• Look at the card and the reader at the same time?

  Are you able to listen to music from the sd card AND the reader at the same time? As the mixture between thbe reader and card? Or is it one or the other?

  Thank you kindly.

  Yes. If set to the random mode, for example, it selects randomly beaches/files of two memory slots.

• Can a module SCXI 1102 with a block of 1303 b cause some channels of reading of the voltage signals and other signals of current reading at the same time?

  Hello

  I'm trying to use two sensors of moisture Omega HX85BA and experience two CFI mass flowmeters in current loop. Humidity sensors have three outputs 0 - 10V, while flow meters have two outputs 4-20 Ma. Can I have all four sensors to wire to the same block of connection SCXI-1303 and read all the signals in the same VI? the block is connected to an SCXI 1102 b card and a 6052E DAQ of NI PCI card.

  Thanks in advance!

  Hello BBalmforth,

  Yes it can. Although you will need external resistances (I recommend resistors precision for better accuracy) for current signals. The SCXI 1102 b is indirectly measuring the current by measuring the voltage drop across the resistance. The table below describes the current diagram and how it will seek in LabVIEW and DAQ assistant.

• Is it possible for SocketChannel write and read at the same time?

  Hello
  
  May a SocketChannel simultaneously read and write?

  Yes. TCP/IP is a full-duplex protocol and therefore its Java application. Two of them.

  The only exception I know is weird where you use a SocketChannel in blocking via channels flow mode. These are internally synchronized probably on the channel itself, or at least a common object, so the reads and writes are synchronized between them. It is clearly a bug.

• Dimension 5150 305wt cannot use the CD-ROM and video card reader at the same time...

  OK, I bought my GeForce 8600GTS on my Dell Dimension 5150. It came with a power cable so I plug two supply cables optical drive into the video card, but if I plug in the power cable, I have no power to my cd player so I can't use it.

  The power of two male cable heads are not separated, they're attached to them, so I can not join just a head for the video card and the other on the cd player because it would not be long enough. I can buy a Belkin power extension cable, but I'm afraid that the power of cd drive will conflict with the power of the video card. I won't buy another power supply, because just to use my cd player. Any suggestions?

• Questions about serial port read and write at the same time

  Hi I create a user interface for the communication serial port, where there are essentially 2 front panels, where the user enters commands one and the other where the prints of UART is delivered. I thought initially using a state machine but the reading and writing may be independent sometimes and so I can't rely on States. I searched a bit on the forum and he left me even more confused. Help, please.

  (1) in a thread that sessions visa duplicated has been used for writing and reading at the same time, is it recommendable? How will this affect performance?

  (2) essentially when the vi is reading data are it must constantly view as well, however, someone said that it takes too much memory to use shift registers, so how do I go about this? If using a State in queue after the loop of reading it affects the playback loop and be sequential?

  In addition anyway is to move the cursor to the latest data from the indicator

  (3) for the control of the user input, assumes that the user has entered an order in the control and press ENTER, then writing visa is launched, but if it comes in another string and press enter then write must be called again... is - it possible? will detect the previous commands in the control of compensation?

  (4) according to my understand the expectation for the event do not monopolize resources and writing can go in parallel, am I right?

  Thank you. I have attached a very basic vi which took me to the point, but I want to make it more robust. Please help especially in the part of the user interface.

  su_a,

  (1) you can have only one session to a port. Several UART can handle full duplex so performance is not affected.  At flow rates of high data and large amounts of data, buffering and latencies of BONE can become a problem.

  (2) who told you that shift registers using too much memory? Shift registers are usually the best way to transfer data from one iteration to another. String concatenation inside a loop (registry to offset or not) causes the chain to develop and may require re-allocation of memory.  Your VI never clears the string so its cold length become very large.

  Generally, you do not have an active cursor on an indicator.  If you want to always display the most recently received characters and turn on the vertical scroll bar use a property node to keep scrolls to the bottom.  This can be annoying for users if they attempt to manually move the scroll bar and find that the program continues to move it back automatically.

