Send and receive data via the Ethernet Port?

Hello

I am trying to acquire details of LAN/Ethernet from the PC through LabVIEW.Like details, we get the date & time, etc Serial Port system, is it possible to get the details of my PC via LabVIEW.My LAN aims to sebd and Receive via Ethernet Port command.

The last time I did it, I used the range of tcp. (I go ctrl + space for quick menu then type tcp). Open a connection to the network device, and then use tcp read/write, depending on the case. There are examples that can be very useful

Dennis has already said: for a direct PC - PC connection, you need a cross over cable. If you connect through a router or a switch, you use a standard cable.

You elected probably still use the protocol HTTPS for Hotmail. If you did, this means that WLMail cannot connect to Hotmail via HTTP using DeltaSync. Go to https://account.live.com/managessl and log in with the account which does not work in WLMail. See the important note, and then select do not automatically use the HTTPS protocol and Save.

How to periodically send various types of data via the Serial Port?

Hello! Everyone

I have to send data to LabVIEW to my device on the Serial Port.

I know how to send data on serial port in LABVIEW, I already have this part.

Now the problem is that I have several types of data I need to question my embedded device, if I want to send the query periodically command.

So lets say that my four Op Codes are the following, which will send four different types of query command to my device on the serial port.

(To be honest only OP_LED and OP_SENSOR is used now)

0, OP_SYNC

1, OP_LED

2, OP_SENSOR

3, OP_FUTURE

Structure of basic package is as follows:

Header (0x2C), Checksum, length of the data (n bytes), Op_Code (1 byte), length (length of Code + data Op)

For OP_LED, I need to send the package as follows:

0x2c 0x02 0x01 0 x 00 0x2F (0x2F being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

Length of the package this is 0x02

0x01 is Op Code for OP_LED

In the same way

For OP_SENSORi need to send the package as follows:

0x2c 0x03 0x02 0x00 0 x 00 0x2D (0x2D being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

0x03 is length of packet here

0x02 is Op Code for OP_SENSOR

So, how can I do this periodically in labview, in such sort that period can be adjusted whenever necessary.

Is there something in LabVIEW to do.

I had done the reception and decoding part and working properly.

http://forums.NI.com/T5/LabVIEW/store-data-coming-from-serial-port-in-buffer-and-then-take/m-p/32722...

So I must implement read and write the part of same while loop?

Do not insert in the table if you put data in an array at index 0. Just use array to build.

No need to have Visa to write don't be a part of wire to the wire of reference and error VISA go in the upper part. These wires should go THROUGH the entry VISA.

Don't your checksum requires all the bytes up through data? Righ now, you only put the checksum on data bytes and forget the opcode and length bytes.

Your sending is not the opcode for Opsync or Opfuture. You just send the empty tables. At the same time for the other two, you put the opcode in the data table. All your original opcode in the table build thread. Get the data out of these structures in case item which is supposed to represent the opcode.

xpress_embedo wrote:
Now it works but I have now two problems.

(1) OP_SYNC and OP_FUTURE do not data, but still receive its data on serial port, can I do something here as I have nothing when the table is empty in the structure of the case.

I do not understand this statement. Perhaps my answer above will fix any issue you have here.

(2) how can selection operation Code to be send is done using control façade but real application, this task should be automated to a certain frequency, like OP_LED package must go out to the serial port to 100msec and packet OP_SENSOR must go out to 1000msec, I do this.

Now you agree a little more architecture. I would encapsulate the code that is in the while loop as a Subvi. Then with the hand of your program while loop, use two time Express VI, a game for 100 msec, the other for 1000 msec. When an express VI is true, run the Subvi with a command set waiting for the answer. When the other VI Express is true, have it run the Subvi with the other set of commands.

The device responds with anything when you send these commands? You only send data. I see no VISA Read to be able to recover all the data.

Send and receive data packets on the network

Hi all.

Let's say I have a GPRS Modem that sends a data packet to an IP address of a server.

How can I receive and read the packet data using Labview?

In other words, how can I send a packet of data to the server using Labview?

Thank you.

