• Serial communication error VISA with LUDL stage controller

  Hello

  I'm trying to control a micro-positionnement made by Ludl stage. The model is Ludl MAC2000. It seems that the RS232 comunnication is implemented because I can talk to the controller using HyperTerminal. However, when I want to do the same thing through Labview, I can't answer the controller at all. The vi is roughly the same as the visa basic read/write in the example. Looks like a very similar problem in this post:

  http://forums.NI.com/T5/instrument-control-GPIB-serial/visa-serial-communication-problem/m-p/567065#...

  But the trick of nature of endpoint does not help in my case: I tried to toggle the termination character setting in the property node and different combinations of '\r', '\n' as termination characters, but nothing has worked so far.

  Seems to me there is some difference between the interpretations of the same order to Hyper Terminal in Labview. But I just can't understand what it could be.

  Anyone with a similar experience could give me some comments/suggestions? Thank you very much!

  Another difference between hyperterminal and labview is the speed of sending characters.

  LabVIEW breaks out the whole string to the controller

  HyperTerminal is this character by character. So much slower and slow the controller can be affected by this.

  You could add a loop around the writing of visa (to make it easy convert the string into a byte array outside of the loop and convert it to a string inside and you have a shipment char by char in LabVIEW

• Communication of VISA with connected USB GSM modem using a protocol AT

  Hello, I am writing an application that should send sms messages.i have a connected USB GSM modem that supports the PROTOCOL. The modem works by using its own software and the HyperTerminal.I have used VISA driver development Wizard to create the .inf file. The device is now recognized and registered to the MAX. However, I can't understand how to code the commands and read the responses using write VISA and VISA read. Thanks for the help, Dima

  The last thing you should have to do is create an INF with the wizard. Remove completely and the compiled version. What you want to do is to use the inf file supplied with the device which a serial port to the BONE and makes it usable with Hyperterminal. It should appear in MAX as a serial port. Once you have restored all the way it is, then you can start with the examples of series and writing to it should work as it did in Hyperterminal. In other words, simply send the chain of command.

• With the help of dynamically called screw in TestStand deployment

  I write code to interface with a & Rohde Schwarz ZNB Network Analyzer.  I use LabVIEW 8.2 and TestStand 3.5.  For reference the ZNB driver is available here: R & S of ZNB Driver.  I use a slightly older version of the driver, some before they needed to LabVIEW 2009.  I am writing all the code on a development machine that has the full version of TestStand/LabVIEW and it works on another machine that has the TestStand deployment license.

  This driver is dynamically linked to some things he needs.  I am able to operate with simple LabVIEW EXEs but not in TestStand deployments.  The following excerpt comes from their documentation, explaining a little about how the driver works and how to use in LabVIEW EXEs.

  3.4.2 How to generate executables or libraries in LabVIEW driver kernel drivers instrument based on attributes is dynamically bound to any VI performed during execution. This can be recognized by the LabVIEW application builder. The LabVIEW application builder follows all the static dependencies and include them in the package distributed at the generation of an executable file.

  To create an executable in LabVIEW, please manually add all the screws in the \PREFIX \_utility\callbacks folder to the LabVIEW project. In the case of project based please add private to your project folder. With this reference manual, the driver core is included in the compilation and the driver core is accessible during execution.

  I can't get this to work in TestStand deployments at all.  I can't even connect to the device since the VI Init has these issues.  I get the same error for all the various attempts that I made.  The same error is that when you add manually the screws for the LabVIEW EXE.

  So far, I tried the following, all solutions producing this same error.  I struggled with this and turned off for awhile then maybe there are other solutions attempts I forget.

  (1) it looked like a lot of the report to go to the private folder were finished in SupportVIs.  I manually pasted the rest there, too.

  (2) I added all driver files on my workspace and included in the files with the rest of my deployed screws.

  (3) I added all driver files on my workspace and said pilot TestStand to deploy them to the original location in Program Files.

  Someone at - it ideas?  R & S didn't even know what was TestStand, so that they could not help me.

  I was finally able to solve this problem on mine, the other day.  I brought the Network Analyzer to my office and did a lot of tests in this way.  Eventually, I discovered that I needed to include the folder private pilot deployment, what I was doing in one of previous attempts.  It turns out that you must also maintain the original of this file directory structure when you include it, otherwise dynamic calls are not looking in the right place.  Once it worked on my PC, I got it on the machine test and worked as well.

• Can someone help me on action with agilent 34970-34901 has continious

  I need assistance with 34970-34910 has continious measurements. Everyone says that you need to configure "Agilent 34970 has advanced Scan.vi". I have modified this vi to measure temperature and pressure (current) but I could not go a sterp before measuring very. How can I do this? I have attached the vi that I modified.

  I solved the issue of measuring continuous with Agilent 34970-34901 has. All my error is in the configuration of the usb serial port. To the continuous measurement, the flow of control of the usb serial port configuration must be implemented as 'XON/OFF' and the same setting should be made in the vi. You could measure temperature/voltage/current at the same time by doing this.

