• Reading NI USB 6008 of executable

  Hi all

  I tried to find a solution in existing topics, but unfortunately could not find a suitable solution.

  I use a USB-6008 read a voltage on ai0. When I run the VI with the USB device connected to my development pc it works very well (DAQ assistant was used to read the value on ai0). After making an executable on my development pc also works. However, when I move the executable file on the computer on which I want to use it does not read voltage. If I start NI Max, I noticed that the computer is able to read the value, so physically everything should be good. To me, it seems that some link/link is missing from the software. Anyone know what may be missing/defective in my executable?

  OR DAQmx is installed on the computer on which it is to run.

  Is the device and channel named in the same way on desktop deployment as was the development of your PC?  Display the MAX on each PC and compare.

• USB 6008 weird analog voltage reading

  Hello

  I use the USB-6008 to measure a voltage of a Lithium battery, 3.66V.

  the battery come with a blocking diode (in series with the battery) of 1N5820, who have a fall of voltage drop of 0, 1V.

  battery with diodes in series (this is the way in which the battery is shipped with)

  -measure with DDM yield 3.66V without you connect to usb6008

  -measure with DDM yield connected to usb6008 (putting OUT VOLTAGE USB6008) 3.59V

  -able with USB-6008 performance 3.59V connected to usb6008

  battery with diode removed

  -measure with DDM yield 3.66V without you connect to usb6008

  -measure with DDM yield connected to usb6008 (putting OUT VOLTAGE USB6008) 3.66V

  -able with USB-6008 performance 3.66V connected to usb6008

  Thus, it seems that the problem is in the led in the series.  This is why the battery voltage has fallen to 0.07V? the series diode will hurt the USB-6008?

  Maybe people who know the circuits inside the USB-6008 can give me an answer.

  Thanks in advance.

  Hi learnerd,.

  The fall that you see is falling forward in the diode.  As an entry class device, the USB-6008 case has a relatively low input impedance (144kOhm) and thus draws a little current of the device.  Looking at the datasheet of the 1N5820 (http://www.onsemi.com/pub_link/Collateral/1N5820-D.PDF), Figure 7 shows that at 25 ° C, a draw of 50mA will cause a fall front of 200mV.  While the figure does not extend the curve below 50mA, extrapolating the given curve would indicate that a drop of 70mV would cause only a few current microamperes.

  A DMM will have a much greater input impedance (GOhms instead of kohm) and won't draw enough current to influence the measure, that's why you wouldn't see the decline with only the DMM.

  The diode will not harm the USB-6008 somehow.

  Good luck with your application,

• MAX and Mac (to control on Labview, NI USB-6008)

  Hi, I would like to order my USB NI 6008 card in my Mac. I'm using Labview, but I'm a real beginner. I get my sensor on my USB card data and I can use them in Labview to control an electric trolley. This project is for my review: engenering school.

  So, on PC (Windows), it's ok, but on my mac, I do not find MAX. And if I understand, I need MAX to create the DAQ Assistant and a few other VI in Labview. However, I have yet install Base DASmx 3.4 for mac os.

  Could you help me please?

  I'm sorry for my English, it's so bad. I'm studying french and I'd rather post here because I found no answers in the french part of forums of NOR.

  See youi soon.

  Thank you

  The USB-6008 camera is supported with DAQmx Base, Yes. You do not get MAX, but you can always control your USB-6008.

  Install LabVIEW 2010 and DAQmx Base 3.4and this should give you the DAQmx Base vis in LabVIEW palettes.

• USB-6008 how to move an executable file to another computer.

  Hello Forums NOR!  Please bear with me as I'm new to products OR as well as this forum.  Hope I have write in good advice.  I'm an electronics technician with over 30 years of experience in a variety of hardware and software that is trying to move an executable file from an old computer to Windows XP on a new computer Win 8.

  First of all, I just moved the file .exe itself.   When it is run, it produces an error dialog box: "Unable to locate the LabVIEW run-time engine" "this executable requires a 2011 version (or compatible) LabVIEW Run - Time Engine."

