SCXI and USB 6210? Getting started...

• sensor pressure and USB-6210

  I am installing a USB-6210 to read pressure sensors (specifically: http://www.omega.com/pptst/PX309-100mv.html), with labview2013.

  Its one task relatively simple and should not be this hard...

  I used a similar system to take similar measures in the past, but its been awhile.

  I don't know if it's just a wiring problem or incorrect installation of labview (program), but I can't measure the tensions that are remotely close to the sheet of calibration of the probe.

  Thoughts?

  It turns out that my diet was not come out correctly. Passed to a diet different and everything works as it should.

• The streaming of multiple channels directly to CSV USB-6210?

  I would like to stream up to 16 channels of data to a CSV file. My sample rate can vary from a file in a file, but I can reach 1 kHz. I understand the disadvantage of using text rather than PDM or binary files, but I have to be able to read these files later with programs such as Excel (Excel 2007 can make 1 million points).

  I have no trouble writing to TDMS files as seems very straighforward. I wonder though, it would be more efficient to use the TDMS files as the data are acquired and then after I stop, read the PDM and convert to CSV or just directly save to CSV? I only say this because I don't know if Labview can broadcast on a text or CSV file at 1 kHz.

  The scenario. The user will begin acquisition (using the USB-6210) to start playback 16 channels, applying multipliers for some data, and then send to a drive. Don't worry about the file size, the operator will be told that if it samples fast it must limit its total sample time. He has the ability to run slower to achieve longer sampling frequencies.
  Bottom line is I want good data for all 16 channels timestamped. No header information, nothing other than data raw beginning to end.

  I've seen several posts where the notice has been using TDMS files. Yet once again, I am not opposed to that, but I need to end up with text files.

  LabVIEW can handle this, if you do it right.

  1. If you are not already, use the design data of producer/consumer model.  It should be a template provided with LabVIEW.  This will allow you to take continuous data because your data treatment/backup of the routines take place in a separate thread.  If the hard data recording longer than reading the data, LabVIEW will keep only the size of the queue more and more with new data and I hope that you will not run out of memory system.

  2 write. you data in "chunks".  If you expect to write each data point to the disk as soon as it is available so that will probably be very tax on performance due to the excessive amount of 'read/write' header to your disk controller information and other things.  It is better to save 1000 samples at once, for example.  This way you are 'hit"your disc 10 times per second instead of 1000 times per second.

  3 ASCII files are very large, but I too tend to use them due to their convienance.  If you think about it, a 32-bit value can be "12332.0123" which in the ascii code is rather 80-bit (1 byte per character, 8 bits per byte, 10 characters is 80 bits or more than twice the amount if stored as a number 32-bit floating point).  It is therefore logical that if you have problems with performance (even after the application of 1 and 2) you write to a binary file.  Then, you can easily write a program that reads the binary file and writes a text file.

  4. If your computer has enough memory, you could put everything in memory and save it in a file at the end of the data collection.  You will need to add more controls and other things if you were writing this LabVIEW application for someone else.

• Driver files that run the parallel port and USB port

  In the system information utility where to look to find the parallel port and the port driver USB, name of file that manages these?

  Know the drivers specific, is only half the story.  Why you looking for these drivers?  You have problems with your parallel port or USB port?  This can be caused by problems with drivers or it could be a hardware problem (hard to diagnose a hardware problem without good parts to swap and test).  If you need to update the drivers, you must use device (not msinfo32) Manager - or maybe clicking on an executable file that loads the drivers automatically (depends on how it is sent by download).

  Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need drivers (I assume that you want to the parallel port and USB ports), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  Or run the Setup program of driver provided by the vendor of the computer or the manufacturer of the device.  Be VERY careful get Vista compatible drivers for these devices are difficult to identify (they usually come with the numbers of model or something like that if they can have serial numbers) and using the wrong drivers could make the problem (whatever that is) worse.

  If you update the drivers succerssfully and the problem persists, then it is probably a hardware problem.  In this case, contact the manufacturer of your computer for technical support (hopeully it is still under warranty) or bring it to a professional computer repairman (NOT Geek Squad or one of those big store centers because they don't really know what they're doing and charge a lot for this level of expertise) to have the components tested and possibly replaced.

  I hlpe that aid.

• Amnesty International and counter sync + USB signal stream (USB-6210 vs USB-6341)

  Hi all

  I'm at a stage of identification of a material suitable for the following tasks:

  • 5 analog inputs (AIs) of reading at the same time, tensions at a rate of kSps (at least) 10,
  • application captures 2 inputs using timers (detection of contours with timestamps), square wave entry with duty ratio of 50 percent and about 1.5 kHz frequency and variable pulse width / frequency (from 2 sensors hall, representative of the DC motor rotation speed and direction, quadrature signals), resolution of timestamps should be (at least) 50 ns,
  • AIs and counters should behave in a deterministic way, and must be synchronized in a way,
  • data to be transferred via the USB port of a host computer with Matlab Data Acquisition Toolbox (unfortunately not LabVIEW).