Dear UOI,

First of all, in my opinion, you must decide which protocol you we will use to connect both sides of the application.

Is that UDP or TCP, for example?

Reading of the package depends on the Protocol, according to me. But it is possible.

About these two examples of Protocol that I quoted, that's two white papers for you to analyze.

Sending and receiving data PIC18F4550

OK, I have seen some forums on the way to talk with the LabView PIC18F4550 and did not find any solution up there, usually all the subjects this is ended with nothing.

OK, here's what I've done so far:

Part of microcontroller: I have downloaded the example of the Microchip Solutions, compiled the example for PICDEM card, however I have no card PICDEM, so I just set up my own simple Board with minimum elements. I have run this example on my PIC18F4550 and also used the standard Human Interface Device driver, I have run the example application and could turn on/off the LEDs and read potentiometer values. Then, once I saw that the device is working, I uninstalled the driver and unplugged my USB device.

Now: I found the manual on the site of NOR, which explains how to generate the pilot tool of NI-VISA, I went through it, and with generated success driver for my device and then I installed this driver, plugged my USB with PEAK and could see its properties etc.

So far seems ok. Now appears as a last step, I want to read data let the potentiometer through the PEAK.

According to the previous manual, now I use VISA Interactive Control tools, what im going to do now is to send requests to my PIC and get response/data from it.

Take a look at some of the code of the firmware on my PIC:

Sub ProcessIO (void)

{

    Blink the LEDS according to the status of the USB device

    If (blinkStatusValid)

    {

        BlinkUSBStatus();

    }
Tasks user Application USB

    < configured_state)||(usbsuspendcontrol="=1))">
If (!.) HIDRxHandleBusy (USBOutHandle))				//Check if data received from the host.

    {

        Switch(ReceivedDataBuffer[0])				//Look the host data sent, to see what kind of application specific command, he sent.

        {

            0 x 80-case:  //Toggle control LED

		        blinkStatusValid = FALSE;			Stop the flashing of the LED automatically, will now control manually.

                If (mGetLED_1 () == mGetLED_2())

                {

                    mLED_1_Toggle();

                    mLED_2_Toggle();

                }

                on the other

                {

                    If (mGetLED_1 ())

                    {

                        mLED_2_On();

                    }

                    on the other

                    {

                        mLED_2_Off();

                    }

                }

                break;

            0 x 81-case:  //Get State of push button

                ToSendDataBuffer [0] = 0x81;				Back to the PC host the command echo we assume in the first byte.  In this case, the command Get Pushbutton State.

				if(SW3 == 1)							//pushbutton no hurry, the pull up resistance on the circuit board is pulling on the high PORT pin

				{

					ToSendDataBuffer [1] = 0x01;

				}

				else									//sw3 should be == 0, push-button is pressed and overwhelming pull upward resistance

				{

					ToSendDataBuffer [1] = 0x00;

				}

                If (!.) HIDTxHandleBusy (USBInHandle))

                {

                    USBInHandle = HIDTxPacket (HID_EP,(BYTE*) & ToSendDataBuffer [0], 64);

                }

                break;
0 x 37-case:	command /Read. POT  Use ADC to measure an analog voltage on one of the pins of I/o ANxx and returns the result to the host

                {

                    WORD_VAL w;
If (!.) HIDTxHandleBusy (USBInHandle))

	                {

	                    mInitPOT();

	                    w = ReadPOT();					ADC lets read the pin I/O voltage.  See the relevant HardwareProfile - the stem of I/O that it will measure in the xxxxx.h file.

														Some advice from demo, as the Council PIC18F87J50 FS USB plug-in Module, do not have a potentiometer (when used stand-alone).

														This function call will always make however the analog voltage on the I/O pin.  To make the demonstration more interesting, it

														suggests that an external adjustable analog voltage must be applied to this PIN.