  Then I ran the installation disc driver supplied with the USB-6008 module.  Now, the executable will start but it does not seem to connect with the USB-6008, because it does not have the digital I/o.

  I can run NI MAX and see the USB module as well as test the analog and the digital I/o so I know the hardware works.

  I've been surfing on the knowledge base and found references to .dll & .vi type support files, but have no idea of which ones to get and where they might be.

  This is possible without having to recompile the exe file?  I have no access to the source files.

  Thank you!

  
  

• Component USB 6008 in Multisim

  Hello

  I conceive my system in Multisim 12 and I wanted to include OR components of the database.

  I need a component for the NI USB-6008 case and the other for the NOR cDAQ-9174 with two NI9217.

  My question is: these elements already exist (in the database, on the Web site of OR or a third party) or what I have to design?

  Thank you

  csiquet,

  Here is an example of a database of these parts NOR (symbol only):

• USB-6008, USB-6501 and Embarcadero C++

  Hello NEITHER and NOR users,.

  I spent a considerable amount of money several years ago on a number of devices USB-6008 and USB-6501 for a class that I teach on interfacing the simulations with realworld sensors and actuators.  Write us code using Embarcadero C ++ Builder and we wrote the code to interface with the jury of EZIO AD / DA via RS - 232.  The EZIO is much too slow and limited.  Given advertising NOR, we bought these boards, but after several attempts to get some information OR on the way to talk to these devices directly via C++, we have yet no valid response.  No, I don't want to LabView or any additional expenses.  I just want to talk to them directly.

  OR: are you ready to help with this, or not?  If this is not the case, although wanting to refund these purchases.  Announce as being accessible from C++, but you are not willing to provide any help of substance to this day...

  Yes, I am self-taught, write code, and old-school enough to feel that I have a right to know how to talk to all the devices I buy.  I confess my ignorance, but I'm sick and tired of secret corporate and misleading advertising.

  Can someone please provide me with enough example of code to start.  That's what we wrote for the EZIO:

  http://www.Duke.edu/Web/ISIS/Gessler/Borland/RealWorld-Ezio.htm

  We would like to start writing similar code for these materials of NEITHER.  If possible, we can buy more.  If this is not the case, these cards are useless.

  Kind regards

  Nick,

  When you have installed the DAQmx drivers to communicate with the 6008 and 6501, I assume you also installed programming examples? It is here that they are on my XP machine: C:\Documents and Settings\All Users\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C.  I don't think that Embarcadero C++ Builder is one of the languages supported, so you'll need to twist your compiler, but it should give you a good start.

• Acquisition of data NOR usb 6008: a strange problem: mxwcgoutrunsilent.VI is not respected

  Expensive OR

  Today, I bought an acquisition of data NOR usb 6008

  and I'm using labview in 2011
  the problem is appear when after I end the process of configuration of the i/o data acquisition Wizard

  the following image shows the mxwcgoutrunsilent.VI is ignored and an error has occurred

  

  someone can help provide this VI for me

  What is the complete labview modules can also so I could do a real time data acquisition

  Best regards

  mangood,

  You received an error code? If so, what is it? What version of NOR-DAQmx driver you have installed? It seems your driver potentially incorrectly installed, and you may need to reinstall the driver.

  Here is the link to the latest version of the NOR-DAQmx driver: http://www.ni.com/download/ni-daqmx-9.8/4297/en/

• Chip exchanged on the issue of USB-6008

  I have a USB-6008 data acquisition that went wrong in a set-up.  The MCU was getting very hot while it is plugged (I had a ground problem that it fried).  I ordered a new microcontroller and succeeded him, now he does not become hot at all when it is plugged in but I need for the flash I think.  The argument of doing nothing, the indicator light is not flashing and the computer does not even recognize whether he has a connected device if he acknowledges.

  Has anyone here done a repair like this?