  I've identified the long USB-6210 USB-6341 and potential candidates of material to accomplish the above tasks, but after reviewing several documentation and the topics of the forum, I'm still a bit confused, if both are fully working and my approach described below is not working properly.

  Counters: I intend to use the internal time base available 20 MHz as being the source of meter to get into account the resolution of timestamp 50 ns. External impulses hall are used as sample clock (about 1.5 kHz, see above). As the pulse width varies, the sample clock is not constant.

  AIs: Using a 10 kHz internal clock signal derived from the time base of 20 MHz for timing and analog inputs (trigger) start-up and counters simultaneously material should translate into the required synchronization and deterministic behavior.

  It work? Other recommendations?

  Next is the USB data transfer: all HAVE 5 and 2 data entry of the meter must be correctly transferred to the host computer (the corresponding rates are shown above). USB-6210 is capable of 4 USB signal flow, device USB X range (6341) offers 8 of them. Unfortunately, I could not understand the exact meaning of the expression "signal flow" still. Do I need 1 flow of input signals (would be 7 for my application described) or 1 stream for all analog inputs and 1 for counter inputs (lead 2 streams for my request). Is there no further details on this approach (more than Streaming of signals of NOR) USB signal flow?

  Any challenge to the described application that I might have forgotten? 6210 USB seems to a very limited number of entry PFI, maybe even too low for my meter participate application?

  Looking forward to your comments and advice.

  Concerning

  jAwA

  1. I recommend the X-6341 series on the M-series 6210 sake of counters/timers.  It is more of them, and each of them is more capable.   It can also have a great FIFO embarked for meters that may be important in certain tasks, although I don't think that you currently deal with one of them.

  2. your general concepts on timing & sync are satisfactory.  You will be able to share and to route signals that help ensure synchronization and determinism between the timestamps for your various tasks.  Note that for meter entry tasks, you need set up the trigger 'Arm Start' rather than the regular start trigger.

  3 is not authoritarian, but I believe that the flow of signal # will correspond to the tasks #.  For you, it would be 1 task of HAVE and tasks CI 1 or 2.  (Not clear if you have 1 Encoder with 2-channel quad that would require 1 task of CI, or if you have 2 encoders with 4-way quad).

  4. pay attention to the hall effect signals that are not virgins.  Digital filtering is available and probably better on the X-series, the series M.

  5. strictly speaking, edge detection is a type of digital input task that produces samples but no timestamps.  Ideally, I would like to parallel wires on the two digital inputs for the entries of detection and counter change to position quadrature decoding.   Then I would sample the counters Encoder 1 or 2 using the internal pulse 'event of detection of change '.  I would create another counter timestamp change detects pulses as well.

• HOW can I remove my Bookmarks Toolbar Firefox's "Getting Started" link? It wastes space and seems invulnerable to the attempted abductions.

  From the outset, I am on a MacBook Air, running Yosemite & the most recent Firefox Help. If your only interest in my question is for bash Macs, then (yawn) I'm not interested. If your interest is to help sincerely, then you have my interest as well:

  I'm stuck with a "Getting Started" Firefox link as the first 'signet' (left) on my bookmarks bar, I really want to delete: I was in the Apple computers (from the Apple] [e) & online since the mid-80s, so I'm hardly a naif in the digital world or Firefox newbie , so having a "Getting Started" link to life is ridiculous, AND I really need the space to accommodate MY choice! Then...

  I tried all ways recommended to delete unwanted bookmarks - Firefox, BUT when I pull down the "Show all bookmarks" command of bookmarks in the Menu bar, there is NO such thing as the "Getting Started" link, so I can't delete it there. I've even linked by clicking and dragging it out of the toolbar, but it does not (nor made more by dragging to the trash. Then, someone has idea of this insurgent link?

  You can try this?

  1. Open the Bookmarks Manager. In what is the Apple menu icon or the menu bar, click bookmarks > show all bookmarks.
  2. In the search bar search Favorites, type getting started.
  3. Delete the bookmark that opens.

• Clock and hw external trigger with USB-6210 on Linux with NOR-DAQmx Base?

  I have two devices USB-6210 I need to synchronize so that they both collect data exactly at the same time. I was told by support OR I can send the clock off Dev1/PFI4 and have the two USB-6210 s read the clock in through their own PFI0. I also want to trigger data collected for each device by sending a trigger off Dev1/PFI6 and have two devices to receive the signal on PFI2.

  All my attempts to try this are filled with error messages and my research online seem to say that's not possible with USB devices on NOR-DAQmx Base 3.4.0f2 on Linux.

