USB-6009 DAQ

Hi;
Would you please advise which NI-DAQ software version is for USB-6009 using LabVIEW 7.1?
Regards

Hi;
I have downloaded NI DAQ MX 8.9 which is supports LabVIEW 7.1, but it can not detect the NI USB-6009 driver and still asking for the driver.
Can anyone help please?

USB 6009 DAQ to use in Simulink at External mode with DAQ toolbox

hi
Currently I am using usb 6009 daq board for data acquisition in using simulink. I have created a model with taking analog input from data acquisition toolbox. Then when i want to run in external mode and try to connet to target, the following error is coming up:
Could not execute target data map file 'untitled_rtwin_win32\untitled_targ_data_map' or it does not exist. Stop the target, delete the untitled executable, rebuild the code,and try again. Note that execution of external mode requires the build directory to be present...
How can I solve this problem? For your info, I am using 32-bit matlab, version: 2012a
For your info, a snapshot of the error is attached,
Any help would be appreciated Thanks

Separate sampling rate for two different channels for a USB-6009 daq

Hi,
I am using a USB-6009 and incorporating the 'daq assistant' to change the sample rate. I am trying to find a way to set the sampling rate to two unique values for two separate channels. I've tried setting up two daq assistants and adjusting the sample rate different for each channel, though this does not work. Is there any way to set the sample rate high for all channels then reduce the rate for a different channel - or an alternative? I would appreciate any input on this, thank you!
- Anthony
Solved!
Go to Solution.

All tasks on a DAQ board that use a sampling clock must use the same clock. Therefore, you cannot have two tasks on the same DAQ board sample at different rates.
Alternatives would be:
1. to combine all of the channels into a single task and just accept the extra data
2. get an extra DAQ board to use in parallel

Can I get four inputs voltage reading from four sources at a time from NI USB 6009 DAQ

I had a photoquadrant detector with four quadrants . each quadrant have a positive lead. If i connect each lead to the DAQ's a0, a1, a2, a3 terminals and common ground to one of the ground of DAQ. Is it able to read four voltages from four quadrants at a time . And how to take the data through labview. In the manuals it's not shown can you provide me an example program.when i configure daq i'am selecting acquire signals--->analog input--> selecting a0,a1,a2,a3---> then configuring each channel with voltage limits all. then ok. Afetr that on the DAQ VI how can I read these four values. Is it by giving add inputs and put number indicator to each data like that or any other way is there. If you help me it's a kind job

Use the DAQmx Read. Choose a polymorphic case of N channels. It is up to you whether you want multiple samples as a array, multiple samples as waveforms, or single samples. The multiple samples as an array will give you a 2D array, the rows being the channel. The other options will give you an array, an index for each channel.

Usb - 6009 Device Recongition Problems

Hi,
I just got a USB-6009 DAQ. I have labview 7.0, drivers software and the supplied software installed with no problems. In the measurment nad automation explorer (MAX) the device is recongnised and declared problem free. I tried to test the device in labview using help tutorials which suggests the DAQ assitant block. After selecting Analogue input and then voltage I am told that no device is detected i.e. Where I should be selecting my terminal(s) I am not giving any options.
If anyone has had the same problems or know how to fix them I would be thankful of your help.
Kyle

Hi Kyle,
The USB-6009 device works on DAQmx base. This is a restricted version of NI-DAQmx which is used on some of our products. Unfortunetly it is incompatible with DAQmx and the DAQ Assistant uses DAQmx. Therefore you can't use the UDB-6009 with the DAQ Assistant.
To use the device, load up the USB-600x Interactive Control which should be located in the following directory.
C:\Program Files\National Instruments\LabVIEW 7.0\examples\daqmxbase
Take a look at this and figure out how the code works. If you want to configure it to do your own specific functions then I would suggest that you use this program as a base and customise it for your purposes.

Measuring temperature Via Thermocouple and USB-6009?

Hi,
I am trying to perform temperature measurements using a k type thermocouple and the USB-6009 DAQ. I tried to use the Cont Acq Thermocouple Sample.vi from LabVIEW's example list, but unfortunately I don't know how to fit my DAQ and thermocouple in the vi code. I don't know how to create a thermocouple temperature measurement channel or how to get all the channels in the task, etc.
Any help is appreciated.
Thanks.

bilbeigg,
It should be noted that the USB-6009 is not well suited for thermocouple measurements. It has 14 bits of precision with a minimum input range of +/-1V, which means it can only detect a voltage change as small as about 122 microvolts. This is much too large a change to get a good temperature reading with most types of thermocouples. Here is a discussion thread on the same topic (Note that the USB-6008 and 6009 are very similar):

USB-6009 Sine Wave

Hi,
I am new to LabView and am having some trouble. I need to input two sine waves into a USB-6009. I have a voltmeter that should read the output. Two of the problems that I have had thus far: I can only use "On Demand" in DAQ Assistant and even when I throw the DAQ Assistant into a while loop I still do not get a readout on my voltmeter. Any suggestions? Thanks for the help.

That is confusing. You say you need to input 2 sine waves into a 6009 and that to me implies that you are doing a DAQmx Read. Then you say you have a voltmeter to read the output. That implies you are doing a DAQmx Write. If you are really doing a write from the 6009, then on demand is, of course your only choice. As the specs clearly indicate, the output of the 6009 is strictly software timed so you would need to pass a sine wave point by point and then you would have very little control over the frequency. And, again as the specs clearly state, the fastest output rate you could expect is 150Samples/sec.

