finding NI cDAQ-9172 chassis

[lakersrl]

Hello,

I cannot find the NI cDAQ-9172 chassis in measurement and automation..Right now just specified as unidentified. Could anyone help me with this?

Hi,

What version of DAQmx do you have installed on your computer?  You can find the most recent version of this driver here.  Once we confirm you have the appropriate driver installed we can go from there.

I believe I have the recommended NIDAQmx driver, how can i determine this? also if this is the driver i selected, where woul i go from here in selecting the chassis?

thanks

Hello,

In MAX, you can expand the software tree and see your version of DAQmx installed.  Also, do you have a particular module installed in your cDAQ chassis?  Make sure that module is supported under DAQmx as well.  The user manual gives the full details to installing and setting up your chassis, but if the driver is installed and modules are in the chassis, as soon as you hook up the chassis it should be automatically identified under Devices and Interfaces.

Try restarting your computer if you haven't already just to check, and if MAX continues to misidentify your chassis you can try doing a MAX Database Corruption to see if that resolves the issue.

Hello,

Im using modules 9205, 9263 and a digital one, forgotthe number. But as for my driver says I have NI DAQmx version NIDAQ923f1..

Hi,

Did you try the MAX database corruption process?

[lakersrl]

yes ive tried that..other suggestions?

Ive been converting a traditional DAQ program to a program using DAQmx...the traditional DAQ program works fine, but the DAQmx converted program has the issues that I previously described.

how do i add NIcDAQ-9172  under DAQ mx devices? when I look for the instrument its under the devices and interfaces heading but not under the NIDAQmx subheading like in the measurement and automation picture from this link: http://digital.ni.com/public.nsf/allkb/C7167355FBB8CE84862574F3004A4BDA

Hi lakersrl,

For reassociating a device with DAQmx from Traditional DAQ, read this article here.  I would try this first before reading forward.

The cDAQ chassis uses USB to communicate to your PC, so as soon as you plug in the USB cable and have your PC powered on, it will automatically identify the chassis and detect the modules, and display them in MAX.  USB is hot swappable, so whether you plug it in with the PC powered down or on, you should see the hardware come up automatically.  When you plug in the device, the Add New Hardware Wizard should show up and start associating drivers with their respective devices. 

The picture you see is from previous versions of DAQmx.  Before v9.0, we had a separate folder listing that housed DAQmx Devices under Devices and Interfaces.  Post-9.0, we took that folder away, and now all devices show up under Devices and Interfaces.

When you plug in your hardware, can you see anything show up in your Device Manager on your computer?  Any unknown devices or National Instruments devices?  If you do see some listing, it would be a system software issue and I would look at trying to repair DAQmx or reinstalling to get the hardware identified correctly in the OS.  If you cannot see any listings of the hardware in Device Manager, there is some issue with the hardware, and I would try different USB ports, try getting it to work on a different PC, check the USB cable and connections, make sure the cDAQ chassis is powered on and that connection is good. 

If you still cannot get this chassis to identify, has it ever been identified and working on any other system or time?  It could possibly be damaged, and may need repair for it to work properly.  Testing on a different PC with DAQmx installed would be a helpful troubleshooting step to see if the issue is system specific or hardware specific.