  Where can I get the software to Flash the chip and can be done on my site?

  Thank you all,

  Hi ChillyWilly,

  You should contact the Customer Service and seek to return the unit.  If it is within 30 days of the purchase, this should not be a problem and would be much easier to try to flash the device yourself.  You will need the serial number of the device when you call.  Hope this helps!

• USB 6008 DAQ scaling

  Hello

  I use a USB-6008 to read signals from analog voltage to a device I built. The task is configured with a single reading finished with a range of + -10 volts. There is no scaling in the task or in the block diagram, but when I acquire data in a PDM file and view it, I get a load of PieceWisePolynomial scaling properties. I have attached the TDMS spectator to this post.

  Does anyone know where it comes from because I can't explain it.

  Thank you

  The data goes back as an unsigned integer between 0 and 32 k of the ADC on the 6008.

  The scale is to convert this unsignedInt to floating point value between-10 and 10.

• DAQ USB-6008 will be able to power and record voltage for UMS T5 blood pressure at the same time?

  I would use my NI USB-6008 to power my blood pressure monitor UMS T5 (http://www.ums-muc.de/en/products/tensiometer/t5.html) but also to take readings of it, but I don't know if it's possible to do it properly. The power supply for the instrument can be as low as 5V, I can easily get the dedicated + 5V channel. I'm able to feed the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, when you read the documentation of support for the instrument, I find the following:

  "Potential pitfalls of data acquisition: the pressure transducer is configured in a full Wheatstone bridge, the input voltage and mV signal output can be connected to the same reference (mass)." Therefore, the mV output signal can be measured using a differential voltage measurement. Therefore, do not make an asymmetric measure of pressure transducer mV output. "(http://www.decagon.com/assets/Uploads/MeasuringUMSTensiometerswithnon-UMSControlandDataAcquisitionSystems.pdf)

  My understanding is that the 6008 can take a differential measure if I attach the signal '+' and the signal "-" to the analog inputs of positive and negative terminals. However, it seems that all the ports of ground on the 6008 are grounded to the same reference, which would make my measure of invalid tension according to the above paragraph. So my real question is: if I try to record the voltage with one of the analog inputs on the 6008 in this way, is the valid measurement? Or I need to find a separate power supply, with a different reference field to ensure that the measure is accurate?

  The technical details of this device is very poor. The manual is not much better. Companies that want to sell scientific equipment should publish decent cards or get out of business.

  In section 3.4.3 General requirements the device is described as a "bridge not amplified circuit.  This information along with the impedance of the bridge should be in the specifications, because it is essential to apply the device under any circumstances other than the nominal behavior in 10.6 V.

  The answer to your question is:

  You can use it with the box USB-6008.  The 5 V supply will result in output voltages a little less than half (5/10.6) the voltage specified in nominal conditions. You can use the differential input mode on the box USB-6008.  The absolute input voltages will be approximately 2.5 V with the 5 V power supply. This voltage is in the range of the aircraft. The differences are likely to be less than 100 mV. The resolution of the USB-6008 on the + /-1 V is located about 0.5 mV so your resolution of pressure will be about 1% of full scale. The voltage input impedance and termination of the USB-6008 will present a few errors.  These can be in the order of 5 to 10%. I can't predict much better without the missing bridge impedance specification.  These errors should be relatively constant and systematic. A calibration of the whole system - sensor and together hardware DAQ should allow you to compensate for a large part of this error.

• Input/output USB 6008 test failure

  OK I am posting this for the third time, but whenever I go back to the home page of the forum, I'm not able to find my post. If by chance I created duplicates than apologies.

