• Using the Serial Port for data acquisition Non-Serial

  I searched the forums and can't find anything on this topic.

  I saw that it was possible to use the parallel port for e/s digital single and I was hoping that the serial port can be configured the same. It seems all VI VISA only to use the serial port to receive ASCII characters at a given flow rate, but is it possible to simply query the status of the line series at my own speed to see if it is high or low, kind of like a single pin DAQ?

  It seems that it would be possible until the serial data are read and controlled by labview, not Windows. Let me know if you have ideas of how to approach this problem, or any comment as to why it is not possible.

  Thank you all!

  Select the property > settings series > Modem of the line parameters. For example, the State of the CTS is an entry to the pc.

  With the help of these lines is a very poor substitute for a scope or map DAQ. The only things you can return is Asserted, Unknown or Unasserted. The range of acceptable signals is important enough. Anything between + 3 and -3 is an unknown state. Your other signals is + / 3 to 15 volts. What type of signals do you really want to capture?

  Edit: there is no such thing as a visa so I have no idea of what you actually use.

• How to set the number of packages to be send per second on the serial port in labview

  Hello.

  I need to send data to the serial port such that each data packet must be sent at a rate of 4 packets per second? How can it be done?

  Thanks and greetings

  What defines a package?

  You just need to have a while loop with a timer waiting for 250 milliseconds surrounding your VISA writing the function.

• whille prob get bytes to the serial port for serial communication

  Hi all

  I have one using the series write vi to send the command to the instrument. the answer I get is read NICU playback vi. I use between read and write the serial port bytes accumulate bytes. BU what I observed is quite strange. When I run the vi with the debugger, I could c the bytes to port series is 201 and what I get in buffer is only 133.

  any1 can guess at what the problem would be b?...

  You don't show the function of VISA set up a Serial Port, but I guess you have the active stop character. Playback will end automatically when the character is detected and you should never allow when you try to read hex.

• How to transfer files from PC to PC via a serial port using labview

  I need to transfer files (.txt, .doc, .xls) from PC to PC via a serial port using LabVIEW. Is it possible to transfer files, if so how to transfer?

  Yes, it is possible to transfer files with the serial port using LabVIEW.  The files are just collections of bytes and the serial port is good enough in the expedition of the bytes from one PC to another.  You must connect the ports series with a null modem cable.

  First, take a look at the example of serial communication.   In LabVIEW, go to the Help menu and select «Find examples...» ».  From there, you can search for "serial" or navigate to hardware input and output > series.  Select «Write series base» and Read.vi  Try this example to gain confidence on the serial communication methods.

  Then it's time to learn how to read and write files.  For this, the examples might be somewhat confusing as they deal with files that are presumed to have data of a specific type in them.  I would recommend just familiarize yourself with the functions in the file e/s palette.  Specifically, familiarize yourself with the following functions.

  1. Open/create/replace file - on the side of your destination, you will need to create the copy of the file you are trying to transfer
  2. Close the file - when you're done reading or writing to a file, you must close it.  It cleans the memory used and finalizes write operations that are still floating in the write buffer.
  3. Read a binary file - is the best way to play a file when you don't really like what type of file it.  In your case, you just want to get these read bytes and sent so they can be written down instead of destination.
  4. Write to a binary file - next to the destination, is what will store the bytes in the file that you created with the number 1.
  5. Size of the file get (under the range of the advanced features of file) - you need to know how big the file is, so you know when you are finished.

  OK, so once you are able to create files byte write and read bytes from existing files, you can move forward.

  I suggest the basic method is to have the user specify a source file on the source PC, and a folder on the destination computer.  Then find the size of the source file using the number 5.  Divide this number of size by the number of bytes that you want to transfer to the times.  The series pads are usually around 32 k (if I remember correctly) in order not to exceed that.  Now start to send data by reading a number of bytes and this string output wiring to the feature of writing VISAS.  On the side of destination, you will want to monitor the serial port for bytes and read when they arrive.  This string of yarn to the writing of the function of binary file to add them to your destination file.

  This is the basic outline of how to do it.  He needs to not to overload him write and read buffers on the serial ports.  Initially, you can use delays on the side sending to make sure that the side reading has enough time to digest.  To make things faster, you can bring in a control of flow.

  If all that sounds a little intimidating, there are there Alliance member companies (such as the automation of PrimeTest) who can write this code for you and even provides a turnkey for you solution.

  Happy wiring,

• The VI "VISA set up the Serial Port" will only work at 9600 baud

  I wrote a Serial Port RS232 RW.vi monitor of ' "which works for most. The problem is that it will not meet the alternative port configuration settings... For example: the default RS232 serial port configuration is:

  (COM1, 9600 baud, 8 data bits, 1 stop bit, no without parity)

  As a test, I use a Null Modem cable to connect to my LabView Com1 port to another PC running RealTerm Serial Port Monitor... Using my "RW.vi RS232' newly designed with the port settings of (COM1, 9600 baud, 8 data bits, 1 stop bit, no without parity), I can send and cannot receive data back throughout the day no problem...

  However, if I configure the port "RW.vi RS232" all other configurations, such as (COM1, 2400 baud, 7 data, 1 stop bit, odd parity bits)... He will not take the expected risks and continues to operate @ 9600 baud rate etc.

  Then, I changed the settings default "RS232 RW.vi" (2400,7,1, Odd)

  He still refuses to derogate (COM1, 9600,8,1, no...)

