• External triggering of GigE camera

  Hi, I'm planning on using the camera triggers the entry to start capturing images but I'm not sure what I need to do in my c# application when a trigger has launched.

  -If the trigger is coming from the PLC, should I also send a trigger signal to the PC and keep the active trigger signal until the PC is the acquisition of the image?

  -Do I still need use the snap or enter functions in imaqdx to get the picture?

  -If the camera is connected directly to the external NETWORK card triggering she still great benefits? The camera in less than 5 meters from the PC.

  Thank you

  Cliff

  Hi riscoh,

  When you work with a GigE camera you are not anything on the computer triggering its self, only the camera.  When it is configured to trigger it will sit and wait for a trigger.  When he received the signal it will take an acquisition and send the information to the computer.  When you set up your support on the computer it is searched for images and brings them into the computer as they become available.  The example I'm pointing you will show you how to set up the camera by a trigger program.  It looks like it may be available only in Visual C.  As far as the documents relate to article after the release with a GigE camera Developer area described briefly.  Acquisition of cameras GigE Vision with Vision Acquisition Software-part II

• [beginner on Labview 8.5] Generation of a digital camera modulated square pulse triggered by an almost periodic pulse analog modulated square

  Hello

  I use a mx-acquisition of data (NI USB-6211) and I would like to use it to generate a pulse of digital modulation

  that is triggered by an analog input signal. The input signal is a pulse of squares analog modulated

  What is almost periodic. It's because of my set up, and I can't do anything with it. I would use the

  before the edge of this signal to trigger the production of a digital pulse signal modulated (0-5 V). My

  problem is summarized in the figure given in the annex. I would also like to have the possibility of

  Configure the 'backwardness' and the term of "TAU_LED", while the VI works.

  I have looked at several examples of instrument OR meter generation, generation of PCI I / AO, but doesn't

  not managed to solve my problem.  Does anyone have an idea of how start with my problem? Are there

  No matter what example VI that I could start to change?

  Thanks in advance,

  Hi Gregory,

  Sorry I forgot to mention: the Initial delay applies only to the first impulse of a redeclenchables generation.  Every subsequent impulse will use low time as the Initial delay.  I agree the behavior is not very intuitive (our latest guidance of series X actually supported an Initial period to allow on property Retrigger), but it is described in this knowledge baseand should also be mentioned in the DAQmx help.

  As you generate just a single pulse, I would recommend simply connecting the Initial delay and at the entrances of low time to the same value for each pulse will be delayed further.

  Exit tasks ongoing counter currently supports DAQmx writing.  However, the finished generations or simple impulse are not.  However, you should always be able to get the behavior you need with a property node DAQmx.  The current solution on the series E/M is:

  

  Again, this is not the most intuitive, but I checked that it works on my 6210.  After writing a new value in the software the pulse will be updated on the 2nd trigger.  Attached is the code stored in LV8.2.

  Best regards

• How to make a simultaneous wink of GigE cameras?

  I have 2 cameras of 780-54gm Basler Scout (monochrome GigE) I switch to 10 Hz. This pace is modest and the data rate that results is not particularly high. I would like to get images from two cameras of the same trigger pulse. I have an Intel Pro/1000 NIC and I use the driver NEITHER appears so as National Instruments GigE Vision adapter. When I use the Basler pylon Viewer (the software that comes with the camera), I see perfect images from two cameras at the same time at 10 Hz. This tells me that the network, map NETWORK and the drivers can handle the flow of data without problem. I have activated jumbo frames. When I try to acquire images in LabVIEW 8.6 with screws IMAQdx, however, that I meet problems. I can acquire every single camera, but I can't them both at the same time strictly. The images are taken through with horizontal black lines that appear and move erratically. I have attached a vi that shows the problem. I have set up and start the two acquisitions, then enter a while loop that reads images. If I do the sequential acquisition by starting and stop them inside the loop and ensuring that we stop before the other then I get quality images but they are not the same impulses to trigger, and start and stop of the acuisitions overload slows down things so that I can not get pictures of each trigger. My guess is that it is a problem with how LabVIEW is the memory management, resulting in corruption with simultaneous acquisition. Are there settings I can change to fix this problem? I've experimented with everything I knew (buffer numbers, etc.), but without success. Rich P.S. I posted this in the forum LabView a couple of days but got no response. Sorry if you see this twice.