• "communication not available with the printer" message when you try to print to a Lexmark 1270 x all-in-one

  I am running windows xp family.  I don't know what happened, but all of a sudden, I get this message when I try and print to my lexmark x 1270 "communication not available with the printer. I tried every troubleshooter, I contacted Lexmark support that they gave up, saying: it must be a file is missing from the windows registry, you can help me?

  It seems that if you say that the pilots were not reinstalled successfully.  What was the mystery file that could not be found?

  Do you remember how the software has been uninstalled?  Was something else than the control panel > Add / Remove Programs (or the link "Uninstall" from start > all programs) used?

  If you do not really clean things, attempts to reinstall the printer drivers may actually just end up putting the old drivers back in place.

  This is the easiest way to uninstall and reinstall the printer drivers: Article 1.  The critical step is #4.

  This page has more detailed advice for cleaning things out before you reinstall: http://members.shaw.ca/bsanders/CleanPrinterDrivers.htm

  I asked the firewall and antivirus applications because sometimes, some security software may interfere with the printers.  This shouldn't be a problem with the firewall of Windows XP and Microsoft Security Essentials.

  Finally, your problem could end up being hardware related.  Lexmark support has no hardware troubleshooting operation?  The manual for your x 1270 says:

  All-in-One is not communicating with the computer

  1. disconnect and reconnect both ends of the USB cable. For more help, see the
  installation documentation.
  2 unplug the power cord from the wall outlet, plug it in again, and
  Press Power. For more information, refer to the installation documentation.
  3 restart the computer. If the problem continues, remove and then reinstall
  the software. For more information, see page 16. [which ask you to remove the software using the link "Uninstall" - which is not complete, as described above]

  If you have another type of printer USB cable, you should try it exchanges.  Ideally, you need to connect to the printer on another computer, but maybe it's not convenient for you.

  This is an old issue, but for someone who comes here looking for answers:

• With the help of modulated signal pulse width (square wave) to control when a signal is enabled or disable

  With the help of modulated signal pulse width (square wave) to control when a signal is enabled or disable

  Hello all

  I am using a modulated signal to labview created pulse width (square wave) to control when a signal is activated or not.

  Here is my logic and a concrete example:
  (1) the wave source signal is continuous
  (2) use a PWM (square wave) created in labview to control when the signal is enabled or disabled
  (3) if the PWM (amplitude) signal is superior to 0 play signal PWM is not greater than 0 do not play signal.

  I use actually this to the sequence step / pulse several distinct magnetic coils using my audio card (which has several channels of audio output), I have a signal in labview played constantly.  As to compare it to the PWM (square wave) which controls whether or not the signal is played on each separate channel.  That way I can control which coil is on and offshore and in what order they are activated.

  I couldn't find an edge detection for a square wave created in labview, so I tried the limits, but it doesn't seem to work unless I change the phase manually and it only goes 1-1.  I'm just trying to compare the PWM (edges of the square wave) already created by labview / play a signal if the pulse is greater than 0 and it shuts off the signal, if she is less than 0.

  Should I do this another way

  TIA

  A waveform contains an array of values. You must check every value and respond accordingly:

• Communication Serial Port with PIC

  Dear all.

  I am interfacing the labVIEW to an eeprom controller PIC, where I need to input data user to store in a location memory EEPROM, according to my condition that I've done programming the pic and it works very well with hyperterminal, at the same time I need to do with a labVIEW using communication serial port VISA , but when I did I receive a warning in 1073676294 that cannot be ignored, but I am not able to write user data to EEPROM by labview but I can do it to hyperterminal, please someone help me on this.

  Charron a G

  I was interfacing to pictures for a while, and the example that you have to build from was the same that I used. First, move the initialization OF THE outside of the loop. No need to re-initialization of the COMM PORT every 750ms.  Inside the code example, there is an expectation of 500ms between WRITING and READING (it is hardcoded for now, you brought it out on the ICON).  So time total is 750ms loop over the 500ms wait (more traffic comms), FYI.

  You do not use a return of ramasseherbe (13) or a NEWLINE (10) as a dismissal. You use a SO (14). Unless you're on a triggering a 14 ASCII in the PIC, the PIC will never see the "end of the chain of command" to analyze out. I have attached a good routine of init (IMO) I re - use on all my PIC projects, take a look.

  I use compilers Mikroelectronica MikroCPRO and displayed a complete interface of the UART (triggers on a CR (13)) on their site LIBSTOCK if you want to take a look at the side of the PHOTO of my work.

• Communication problem series with USB serial Hub

  Hi, I have a communications problem when I use an NI USB - 232 (778472 - 01) adapter to control a pressure sensor. There are a lot of posts about it in the forum, but I calmly something a little different. I can't use MAX to control the instrument with the VISA test Panel. So I guess that the USB-232 driver is correctly installed. However, in labivew, even if I choose the instrument source of visa name, it always returns an error (-1073807339) when I run the program. The screenshot of the labview program is attached. Could someone kindly help me with this problem. Thank you very much.

  The system is XP SP 3 Pro.

  The version of Labview is 8.6.

  The MAX version is 4.5.0f0.

  If port by default windows settings exactly match the settings you need for communication, you can get lucky and it will work.  If only one parameter is different, it won't work.

  It is always better to define the parameters in your code.

  Shane.
