USB-6009 with "redy to run" datalogger SW

To get a quick and low cost solution to my data logging need, I bought a USB-6009 which ships with "ready to run" data logger software, NI Data logger. Well, I guess this SW is nice to see if you data USB-6009 works, but for anything else it seems quite useless. It seems that I am only able to log one channel at a time. Whats the use then of having 8 channels? Or am I just missing the functionality in the undocumented SW?

You can specify a series or group of channels in one of two ways:
- A colon specifies a channel range (e.g. Dev1/ai0:7 for channels 0 to 7)
- a comma seperates a group of channels in any order (e.g. Dev1/ai1,Dev1/ai4, Dev1/ai5 for channels 1, 4, and 5)
This is the standard channel string for NI-DAQmx and NI-DAQmx Base.

USB-6009 with Labview 2014 on Windows 8.1

Hi,
I have trouble connecting USB-6009 OEM with my new laptop with windows 8.1. My USB-6009 OEM device is not shown up in NI Max. So when I check Device Manager, there is a question mark on "NI USB-6009 OEM FW". I tried to install Labview 2011 but still the same. When I tried to choose the driver in Device Manager manually, I can only find NI-VISA driver as the closest one. It is still not working when I open DAQmx to check my card. It is still not detected in NI Max and anywhere within labview. When I used NI-VISA driver, and try to connect the device in NI Max, I get timeout error. I think I need to see NI-USB driver instead of NI-VISA driver. Any help would be appreciated.
Cheers,

Hi Thoo,
You may also want to try reinstalling the DAQmx 14.5 driver first. DAQmx 14.5 is supported on Windows 8.1. Some of the driver files may have been corrupted and reinstalling the driver may solve the issue. If not, using the DAQmx Base driver could be a good option as Dennis suggested.

Setup Problem in Measure 2.0 with USB-6009

I purchased a USB-6009 for my laptop (running XP Pro), and installed the NiDAQmx vers. 7.5 that came with the unit. I opened NI explorer, and tested the unit in there (using Test Panel). It worked nicely there, though the indicator light on the DAQ board was blinking. I then added my copy of Measure to the computer, but when starting MS Excel, I get the error message "Measure unable to detect a valid installation of NI-DAQ. Please install NIDAQ before using Measure for Windows Data Acquisition Add-In."
Is there a step I missed? or is there something wrong with my applications?

Hello dlclough,
Measure 2.0 is a Legacy application that works only with our Traditional NI-DAQ Legacy driver, not NI-DAQmx which supports the USB-6009. The blinking light on the USB-6009 simply indicates that the device is receiving power. However, if you go to this section in the Readme file for NI-DAQmx 7.5, you can look at your numerous options for programming NI-DAQmx. You can also use VI Logger Lite which is installed with the driver for simple data logging applications.

USB 6009 thermocouple noise

I'm using NI-DAQmx 7.5, Labview 7.0, and a USB-6009.
I'm trying to get a more accurate reading from my j-type thermocouple. It is now distorted with noise and jumps rapidly +/- 20 degrees around room temp without any heat being applied. When heat is applied, it climbs as it should but with the same variation. I haven't moved to the labview side of it yet, I'm still trying to get a usable reading in MAX. I have it wired as a differential input with a floating signal source. I've installed 10k ohm resistors for bias current return as instructed. Installing the resistors helped but still leaves me with the readings shown in the attached pic. I've also tried grounding my USB 6009 with no results. Please help. john

