usb 6009....mx base....and other musings

[cochenob]

I've recently received a few usb-6009 devices, and, like most of the other people here on the boards, have had my share of problems getting the things up and going.

If I understand correctly....

I can create an empty task in LabView with a VI.  This VI however doesn't give me the option of choosing differential or single ended analog in measurements.  To do this, I need to use the config utility to create a task, and then import it into my program. 

What isn't clear is HOW I get the task I create in the config utility into my program.  Thoughts?

I will admit that I'm a bit disappointed that the devices, while convienient in size and price, have so many idiosyncrasies in the software.  Not having the full arsenal of VI's or compatability with MAX makes getting these up and going a bit painful.

How about DAQmxBaseLoadTask()?

Doesn't seem to exist! 

Are there VI's or drivers that may not have been installed?

To set a channel as differential or single-ended, connect the "input terminal configuration" terminal on the DAQmx Base Create Channel VI (not the Create Task).  This is the same behavior as NI-DAQmx.

If you decide to use the Configuration Utility, you can load a presaved task by typing its name into the Task Name Constant.  This is actually the same control used by NI-DAQmx, but the NI-DAQmx Base task names are not automatically populated (due to the aforementioned lack of reliance on MAX).

Hope this helps.

NI-DAQmx 7.5 supports the USB-6008 and USB-6009.

Hi

I've been trying to get a USB-6009 to work for a few days now. I was using DAQmx 7.4 and DAQmx Base v 1.4. Max Explorer would show the device  under USB Devices but I couldn't get any of the Tasks from the DAQmx Task Configuration Utility to show up in Labview. If I used the intermediate vi's to create a task and a physical channel name I did get to take measurements with the device.

Since I realy needed to use global channels and tasks set up in Max Explorer I was hoping that the new upgrade to DAQmx 7.5 would solve the problem. I removed DAQmx Base and DAQmx 7.4 and loaded 7.5. Unfortunately I'm still unable to use the 6009 device. Again the device shows up in the USB devices and I'm now able to give it an alias but when I try to set up a global channel it says I have 'No supported devices found'. If I look at 'NI-DAQmx for USB Devices Getting Started' which I think was included with the 7.5 update that suggests that it should be seen in the DAQmx devices, but in my case it doesn't.

I guess I've missed out some crutial stage but as yet I can't figure out what that might be. Has anyone been able to use the USB-6009 with DAQmx 7.5 (or v7.4 for that matter)?

I'm just too impatient, I've just seen the link to the KB which explains the solution to my problem.

I havn't tried it yet but I'm sure it will be what I need.
