Serial devices RS232, OCX or PLL

I am looking for a FORMS pll or ocx to talk to serial devices (RS232). Is there an interface for Oracle to download?

You should be able to use almost any terminal emulation application, e.g. the shareware program ZTerm or the communications section of one of the ClarisWorks versions, to receive data/files directly in a Mac OS 8.6 environment.
In order to view image files, something like the shareware utility GraphicConverter may be of interest to you.

  • Serial Device Server

    We have a four port RS232/422/485 to Ethernet serial device server with a static IP assigned. How do I read / write to (using MODBUS IP) the individual ports? Building 4 seperate MODBUS objects using the same IP address, but differant identifiyers (1-4) be the answer? The other answer is to use virtual comm ports, but would rather do this without that if possable.
    Thanks all

    You can use TCP only if the device supports RTU to TCP conversion, such as many IAP gateways.
    Otherwise, its Virtual COM ports.  Lookout hates them, especially if the link is high latency.

  • I am trying to reset a serial device through serial port ,MAX is able to do it but the same command is not working in labview

    max can do it but labview cant

    - Run NI Spy Tutorial
    - Reset the serial device in MAX
    - Run the LabVIEW code
    - Post the *.spy file.
    The spy capture will show any difference in function calls to the driver.

  • Do I need a NI serial device?

    I am working on an application which involves reading pressure data from two pressure gauges (differential and vacuum).
    My PC has two free serial ports. My questions:
    1) Can I use the PC serial ports or is it advisable to opt for a NI 2-port serial device? Reason?
    2) If you suggest that I go ahead with existing PC serial ports, then, can I still use the power of LabVIEW and VISA to read and display data from these ports?
    I have LabVIEW 6.1 professional.
    Thanks!

    Thanks Chris. That helped!
    Find below replies to your inputs. Feel free to provide any further inputs and suggestions.
    - All devices are RS-232
    - No. All devices are slower than 115.2K
    - No, we do not need deep FIFOs. The application is simple and involves acquiring data from two pressure gauges at slow intervals of say once every 5 minutes.
    - I am not sure. What do you advise?
    Do you think I need to invest in NI hardware?
    Can I save money by using built-in COM ports and still leverage the power of NI LabVIEW?

  • Connection with serial device (SPP)

    I try to connect with a bluetooth serial device (a robot, no standard device) which is working with every PC but not from my MAC. I can connect to the device (I use ZTerm) and send one character, but not more. If I send more, those characters are not send until I quit and restart ZTerm. Then (nearly) all characters are sent. I can get all characters sent by the device. It seems a problem of flushing the buffers at some level of the drivers. Any experience or idea?

    Hi!, Ranothil: If you have the next cable and "null modem" (http://commerce.hpcalc.org/serialcable.php), you can transfer, anydata, from HP50G, to PC and viceversa, across Connectivity Kit (Conn4x), without problem. Please, see this link, with instruction's, for transfer data with serial cable, null modem and connectivity kit ... http://sense.net/~egan/skb/ and/or ... http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv017.cgi?read=125259 Note: Better, if you transfer data, from HP50G to, PC and viceversa, across the microUSB.  

  • Best architecture for testing multiple (8) serial devices

    I am not new to LabVIEW but am being tasked with a challenging project I want to be prepared for as best I can.  I am familiar with Event Structures and State Diagrams but feel these may not be adequate for the following specifications:
    1.  Most likely 8 serial devices need tested simultaneously
    2.  Tested every 2 hours for 48 hours
    3.  Records for each one must be created and saved at each interval
    I want to learn Queue's etc and am thinking a combination of producer consumer and the above two mentioned may be required.
    Any basic architecture recommendations that may work would be appreciated.  FYI, I have never used Producer Consumer.
    Thanks

