Hello,

I can't open a channel of the NI 9237 Device in Matlab using R2011a is it a device support problem or is there any solution? That's the device info i'm getting:

>> get(deviceInfo)
     IsSimulated: false
          Vendor: National Instruments
              ID: 'ENET-14E1636'
           Model: 'ENET-9237'
      Subsystems: empty
     Description: 'National Instruments ENET-9237'
RecognizedDevice: false

and when i want to open a analoginput:

   s.addAnalogInputChannel('ENET-14E1636', 'ai0', 'Voltage');
  ??? The requested subsystem 'AnalogInput' does not exist on this device.

Thanks for any help!

Hi Dirk,

Support for NI 9237 was added in R2011b. NI 9237 supports only bridge measurements, so if you use R2011b , you should be able to use this device as

s = daq.createSession('ni');
s.addAnalogInputChannel('Dev5', 0, 'Bridge');

Look at this demo for more information on bridge channels.

Hope that helps,

Manisha

Hello, In my application, I have a cDAQ configuration with AI modules 9234 (for accelerometers), 9237 (for pressure and load cell) and 9215 (for proximity and temperature). All modules are put in one chassis cDAQs-9178. What is the valid sampling rate for this?

Thanks for your help!