ToSendDataBuffer [0] = 0 x 37; Back to host the command echo we assume in the first byte. In this case, the command Read POT (analog voltage).
ToSendDataBuffer [1] = w.v [0]; Measure the analog voltage LSB
ToSendDataBuffer [2] = w.v [1]; Measure the analog voltage MSB

USBInHandle = HIDTxPacket (HID_EP,(BYTE*) & ToSendDataBuffer [0], 64);
}
}
break;
}
Rearm OUT for the next package endpoint
USBOutHandle = HIDRxPacket (HID_EP,(BYTE*) & ReceivedDataBuffer, 64);
}

} //end ProcessIO

As you can see he is ProcessIO function, with the presentation of the main switch, for example case 0 x 37: means if it gets this value from the host, it must send the value of the potentiometer to USB.

Now, what I tried to do is, in the interactive control of VISA, I selected the tab Interface IO and then tried to send the query with the value 0 x 37 in the field of the wValue, the bmRequestType was 0 x 0, and what I get is weird values I don't think that are the actual values of the potentiometer read... (I tried to change the potentiometer then do ask again and got the same values)

I also tried to experiment with basic i/o tab and got the same weird things...

so at this point, what I am doing wrong? what I need to / supposed to do now?

or can u point me to the source of valuable information?

or the LabView guru on this site, tell me please your opinion on this subject?

read and receive data from the server

Hi all

I want to develop an application that extract data related to the content of the server, how to do? I read somewhere stating this task requires sdk server push? is it possible do not use push sdk server and the server reading so that I don't have install anyting from the server.

Your Web service code decides how much data you send or receive from the customer.

For example, you can have a Web service method, which returns records to a particular date, then you must create a web service method that accepts a date to a string as a parameter and a request for service records of server request, write resultset in encoding (like xml, json, etc) and return this string as a response to the client client will read the data as a byte array, then converts the byte array to the string and according to the encoding defined by service will analyze data of interest.

How do I receive audio via the DVI port?

Hello.

I have a HP Pavilion p6-2378, that I use as a PC Home Theather. The motherboard on this model lacks an HDMI port, which is how the rest of my system connects. I use a HDMI-DVI adapter and video works perfectly, but there is no audio data. Several people told me that the sound signal can transmit through the DVI port. Y at - it a setting or a software that I have to make it work?

Thank you.

Hello

This article could make interesting reading.

As suggested above by Paul, use a discrete videocard with HDMI.

That said, this account has ever worked? I use Cox on the West Coast and I use port 110 for the outgoing. Port 25 for incoming. And SSL is not checked here.

Is a person with problems with their new 6s more iPhone send and receive pictures via SMS? Even if I'm on WIFI, I have my cellular data button turned to receive a picture. Then in turn instead to use WIFI, it devours my data plan. If to halfway through the month I get warnings that my data plan has almost disappeared. I did everything, including resetting the phone to factory settings. It also does not send a text if IMessage is turned on. It switches immediately to Imessaging which of course, again use my data plan. Of course, I could use some help with this. BTW, my text messaging service is connected to my phone number and not my email. Who was one of the suggestions that support Apple told me to check. Never in my life have had so many problems with a phone since I bought this iphone 6 s.

SMS is a function of the carrier, you will need to contact your cell phone provider and see what is the matter.

IMessage uses very little data.

UDP communication via secondary ethernet port on the cRIO-9074 problem.

Hi guys.

I connected my host pc running LV 2010 my cRIO-9074 port using a main ethernet crossover cable. I want to use the second port ethernet on the cRIO-9074 to read UDP messages, and I want to access these messages on my host. UDP messages are sent from a local network, but for testing I also use a second pc running LV 2010 to send UDP messages.

I configured the ethernet on the cRIO-9074 ports according to this tutorial: "knowledge base 4E0DGASK: Configure the Ports of double Ethernet on real-time controllers'." " My host and primary ethernet port belong to 'Subnet A' while the second port and the second computer, sending UDP messages belong to 'Subnet B' (at the end of my post I will list the masks of ip addresses and the subnet).

For simplicity, I used the VI´s of this example as a basis for UDP communication. The "UDPServerOnRemoteTarget.vi", which broadcast messages UDP, will run on the secondary computer. The "UDPClientOnRemoteTarget.vi", which reads messages UDP, will work on my host pc.