  IAM in train to test the USB-6008 case I just got and decided to hang the analog of the analog inputs and see using labview VI.the wiring was done as:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/USB%206008%20wiring_zpss2b7hql9.jpg

  the problem is that the labview VI did nothing, so I go to NI Max and try to see in test panels. But I get 1.4V constantly my same analog input value when I'm changing my analog value:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AIO%20screenshot_zps9beiimbj.PNG

  the analog output works very well since I plugged it to my multimeter and I can see the tension that I see on this Panel of test:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AO0%20screenshot_zpsqpei37bw.PNG

  I created an entry/exit of the tasks; screenshots of them are:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/task_ai_zpsix5se9yg.PNG

  I am quite frustrated with all this since I'm unable to access my actaul draft. I know that 1.4 V value is from the device itself; as in the manual it says 'internal resistance divider can cause the Terminal to float at about 1.4 V when the analog input terminal is configured as a CSR', but the funny thing is that I use it in differential mode so I don't know what to do and any help is appreciated.

  BTW, I did a google search and there are other tutorials onlune who seem to do exactly what I do and they seem to work very well; so I don't know what else to do.

  Please don't host images on some odd third-party site. Attach them to your message.

  I don't understand what you've done. The 6009 can produce only a signal of CSR in order to set up the differential input makes no sense. If you want to measure something different, try a simple battery.

• Beyond the limits of voltage on USB 6008?

  I use a USB-6008 to measure analog differential in the range of 3 to 5.3 V. I chose this range, because outside this range, I'm not interested in what the tension is, knowing that his "on the rail", but to aid resolution of the ADC in this range.

  So for a signal of ~0.05 supply V, I expected to read 3V, telling me that the voltage is lower than 3V, but again it returns 0.05v?

  As it was unexpected for me, could someone please explain what can / should I expect of my USB6008 of the responsed to the signals that are the limits? Is there an effect of "rollover"? Should you return the value to the limit? Depends on how far the limit is?

  Thanks for your help!

  Entry level do not think that way. You specify the range is that you wait for the signal and the DAQmx driver will set the most appropriate range that the device supports. The actual ranges are indicated in the guide. In your case, because you specify a max of 5.3, the device would be defined the +/-10 volts range.

• Pt100 (USB-6008) configuration problems

  Hello

  I'm using the hardware DAQ USB-6008 (I know that's not accurate and all) and I use the Pt100 (QAP2010, click for plug technique).

  I connected it like this.

  Now in LabVIEW, these are the only options (DAQmx new task-> acquire->-> RTD temperature signals).

  If I choose for custom settings, I get these options (I don't know what variables that is).

  I use a small greenhouse where I need to measure the temperature and humidity and control environment (by using a fan to cool the cartridges to greenhouse and heat to heat).

  My goal is to read the temperature using a graph on the front panel.

  Can someone help me how configure/choose the right options? If you need more information I'll provide them as soon as possible!

  A quick search for RTD class B shows the precision and the coefficient. As Fan Ravens stressed resistance according to the temperature is plotted in the data sheet.  To control the temperature in greenhouse, a simple calculation of the slope of this graph is not good enough.

  Note that the USB-6008 case limited an active player on the outputs analog and it controls only the voltage. So you will need at least one external resistor and possibly and external power to excite the RTD.  These options that you have linked is not applicable to the USB-6008, which is a very simple device. You should perhaps simply to measure the voltage and calculate first resistance, then the temperature.

• USB 6008 digital output signal

  I am VERY new to LabView and have been racking my brain trying to get digital output of my USB-6008.  All I want is to be able to get a signal of + 5 V of my digital output when I click on a button.  This signal opens a valve on a system I see so when it is pressed, it must stay open until I press the new button.  It seems simple enough to me, but I'm not too familiar with LabView.  Help, please!

  Stripling07

  You must first take the LabVIEW tutorials and then look at the links to get started with DAQmx .

  The simplest program would be with the DAQ Assistant. Drop it on your schema, and then select digital output > digital line. Select the line when the wizard has completed, click OK. Wire a Boolean value in a table to build and the output of which is connected to the data entry. That's all. You can test the output of MAX (Measurement & Automation Explorer) with the test Panel. Do NOT test with your connected tap. Your valve may require more current that can provide the 6008.
