How to send signal generated by labview to router?

the singal can be '0' / '1'

Since it sounds like you are just doing some simple network communication you should not have to communicate directly with the router. The network will take care of routing your data around by itself. You will probably need to use either TCP or UDP to communicate with the adruino. You will need to get the protocol it is using to determine how to communicate with it.

How interface N5181A MXG signal generator with labview by using LAN Interface????????????

hai every one ...i have a doubt how to interface N5181A MXG signal Generator with Labview by using LAN Interface???? and
how to find IP Address of N5181A MXG signal Generator????????
when i connect instrument with labview it shows that no instrument connected and what are the requirements for LAN interfacing with that instruments in labview and please help me??????

You can set the IP Address on the instrument. You may need to be in the same subnet of your controlling computer, so you may need to set your computer's IP Address to something static.
Use VISA. It makes life easier if you decide to use another bus (like GPIB, USB, serial, etc). In MAX, create a network session with the static IP address you set the instrument to and use that as the VISA Resource.

How to send IP pacekts by LabVIEW RT

In a project,I use PXT RT controler and cRIO , need send IP packets to communicate with other PCs.
I can use raw socket to send IP packets on the Windows,how to send IP pacekts on the Pharlap and Vxworks by by LabVIEW RT?
There is somebody can help me ,thank you very much.

Different methods of communicating between a VI on a Real-time target (RT PXI, cRIO) and a VI on Windows are outlined in Real-Time VI to Host VI Communication Methods. One of them is TCP communication, which sounds like the solution you're looking for (there are examples in the Example Finder). However, if you can get away with using shared variables, I'd recommend using them out of simplicity (you can flatten and unflatten to/from string or variant data types if necessary).
Good luck!

Forms 10g, how to send ReportServer generated PDF directly to client printr

Hi
We are implementing Forms 10g now, at we are facing quite a big problem - we haven't found a way how to send Report Server generated PDF directly to printer installed in clients computer.
Forms 10g and ReportServer are installed in the same machine and clients are accessing Forms10g through IE. Installing all the printers to the Forms10g server is not an option!
Is there any way of doing it?
Probably we could write a java bean that can read in the byte array and directly somehow send it to clients printer(java can read client printer list) but at this moment I have no idea how to accomplish it - haven't investigated it yet.
So if anyone has working software, please let me know how you achieved it.
Thanks!

may be this will help

Thanks for any help.
Regards.Try a package named: JTwain, which is available at http://asprise.com/product/jtwain.
JTwain supports all kinds of digital cameras and scanners.
You can use Java to access, contorl digital cameras and scanners, and of course,
to acquire images with flexible settings.
The developers' guide is available @ http://asprise.com/product/jtwain/devGuide.php
Here is the sample code:
try {
   // the SourceManager manages and controls all the data(image) sources, eg. scanners, digital cameras,
   Source source = SourceManager.instance().getDefaultSource();
   source.open();
   // Enables or disables the UI
   source.setUIEnabled(false);
   Image image = source.acuqireImage();
   ... // Uses image here ...
   // Saves the image into a file
   source.saveLastAcquiredImageIntoFile("test.jpg");
}catch(Exception e) {
   e.printStackTrace();
}finally{
   SourceManager.closeSourceManager();
}Good luck!

Communicating with HP signal Generator through labVIEW

Hi I need to know the Command String for recieving a numbered string from an HP function Generator which is comma delimetered and can be used to plot a graph in labVIEW 7.1. It would be usefull if I could also get the command string to recieve the same result from an Agilent Oscilloscope. I have tried several recommended command strings, however all of them return an error. Any help would be greatly appreciated!! Thank you

How can anyone provide you with the command for an instrument when you don't even mention the model of the instrument.
Do you have the instrument manuals? The commands are all listed there and if you don't have the manual, go to www.agilent.com and do a search for them. Have you tried to find a driver for the instruments? NI has thousands of drivers already written. Go to http://www.ni.com/devzone/idnet/ and search.

How to send a path from labview to teststand.

Hi!
I have a DLL that I have developed in LabView and as a input parameter I have a path to a file
but if I in the LabViewCode uses String to recieve the path from TestStand and the path includes \T
these just disapperes.
ex:
I send "C:\test.vi" to LabView from Teststand
If I check the Path recieved in LabView i get "C: est.vi"
Instead if I in LabView uses Path to recieve data from TestStand I get an error in Teststand.
How should I do?
/Andreas

Labview strings use the backslash "\" as a special character. \t is a tab, \n is a newline, \r is carriage return, and so on. To send a real backslash use two of them, like \\. So your path string should be "C:\\test.vi".

How to send signal out from PCI 6010

I'm using signal express 2010 liecensed version. Now I want to create an AC signal and send it via NI PCI 6010 to servo motor. I tried many time, but it does not work. I click the example, signal express is automatically closed. Pls help.