Hi John,
What you are running into is a problem with the actual voltage resolution of your USB-6009. This device has 14-bits of resolution over a minimum range of +/- 1V. That means that the voltage resolution is (1 - (-1))V / (2^14) = 2V / (16384) = 122uV. While this is an excellent resolution for such a low cost USB device, you will still notice problems when trying to make a thermocouple measurement. The reason for that is that Thermocouples make a very small output voltage (see image below).
Common thermocouple types have the following response:
K type: 41 microVolts per degree Celsius
J type: 56 microVolts per degree Celsius
T type: 52 microVolts per degree Celsius
There are a few options for ways to get around this limitation.
Good: You could read the signal in as a voltage and then manually convert that voltage into a temperature. This would be the least accurate method, but it should allow you to average out your signal and then use the Convert Thermocouple Reading.vi to show the voltage as a temperature.
Better: If you want to keep using the USB-6009 to measure thermocouple, what you really need to do is first amplify your signal before you connect it with your device. This should increase your resolution of the thermocouple allowing you to get more accurate temperature specs. This will require some more complex programming to properly scale your measurements, but it will give you more accurate readings for relatively little cost.
Best: Opt for getting a USB device that is designed for taking temperature measurements such as the USB-9211A. This device would give you a voltage resolution of 160mV/2^24 = 9.54 nV! That's over 12500x the resolution of the USB-6009 that you currently have.
Hopefully the above information helps you better understand what is going on and why. If you have any other questions feel free to post them here.

USB-6009 labview 7.1

Hi can anybody tell me if they have had any problems running USB-6009 with Labview version 7.0? I can't get it to recongnise my device and it's behaving as if there is nothing there. Do I need version 7.1 or is there a more sinister problem afoot?
Kyle

What version of DAQmx Base are you using? The latest version, 1.4, is supported on all versions of LabView 7.0 and higher. It can be obtained using the following link:

Hello Jamyamdy,
Honestly, I am not too sure about this, but were you able to acquire data before or is this your first trial?
From the usb-6009 product page, it says the following.
For Mac OS X and Linux users, download the NI-DAQmx Base driver software and program the USB-6009 with NI LabVIEW or C.

Usb 6009....mx base....and other musings

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.

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)?

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.

Relay for use with USB 6009

Hello
I would like to control a Red Hat solenoid valve with the USB 6009 (Very neat and economical multifunction DAQ!). The USB 6009 has some digital output lines specified as TTL. Can someone advise me as to a suitable relay for a 120V AC valve with a 6Watts power consumption?
Thanks John Brohan

John,
Here is the simple solution to your problem. You can tie two or more ports together which to get higher current capacity.Make sure you use the 4.7k pull up resistor after tieing them together.Then output all the tied ports together as if it is one port. In your case if you need 20ma you can tie-up 3 ports for 24ma capacity.
Warning!!!! You have to turn all the ports ON or OFF at one time otherwise it may burn the board.

USB 6009 lock-ups?

Hello,
I'm having a strange problem with my newly aquired USB 6009. I've written an app to read the temperature from a temperature controller using the 6009 and that all works fine. However, the problem comes when I port this code into another application. The code is intended to run in a parallel loop to the main execution loop, to continuously read the temperature whilst other data is captured and process (all done in the main loop). Both applications run quite happily when separate. When I bring them together the applications sometimes, but not all the time, refuse to quit and just lock up. I have no idea what is happening as it is not a case of one loop remaining running (I've tried separate stop buttons) and they will run together quite happily. The problem only comes when I hit the button that terminates the main loop (this also triggers the other loop to stop - I'm sure this bit works as I've used the same method in another vi).
The main loop should, in theory, just close. The loop with the USB reads (using DAQmx Base) will stop and then clear the task (DAQmx Base Clear I think). Sometimes the DAQmx Base Clear runs and the program stops fine, other times it runs and the program locks, other times it locks as soon as I hit the quit button.
Any thoughts as I'm completely stumped on this one? Like I say, apart from the one button triggering both loops to terminate there is no link between the two loops.
My only thought is it could be a USB issue as the PC also has a USB keyboard and mouse. I know from my home experience, when for instance plugging in my camera, it can cause the USB to lock if, say, my USB modem is running.

