• Pilot LabVIEW for GST 2014

  I use Labview for control Oscilloscope TDS 2014. I downloaded the plug and play driver to http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=540. I want to test the connection between the driver and the instrument. To do this, just make that started VI? I also need to change the default values in the screw or change something?

  The posted VI will not work because you do not send a termination character. You send the chains '-' and 'n'. Right-click on the control of the chain, then select '-' Codes display and retype the command.

  The example does probably not because it not GPIB. You must run the initialize function. You must also use the driver style more recent project. These examples have the initialize function and you probably should now work.

• How to trigger the camera and light pulsed with PCIe-1427

  Hello

  We recently bought an acquisition card NI PCIe-1024 and the NI Vision Builder.

  I am new to imaging applications and need support to get started.

  Application:

  We have a camera viewing a scene which is illuminated by a pulsed light source (e.g., a strobe).

  We want to use the PCIe-1427 as the master for the outbreak of the camera and strobe light.

  The first trigger (Ch 0) transmitting signals TTL to camera to 30 Hz (30 fps).

  The second trigger (Ch 1) send bursts of pulses to the strobe light to e.g. 10 kHz. This trigger must only send impulses all other images, so that we can save alternating light and dark images in order to perform background subtraction.

  I tried to set up the channels of the trigger and create virtual channels in the measurement and Applications Explorer, but apparently this is not possible.

  Since it is an application critical time, I'd appreciate an example vi that sets up the channels two trigger and download managers in the camera to get started on this application. Thank you.

  Software of NEITHER: LabVIEW version 10

  Materials: Device for the Acquisition of Image (IMAQ) PCIe-1427 driver Version: NOR-IMAQ 4.4 OS: Windows 7

  Thank you, Justin.

  I'll copy this request to the machine Vision Group as you suggested. I looked at the link sent you me and made progress (limited). I can see on an oscilloscope trigger signals, and the camera acquires images. However, I only managed to do work for pulse trains continuous, not a shots or bursts of pulses.

  No need to answer that. Thanks for your help.

• Cannot control the color sensor in LabView for Mindstorms

  Hello!  New here.

  I'm currently boning on LabView via 'LabView for Lego Mindstorms' for a possible job in the near future, and I encountered a problem from the beginning.

  I am programming my brick Lego of LabView to simply activate the color sensor which is quite easy: I'm building a while loop and inside I have a block of color sensor attached to a block of text that displays the light intensity of the probe in the text on the brick.  I compile and run the detector turns on and I can read the intensity constantly updated on the brick.  This part works fine.  I would now like to control the light sensor (that doubles as a light source with color LEDs) on the front of the LV Panel.  The book I'm using (LabView for Lego Minstorms) says I should block sensor on the entry "generate light' do right click and choose"Create--> Control"in the menu that appears.  A Boolean command button should appear connected to the sensor block in the block Panel and a push button should appear in the front panel.  This is not what is happening.  Here, the two things are different.

  (1) I have no port "generate light" click on right-click.  This is probably using a version more day of Mindstorms that uses of the book.  It's a matter of book/Mindstorms, which probably cannot be resolved here but I hope that the next issue of problems will make it irrelevant.

  (2) I right click and create the control, but rather than create a Boolean command button as the book predicts, it creates an icon "BrickReference.lvclass".  He connects very well with the light sensor and a corresponding block is created in the front panel, but it is a paper weight that I can tell.  I can't do anything with it.  There are no buttons to push, no slider, button, button radio etc and I can't seem to change into something that somehow work.  I have delete and don't create a no kidding Boolean button from the library, but it does not connect to the photoelectric cell and so I can not compile.  So now, I'm a little stuck.

  I searched "Reference of the brick" online in the context of LabView class and have found little or nothing that talks about its definition or how I can use it to control the light via the front panel sensor.  Help with the software section is not much help, and yet I'm sure there must be a way to control a simple Lego light sensor of the façade for debugging purposes and others.

  If you know what I'm doing wrong or if you know a finish around this issue that will allow me to control a Mindstorms brick from the front in this way, please let me know.

  Thank you!

• PCI-1422 and RS 232 control of a camera Hamamatsu ORCA-HR (HR C4742-95-12)

  Hello

  I'll have some incompatible problems when I try to control a camera Orca-HR (Hamamatsu C4742-95-12 HR) via RS232.

  I have a feeling that the problem comes from how the RS232 port emmbedded (emulated?) in the PCI-1422 is used or recognized by the various software that I've tested.