I'm using signal express 2010 to create an AC signal. The AC signal is created initially. Now I want to send it via NI PCI 6010 to control pulse width modulation, for example. The problem is: i cannot get the connection diagram. I don't know how to use the help. Everytime I tried to open the example files, the signal express off itself automatically. Its a licensed version.
I need examples to know how to create a signal, then send it via Analog Output. I don't get the CB-37F-LP Quick Reference Label in internet. So I don't know which pin is given for AO1 and AO2.
I'm also using another computer with signal express 2009, PCI 6221 with SCB -68 connector. The connector has legend to tell which pin is given for analog output. Whereas the CB-37F-LP has nothing to indicate the connections. However the NI PCI 6010 can acquire signal as I have tried in few cases.
Now I need an example to know : HOW TO CREATE A SIGNAL AND SEND IT VIA ANALOG OUTPUT.
Pls help me.

How to send chr$(195) in Labview (MAX)

I have an elderly Philips DMM that needs re-calibrating, using the GPIB commands. I need to send it a character string starting with CHR$(195). I have a GPIB-USB-HS interface and run Labview 9. To get me going I have been using the Measurement and Automation Tool. Sorry this is a newbie question but I can't find the answer. Thanks

How to send multicast message from PC to router to start multicast

Dear All
I have a PC and I want to send the video message out through multicast from the PC. Do you think I need to have some special tool installed in the PC to start the multicast ? The PC is directly connected with a router
Thank you
Frank

Hi Frank,
You are welcome.
To sum up basic configuration rules for your network as simply as possible to make the multicast fly:
You need to have an IGP protocol running (OSPF, EIGRP, IS-IS, RIP) on all your routers and make sure that all networks are duly advertised, both the network where the source streamer is, and the networks where the recipients are located. I suppose you already have this.
All routers in your network need to be configured with ip multicast-routing global configuration command.
All interfaces on all routers in your network need to be configured with ip pim dense-mode interface level command.
By this, I am suggesting that you run a simple, if somewhat inefficient, version of multicast routing in your network, the so-called PIM Dense Mode. More preferred version of multicast would be PIM Sparse Mode but that one is slightly more difficult to properly configure and troubleshoot so let's start with the simplest option and test whether it works.
Once again, be careful to configure all your routers with ip multicast-routing (it's not sufficient to configure just the first or the last router with this command - all routers on the path between the source and receivers need to use this command) and ip pim dense-mode (all interfaces on these routers, both "upstream" interfaces going back to the source, and "downstream" interfaces going toward the receivers).
Best regards,
Peter

How to get controls of a vi to send signals more than once

Hi,
Recently I designed a rather neat VI that allows the user to quickly switch wiring and ID number characteristics on a certain device. The inside of the VI is an orchestration of sequences and loops that allows user full control through one control loop that cycles through until the user selects a desired function, for which the loop terminates and performs the function. After the function is complete, if the user has not pressed "stop", another loop brings the program back to the control loop.
So the VI works great, but as someone who's been interested in automation, I want to try to take this to the next level.
My next attempt was to put the finished VI as a sub-VI in a new VI that is meant to automate the user control process on the front panel. I've attempted to use both a flat sequence and the state machine template to do this, and they work great for automatically pressing buttons when working with property nodes or local variable. The problem, I've found, is that I don't know how to send signals to the Sub-VI from the connected controls at a constant rate without throwing it into a loop itself, which doesn't work because, of course, the sub-vi runs on it's own set of loops and there will be no iteration increment until the program inside the sub-vi terminates.
Or, if the VI and it's inputs are left on it's own and I try to write values to the controls of the inputs, I can definitely change button positions, but, looking at the signal flows, no signal will be sent from the connected controls to the sub-vi.
A second problem is that, due to my use of a program button that latches when pressed, I'm having a tough time trying to manipulate it will local variables or property nodes. Because of the way it functions, the "value" property nodes shows up as purple and I'm not sure how to make it tap itself to operate how it did in the Sub-VI.
Thanks in advance,
Matt

Well, a tight polling loop is typically not a good design. have you tried the event structure instead?

You can wire control references to the subVI and then poll the state of the controls on the toplevel VI via value properties.

Of course you need to call the subVI from a parallel loop (for example) so other parts of the code don't get blocked.

Latch booleans are not compatible with locals and value properties. A latch action boolean turns true until it is read by the code. If you were allowed to read (and reset it) it from multiple locations and via multiple mechanisms, you would get completely unpredictable code. You can always use switch action booleans and simulate latch action as needed using e.g. local variables.
It is difficult to give more specific comments without seeing the code. What are the subVIs doing? Are they interactive too?
If you don't mind attach your code and we will give more specific advice.
