17, then I uninstalled nivisa17, then I installed nivisa18 through the rpm -i sudo rpm -i rpm_RHEL7CentOS7.rpm, sudo yum install ni-visa.

lsusb works, but lsdaq still does not.

[jamwheeler · Accepted solution]

I got it. I had to install NIKAL v 17.5 for Linux in addition to the previous updates. After a reboot, I was able to see my device via lsdaq.

Because this is nidaqmx-base, and not nidaqmx, I don't have access to all the shiny features of the nidaqmx python library. However, PyDAQmx seems to do the job.
