WIth LabVIEW how do I control an instrument with a RS232 output, using a RS232 to USB converter cable.

WIth LabVIEW how do I control an instrument with a RS232 output, using a RS232 to USB converter cable since I dont have rs232 ports. I have two instruments that I want to control in this manner. One is an Imada ZPS force gage with RS232 output. The other is a Panasonic HL-G103-S-J laser micrometer sensor which is RS422. I've done considerable LabVIEW programming using GPIB but I have no experience with devices like these. Any tutorial or examples would be greatly appreciated.
Thanks.
Solved!
Go to Solution.

I understand that you want to control a device which having RS 232 port as output. If so, you can use an USB-RS232 cable from PC to device and you can control or monitor the device.
See this link http://zone.ni.com/devzone/cda/epd/p/id/2669
Also, first check the device in hyperterminal and then continue to program in labVIEW. You can find the serial VI's in Instrument I/O.

    "hi....
    I've ever controlled some instrument by GPIB interface using Labview 6.0...it's really easy to implement .....but the problem is that i hvae to control those instrument under the pure DOS environment now ..so i have to abandon the using of GPIB interface and Labview ....then i choose the RS232 interface with programing the Borland C++ v3.1 and sending the SCPI command by bioscom()....but it got no response at all......so i am wonder if i can control those instrument by using RS232 interface and Borland C++ v3.1 to implement a pure Dos program????if yse,how can i do and is there any sample can be refer to ????
    thank you for you help"

  • In Logic Pro 9, how many midi controlled software instruments do you get...?

    In Logic Pro 9, how many midi controlled software instruments do you get and is there possibility to download more as it says 40 on the programs info on the Mac Store, as i intend to compose on it but with only 40 instruments it's not really worth it.
    So i was just wondering whether it let you download more for free.
    Thanks for reading
    ~Matt

    Yes: I too am interested in the software instruments available in Logic Pro: one has to be a bit wary of the jam packs because there don't seem to be many solo instruments included. But I looked at the Logic screen in an Apple store the other day, and it worked like GarageBand in
    this respect: you created a new track choosing the software instrument option and a whole lot of instruments came
    up in a column on the right: lots of solo wind instruments, plenty of keyboards and guitars of course and not very many solo strings, only one violin, in the world music subsection under Irish fiddle. Yehudi Menuhin
    where are you when we need you?
    What I've been trying to find out is which part of the purchase does this long list of software instruments arrive with, because it's basically the only reason
    I'm interested - I get on fine with gb but it
    Just hasn't got enough instruments, and as I say the jam packs don't seem
    to resolve this ? Or do they? Could someone please help
    me with this?

  • How can i control background colors with items (registry.dat)

    Hello Evry one.....

    The iPhone has a "remote" app that lets you control Keynote on a Mac, but not on another iOS device (iPhone/iPad/iPod Touch).
    There are some apps that let you control limited content on another iOS device - but the content has to be within the app. You might check out SyncPad - perhaps you can import the presentation into it and then control it on the iPad.

  • HP Laserjet 6MP fails to print with parallel-to-USB converter cable

    I have a LaserJet 6 MP parallel printer which I was using in 10.3.9 with a parallel-to-USB converter cable. The Printer Utility saw it natively as a USB device and it printed just fine most of the time, although it would occasionally fail to print, so I installed a different driver called usbtb 1.0.15, and after that it printed very reliably.
    Now I've upgraded to 10.4.9, and the Printer Utility still detects the HP printer natively as a USB device, and I also installed the formerly-reliable usbtb driver again, but the printer now fails to print with either driver. It acts like it's going to, but then it quits.
    When I choose Print, all the features of the printer are shown, and I can select which tray to take paper from etc., and the printer dialogue box says "Printing," the activity light on the printer flashes just as it always does when printing is in progress, but then, instead of printing, the activity light stops flashing and the print job disappears from the dialogue box.
    Can anyone tell my why this printer is failing to print now, and how I might be able to get it working again?
    Thanks,
    Tom

    Wait a minute! It's only certain Indesign documents that won't print.
    All TextEdit docs will print.
    I created a few scribbles in Photoshop and they print.
    But with InDesign, there is no predicting which documents will print or will not print. On some that will not print, if I remove all but one text box, then they will print. On other documents that do print, if I copy some text off of one that won't print and paste it in, then that one stops printing too.
    On some that won't print, if I erase everything on the page and create a new text box and type a few words into it, the page will print. If I revert to the previously saved version, once again the page won't print.
    What kind of craziness is this, anyway? It seems random. I can't figure it out.
    Even on the documents that won't print, when I try to print them the printer's activity light blinks as though it is just about to print, but then the light goes out without printing.
    Anybody got any ideas what this problem is and how to fix it?
    All I know is that EVERYTHING printed before I upgraded from 10.3.9 to 10.4.9.

  • How would I interface an instrument with a serial UART output to LabVIEW?

    I am trying to gather some information on a upcoming project. I have a instrument that outputs a serial UART stream. I would like to interface this with LabView. This is the product that I am planning to interface with. http://www.pressureprofile.com/products-digitacts.php I am just learning how to use LabView so this is all new to me, any help would be greatly appreciated.

    First- I would recommend takinga look into the Basic serial read and write example that ships with LabVIEW.  Second, RTFM (Read The Friendly Manual) for the device.  A Google search for serial comms will provide a reasonable backround for how serial comms can be configured. 
    As to how to implement the specific serial protocol in LabVIEW-- well, use a VISA call to the serial port to configure the various properties of the VISA ser:instr class and IF you learn the equipment's expected settings and what, and when, it responds, the "nuts-and-bolts" of wiring your device driver becomes reasonably simple.