  Richard,

  Looks like you just packet loss. You might associate a property node to request lost packages to confirm. The reason for that happening is that even if the way to two cameras data rate is less than the limit of the NETWORK card, each camera probably goes to the complete 1000Mbit bandwidth when it transfers each picture. When transfers of images overlap, sending you to 2000Mbit/s down a 1000Mbit pipe and lose packets.

  To resolve this issue, an easy way is to adjust the attributes of Acquisition-> Ethernet advanced-> attribute peak bandwidth used for both cameras 500Mbit. This should ensure that each camera never use more than half of the bandwidth. There are also other options such as sprawl of transfer times, but those who require more tuning you change other settings.

  I don't know why the Basler software shows this, although their lack of bandwidth might just be lower at the expense of additional latency to get the images.

  Hope this helps,
  Eric

• How can I disable camera shutter sound each time something supported?

  I get a type of sound camera shutter when pages like Google or hotmail, or any page 'active', upload pictures on Web sites for example. Sometimes when things are moving quickly, it becomes a cascade of distortion of the sound, like a loud sizzle or worse. You can turn down the sound with the help of his usual device, but then of course you can not listen to any music or something else besides. It is extremely annoying, and now that I have synced my phone with my office they both the same problem. I checked all the settings and can't find a way to disable. I don't know exactly what is triggering, but it seems that when something is in charge.
  I use firefox 18.0.2 on a Mac running Snow Leopard 10.6.8. Is there anything else I can tell you?

• Volume up button does not work like the shutter of the camera

  I have an iPhone 5 with iOS 9.2.1 (13D 15). The volume up button does not work on it like a camera shutter. I think that it used for, and iPhone to my wife 6 with the same iOS version works fine. It is a problem, because I am using this phone with a stick of selfie, which triggers photos by simulating the volume press up button, so it doesn't work at all for me. The physical button works - I can control the volume with her settings. And when I try to use the stick selfie, I get the volume until the display on the phone, so I can see that the signal of the selfie stick is received correctly by the phone. And the stick of selfie works with my other phone that is not a problem with the volume up button.

  Work began after restarting the phone. So it's a bug to Apple report, the solution is to reboot the phone.

• Triggered Cameralink Acquisition only capture half of the executives

  Hi all

  I am aware of this page- http://digital.ni.com/public.nsf/allkb/6FFA526966E2D29386257AA80054730A

  He describes my problem, but I can't find a good solution.

  I have four cameras that should be triggered at the same time (they cannot be free running!)... If I only to trigger the cameras, and allow acquisition cards to run without a trigger, I find myself occasionally lack of executives at increasingly higher rates.  To 100 fps I have lost about 40 percent of the data, but about 50 fps I capture all the data correctly.

  When I trigger both the image grabber cards (1430 years) with cameras, I seem to always miss all the other images.

  I tried to trigger the cameras on a rising edge and the cards on the falling edge, but no matter what I myself only to collect half of the frameworks I expect to collect over a period of time.

  Here is a snippet of code that I use for the acquisition is something urgent?

  

  Thanks for your suggestions!

  -MK

  Triggering the camera still works best, in my opinion.

  You're doing an acquisition in the buffer?  The code you posted looks that you use just Grab, that does not use a buffer.  With an acquisition in the memory buffer and outbreak of the camera, you should not have problems.

• cannot trigger time DAQ and camera

  Hello

  I want to synchronize a camera and a pressure transducer. The pressure transducer is connected to an NI USB-6251 housing.

  I use a TTL signal to trigger (trigger signal is from a Labjack). If I only connect the camera, I can trigger without problem. If I only connect the DAQ card, I can trigger without problem. If I use a T-connector for both trigger the camera and the DAQ, only the DAQ card card is triggered.

  An idea of the source of the problem and how can I solve this problem? Thank you!

  Charlotte

  OK, so I checked my TTL signal, and it was disrupted once cut in two. I pulled out another TTL signal such as the camera and the DAQ card each has its own TTL trigger: it works well and now I can enjoy my weekend )

  Thank you

• Rate the triggered loop of the timed iterations of TTL

  Hi all

  I have a camera control VI that awaits the shutter of the camera TTL information and use it as a source of synchronization for a timed loop. In this timed loop, the camera is read and analyzed. Program should respond as soon as possible a new image and that's why I put the timed loop to "Throw missing items" so that it does not seek to catch up (events im trying to detect is quite rare and last several frames).