  (3) if the user has changed the value in the chain of command, when he hits enter the modified value event fires.  Simply strike brace does not change the value and does not trigger the event.  Not control need to be erased, but the value that he has to change.  If you want to send the same command again, have a button send a command may be a better choice.

  (4) write is a case of the event.  It is not in parallel with anything.  The structure of the event do not monopolize resources.  The other loop will run while it waits.

  The event loop will not stop when you press the STOP button. Probably it wll take two command: change events of value after JUDGMENT before any loop stops.  Replace the Timeout event (which never expires) with a STOP: value change event and a real wire of this judgment to the Terminal endpoint.  Remove the local variable.  Make mechanical locking when released.

• Two fans at the same time come on the Satellite A30?

  Hello

  I ve just replaced my camera laptop mobo (2 fans) and I m sure that when I tested after all together put two fans of kicks in, but as I m sitting here write that I can t see or feed the second fan lights.

  I m worrying as when I took part I noticed that one of the connectors to the original fan was half way out - I guess it happened when I paid someone to repair my laptop, there is a year (I had to do it myself now and I ve felt m tech didn't know what he was doing) however I am a little concerned that maybe the second connector unit fan slipped out and this would explain why the second fan does not come when the first made?
  ID rather not disassemble it again to check if not I need to.

  Oh I've had a thought they are both controlled by temperature (they are of course) but are they set to start at different temperatures?

  Adding: chezybezy

  I m not an A30 owner but I guess that the two fans should start and run at the same time
  There are two power cables and I guess that both fans are ordered together at the same time

• Input module of data acquisition can be read by two or more LabVIEW vi at the same time % 3F

  I use the DAQ palette in LabVIEW to read the virtual channels of the input data acquisition module. I've done several VI who read many entries of three modules of simulations. The problem appears when I run two or more VI´s reading entries from the same virtual module (for example. first.VI module 1 input ai0 and second.VI bed ai0 entry module 1 bed), when this happens the next errors are shown:

  Error-50103

  Platform AND Services: The specified resource is reserved. The operation could not be performed as indicated.

  and

  Error-200022

  Resource requested by this task has already been reserved by another task.

  It's worrying because I want to get the DAQ chassis and some modules, but if this problem is present with physical equipment my application may be unnecessary. This means that entry module only can be read once at the time?

  I m using global variables in each Subvi to share data with main VI, however, I found the solution in a different way... I just changed to single channel and dbl sample playback mode, so I Don t need to clean up the task of reading in my subVI´s, the zeros isn´t problem here, and the six subVI´s work at the same time!

  Thanks for the tips!

• I want to open two different pdf documents and view them at the same time so I can read about everything by watching the other document.  I use Acrobat DC and whenever I open a document it creates a tab and I can only examine a document at a time.

  I want to open two different pdf documents and view them at the same time so I can read a whole watching the other document.  I use Acrobat DC and whenever I open a document, it creates a tab and I can only examine a document at a time. Is it possible to display two or more documents without having to toggle tabs?

  Don't think that will work, but you can drag the tab to a new window. Each window can have a set of tabs.

• Is it possible to see or read two video tracks at the same time?

  I have the video shot with two cameras at the same event.  If I took the video and put it in a sequence, say video1 video2, how can I watch two channels simultaneously so I can edit them?  I tried to use the multiple camera monitor and have this show video1, watching the video2 in the right panel, but it works very well.  I mean, that the multiple camera monitor does not play at the same time.  Instead, he stops, so when I play the other monitor is it still until I have stop it.  Then, it "catches up".  If I play the multi-monitor, the other is motionless until I have stop the monitor multi-cam.  Then, someone has a better solution that I can use where they both play at the same time?

  BTW, my hardware is new and I have a processor 6-core i7 - 3930K with 16 GB of memory, so I don't think that the problem is with my hardware is not not enough to properly run the Agency 5.0.

• Two applications at the same time on the M200?