Usb-6009 high-speed continuous acquisition for slow control loop application

Hi,
After watching a few Youtube videos, I successfully built a control loop in LabVIEW using my USB-6009. Currently, this loop is limited by the speed my actuator can take and respond to commands, topping out at 200 Hz. This is completely sufficient for my application. My question is more regarding the wasted potential of the USB-6009 to acquire samples at a much higher rate than what would be obtained if I used a simple single sample-on-demand during every iteration of the loop.
It seems to me that having the USB-6009 continuously acquire samples and having my control loop periodically check in for the latest data when it is ready to execute would have the advantage of allowing me to average groups of samples together to lower the overall noise associated with the measurement process (I am reading voltages from an amplified photodiode).
1) Does anyone know how I would instruct the USB-6009 to continuously acquire at say 10 kHz, so that on each loop I will have 50 or so samples that can be averaged together for a more accurate measurement of my control variable? Unfortunately, I'm new to this and not too familiar with DAQmx Timing.vi.
2) I've heard that reading into a buffer can increase latency for moving data into the computer. Given the low speed of my control loop, I don't foresee this as being a problem. Is this a correct assumption? I can probably live with an extra millisecond of latency.
3) I goofed around briefly with DAQmx Timing and managed to see a buffer overflow error. Certain rare events will by necessity cause my control loop to take much longer to execute, so I cannot guarantee that occasionally during normal operation I will not overflow the buffer. Can I suppress this error so that the dialog box does not pop up and the program continues to run uninterrupted? If the buffer overflows and old data gets overwritten it isn't a big deal for me since the control loop is only concerned with the latest data anyway.
Thanks for any info!

Howdy Patrick!

USB 6009 DAQmx Deployment

Hi.
I have created a 4 channel differential data logging scope with a NI USB-6009. I would like to deploy this 'easily' to many of my colegues. I have app builder and the ability to build apps, but I would like to include the correct drivers for the 6009 in with the installer (although I have selected NI_DAQmx Core Runtime and NI_DAQmx MAX config support).
For the running of the app, I have created a Task that consists of 4 channels. I would like it for my end user not to have to configure this. Does anyone know how I might acheive this? My experience of deployment is limited.
Many thanks, Alec

Hi Alec,
It's also worth installing DAQmx MAX Configuration Support from the install builder if you still want to be able to modify the tasks from MAX as well.

USB-6009 digital input change detection

Hi,
I am trying to acquire digital signals from an ni usb-6009 device using daqmx on labview 8.0. I need to write the signals from a port of the device to an output file only when there is a change in the signals and I am not able to do this successfully. I created a digital task in MAX and was able to select acquisition mode as '1 sample (On Demand) ' only. Any other selection for acquisition mode would result in error 200077 with the following message -
Measurements: Requested value is not a supported value for this property.
Property: SampTimingType
You Have Requested: Sample Clock
You Can Select: On Demand
I selected '1 Sample (On Demand)' acquisition mode and was able to see the channel values on running it in MAX as I rotated a device connected to the usb-6009 device. As expected the hex values on MAX were showing up as FF,7F,3F,BF and this pattern was repeated everytime I provided the input by rotating the device.
Next, I created a simple vi to use the digital task I setup on MAX. I want to be able to record the signals only when there is a change in the digital pattern from the channels.That is when there is atransition from FF to 7F to 3F and so on, the vi should write to an output file and if no change happens, it should not write to file. To do this, I explored the Timing vi and tried using the 'Change detection' mode, but that produced the same error as above.
Can anyone please suggest a way to accomplish what I am trying to do ? Any guidance will be a hugely appreciated.
Thanks
~Sej

All of that effort with sample rates, timing, change detection, etc ciuld have been avoided if you had read the specs. As you finally found out, the device only supports sftware timed i/o and no change detection. You wll have to do your change detection in software this is done with a shift register/feedback loop.

USB 6009 - Calibration of Analog Input (Mac)

Hi,
I have recently acquired a NI USB 6009. I'm using it under labview 7.1 on Mac OS X 10.4 (Tiger).
I can run the software examples and the datalogger without problems. However, the device seems
not to be properly calibrated, and I can't figure out how to do it from the manual. When I connect
pin 1&2 (analog in 0) to pin 32 and 31 (GND and 5V ref voltage) the software claims that the
measured voltage it ~3.7V (a multimeter confirms that it is in fact 5.0V). Can anyone help
trouble shooting this ?
Thank you in advance,
Niels

A little update : After thinking some more I realized that it's because
the USB 6009 is in differential mode, and I hadn't connected one pin. Now
however, I have trouble figuring out where to change/set this. None of
the programs (e.q. Acquire One Voltage.vi) seems to define this, so where
is this defined ?
Thanks,
Niels
