Unable to use NI 9211/9162 with VISA

[PSheph]

I am trying to get some NI Hardware (9211 running in a 9162 USB Chassis) up and running with our other instruments which have VISA Python control libraries. I have used the NI-VISA Driver Wizard to generate the INF files, and I have gone through the special reboot procedure to allow the unsigned INF file to be installed. I finally have the device showing up in Device Manager as shown here. (The IVI Device is my power supply that is also hooked up via USB). Before I went through this process, the device was recognized as a DAQmx device, but I need the VISA interface working. What other troubleshooting can I do to get it to actually show up in MAX or Python as a VISA instrument? ( I do have both Keysight and NI VISA installed, but disabling one or the other does not seem to make a difference.)

Thanks,

Paul

Have no clue about Python.

You shouldinstall NI-VISA and NI-DAQmx.

Hi nyc. I have both daqmx and NI VISA installed. The device doesn't show up in the VISA device managers, or in any other way of querying VISA devices. Python is just one of those.

Thanks,

You mention something about NI-VISA driver wizard.

I have no clue what that is and in all likelihood broke your set-up.

Undo that mess!

It's NI's preferred (only?) method to put a driver on your system for using many of their DAQ units with VISA... I'd love it if there were just a native VISA driver that I didn't have to shoe-horn into Windows!

Visa is meant for communication busses like serial, gpib or tcp/ip. You should use daqmx to communicate directly with these devices.

And the driver wizard is also meant for communication bus devices not for daqmx.

Hi Albert,

All of our other test and measurement equipment are using VISA interfaces. I understand this may not be optimal for some NI devices, but I was planning on only managing one type of interface library. If I take your meaning correctly, it sounds like NI VISA is supported to make non NI equipment usable by NI software, but NI VISA is cannot be used to make NI equipment usable via VISA. Is that true?

Thanks,

Paul

I think you don't quite understand how the USB-9162 is suppose to work!

You've obviously have not read the User Guide or you would not have written what you wrote!

That is exactly what I meant.

thanks NYC for stating it in another way.