  The problem is this: when I put the camera for a certain numebr of frameworks (e.g. 10,000) sometimes due to discarded frames ever loop iteration number the last number of frame expected and do not remove (it remains to 9.998 for example). I noticed I can stop it by deselecting "maintain phase." However, it is clear to me what happens exactly with these settings in a situation of TTL triggered.

  It is true that the loop passes the new data directly but starts the next loop the correct number of iteration (+ 1)? Or something else happening?

  IM grateful for any help!

  Dear j.win,

  If you deselect the option 'Maintain the Original Phase', in fact you never will reject any iteration, whatever the value "Discard missed items." On the contrary, the loop will try to catch up the iterations of the end.

  Use of a source of external synchronization (for example your TTL) instead of a source of internal synchronization does not change. You can use the 'period' entrance (dt) of the loop timed to specify when the loop is supposed to go (the unit is the "ticks" in the case of an external synchronization source). A value of '1' means that test loop to iterate over all the graduations of external synchronization source. If for any reason any iteration lasts longer than that, you'll have an iteration "end". Also with a value of '1', it is not possible to change the "phase", then the parameter "Initial Phase to maintain" will be defined only weather or not ignore you the iteration. If 'Maintain initial Phase' is set to false, the loop will run immediately after an end iteration to run always, but a little of the latter. If the 'Maintain initial Phase' is true, the loop will run immediately after an iteraion end if the option 'remove point missed' is false otherwise the loop will jump the iteration.

  It's more clear now?

  Kind regards

• digital analog arm start several triggers

  I trying to find out if there is a way to arm a trigger of labview to an analog signal and then actually have the trigger start from a separate, digital or analog signal.  Both signals came on 2 different channels simultaneously.  Research on the forums, I found that the opposite situation is possible: arm with a digital signal, then start with an analog-to-digital trigger but I have not found a way to either arm or take essentially the AND logic of the triggers two separate channels (with being analog and the other being is) as being the "ultimate" relaxation  Any help/advice is greatly appreciated.

  Hi, Bill Clinton.

  I think you are looking for the Signal VI to export. It can be found on the pallet of NOR-DAQmx. I've also attached a document with additional information on this VI.

• The TIFF to write IMAQ 2 - 1074396154 error occurs when saving a camera, but not two

  Hi all

  I have a program I customized based on example programs (e.g. triggered Grab loops producer-consumer) LabVIEW.  The VI allows the user to choose the number of cameras they would like to use for acquiring (between 1 and 4), as well as the trigger source - either a constant material counter or a manual release that is connected to a digital input.

  Acquisition works very well with any number of cameras (using a loop of producer), however I'm running on an issue to save images in the loop of the consumer.  Frames are removed during the registration process, when I have the 1, 3 or 4 cameras option selected.  I get error 1074396154: Image is not big enough for the operation.  This question is somewhat improved by hard-coding the size of the image of 1280 x 1024 (as suggested here), but a loss of image is still intermittent.  I never ran into this issue using the 2-camera option.

  I have attached my code here.  Anyone has any advice on why this error occurs only in some cases?  Is there a setting that I need to configure for IMAQdx?

  Many thanks in advance,

  Tracy

  Unfortunately the code is too big and can not look in every corner.

  -Coming from another question, IMAQ Create(User Buffer) creates the reference to the image.

  -You create an image to copy image to this place, you get from IMAQdx Grab.

  ->, You are able to see the image in indicator Camera1?

  -> Use your Get size vi after grab and internal image structure deal just before enqueueing and see if it is to have the image size valid.

  -Now let's say that if you get another picture before saving this image, then the image will be replaced.

  -So if your writing process is too slow, you must create the buffer sufficient user.

• Camera Basler slow to open a session

  I have 5 cameras scA1390 - Basler 17gm that were purchased at the same time. Four of them behave well, but is very slow to establish a session. I checked the IP configuration, and everything seems fine. MAC detects the camera and puts it on the listm, but whenever it is selected in MAX, or whenever a vi logs to him, the delay is approximately 20-30 seconds. All other cameras open sessions in less than a second. Once the session is open, the camera can be triggered and read very well. There is a configuration problem that could cause this delay?

  I think you could be right about that. I noticed a difference in firmware version in one of the cameras, but I am not absolutely certain that one. I'm away from them until next week, but I'll download the update and try when I can.