    As tbob pointed out, the architecture will be fully dependent on the exact details of the problem.  That being said, I do have my two cents to put in.  In my work, I deal a lot with serial communication (too much, in my opinion); in some instances, I am dealing with the same device on different machines and in other instances, different devices talking on different ports on the same machine.  Regardless of what the implementation is, you will find that there is a lot of commonality to be found in serial IO (open port, close port, configure port, send ascii command, receive ascii data, block simultaneous attempts to R/W, etc, etc) that is really independent of implementation.  To me, this just screams for an object-oriented approach.  The ability to reuse or change the details of the code while limiting changes to the interface itself is awesome.  In your case, if you have 8 similar devices, I see 8 instances of a class which inherits properties from a Serial IO superclass; if we are dealing with different types, then you can exploit the inheritance features of objects to basically call 8 instances of different children of the Serial IO superclass. 
    All that being said, I think some of the details are missing as tbob pointed out.  However, instantiation of 8 objects will prevent some of the issues that might be associated with asynchronicity as all of the properties and methods would be associated with an instance. 
    Anyway, that's my thought.  Give me another week or two and I will probably have an example of this up.

  • Control a generator with a control volage by serial port RS232

    Hello everybody,
    I would like to control a generator thanks to a control voltage. This last one would be sent to a switch wich turns on the generator.
    To do that, I want to link the switch and the computer with a serial port RS232 by using NI-USN 232 cable.
    I made some research on this subject and I am only a beginner on LabView but I would like to use one (or several) pin which will send 5V in voltage when I want.
    Is that possible? Is there another way to make it?
    Thanks in advance.

    Thank you for your answer.
    Maybe, I didn't explain myself correctly. 
    For example, on the Raspberry Pi, you can control a card by sending 3,3V signal with RS232 port (I made it last year so it makes a sense).
    What I want to do here is to control an electronic card that turns on my generator after. I don't have enough to buy a generator controlled unless you know one not very expensive.

  • How to generate non-blocking commands to a serial device

    I have a serial device which accepts non-blocking commands. This is, if you send a command that takes 1 minute, while this happens, you can send more commands and they will be executed. Once a command is done, it sends back a code that relates to that command, so you know it is finished.
    I have a VI which tries to communicate with this serial device (see attachment). It does work, but it blocks the execution until a command is finished. So I can send commands one by one, but not in parallel, or in a delayed non-block way. The problem is the while loop which waits until the device outputs something.
    I need to do something similar, but non blocking. The VI should be able to send several commands while others are executed.
    This subVI is controlled from a main VI, which is just a State Machine with a few states, where each state is some action which is sent to this subVI, and then to the serial device.

    Use another loop that does nothing but read from the serial port.  Report the data to whoever needs it with a Queue.

  • USB Serial Devices - Descriptio​n and Informatio​n

    Hello folks, I am trying to detect which kind of USB/Serial device is connected through Labview: through the VISA Find Resources i can list all the GPIB/ASRL devices connected and then through the Interfice Type i can detect the Serial/USB devices (interface number 4) and through the Interface Description I can get the name (COM7 for example).
    Now my point is that if i look on the "Device Manager" in Windows i can see the "Manufacturer Name" and the "Device Description from BUS" of the Serial Device connected. Is there a way to get those information inside Labview?
    Thanks in advance and best regards

    the best option might be to use DevCon, a commandline based device manager from Microsoft.

  • Send thru serial port (RS232) the instruction CTRL+"something"

    How to i send thru a serial port (RS232) the instruction "CTRL", like CTRL+"something", im only looking for the special character CTRL, i have seen that it can send a CTRL+A ... CTRL+Z thru a type cast, but  is not what im looking for, im sending a special instruction (CTRL+PQT<package>) thats requires this character.
    reards

    The control key is not something you can send through a serial connection.  It is a modifier key (like Shift and Alt) and not a character that would have an ASCII value associated with it.
    However, many of the special ASCII control characters (those below decimal 32) can often be entered as a CTRL+key combination.  For instance, the beep is ASCII 8 and is also a CTRL-G combination.  The backspace is ASCII 9 and CTRL-H.  CTRL A is ASCII 1 so sending a string set in hex display as 01 or \01 in \codes display would work.
    What is (CTRL+PQT<package> supposed to mean?  Is it Ctrl P followed by Q T then something else?  What equipment are you trying to interface with?

  • Module 9870 for reading 4 serial devices...

    Hello,
    I want to use the 9870 Module with the cRIO 9022 to be able to read 4 diferent serial devices. Is this possible? If so, do you have a VI that can handle the 4 devices??  The example you have can handle only one port.
    Thanks,
    Hector.