  • How can I control PIC programmer with LabVIEW

    I need to control a PIC Programmer (MPLAB PM3) with LabVIEW. How to do this?

    Hi Paul.
    I am working on a project that is using LabVIEW to communicate via serial communication with 4 programmers (Com 1, 2, 3, & 4). I am currently using the Microchip PM3 programmer DOS utility PM3CMD.exe to send/receive commands from the system exec.vi in LabVIEW. I am attempting to program simultaneously with 4 programmers, but the PM3 programmers are returning a database error if I try and communicate with more-than 2 programmers at a time. I noticed that you have some experience with some drivers from Microchip and using serial commands.
    Do you have any suggestions that may help me.
    Thanks.

  • How to remotely control an instrument​?

    Hello,
    I have an instrument(TDS Oscillscop) hich is connected to a host computer through GPIB, so how can I do to control this instrument at home? thanks,
    Mike

    You could configure the host computer to use VISA Server, then access the instrument as if it was connected to your computer at home.
    The concept is simple, but things like firewalls, routers and port number filtering often get in the way when trying to do this sort of thing over the internet.

  • When opening a Photoshop file with Bridge, how can I control which version of Photoshop the file wil

    When opening a Photoshop file fthrough Bridge, how can I control which version of Photoshop the file will open in?
    I store my PSD files adjacent to the original RAW file from which it was derived.
    If I open the file folder and double click on that PSD file, it opens in CS6. But,if I use Bridge (CS6) to navigate to and open the same file, it first opens Photoshop CS5 and then opens that PSD file in CS5.
    How can I control which Photoshop will open a file I select when opening it through Bridge?.

    Interesting, but it doesn't give a clue what I'm supposed to do. No Photoshop ducuments listed.
    Look at the PSD file on the location Curt provided and search for Photoshop Document. Next to it ideally should show Adobe Photoshop CS6 if you have Bridge CS6 open. Click on it to provide the fly out menu and choose the correct Photoshop from the list.
    But probably something went wrong with your install. By default Bridge chooses the latest version of PS to open its file in.
    Maybe a reset of the preferences might also help you. Can you provide more details about OS version etc.
    And do you have a good reason for keeping your Raw and finished files in the same location. Personally I keep them apart and use a proper file name convention (yyyymmdd and details) so I can easily search for the DNG files in my archive if I needed them but I don't make mistakes in opening the wrong one

  • How do I control itunes volume with my Apple Remote?

    Hey,
    I have been using the Apple remote for a while now, but recently i have got a airplay device, for which the volume from the mac can be controlled only by the itunes volume slider and not the mac volume.
    can someone please guide as to how i can change the itunes volume with the remote?

    I don't know how to do it with the actual silver Apple Remote. However with the Remote app on you phone then the volume control is at the bottom just like normal. When you use the Airplay symbol to send the content to the airplay device say Apple TV you can use the volume slider to control the volume.

  • How can i control a slider with a button.

    Is it possible to control a slider with a button? It works like a automatic sliding gate. Is it possible? Where when you open the gate, it will slide slowly.. And can anyone help me with this..

    The way this usually works is that I think of a simpler implementation once I click the Submit button...

  • How can I control the window size of my output?

    Hi,
    I'm drawing a blank... How do I control the size of the window that my project is viewed in? Right now, it's the entire browser window.
    Thanks,
    Janice

    Hi,
    From your post, I assume you are creating WebHelp output.
    You  need to create a window for the help in the Project Set-up pod. Then,  you need to make sure you call the output so that the window is used.  See http://www.grainge.org/pages/authoring/calling_webhelp/calling_webhelp.htm.  This article on Peter's site give you an overview over the  possibilities of calling context sensitivive webhelp and also tells you  how to specify the needed window. Also, the installation directory of  RoboHelp 8 contains a directory called CSH API. In there are example  API's your developer can use to call the help.

  • How can I control the order of iDVD menu items using the Arrow keys?

    I have a submenu screen containing 10 selectable buttons plus the Return Arrow button.  I have ordered all the slideshows in the correct order in the DVD map.  However, when I run the program, the arrow keys jump the selection focus in an apparently random sequence.  How can I control the order of the selection focus?
    I'm using iDVD v 7.1.2
    TIA.
    Ron

    Hi
    There is one thing You might miss in iDVD - So do I - the ability to re-arrange in the DVD map (block diagram)
    The order things will be pplayed or addrssed is same as the order each item is introduced into iDVD.
    To my knowledge ther is no way around this.

  • How to create control dynamicall​y while front panel fly using Xcontrol or anyothere options but without scripting tools

    Hello friends
               I have one doubt How to create control dynamically while front panel fly using Xcontrol or anyothere options but without scripting tools.I need to create the controls while vi is running.For example I need to create one Boolean  while VI was Fly and i need one Examples it is easy to understand.
    Jayavel

    You must be using a different dictionary than the rest of us.
    You can't dynamically create controls while a VI is running.   (If I'm mistaken, then I'm sure someone else can jump in and say how it can be done.)
    Do you have a finite number of controls you could possibly need?  What you can do is create enough controls of the type you need ahead of time.  At the beginning of your program, you hide all of those controls.  As you need to create a control, you make it visible using property nodes.  There are numerous properties you can set at run time suce as ranges, colors, captions, ...  Of course you can't wire these controls to any other bits of code ahead of time since at that time, you haven't defined what you want each one to actually control.  But if you use an event structure to detect when the values of the controls have changed, you can then programmatically pass the data off to other parts of your code using queues.  The architecture can get complicate quite fast, so you may want to look through Ben's Action Engine Nugget and other related threads for how to create mechanisms for using these controls.  Perhaps storing queue reference numbers or assign user events to each one.
