Calibrating a 6552 using Cal Exec.

I am trying to calibrate a 6552 card.
What does Cal Exec mean when its asking me to "Select the switch device strings" "SCXI slot 0" and "SCXI slot 1"?
I have never seen this before?

Hi,
The "Switch in SCXI Slot 0" and "Switch in SCXI Slot 1" string entries show up in Calibration Executive's DUT Selection configuration window when NI 6551/6552 cards are being calibrated. They expect a string in the DAQmx format (e.g. dev0) and it should be the Device ID of the Switch. 
NI SCXI-1193 cards are needed for this calibration setup.
More information can be found on the help file of the Calibration Executive under "Calibration Executive Help - Device Calibration Procedures - Modular Instruments - HighSpeed Digital - NI 6551/6552 Calibration Procedure"

  • Testing the 4110 in Cal Exec 3.6

    We are trying to get rid of our XP computers so upgraded Cal Exec from 3.4.1 at the same time.  The new 4110 test has 4 added sections.  There is no README file so I am stumbling through.  First, I discovered that it really wants you to use the their PXI-4071 DMM.  Next,  I was able to step through and find that there are 10 new resistive loads I will need to complete the Load Regulation tests.  However, it chokes on Line Regulation.  At this point, it starts calling for an adjustable supply instead of the APS-4100 external supply that was used for all tests up to this point.  Of course, there is nothing to tell what supply it wants me to use.  Does anyone use this?  Can you fill me in on what additional resources are required?
    Thanks,
    George

    We just upgraded from 3.4.1 on an XP machine to 3.6 on a Win7 machine.  After I posted my question, I was given a link with all kinds of useful information.  It does not list the load values or show any connections, but it does list recommended equipment.  Great link: http://digital.ni.com/manuals.nsf/websearch/2742A60E930DE92186257CED0077EBB7
     

  • Calling a VI which uses "system exec.vi" with LabVIEW run-time engine as adapter

    Hi,
    My TestStand sequence calls a VI which includes a call to "system exec.vi". When I try to load it in TestStand and if LabVIEW adapter is set to run-time engine, I get an error message "Unable to load Vi...". If I switch the adapter to "Development system", then it works fine.
    Is there any way to use "system exec.vi" in a VI which is called in TestStand with LabVIEW run-time ?
    Thanks,
    Alex

  • Using Runtime exec() method to run java files and return runtime errors

    Hi
    I'm writing a java editor and I use
    Runtime.getRuntime().exec(command)
    to compile the java files. That works fine and I deal with the returned errors using the getErrorStream().
    My questions are:
    1. Can I use the same technique for returning runtime errors. In any posts I've read the process runs from begining to end, returning the errors after completion. How do I return the errors of the app as they happen interactively?
    2. If i cant use the exec and getErrorStream() methods then does anyone know how it is done?
    Thanks in advance for any help!

  • Parameter  to shell script using Runtime.exec(string)

    Hi all, ( Speciall hi to dheeraj tak )
    Briefly : How do i pass an arguement to a non - java executible being called using Runtime.exec.
    In detail : i am using Runtime.exec to call a shell script : The code is as follows:
    String callAndArgs[] = {"/home/tom/jakarta-tomcat-4.1.24/webapps/dash/script.sh"};
    try {
    Runtime rt = Runtime.getRuntime();
    Process child = rt.exec(callAndArgs);
    This works properly & calls the shell script which in turn invokes some other executible (c file).
    $HOME/midi/test/build/bin/<C-EXECUTIBLE>
    Here i am specifying the name (say hello.exe ) . So far so good.
    I want to make this happen dynamiclaly. so i need to pass the name of the executible as a parameter to the script.
    To pass a parameter i hav to change the string to :-
    String callAndArgs[] = {"/home/tom/jakarta-tomcat-4.1.24/webapps/dash/script.sh <C-EXECUTIBLE HERE>"};
    and the script to
    $HOME/midi/test/build/bin/$1 --- where $1 refers to argument 1. (C-EXECUTIBLE AGAIN).
    This is giving an IO - Execption. Plz help
    Code will be very helpful.
    Thanx in advance

    some 1 plz tell me the difference :-
    This is the documentation of Runtime.exec that i found :-
    1> exec
    public Process exec(String command) throws IOException
    Executes the specified string command in a separate process.
    The command argument is parsed into tokens and then executed as a command in a separate process. This method has exactly the same effect as exec(command, null).
    Parameters:
    command - a specified system command
    Complete refernce says : Process (String progName) ----- Executes a program specified by programname as a seperate process.
    2> exec
    public Process exec(String cmdarray[]) throws IOException
    Executes the specified command and arguments in a separate process.
    The command specified by the tokens in cmdarray is executed as a command in a separate process. This has exactly the same effect as exec(cmdarray, null).
    Parameters:
    cmdarray - array containing the command to call and its arguments.
    Complete reference says : Process exec(String comLineArray[]) ---- Executes the command line specified bythe string in comLineArray as a seperate process.
    This means that there is provision 4 command line arguments...
    how do u use it then????????????????????????????