  On the Amazon website (and I'm sure elsewhere), it says on the M200:
  "With the optional Tablet Multi Dock station, you can connect an external keyboard and monitor allowing you to run different applications on screens separated at the same time."
  I've been reading my M200 and the multidock and it doesn't say how to do this. It seems strange when it's supposed to be something special you can do with the M200, he's not telling how you do! Could someone enlighten me please?
  Thank you very much

  Hello

  In my view, this means that the option of extended desktop.
  If the external monitor is plugged so that you can use this option to enlarge the display option. This option, you can activate with the key FN + F5 combination. If this option is enabled for example, you can open two widows of IE and one from this window, you can switch to the external display. In this case, you can use two applications at the same time

• read the multiple analog inputs at the same time

  Hi all

  I use USB-6001 and want to develop an application to multiple tasks in C++. I try to read several analog inputs at the same time, but got some errors. To put it simply, I copy one of the sample code to read in analog data in a channel, and then turn it into function. Then I call this function to thread with the names of different poles (for example Dev1/ai0, Dev1/ai1) and I come across this error:

  "The specified source is reserved. The operation can not be specified such complete"code of State-50103

  I have search the forums, this may be because I use the hardware timing in this function, and this material timing cannot be used simultaneously by multiple tasks. I may have to put all the lines, I want to read in a single task (such as Dev1 / ai0:1). This way I can read two lines at the same time. However, when I try this, I encounter another error:

  Status code "buffer is too small to contain the data read" - 200299

  So here is my question, what should I do if I don't want to read the multiple analog inputs at the same time? Is the thing that hard time cannot be used by several true task? If I have to read several lines to a single task, how to set the settings?

  
  

• TCP Read and Write at the same time

  Hello everyone,

  I have a question about parallelism in TCP connections.

  I know that it is possible to read and write on the same connection ID.

  So, if you ReadTCP and WriteTCP block each other, if you use the same TCP connection ID?

  Or to request more precise if I run two while loops, in parallel, with one end by calling WriteTCP and the other called ReadTCP.

  one of the delay of loops (or block) will be the other if both loops call their VI TCP at the same time right?

  The system is Windows 7 and Labview 2012.

  Kind regards

  Sebastian

  They are perfectly parallel.  Just write in one and read it from the other.  There is no conflict.

  See My TCP articles for more details.

• NEITHER 9207 reading current and voltage at the same time channels

  I have a cDAQ-9178 chassis USB-three cards NI 9217 RTD, three cards 9263 0 - 10V and one the output OR 9207 16 channels analog card. What I m trying with this kind of things, is to read all the analog input channels (information of transducer, temperature, pressure, etc.) and adjust my controls to process with the analog output channels.

  My problem at the moment is the following:

  When I create tasks with DAQmx VI:s, how to create a task that reads current and voltage on the 9207 channels at the same time?

  When I created a task for RTD-channels (16), a task for the outputs analog 0 - 10V (12), a task for the analog input 4-20mA (8) and a single task analog 0 - 10V input (8) I get an error-50103. I think it s because the tasks of current entry and voltagge are trying to use the same CAD at the same time and LabVIEW informs that "The specified resource is reserved. Tasks are to leave so that the analog output task starts first, then I merged all clusters of the error and the rest of the task are started by an order to current input-> input-> RTD input voltage. I get this error after the current enter task started and enter voltage task begins.

  Because I m new on the LabVIEW and stuck in that time, I wanted to try the forum to find answers. I tried to find if someone else was having the same kind of problem, but with a quick search, there was none. I m in a bit of hurry, so I apologize if West a subject with a happy for that and I missed too much according to me.

  Really, the best way to do it is just adding 8 channels of voltage at a task, then 8-channel current, somewhat like this:

  

  Then spread over different channels when you read later:

  

  It should run without error.  It always is multiplexed to sampling, but it will be much faster to create two separate tasks.  There will be between 2ms (mode high speed) and 52ms (mode high resolution) between each playback channels, but it will still be much faster than the permutation of the tasks.