• external delay time on imaq camera

  Hi all

  Thanks in advance for any help. I'm sorry for display on such a common mistake, but I was not able to find examples or previous discussion forums that have solved my problem. Information in any form (examples, precedents, suggestions messages) are appreciated.

  My problem is that I can not manage to externally trigger the example attached "He'S triggered Ring.vi" without getting a timeout error.

  I was acquire images on a Dalsa 1 M 60 camera for a year using finite buffers, externally triggered, but the method of triggering that worked for me this last year is now a failed due to timeout error. I can confirm that my old program acquisition still work and physical relaxation is therefore able to reach the camera very well (g. trigger is identical to what I'm trying with the ring buffer).

  The error number is "1074397150 occurred at extracted IMAQ buffer. I spent the time-out of frame, added structures from sequence flat to make sure that things happen in a correct order separate counter in a separate while loop and has recently launched a campaign of the evolution of the parameters in the hope of getting lucky (I kid, but I get this desperate) randomly. I realize that this is probably due to a fundamental lapse in understanding on my part and I would appreciate anyone who can set me straight.

  Hello

  I am pleased to learn that the ring of triggering HL works. It is promising because it proves that the issue doesn't lie not with the framegrabber. I noticed one thing that is the default value, number of buffers in the HL triggered ring example is 10, while the default value is 5 in the low level version. Have you tried to increase the number of buffers in the low level program, and it allows you to run successfully?

• Camera not present error & Baumer GigE Test Packet (0xBFF69031)

  Hello

  I tried various fixes to other messages and still have problems setting up my TXG06 Baumer with LV running NOR-IMAQdx 4.0.

  The camera shows OK in the SDK of Baumer, but when you try to recover an image NI Max I get "the system has not received a test package...". "If I let MAX OR open and try the same device, sometimes I mistake"not present Camera. '... "instead, even if it is still running ok on the network.

  I added an exception to the windows firewall, enabled extended packages, tried to reduce the size of pcaket and tried without the Baumer software installed. Still no joy.

  Any help would be appreciated.

  Hi, noodles,

  It's quite strange, you seem to have tried all the troubleshooting steps that firstly, we recommend. How reduce you the size of packages to? Have you tried to set very low (~ 1 k) to see if even then you still cannot take a wink?

  What ethernet card are you using? (Just to be sure it's GigE) and have you tried this unit with another PC to see if the problem with your ethernet card?

• Capture camera IMAQ via DAQmx trigger operation

  Hi all

  I thought I could re - this poster in this forum to see if I get more ideas!

  I work with a PCIe-1427 card connected by link to a camera (SUI Goodrich) and also using a card PCI-6731 to which I attached a connection block M SCC-68 series.

  I managed to write code to control the .avi capture the camera and write separate code to control the lighting of optical switch connected to the SCC-68.

  The two lines of the optical switch Relay different info and I will in turn present this information to the camera for analysis.  Ideally, I'd like to trigger the acquisition of the capture of the camera with the optical switching so that each image contains information of a single channel only, but I still fell in the integration of the operation of DAQmx meter with IMAQ camera code.

  Is this possible?  I see 1 previous post by using a RTSI cable can I connect the two devices together (or alternatively use the DAQmx to produce a trigger on the digital).  Can someone offer information or an example on how to route signals via the RTSI to IMAQ DAQmx?  Also do I tuned regarding the generation of pulses to the switch that allows signals to pass through RTSI?

  I find it by running my camera and counter code in vi even both will work (not in sync)-if I connect the RTSI and select the camera settings to accept the RTSI triggers, if it was a simple solution?

  I would greatly appreciate any ideas you may have. my time runs out very quickly and is really distressing.

  Sincere greetings and thanks,

  Miika

  Miika salvation,

  If I understand what you try to do in VI you attached, you want the output of the counter of the task DAQ to serve the trig by buffer task it IMAQ via RTSI.

  To do this, use the property node of channel DAQmx to configure the output terminal of the impulse to be RTSI 0:

  Select property > counter output > Pulse > output terminal

  B. change the node property to write.

  C. create a constant and select/Dev1/RTSI0

  On your IMAQ configure Trigger VI, RTSI value as type, set to 0 the number of line, set the action to trigger each buffer and set the polarity to rising edge.

  Oh yes, make sure to connect the RTSI cable for two cards.  I forgot that before and felt really stupid later.
