cDAQ-9174 connecting woes to MATLAB

[young440]

Hello all,

I am trying to connect my cDAQ-9174 with an Analoge In (NI 9221) and an Analoge Out (NI 9263) module to MATLAB. daq.getVendors yields: 

ans =

Data acquisition vendor 'National Instruments':

ID: 'ni'
FullName: 'National Instruments'
AdaptorVersion: '2.18 (R2011a)'
DriverVersion: '9.7 NI-DAQmx'
IsOperational: true

Note: I have tried with the 9.0 driver but this left the DriverVersion: 'unknown'.

Next when I try to daq.getDevices it yields: 

ans =

No data acquisition devices available.

I am running MATLAB as admin and I out of ideas. 

BTW I am running a Win 7, 64 bit box with MATLAB 2011a.

Thanks for the help!

Hi Young,

In terms of the hardware, the cDAQ-9174 is initially supported by NI-DAQmx 9.0.2.  So, if you're using NI-DAQmx 9.0, then it won't be able to detect the device.

It seems like you're using The MathWorks Inc, Data Acquisition Toolbox (R).  I can't say for certain how their software behaves, so I'd recommend contacting them regarding this behavior after installing NI-DAQmx 9.0.2 or later.  I would recommend that you keep using NI-DAQmx 9.7 (since it's the latest version) unless you have a reason not to.

I hope this helps!