Usb 6009 multiple analog inputs

I am currently attempting to sample two different analog inputs at different sampling rates using a USB 6009. I keep getting the 'resource reserved' error and am wondering if this is not possible using this DAQ. Questions:
1. Does creating two analog input channels on the device cause this error?
2. Is it possible to sample at different rates on channels created in the same task? (i am trying to 'slow down' the second analog input to display switch points to a customer)
3. Running multiple analog inputs using independent timing would be better achieved by switching to a higher end DAQ? If so which would you recommend?
I have attached my vi. Thank you in advance for your help.
I surf therefore I am....

The DAQ boards only have 1 timing clock for the analog inputs/outputs. So you can only have 1 sample rate on a given card. I would recommend just sampling at the highest of the desired rates in a single task.

USB-6009 Temperature Acquisition

Hi All
I seem to have some brain fade today. I need to use the USB-6009 to with a J type thermocouple. When I hook it up the temperature is not correct and widely varies. I am getting reading from 0 to 60 C at room temperature. I need to incorporate this into another circuit for testing. I assume that I am overlooking the simple and obvious. I have tried using a DAQ Assistant and a DAQmx. Any help will be appreciated.
Thanks
Gerald

Hello Gerald,
You don't have a brain fade! I recently got in a few usb-6009's and am seeing a similar response when trying to measure temperature with thermocouples.
I don't believe this is noise as much as resolution on the usb-6009. At this point I have added resistors to bring down noise but am seeing the same "waver" that you describe (although not quite as extreme). I am looking into building a signal amplifier or alternatively purchasing a TAC80 thermocouple-to-analog converter for use with the usb-6009.
Have you had any progress with your issue?

USB 6009 Python Control

Hello,
I am attempting to use python (with ctypes) to control my USB-6009. The goal is to write out an analog voltage and then read in the voltage through an analog input with ability to change the number of points averaged and the number of times this is repeated(sweeps) averaging the analog input array. The issue is that as we increase the number of times the voltage ramp is repeated (sweeps) we get a time out error (nidaq call failed with error -200284: 'Some or all of the samples requested have not yet been acquired). This has us confused because the sweeps are in a larger loop and the Daq function should be the same if there are 10 sweeps (works) or 1000 sweeps (crashes). Any insight would be greatly appreciated.

Usb 6009:connecting the sensor and motor

Hi there,
I am new to the labview also the usb-6009. I want to know if I can connect my sensor to the device. The output of the sensor is either analog voltage, pulse width or serial.If I want to use the AN pin, can I just connect the wire to the ADC from the usb or I need to add some circuit before connect it to the usb?also, if I want to control the brushless dc motor with the driver, can I just connect the wire from the motor driver direct to the device? How to connect it?
Thanks

You can connect analog voltages directly to the USB-6009 to be measured as long as they do not exceed the input limits (-10V to +10V).
Connecting the motor directly to the outputs is a bad idea.
Digital output is 0-5V, 8.5mA
Analog output is 0-5V, 5mA
So unless your motor draws less than 5mA (extremely unlikely) you'll blow up your DAQ!
You will need to buffer the outputs somehow unless you are just driving logic gates.
It's all on the datasheet... http://www.ni.com/pdf/products/us/20043762301101dlr.pdf

USB-6009 Analog Waveform Output

I'm trying to create an analog waveform from a USB-6009 device through one of the analog output channels. However, through the DAQ Assistant, I can only select the 1 Sample (On Demand) setting. When I test the device, I can only push a constant voltage out. If anyone has any advice on how to create an analog voltage waveform using this device, I would like to know.

>I am only a novice at LabVIEW and data acquisition in general.
I don't use Labview (I write in C++) so I can't help you with that. I try to answer questions about C/C++ and general hardware questions.
>What did you mean by software-timed waveform generation?
That's where the software driving the device sends a sample to the DAQ device, waits for the prescribed time interval, then sends the next sample. So the timing of the waveform is driven by the software, using the computer's clock, instead of by the DAQ hardware. Software-timed is less reliable and has (often) lots more jitter because of competition for CPU resources.
>Does this mean that I cannot generate a waveform that is more than 150 Hz?
It's worse than that. It means you can't generate a waveform faster than 150/N Hz, where N is the number of samples (data points) that define the waveform.

USB-6009 pulse train generation with digital output....

Hello!
I've bought a new USB NI-Card (USB-6009) and now I'm trying to adopt an old vi that uses traditional DAQ drivers. I wrote that vi for a PCI NI-Card (PCI-6024E), which has two counters to generate two pulse trains simultaneously. Now I've only one counter and that's why I'm searching for a good way to create pulse trains using a digital output! The pulse trains are both ranging between 100 Hz and 100 kHz.
I'm sure somebody has an idea how I can solve the probem in the best way
Kind regards,
Peter

You can't do it with this low cost board. Both digital and analog outputs are software timed only. The analog out is rated at only 150 samples/sec and the digital is about the same. You can't even use one of the counters because it is not a hardware timed counter output. It is an event counter only as an input.

USB 6009, DLL

Dear Friends,
I would like to control USB 6009 through a C# DLL. Do you have any samples or document to develop a DLL for USB 6009.
Could you please provide, If you have any samples
Thanks,
Best Regards,
Rathan

How to create a DLL in C# doesn't really fit into a LabVIEW forum, I think you will find different online resources how to create a DLL in C#, maybe at MSDN.
Within the DLL you simply need to make the Function Calls to the DAQmx C API, where you will find examples online, or also provided by the driver itself.
Under Start>Programms>National Instruments>NI DAQ> Textbased Code Support you will find the C Documentation of the DAQmx API.