Now, in the 'UDPServerOnRemoteTarget' VI, you must specify two IP addresses (port # remained unchanged at 3363):

1: the IP address of the ethernet port that will be broadcast UDP messages.

2: the IP address of the ethernet port that will receive the messages.

In the #1 case I put the IP address to the IP address of the ethernet on the secondary pc port.

At the #2 I tried to set the intellectual property: a) IP address of the secondary ethernet port on the cRIO, b) IP address of the ethernet on my host computer port and c) IP address of the primary ethernet port on the cRIO.

None of the parameters produced results. I also tried to change the port number, which did not help.

However, if I bypass the cRIO and connect the host pc and the secondary computer directly (by using a cable crossed a regular cat5 ethernet cable), I am able to send and receive UDP messages (the two stand-alone always are on different subnets). I guess that this at least excludes any fault in the VI´s code.

Does anyone know what I'm doing wrong here? Is it possible at all to read the UDP messages that are sent to the secondary ethernet port on the cRIO my host pc?

I have searched the entire site OR and forums, but didn't come through all that solved my problem. Most of the other tutorials configuration resembling my case is to import the device sends UDP messages in the project, but which is clearly not possible in my case, or is it?

My IP settings are:

cRIO 9074:

Primary ethernet port: 169.254.62.215

Secondary ethernet port: 192.168.0.102 (static)

Host PC: 169.254.58.4

Secondary PC: 192.168.0.144 (static)

SubnetMask on all ports are the value 255.255.0.0

I hope someone out there can help me out.

Kind regards

Phat

Solved.

Stupid mistake. I was running the VI on the host instead of the cRIO pc, which explains why direct communication between the computers worked. Everything works well when it is compiled for the cRIO.

Kind regards

Is it possible to send and receive RTP streams on the same computer?
Hi all

I tried sending an RTP stream and receive it on the same computer, but it did not work. I use the AVTransmit2 and AVReceive2 classes, I assumed that these classes are popular, so I have not included the code for them) for this.

It works perfectly fine when a computer sends using AVTransmit2 and another receiver using AVReceive2. However, when, on the same computer, I get the following error in AVReceive2:
```
 Cannot create the RTP Session: Unrecognized Windows Sockets error: 0: Cannot bind 
```
The address I used for transmission and reception is: 224.144.251.104/22200

And I also discovered that it IS possible to send and receive streams on the same computer using JMStudio, but I found it very hard to dissect its code.
How can this be achieved using these two classes, that is, the AVTransmit2 and the AVReceive2?

Any suggestions will be greatly appreciated.
```
private String createTransmitter() {
...
localAddr = new SessionAddress( InetAddress.getLocalHost(), port);
destAddr = new SessionAddress( ipAddr, port);
```
You can do this instead:
```
localAddr = new SessionAddress( InetAddress.getLocalHost(), SessionAddress.ANY_PORT);
```

Unable to send or receive files via bluetooth.

Hey guys, I have a Microsoft bluetooth - the transceiver v3.0 Bluetooth dongle. This dongle came with my entire keyboard and mouse (Wireless Laser Mouse 8000 and Wireless Entertainment Keyboard 7000). In any case, before, when I was with Vista, I could send and receive files via bluetooth dongle.

After the upgrade to Windows 7 Home Premium 64-bit, I can't do it, but I'm still able to pair my mouse and keyboard for it. When I try to send a file, this message pops up: "Windows could not transfer files. The file could not be sent because the connection could not be established. Make sure the Bluetooth radio is plugged. To try again, click the back arrow. »

I uninstalled and reinstalled the software IntelliPoint/IntelliTypePro, which would be to reinstall the driver from the transceiver, but the problem persists. In Device Manager, bluetooth radios does not appear.

Can anyone help me please with this problem?

I posted it.

Hello

Eventually the large amount of data that occurs during the influences of P2P file sharing or Skype session of the internet connection.

Sometimes this question is displayed on my laptop if 2 or three laptops are connected to the same router.

However, have you tried a few solutions stallions like WLan driver updated for example?

Please check the Toshiba Wlan portal and install the latest version of the driver:
