USB serial Converter

Hello, I need to connect my PC to a device with a serial port (rs232). However, I don't have an available serial port on my CPU, so I was thinking about using a USB converter to series. However, I've never used before. My question is if these converters are ALWAYS two-way or some don't work only one way. If so, is it so unidirectional or bidirectional converters, can they communicate from the PC to the device? Here's the thing, when I went to the store to get one, I was told that it communicates only from the device to the PC and I need it the other way around. Since this is the kind of emergency, I intend to use a converter that is NOT of National Instruments. However, the control software for the device is a VI.

Also, if I can use the converter to communicate data from the PC to the device, LabView detects the port as a normal serial port or what I need to do my VI to control the usb port?

Thank you

Ali

Thanks to all for your responses. I also thought buy a PCI with two ports for PC series, because I think they are a little more reliable. Anyway, I tried the converter and so far it has worked well. Thanks again.

  • Need Vista driver for a USB-SERIAL converter

    I tried to plug in the USB-TO-Serial but it seems that there is a problem with the driver I bought the USB-TO-Serial converter without Vista driver.

    Could you please tell me to do?

    It could be a good idea to find the drivers right to the website of the manufacturer of the USB-To-Serial adapter for Vista drivers.
    Otherwise I think there's not much you can do right now.

  • Name of resource VISA get does not have USB serial ports

    We built an application on a computer that had a built-in serial port - COM1.  We have the option to change the COM port in the application.  We have installed the application built on a computer that has no serial port, but installed a USB serial Converter which records as COM3.  LabView does not see this port, even with a test application to return only the names of VISA resources.

    We have verified that the port is good with another program (a Modbus Simulator) and installed the last TIME VISA v4.41 separately without result.

    Any suggestions for more troubleshooting would be extremely useful.

    Joe T.

    My main of the application still does not work, but now the little test ones are.

    Here's what I did:

    1. update my LabView 8.5 with the last VISA - 4.4 runtime.  This update the installer as well.

    2. added the install MAX for the build.

    3. adding the Support of Configuration of NI-VISA for construction

    4. uninstalled the app and reinstalled with the new volume of the system.

    When I run MAX, COM3 appears.  He also appears in the application of test resources.  The simple test Modbus to write the program works, too.  I have a sneaky feeling that COM1 can be hardcoded somewhere in the parent application; our next task is to find where communication breaks down in our code.  The bottom line seems to be a lack of experience with the demand of our manufacturer.

    Thanks to all who participated!

  • Satellite L30 - required USB serial controller driver

    Hello everyone,

    I can't find the driver for USB-serial controller C for my Satellite L30.
    Needs in order to connect my Samsung mobile.

    Thanks in advance,

    Jacob

    To be honest I had never heard about USB-Serial Controller C.

    The windows operating system contains drivers own controllers USB (USB port).
    This means that you will not find any special drivers for USB controller.

    If you have some connection with the cellphone problems then I recommend to install the software that was supplied with the mobile phone. There is always a CD with the software.
    Before installing this software, you must uninstall the previous software.

    By the way; You can delete the C USB-serial controller in Device Manager and reboot the laptop. Then check if the windows will recognize this controller again.

  • With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable.

    With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable, since I do not have rs232 ports. I have two instruments I want for the control in this way. One is a guarantee of strength Imada SPAS with RS232 output. The other is a micrometer Panasonic HL-G103-S-J laser sensor which is RS422. I have done significant programming LabVIEW using GPIB, but I have no experience with devices such as these. No matter what tutorial or examples would be greatly appreciated.

    Thank you.

    When you plug the USB-RS-232 converter, it installs a driver under Windows which makes it look like any other RS-232 port.  You may need to install the driver of everything that came on the CD with the converter.  It will get a Com as Com5 port number according to what is the next available number.

  • I need to control and communicate with a cell - Mecmesin Multitest 2.5 k - via USB/serial - ideas?

    Help!

    I am currently working on a project where I apply force on a hardware - software (non-associated labview) who is provided with the tool (Mecmesin Multitest 2.5 k) allows to control but (of course), I want to control it using LabView, as well as plot data using LabView.

    This issue has developed several years on these forums, but it was never a good answer. I'm suitable for use of LabView for the simplicity of programming (loops, arrays, sorting data etc.), but am a newb in most other respects--unless companies have subVIs!

    The tool is now using a USB-serial connection (PC - end is USB). I think I could use rs232-rs232, but someone in the dept said it still doesn't work, which could mean that the cable series is cheesy. I wish it works however, USB, as ideally something else is connected to the serial port currently.

    Is this possible? If Yes, can anyone help?

    The next step is to open the manual for programming the instrument. Determine the commands that you need to send to the device and to understand how the device sends information. You can use the signs VISA for that test or program such as Hyperterminal. To send something to the instrument, you use an entry VISA (tab ViWrite) and for the data, a VISA read (ViRead).

  • Tracer USB Serial Driver for USB 2.0 need to connect... Help!

    My old computer died and now my vinyl cutter does not connect to my new. I said needs 2.0 USB Serial Driver which he cannot find. Help!

    It sounds as if you have an old vinyl plotter of a series and (b) interface has at one point bought a USB to serial adapter or cable.

    If the above is not correct, what is the brand and model of your plotter?

    If you can't find the CD that came with your card and cannot identify it (so you can search for a driver on the Internet), your simplest solution is to buy a new USB cable or serial adapter that comes with its own driver.  They seem to run from $ 10 to $ 20 or more.

    Do yourself a favor and read the comments in places like Newegg, TigerDirect and Amazon before deciding that one to buy.

    Another alternative (that some of the negative reviews on the cables/adapters mentioned) is to buy a serial port PCI card (assuming that you have a free desktop/tower with a PCI slot computer).

  • A problem with Aten UC232A serial converter in windows 8

    I have still the problem mentioned earlier (on your site) with Aten UC232A serial converter in windows 8 update. The installation of Aten software stopped, because the installation program does not accept windows 8!

    My problem is solved through the provider Aten. The provider send me a new set of driver (PL2303Driver_ATEN_v3430230_INF) for the converter. So I manually install the converter and it works.

    Thankfully, I am messy my new equipment this morning.

    It is a software problem (driver).

  • Java USB serial port connections

    I was not able to open a serial port usb using "comm: / dev/ttyUSB0 '. BaudRate = 9600' connection uri. Pouvez USB serial ports available through java?

    Hello!

    What version of Java are you using ("Ai2" or "ai2 last developer version ')? In the latter case, you would not be able to open the serial port using Connector.open.

    In case if it is just ai2 it should be possible. An adjustment to the installation, you should do, however. In the file jwc_properties.ini please change the property deviceaccess.uart.prefix of/dev/ttyAMA/dev/ttyUSB (Please note that there is no '0')