  So first, this port emulated/integrated should appear in the series, Max & list parallel port? I don't think, but he's not here, that's for sure. I have 'only' the projection of card PCI-1422.

  Case where I can access some of the attributes (accessible from limited functionality) camera:

  -By MAX I can change some settings so the snapshots of controller and make.

  -I can access these functions by IMAQ ('IMAQ camera set attributes.vi', etc. see Appendix vi example).

  -J' have a full control of the camera via the Hamamatsu Hipic 8.0 software, but only if I use the internal drivers and a different com port than those incorporated in the card PCI-1422 (Hipic offers not only port com in any case perhaps because there is no by saying?)

  Case where I can't access the camera at all:

  -If I try to use VI to a Hamamatsu (the most recent in sample screws & DLL or older version), it does not work: calls to any function of the 'tmcamcon.dll' return errors, pointing to the fact that there is no camera detected: the first sub_Vi (tm_initialize.vi) will return no error but zero connected camera and other screws return errors saying there is no camera using this handle, or no camera can be activated at using this handle.

  -I have NO camera control via the Hamamatsu Hipic 8.0 software if I use the DCAM API drivers no matter what com port (incorporated in the card PCI-1422 or other).

  Does make any sense to you?

  I just thought that the Hamamatsu screws cannot access the camera via emulation RS-232 of the PCI-1422. Is there a configuration setting, that I could use to those who do work and do not have to restart from scratch with IMAQ and with only limited functionality?

  Thanks in advance for your answers.

  Hello

  In fact, you can have access to the serial port integrated on the PCI-1422 map only with IMAQ functions.

  This explains that you cannot see in the section "Series and parallel" in MAX.

  I have not really well know PCI-1422, but there's probably a way to access the serial port on the card PCI-1422 in MAX.

  Camera attributes, you are able to access with IMAQ, y then the camera assigns the has camera driver.

  If you are able to access more attributes with Hamamatsu driver, it is the manufacturer who decided to restricted access to other drivers.

  But if you are not able to use the screw manufacturer, you should probably call him to find out why it works badly. Perhaps a version control problem or a update of the firmware?

• drivers LabVIEW for agilent e4432b, cannot find the way to control multitone?

  drivers LabVIEW for agilent e4432b, cannot find the way to control multitone? How to deal

  Hello Brownheart,

  Drivers for the instruments aren't supposed to cover all applications use of instruments, only for the most common uses. No matter if multitone is a common use for this instrument, a brief review of the functions available in the driver does not have this feature.

  What you have to do is to create your own config VI using the information of the use of the programming unit. Is not ideal, but at least the driver NOR provided gives you a starting point for adding this feature.

• Parental controls for Mcafee randomly disable/Internet and network are not protected... click on fix that everything becomes right guard, but the problem continues

  Not sure if there is an error or a breach of security on my system, but my Mcafee Cox Security Suite client will say sometimes randomly the Parental control has been disabled, and the network firewall and Internet has been disabled and must be fixed. When you click on fix, the problems will go away, but sometimes the Protection status check will reappear do later me wonder if someone attempts to access or attempt to take control of my computer in some outside way. Using Windows Defender and Mcafee Viruscan I found nothing so far, however in one file past a Nakido.exe was found and attempted to remove, it is no longer, but I seem to always be able to find traces of the file on my computer, which makes me wonder if the Trojan horse still has limited access to my computer and try to manipulate items and just has not been detected yet.

  Try to contact McAfee Support for assistance. But before that try one of these:

  (1) Windows Update
  (2) try to install the latest Service Pack
  (3) ensure that your compatible version installed in Windows otherwise (ask McAfee upgrade option to the compatible version)

• I just plugged my camera and uploaded new photos for my Creative Memories Photo Manager. Now when I go to the Safely Remove Hardware my camera does not show... only my external hard drive.

  Any help is greatly appreciated!

  Creative Memories Photo Manager probably ejected your camera after you import the images. Check the default settings and change them if you prefer something different.

  If your camera is not displayed as ejection, it is safe to remove it. Damage to the file system wouldn't be possible, but not certain, if he had written active file or buffer not released when the device has been deleted.

• What software and what driver is needed for cononpowershot A10 digital camera?

  looking for software and driver

  You don't need to be.  Just slightly the cable supplied with the unit or one of the readers of SD cards.  With cable, you plug one end into the camera and the other into the USB port and then turn on the camera.  A wizard will open that allows you to copy the photos on the computer.  If you have a SD card reader, you can remove the card from the camera and put it in the drive and then go to the map as you would with a flash drive.

  Good luck.
