Problem regarding NI USB-9161

[Rahul_Vijay]

Hello sir,

I am connecting NI USB-9161 Carrier for data acquiring with NI 9211 (4-Ch Thermocouple Module) but i am not able to see my NI 9211 module.

how do i take the measurement i don't know.

somebody please help, for reference a screen short of MAX is attached.

have you installed DAQmx?

It looks like you might have another software package from NI installed on your system (like VISA, labview, etc), but you need to install DAQmx to use the 9211.

I have the same problem, and I found that USB 9162 which is upgraded version could only work with DAQmx drive.

The NI 9161 carrier is developed to function only using the NI-DAQmxBASE driver. So, install this driver (version 2.2 for example) and your 9161 carrier will work properly.

Latest news tells me that the 9161 will be discontinued bij NI from december 2011. You should use the 9162 carrier instead; this one will work with NI-DAQmx.

As an addition to my last reply; it is NOT the 9211 which causes your problem! It is strictly the (9161) carrier that is only supported by the NI-DAQmxBASE driver and NOT by NI-DAQmx!

Hello,

Did you manage to find a solution for this? I have the exact same problem and as advised by everyone here, I have exactly the DAQmx Base 2.2 version only and nothing else. I tried this in both Windows XP and Windows 2000. The tech support team in NI is also finding it tricky. Tell me what you did and how you came to a solution.

Hi M'Dsouza-

As you saw in previous posts, the USB-9161 (and therefore the USB-9211 and USB-9215) are only supported by NI-DAQmx Base.  More specifically, they are only supported by some older versions of NI-DAQmx Base.  Current versions of NI-DAQmx Base and NI-DAQmx only support the USB-9162 (and USB-9211A, USB-9215A, and other pairings).  This KB and this KB have helpful information about NI-DAQmx Base support options.

Your installation of NI-DAQmx Base 2.2 should allow support of your USB-9211, but it won't show up in MAX.  Instead, you should use the NI-DAQmx Base List Devices utility (see your Windows start menu under Programs>>National Instruments>>NI-DAQmx Base) to find the NI-DAQmx Base device name.  Then, you should use your LabVIEW VI or the NI-DAQmx Base "C" interface to address that device by name.  Note that you need to manually enter the device name from the List Devices utility to address the proper device.

Hopefully this helps get you up and running.  Post again with any issues you see and we will try to help.

Dear Tom,

Thank you for your response. But I am afraid it didn't help yet. I tried what you said. Take a look the screenshots I am attaching. They all tell me the same thing. But from what I understand, for the device to be detected in Labview (I am using Labview 8.2), the device should show up in the "Device manager" and in MAX under "DAQ system" (or something to that effect) and not under USB devices as shown here. This has halted all my work for this whole week now. I hope someone can help me sort this out as soon as possible.

Thanks and regards,

M D'Souza

HI M D'Souza-

Actually, the device should not show up under DAQ devices in Device Manager or MAX.  As I mentioned in my previous post, with NI-DAQmx Base on Windows you should not expect it to appear as a DAQ device in MAX and it will not automatically show up in the device controls in LabVIEW.

The NI-DAQmx Base channel configuration utility you showed is one way to confirm that the device is present and recognized by NI-DAQmx Base.  The other way is the NI-DAQmx Base List Devices utility that is accessible from your start menu.  It looks like your USB-9211 is "Dev1" in your system; I would recommend that you confirm this with NI-DAQmx Base List Devices. 

Once you have confirmed this you will need to manually enter that name into your LabVIEW or "C" application, in the form "Dev1/ai0" for a single channel or "Dev1/aiN:M" for a range of channel N to M.  You should be ready to acquire data after that point.

Hopefully this helps-

Hi Tom,

Thank you for putting your advice more clearly. I have to admit I didn't really understand it the first time. Anyway, as per your advice I did look at the NI-DAQmx Base List Devices utility where I found the device to be indicated as "Dev 1". I had a look at NI-DAQmx Configuration Utility, under C interface (I am guessing that is what you meant by "C" application. There too it showed the same. But on opening Labview, I found I couldn't manually enter "Dev 1/ai0". Infact my keyboard seemed to be disabled in the dialog box and on clicking on "Search for device", no devices showed up. I hope I you are able to understand what I am saying. I thank you for your support. I hope you will be able to guide me through through this.

Best regards,

M D'Souza