  I also went in the Device Manager of Win XP on the system of LabView and configured manually Com1 2400,7,1, Odd

  and yet,... work at the "RS232 RW.vi" @ 9600,8,1, none

  Everyone can test my VI in the car and see if they have the same problem of not being able to see the new changes in the Port configuration settings... other than (COM1, 9600,8,1, no...)...?

  FYI... Unfortunately my LabView runs on Version 6.0, you may need to up-conversion of the attached vi

  Instead of simply appreciate the comments, you need to implement.

  Having closed VISA inside the loop is definitely the problem.  And Crossrulz is 100% correct about the problem being that the serial port gets zero to default baud rate after the closure of the port.  Here's the proof.

  

  Note that while may have set the port settings manually in the Device Manager, these parameters are reviewed by the pilot VISA.  If you look in the measurement and Automation Explorer under devices and Interfaces > serial and Parallel, you'll see the default settings using the VISA driver.  If you change this setting, your program will work as desired.  But this is not the appropriate fix.  The correct solution is to get the VISA close out of the while loop.

  The port settings are established in this order.

  1. by Windows device drivers.

  2. by the VISA driver as set in MAX.  Since you are using VISA, these settings will be automatically replace #1.

  3. by the port settings, you set programmatically in your LabVIEW program.

• Part number for the serial port in option HP Z420

  I am looking for the serial port in option for the HP Workstation Z420, but in a datasheet, it is only mentioned as an optional serial port kit.

  What is the number on the right side of the product? The same for the workstation Z400 was PA716A, but it was not compatible with the new workstation model...

  I used the same part number, I used to model Z400 and it seems to work well.
  HP code is PA716A.

• level of tension for the serial port sbRIO

  What are the levels of RS - 232 votage on sbRIO serial ports?  Signal levels might be: 3.3 V, ± 5 V, ± 10 V, ±12 V and ± 15 V?   ±12 v what I often see for a direct connection to the serial port of a PC.

  Hi Matthew,

  The signal levels to the sbRIO-9605/06/23/26/33/36 are ±5V. I took a quick screenshot of TX W.R.T. GND. Tensions in the data sheet the standard ±5.4V (typical) loading with 3 k and a minum of ±5.0V. The RS-232 standard can accept a pretty big swing however (-3V to-25V) and (+ 3V to + 25V) for two levels of logic. The screen was shot I took with a unloadeed line so the voltage levels appear to be higher than most.

  The transceiver set used is the MAX3243.

• 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.

• Read the Serial Port in case of break in series

  Hello world

  I want to create a VI who will write a series, write interruption, then wait for an interrupt series to be received and if it is received, read what's on the serial port.  However I can't the VI to detect that an interruption of the series took place.  I looked at and followed what was done in the "Detect the Event.vi Break" example in examples of Labview.  The microphone that speaks to the VI sends a break of 13 bits (approximately length 57us), as expected, proved by the use of an oscilloscope but Labview is not contagious. I have attached the VI in question.  It is used as a subvi in a larger program.  I'm missing something or doing something wrong?

  I do not know.  230 400 is a very fast pace.  The UART in the PC isn't really in the game, but the EasySync USB/serial box is what is the factor.  USB is part of the communication may be adding a few complications.  You may browse the EasySync detailed technical data to see if they talk about it.

  I would certainly try a very long break first.  If it works, then start working backwards to small jumps.  If a long pause does not work, then you know that perhaps the problem is elsewhere.

• Sometimes the lost bytes, reading the serial port

  Hello!

  I'm reading the serial port data (flow rate 57600 baud rate) that works very reliable so that I do not open any other window

  or minimize/restore my window of the application during the program is running. Then a byte of incoming data will be lost.

  I get a string of 30 bytes each 50 m in most of the cases the first byte is lost, sometimes one in the middle.

  This occurs not only on a PC.

  Is this a problem of LabVIEW or Windows?

  Are there settings that can solve the problem?

  Best regards

  JK78

  I solved the problem.  

  There was a bug in my program who become visible only if a window has been reduced or restored.

  When there are two or more messages in the buffer VISA, the separation of the messages was incorrect.

  Array index corresponded to false so that the first byte of the second message was at the end of the first

  and so the second message in the buffer seemed incomplete.

  In normal operation, the playback loop runs so fast, never both messages are in the buffer.

  Thanks for all replies.

  JK78

  Either way, I work with LabVIEW 2009 and serial interface hardware motherboard. With XON/XOFF flow control

  is not possible in my application because all the hex values from 00 h to FFh may appear in a message.

• Problem using the serial port with windows 7

  Hello

  I have a modem of SIM cards (used to update remote controller of the electronic gate) that connects to my computer via the serieal port (COM1).

  The modem comes with its own piece of software that worked fine on my old computer with windows 7 (I had a similar problem, but then I just need to update the driver).

  I now have a new computer and I am unable to connect using the modem (I think I'm using the latest drivers for the serial port).

  Is it possible that I need an older version? If so, how can I get a?

  My motherboard is a GIGABYTE H81M-D2V.

  Any ideas?

  Thank you

  AVI

  Hi Avi,

  Thank you for the update on the issue.

  The UART, or Universal Asynchronous Receiver / Transmitter, is a characteristic of your microcontroller useful to connect serial data (text, numbers, etc.) to your PC. The unit switches incoming parallel information (in the microcontroller/PC) to series data that can be sent over a communication line.

  According to the description you provided it seems that your modem isn't connecting with your Windows 7 computer, then I would contact Duetech Berès your modem manufacturer, so that they provide you with the steps to set it up.

  Get back to us after contacting them and please get back to us with your question was last updated.

  Kind regards.
