• 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.

• 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

  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.

• 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.

• 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.

• Using the Serial Port on the HP 50 g graphic calculator

  Hello world

  I have another question. I want to use the Serial Port on the HP 50 g to connect with another device. The device is called the MFJ-1214PC. What it does is to accept the text and commands through a 9-pin serial Port and converts the text in a Code Morse/RTTY sound audible. It also decodes Audible the Morse Code and RTTY radio signals and displays them as text on your computer. The program that controls the MFJ-1214PC was originally written for an IBM PC for the MS-DOS operating system. The HP 50 g graphic calculator meets the system requirements for the simplest version of the program. I was wondering if there is an MS-DOS emulator written for the HP 50 g, which would allow the HP 50 g to become the computer in this case, or if the program could be rewritten and brought to the HP 50 g. If it could be rewritten, programming language what do you think would be better suited to this type of application (if it is even possible?) or UserRPL, SystemRPL or Assembly. Don't forget that I'm a complete newbie with the HP50g and have never programmed with it yet. I'll include the manual of the MFJ-1214 PC as an attachment so that you won't have to look for him. Thank you in advance for your help!

  ~ Zekelegge ~.

  I understand (from my brief overview) out of the box-MFJ-1214PC, this offer box decoder output series computer.  The computer (50g in your case) will have the software to read message series and then convert that to an output for display.

  BartDb gave you the right answer.

  A serial cable with the correct speed level and reversing lever to manage as well as the 50G has a RS-232 signal to the outside world is the ideal solution.

  However, make sure that the output of the decoder box series package can be understood by the 50 g. aud, bits, etc.   (you have the set-top box manual, so you'll have to look that up)

  the streamsmart is not an aggregator of serial port.

  in other words, these connectors DIN of Qty 4 on the front do not accept series rs-232 input and send then to 50 G.

  I'm not an expert, streamsmart more info on these boxes is rare to find.  The probes are even more rare.

  However, I know that the 4 connectors are for the analog-to-digital conversion in the probes.  The streamsmart works as a "data logger" in which he sees the input probe, the A/D converted, then sends it to the 50G (or a computer via the USB port).

  In addition to the solution of Bart, there was another named Tiwag forum poster who created a serial cable and displayed a schematic representation of the cable.  This information can be found here:

  https://groups.Google.com/Forum/?fromgroups#! searchIn/comp.sys.HP48/serial$20port/comp.sys.HP48/ltcane1jSOw/uHyw2Ti03kgJ

  to see an example of programming to use the serial port of 50G, you can reference the following hpcalc GPS data collection program.

  http://www.HPCalc.org/details.php?id=7105

  It is written in userrpl so can be crossed with the reference of users advanced for the translation of the syntax.

  It seems that the main routine of concern for the comm to the gps is in the file "GPS >.

• Tecra A8: external keyboard connected to the serial port: the necessary specific configurations?

  Hello
  I want to share a monitor and an external keyboard with Tecra A8 and a desktop computer. To do this, I bought a switch 2-port Linksys where I plugged the external monitor and a keyboard. With the monitor without problem because there is a specific port for this. However my Tecra has only 3 USB ports and a serial port 6-pin where I connected (with a 6-pin Mini DIN adapter) on the keyboard. When I turn on the screen it's ok, but the keyboard (I also tried a mouse) does not work. Do I need a specific configuration on the serial port to accept the external keyboard? If so, what commands do I need on the XP operating system?
  Thank you
  Luis

  RGB (monitor) port used to connect the external monitor.
  If you want to connect the external keyboard, you have to use the USB ports.
  Additional legacy USB emulation must be enabled for the keyboard.
  These settings you can change in the Toshiba HWSetup under control panel.

  If you connect multiple devices to the switch USB (hub) Please be sure that the USB hub using external power.
  A low power USB could be a reason for the external USB device failure.

• 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.

• Store data from the Serial Port in the buffer and then take action?

  Hello! Everyone,

  I'm new to LabVIEW and I take assistance from various videos and stuffs available online to get started with LabVIEW.

  But I have a duty, therefore needing help.

  initially I see some of the tutorial videos and learned about the LabVIEW interface, and does a little project to communicate with the Port series (receiving and sending data).

  Happens to my task.

  My LabVIEW application will send a few State request packets on my device or control and based on the response packet that I have to display values.

  The Structure of package is as

  Header, length, Op_Code, data Checksum

  There is no terminator as newline or carriage return or anything else.

  In C language, I read the data from the Serial Port, and based on the length, I conclude that I got the full package or not, and then by recalculating the checksum value, the integrity of the package is verified and then based on that Op-Code has been sent will be decided.

  (I'm dealing with hexadecimal data)

  But how can I do this in LabVIEW.
  A tutorial or any referece will be useful for me.

  1. I suggest that you learn to use Shift Registers instead of local and global variables.  They are much more efficient (memory and execution speed) and make it much easier to read the schema.

  2. you don't need this inside the loop property node.  Is there a way to configure a Serial Port to turn off the stop character.

  3. you don't need to wait for playback VISA will limit the rate of loop if no data is coming.

  4. Once you have the length, you simply read the rest of the entire message and process it at a time.  This will make things a LOT faster.

  5. you should really do this enum a def type so that you can ensure that all your enum constants have the same values.  If you need to add a State later, simply update your enum in the same place then.

  

• collection of data & graphical CTS (M-24) using the serial port

  I work to collect data of a test (M-24) CTS station, using the serial number of the station to the serial port on my laptop.

  Looking for information on the vi.

  There is no driver for this instrument (I guess you are referring to this: http://www.cincinnati-test.com/sent_m24.php) on IDNET. Therefore, unless someone has already written an and happen to run across this thread, you will need to write one yourself. It is not hard to do, but you will need programming manual. There are a number of resources to help you write one: http://www.ni.com/devzone/idnet/development.htm. Since you intend to make the serial communication, you should also look over this: http://zone.ni.com/devzone/cda/tut/p/id/4370

• read the serial port PIN +.

  Hello!
  Ive got a question on the serial port. I don't want to make any communication on the port. I want to directly connect an instrument (later), the pin of the connector series #2. On the PIN, I need to read impulses. I am able to read the port pin series, who is active? I know, I can do it on the parallel port. With the port. VI, I give the address of the port, check the D0 PIN for example and the result I can indicate on a led indicator. I want to do the same thing on serial port, because later the target pc will be ve no parallel port. Is this possible? Can you give a statement of departure?
  Thank you very much for your help!
  Mr. Gabor

  You can read the down state from some other lines, DTR, RTS, etc.. There is an example that comes with LabVIEW. Open example Finder (help-> find examples) and search for "Troubleshooting Serial Line Monitor" example (just search "series").

  This can be considered an e/s digital interface a poor man, depending on what you are doing, you can be better with a 'real' digital i/o interface.

• Transfer an image via the serial port of PC to PC

  Hello world

  can someone help me to transfer an image file to another PC with Labview via serial port?

  is there an easy way to just sent and receive an image via the serial port file?

  Thanking you in advance.

  Hello

  I love people who love to learn. Thanks for listening.

  I updated read and write Subvi is because I believe keeping simple and straight threads more readable program and less bugs remain.

  Even better, my eyes straight lines i do not get tired too soon.

  good luck with your program.

• 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.

• 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.
