Question of the digital input USB-6009

Hello

I use USB-6009. I have problem in Input.I digital did not connect anything on all channels. But all of the DI/O channels generate 5 volts. And I tested the DI/operating system in the Test Panel also. All digital inputs are high. How I use it? Please suggest me the solution.

You're the one who said it was generating 5V. And I said that a fine should be detected as a logic one. Connect a gnd input.

When it starts, all of the default value of I/O at the entrances.

  • PCI-MIO-16-1 shows the digital inputs 1-7 on, without same cable connected

    Max, my PCI-MIO-16-1 shows the digital inputs 1-7 as having entries of tension without same cable connected to the Board. No amount of spin with her (to the MAX) seems so he can act correctly in input or output mode. It's true, there are voltages on these pins. If I connect my cable (to a TBX-68 block), I see that it has on $line0 (on port0) 0v, 5v on line7 and 2, 5V on the rest. Trying to put these lines to something else in MAX seems to do nothing. (I also can't control the OD, either.)

    This card has tried to get a couple of have Weiwei at high speed. Now that I'm branching out, I found a strange behaviour. Of course, I tried to restart and turn off the computer and turn it back on. Automatic test MAX Returns instantly with a message "transmitted", that gives me hope, even if I don't trust the speed at which it seems to perform the check.

    I'm a complete noob at this stuff. Is there something obvious that I might be dominant? Is there a way I can test more deeply that the card works as it should?

    The open connections to the TTL inputs are usually detected as logic 1. You are not testing properly. Connect an entry to two gnd or + 5V. Don't let them ever floating.

  • Reduce the period of sampling of the digital inputs of NOR-USB-6009

    Hello

    I need to read a line of digital input in the NI USB-6009 using NOR Express 2013 Signal box. I selected 1 sample (upon request) as acquisition mode. I need to define a smaller sampling period as 1 MS, but it gives error too short sampling period: "the current sampling period is too short.  Please specify a longer sampling period. ».
    I do not understand the reason for it and a way to slove this.

    Any help would be greatly appreciated!

    Thank you!!

    The 6009 doesn't have a clock that you can set for a sampling period. According to the specifications, the digital I/o is software programmed - sample on request you use now. I'm not at all familiar with SignalExpress but I don't think that you can find near a reliable khz sampling frequency on Windows or any other os non-deterministic.

  • Typical values for the external resistance of pull-up on a line of output digital NI USB 6009?

    Hi all

    I use a digital line on a USB-6009 to control a SSR by the attached diagram (in the manual USB 6009).  I don't have access to a variable resistor or box of 10 years, so I'm hoping to get a good approximate estimate for the value of Re.  When I connect the CRDD at a 5V supply, it shoots 8.2mADC when closed.

    Any suggestions?  Is there any other information I can post for help with the guestimations?

    Thank you!

    I have found an old box of decade Heathkit and understand the degree of correct resistance 100 ohms.

  • Problem of analog sinusoidal input USB-6009

    Hello

    I am a newbie to Labview. I'm using Labview 2009 and USB-6009. I tried to use USB-6009 to display the input sinewave of function generator signal. First of all, the perfect sinusoidal looking at the frequency of 1 kHz, but when I changed the frequency of 10 kHz, the sinusoid turned into a triangle wave. When I test the input signal, I put the 48 kHz sampling and Terminal configuration is CSR. Is there a problem with USB-6009?

    You really need to spend some time to study sampling and Nyquist theorem-not LabVIEW. To faithfully reproduce the shape of the sine wave, you must go to a sampling rate 10 times higher than your input frequency. With the 6009, i.e. limit the entry less than 5 kHz.

  • simultaneous monitoring of the digital input lines when executing digital writing tasks

    I'm writing a multithreaded application in C on Windows 7, using the 9.6 DAQmx API and device USB-6509. This requires that we constantly monitor several lines on the 6509 for entry, digital using the change of the device detection feature. You must also write the digital output without having to stop monitoring the input rows. It is very important that the input rows be monitored continuously for the duration of the project.

    In the DAQmx manual reading, it seems that it is impossible to make a digital reading as well as a digital writing occurs, even if these tasks are performed in different threads. (The same I understand, that it is impossible to have several tasks of digital entry running simultaneously.)

    It seems that it would be possible to launch the task for reading (configured with the change detection), to pause playback, start the writing task, pause the task of writing, and then re - start the task of reading. But - and this is the important part - for the duration of the writing task is running, is it possible to configure it to the task of reading will always monitor the lines, even if it's just stores the data in the buffer for these periods? The key is that the data will be lost.

    Thank you

    Each channel is independent. If you can get the input data that you export a value. You need not make a break each task. The two tasks are parallel.

  • With the help of USB-6009 with LabView 8.0

    I try to use a USB-6009 with LabView 8.0 box.  I DAQmx 8.8 (that came with the unit) installed and verified that the 6009 works correctly through MAX I also read on this site that the 6009 is compatible with LabView 7 or more.  However, I am unable to get LabView to recognize the device.  Using LabView, to use a DAQ hardware I have to select "Input" in the palette 'Functions'  But there is no range "Input".  Actually I can't find the DAQ Assistant Express VI anywhere.

    Do I need to use a different version of the DAQmx?  If so, which and where can I find it?

    Thank you.

    LabVIEW 8.0 is not supported with DAQmx 8.8. I think that the last version with support for 8.0 is DAQmx 8.6.1. You can uninstall 8.8 and install 8.6.1. You should really consider upgrading your version of LabVIEW. NOR has decided to limit support for 7.1 8.0 just now. The latest version of DAQmx manages to only 8.2.x and higher.