  I "ve tried using example AI programs and those who do not seem to work either for external clocks. Here is the code I tried:

  #include "NIDAQmxBase.h"#include 
  
  #define DAQmxErrChk(functionCall) { if( DAQmxFailed(error=(functionCall)) ) { goto Error; } }
  
  int main(void){    // Task parameters    int32       error = 0;    TaskHandle  taskHandle = 0;    char        errBuff[2048]={'\0'};    int32       i;
  
      // Channel parameters    char        chan[] = "Dev1/ai0";    float64     min = -10.0;    float64     max = 10.0;
  
      // Timing parameters    char        clockSource[] = "/Dev1/PFI7";    uInt64      samplesPerChan = 1000;    float64     sampleRate = 10000.0;
  
      // Data read parameters    #define     bufferSize (uInt32)1000    float64     data[bufferSize];    int32       pointsToRead = bufferSize;    int32       pointsRead;    float64     timeout = 10.0;
  
  printf("Calling CreateTask...\n");    DAQmxErrChk (DAQmxBaseCreateTask("",&taskHandle));printf("Calling CreateAIVoltageChan...\n");    DAQmxErrChk (DAQmxBaseCreateAIVoltageChan(taskHandle,chan,"",DAQmx_Val_Cfg_Default,min,max,DAQmx_Val_Volts,NULL));printf("Calling CfgSampleClkTiming...\n");    DAQmxErrChk (DAQmxBaseCfgSampClkTiming(taskHandle,clockSource,sampleRate,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,samplesPerChan));printf("Calling StartTask...\n");    DAQmxErrChk (DAQmxBaseStartTask(taskHandle));printf("Calling ReadAnalogF64\n");    DAQmxErrChk (DAQmxBaseReadAnalogF64(taskHandle,pointsToRead,timeout,DAQmx_Val_GroupByChannel,data,bufferSize,&pointsRead,NULL));
  
      printf ("Acquired %d samples\n", pointsRead);
  
      // Just print out the first 10 points    for (i = 0; i < 10; ++i)        printf ("data[%d] = %f\n", i, data[i]);
  
  Error:    if( DAQmxFailed(error) )        DAQmxBaseGetExtendedErrorInfo(errBuff,2048);    if(taskHandle != 0) {        DAQmxBaseStopTask (taskHandle);        DAQmxBaseClearTask (taskHandle);    }    if( DAQmxFailed(error) )       printf ("DAQmxBase Error %d: %s\n", error, errBuff);    return 0;}
  

  When I run the resulting program, I see this:

  $. / acquireNScans-ExtClk
  The CreateTask call...
  Call for CreateAIVoltageChan...
  Call for CfgSampleClkTiming...
  Error-89136 DAQmxBase: route specified cannot be satisfied, because the hardware does not support it.

  For example, a clock and a trigger can be imported via one of the PFI lines by using a USB-6210 on Linux with NOR-DAQmx Base? A clock and a trigger exportable via one of the PFI lines?

  If so, does anyone have the code example illustrating how to do this, or can you at least tell me the names of the lines ("PFI0/Dev1" or other) so I can try again?

  Clues or suggestions would be helpful.

  Thank you

  -Tom

  The clockSource in the example specifies an output rather than an input channel channel. Change source "/ Dev1 / PFI0" solved the problem.

• Registration and getting started with the INK HP INSTANT

  Registration and getting started with ink HP Instant

  Note: your printer must be connected to the Internet via a wireless connection.

  How does that you will always have ink HP? Your printer uses Internet to let us know when to send more ink. Here's how you can get all the ink you need, delivered to your door.

  1. Buy an eligible printer.
      
  2. Enroll in a plan based on the number of pages you print.
     Ink, cartridge recycling and transport are included.
     No annual fee, change or cancel your plan anytime.3
  3. We'll will ship special HP Instant cartridges.
     Our cartridges have more ink than the standard HP ink cartridges, so you'll replace them less often.
  4. Billing service and begin after inserting your first instant HP ink cartridge.
      
  5. Your printer will tell us when to send handwritten entry.
     Your service is not based on how many cartridges you use, so print as many pictures of high quality that you want.

  • You will always have ink before you need it.

  The elements of the start menu are a few shortcuts to the files on the C: drive you mention.  Done that caused all the elements of Start Menu to disappear?  This is sometimes caused by viruses that hide items on the computer, make sure that the computer is virus free, run a Malwarebytes scan on the machine.  If the machine is free virus that then I suggest that you do a system restore to a point just before the problem started.

  HOW CAN I GET A HP LASERJET 4V IN ORDER TO PROPERLY USE THE OPERATING SYSTEM TO XP PRO AND USB USING A PARALLEL CABLE?

  The printer works at all with this cable?

  The cable has recognized and installed by Windows XP when you logged on to the computer?

  If the cable has been recognized, what steps have you taken to install the printer then (be as accurate and complete as possible)?

  You get an error message?  If so, please provide, without paraphrasing.

  This printer has already been installed on this computer?  If so, with what type of connection?

  And especially, what is the brand and model of the USB to parallel cable?  Many of them do not work.  See, for example, the comments here , which suggests that 25% of the units will simply not work.  This seems to be one of these products you should buy at a local store, rather than on the Internet, then you can continue taking it back until you get a working unit.