    Hello Hector,
    I am sorry I pointed you to an example that wouldn't help you.  To configure the serial ports you can just drop an FPGA I/O point on the block diagram.  Each I/O point has a variety of properties to it as shown in the picture below.  You can place multiple loops down to talk and listen to each port on your 9870 independently.

  • Interfacing of RS232 serial devices through USB ports within LabVIEW 6.1 and Windows 2000 Pro?

    I have a data acqusition requirement of using 5 RS232 devices, but the motherboard i use only has two serial ports. However, it does have 4 USB ports. Does anyone know if it is possible to use these USB ports to input data from an RS232 device through a serial to USB converter?
    Does LabVIEW 6.1 support this under Windows 2000 Pro?
    Thanks in advance,
    Fraser

    Hi Fraser,
    I just moved an app to a new laptop and had to use a USB to serial comm adapter. At first try the app did not find the comm port.
    After sleeping on it, we downlaoded the most up-to-date driver for the device and upgraded VISA to the latest and gretest version.
    Everything worked fine after that.

  • Cannot upload data to serial device using x-on, x-off in Labview but works OK in Hyperterminal

    Hello,
    I'm trying to write a Labview 7.1 App that will upload a motorola .S28 file to a custom designed piece of hardware. The serial port on the hardware device requires the serial port settings be set to 9600, 8,N,1, none, for general operation and my Labview app is able to send and receive information from the hardware using the NI VISA 4.00 serial read and write routines, so I know that there are no fundamental communications errors.  The general communications also work when I set the com port to 9600, 8,N,1, x-on, x-off.
    The problem I'm experiencing is that I can upload calibration files (which require x-on, x-off flow control) in Hyperterminal by:
    1. configuring the Hyperterminal session for 9600, 8,N,1, x-on, x-off
    2. selecting "Transfer--> Send Text File... when my device prompts me to upload the file.
    This works 100% of the time in Hyperterminal, but I cannot accomplish the same upload in my Labview app.
    The very first thing my LV app does is to pop up a dialog box to the user prompting him/her to select the desired com port (Visa Resource Name), Baud rate, Data bits, Parity, Stop bits, Flow Control, and allows the user to enable/disable the termination char and to set the termination char (always enabled and set to default 0xA).  The flow control is set to x-on, x-off. This is accomplished using the VISA Configure Serial Port vi. 
    I have tried using both the VISA Write From File vi and also reading the file to a text variable then using the VISA (serial) Write vi but neither work. The VISA Write From File vi  return count correctly identifies the number of bytes in the file but the hardware never returns it's transfer complete status message (remember this works 100% of the time in Hyperterminal).  Does anyone out there have any advice as to how I can make this work?
    Thanks,
    Ian

    This is going to be a two-part solution, meaning you will need to change the way you read your file and the way you transmit the data.
    First, when you read from your file, set the Read VI to read in Line Mode. When you do this, the output of the read will be an array of strings rather than a single string. It will basically read the file until it hits the CR/LF combination, but should strip the terminating characters from each line.
    Second, in order to replace the carriage return which was stripped, you can configure VISA to transmit a termination character after each write is performed. In addition to setting the termination character to CR on the Configure Serial Port VI, you will want to use a VISA Property Node to set the Serial::End Mode For Writes properter to use the termination character.
    Now, you can simply use a For loop to index through your string array, transmitting each line. You will have eliminated all your manual parsing of the file, which should simplify your application and increase performance. I have included a picture of how this could be done in LabVIEW 8.x. The file I/O interface looks different than it did in 7.1, but the same functionality exists.

  • 64-bit Vista Drivers for PCI Serial device

    I've just got an T500 and put Vista 64-bit on it.  I've found (I think) all the drivers for it that it needs, except that there are 2 drivers in the Device Manager that show as not installed/needing update they are:
    Under Other Devices
     - PCI Serial Port
     - PCI Simple Communications Controller
    Anyone know what divers I should get to get these loaded properly or what devices/capabilities I am loosing because there are no drivers?
    Thanks,

    George, welcome to the forum,
    have you tried using ThinkVantage System Update to see if it can automatically find the drivers for you?
    Hope this helps