    Hello

    Page 19 of the manual USB-6009:

    http://www.NI.com/PDF/manuals/371303l.PDF

    Shows the internal circuits of the DAC are referenced to ground so there is no way to internally isolate it / provide any reference.

    Maybe there is another way to make the desired effect? I don't know the details of your request to suggest everything.

  • Analog input USB-6009 pegged about 300mV

    I have an USB-6009 data acquisition module.  I'm reading a (LM35)temperature sensor voltage. The sensor has three sons: one for the power, ground and one for the output signal.  The output is in the range from-1 to 1 V.  I have set up the 6009 for entry of CSR in this power range.  I turn on the sensor with + 5 volts and ground and measure the output signal using a multimeter (a wire to the Earth, the other to the output of the sensor).  Measures with the multimeter check the sensor works (output is environ.2 V indicating the temperature about 20 degrees C).

    Then I set the output of the sensor to AI0 and fix the sensor on the 6009 GND ground.  As soon as I do, the output voltage of the sensor passes approximately 0,3 v. I check this voltage with multimeter.

    I tried several channels to HAVE two different data acquisition modules and several temperature sensors.  The behavior is always the same (pegged at 0.3 V voltage).

    Any ideas what might be happening here?  Do I need to be concerned with the adaptation of impedance for this type of installation?  Thanks in advance.

    I now have this job.  I have used CSR, connected the sensor Vout to AI0 +, connected to AI0 + to ground through a 1.5 k resistor.  V connected + sensor for external power supply (12V).  Connected to the ground on the sensor on the ground on data acquisition.  I have no idea why it works, but the other solutions posted are not.  As long as it works, I have no complaints.

  • Problems with the digital input/output

    Hello

    I have a little problem with my card PCI-6143. I would use two connectors digital one as a starter and one as an output. Now, I have the problem that I do not know how I address them. The input works as I want but not the output.

    As an example. I call my channel output on this name: Dev1/port0 / line0:0.
    With this call, the application works very well. If I change the output channel to Dev1/port0 / line4:0 I get an error that the values can be read and 0 and 1 are valid values.
    I hope that the call is right, I wrote that out of my head.

    My questions are. Is it correct to call a single digital channel with this name?
    I'm not sure because I do not understand what these means 'line' and if I allocate really single channel or more.
    The second question is, can someone give me an example of how I assign two digital channels (how to address them)?
    I know it's maybe an easy question, but I can't seem to get it corrected.

    Hope someone can help me.

    Best regards

    The syntax that you use is intended to select several channels: the numbers are the initial and final channel in a subsequent channel list. Thus, written Dev1\port0\line0:4 means 5 lines are included in the read/write (FWIW written 4:0 has the same effect). It is redundant but good writing line0:0, which means a single line, but you can write to Dev1\port0\line0 which is simpler.

  • take the digital output USB-6001 always high or low in c

    Hi all

    I am new to the NI DAQ interface. I have a USB-6001 and I am trying to use this device to control some flowchart in C. What I want to do is:

    * set digital output lines with high and low intensity and change their status as needed (in C).

    I tested the device NEITHER Max--> Test panels and found that the device is capable to do that. Then I try to do in C. I have checked hace examples and function I use is one called "DAQmxWriteDigitalU32". I have problem in the understanding of its input parameters. I tried something with my own knowledge, but it does not work as I expected. Here is a test I did:

    data uInt32 = 1;

    Int32 wrote;

    TaskHandle taskHandle = 0;

    DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
    DAQmxErrChk (DAQmxCreateDOChan (taskHandle, "Dev1/port0/line7", "", DAQmx_Val_ChanForAllLines));
    DAQmxErrChk (DAQmxStartTask (taskHandle));
    DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,));

    taskHandle = 0;
    DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
    DAQmxErrChk (DAQmxCreateDOChan (taskHandle, "Dev1/port0/$line0", "", DAQmx_Val_ChanForAllLines));
    DAQmxErrChk (DAQmxStartTask (taskHandle));
    DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,));

    I just want to set ' Dev1/port0/line7' and ' Dev1/port0/$line0"at a high level, but only ' Dev1/port0/$line0' answer me. The second parameter of the DAQmxWriteDigitalU32 function is numSampsPerChan. If I replace (currently 1) with a higher value, such as 100, I see that "Dev1/port0/line7" sends a number of 1 output, then back to 0. So I guess that the problem is just that I understand not all parameters for the DAQmxWriteDigitalU32 function. Is someone can you please tell me how I can set up a line of digital output 1 or 0?

    Thank you!

    Hello

    I finally find a way to do it! The feature works very well, and my problem was not set the data value to write correctly. It seems that if I want to write a 1 to the port0/line1, I put "data = 2 ^ 1" rather than "data = 1", because by default it is the second bit of the port.» Similarly, "data = 2 ^ 7 ' high level to port0/line7. I find that this setting is surprising when you want to control an individual line. It seems more reasonable when you control the whole port. In any case, is to solve the problem!

    Thanks anyway!

  • How to count the digital inputs of the sensor

    IImsmd MicrosoftInternetExplorer4 normal 0

    I use a PCI 6221 OR-DAQ device and I want to count the total number of times that a sensor is activated. The sensor is connected to a digital line.

    Tadhg salvation,

    If everything you want to count the number of times where the sensor is activate, the best way to ensure this is to use a line from the meter, in the case of the 6221 try pin 37, Cnt 0 Src/PFI8. And take a look at the example of counting code digital Events.vi that you can find from the Finder example under Hardware Input and Output > DAQmx > Counter measures > County Digital events.

    Alternatively, if you use a digital line, just read the line, and if the sample is true variable increment held in one register at offset, similar to the Count.vi DI attached

    I hope this helps.
