Is NI usb-4431 possible to use in Simulink?

Hi, first post here!
I have been having some issues with connecting my NI usb-4431 with simulink and specifically simulinks analog input-block.

First som info:

device: NI usb-4431

driver: NI-DAQmx v 9.6.0f0

operating system: Windows 8.1 64-bit

Matlab: matlab R2015b 64-bit


Ok, so I have been using the session-view of the data aquisition toolbox in matlab and everything have been working fine when just running scripts. I would like though to be able to use the NI usb-4431 in Simulink but I cant find the device in the analog input block menues.
So questions:

Is the problem that my device isn´t supported by simulink?

Can it be that I have to have the 32bit matlab so I can run the legacy-based interface?

Have anybody have similar problems and solved them somehow, then please tell me!


Best Regards

Hi Johan,


The problem isn't that your device isn't supported as it is listed under the supported hardware. I would first check through the documentation that is provided, I have found a few links here if these are helpful:


Supported hardware


NI Hardware:


Installing device support:


I would also suggest updating to the newest version of DAQmx to make sure that isn't the problem:


DAQmx 15.0.1


Best regards,