  • How to run db2 command by using Runtime exec

    Hello
    I am using java. When i am runing db2 command by using Runtime.exec( String cmd, String[] env ). I gave the environment path
    DB2CLP=6259901
    DB2DRIVER=D:\ibm\db2\java\db2java.zip
    DB2HOME=D:\ibm\db2
    DB2INSTANCE=DB2

    but still I am getting error message

    after setting the above path in the cmd It is working fine. When i am trying thro java programm i am getting the above error. Can I get answer for this.
    bhaski.

    Before you can execute DB2 commands you have to open a DB2 CLP. The following code will do so:
    import java.io.IOException;
    public class Db2 {
         public static void main(String args[]) {
              try {
                   Runtime rt = Runtime.getRuntime();
                   Process child = rt.exec("db2cmd");
                   child.waitFor();
              catch (IOException io) {
                   io.printStackTrace();
              catch (InterruptedException e) {
                   e.printStackTrace();

  • Can we run a java application using Runtime.exec()?

    Can we run a java application using Runtime.exec()?
    If yes what should i use "java" or "javaw", and which way?
    r.exec("java","xyz.class");

    The best way to run the java application would be to dynamiically load it within the same JVM. Look thru the class "ClassLoader" and the "Class", "Method" etc...clases.
    The problem with exec is that it starts another JVM and moreover you dont have the interface where you can throw the Output directly.(indirectly it can be done by openong InputStreams bala blah............). I found this convenient. I am attaching part of my code for easy refernce.

  • Trying to run external script using Runtime.exec

    Hey,
    I am trying to use Runtime.exec(cmd, evnp, dir) to execute a fortran program and get back its output, however it seems to always be hanging. Here is my code snippet :
                Process process = Runtime.getRuntime().exec(
                      "./fortranCodeName > inputFile.txt" , null, new File("/home/myRunDir/"));
                InputStream stream = new InputStream(process.getInputStream());
                InputStream error = new InputStreamr(process.getErrorStream());
                BufferedReader stdoutReader = new BufferedReader(new InputStreamReader(stream));
                BufferedReader erroutReader = new BufferedReader(new InputStreamReader(error));
                System.out.println(stream.available());  //returns 0
                System.out.println(error.available());     //returns 0
                while (true) {
                    String line1 = stdoutReader.readLine();  //hangs here
                    String line2 = erroutReader.readLine();
                    if (line1 == null) {
                        break;
                    System.out.println(line1);
                    System.out.println(line2);
                }I know for a fact that this fortran code prints out stuff when run it in terminal, but I don't know if I have even set up my Runtime.exec statement properly. I think I am clearing out my error and input streams with the whole reader.readLine bit I have above, but I am not sure. If you replace the command with something like "echo helloWorld" or "pwd", it prints out everything properly. I also am fairly confident that I have no environmental variables that are used in the fortran code, as I received it from another computer and haven't set up any in my bash profile.
    Any Ideas?

  • Using runtime.exec,process streams

    Hi all,
    I am using runtime.exec to execute a batch file(rmdir /s/q directoryname) which deletes all the files in a certain directory(including subdirectories). However, some of the files are not deleted since they are being used by other processes.
    I have closed all file references but still the batch file says they are being used by other processes. The File.canWrite() method however, returns true for all the files. I have also tried to delete the files using file.delete but it does not work.
    So I have 2 questions.
    1. Can I forcibly delete these files some other way.
    2. If i call a batch file to delete the files and it fails on some files, the command window displays "cannot delete files". How can I write out thse messages into a text file which i can use as a log file.Do I have to use Process.getInputstream()/Process.getInputstream() ? If so, how?
    Thanks for your help.
    Vinny

    I tried the following before but the string i get is always empty, but i can see there are messages in the command window. Please let me now if i am doing something wrong.
    try{
    Process p = rt.exec("cmd.exe /c start deletefiles.bat");
    InputStream ins = p.getInputStream();
    byte[] bytearray = new byte[1024];
    int bytecount;
    String dos_string="";
    BufferedInputStream bis = new BufferedInputStream(ins);
    while ((bytecount = bis.read(bytearray, 0, 1024)) > -1) {
    String str = new String(bytearray,0,bytecount);
    dos_string += str;
    System.out.println("dos string is" +dos_string);
    catch (Exception e) {
    System.out.println("Error: " + e);

  • Using Runtime.exec to execute a C++ executable

    Hello,
    I would like to know if it possible to execute a C++ executable using Runtime.exec() and wait for it to complete and how do I read back the output file created by the C++ executable into the Java Code?
    TIA.
    RHP

    When I execute the code with Runtime.exec(), and read
    from the Process's inputStream I am ablt to view the
    cout from the C++ code. But the output file that has
    to be created by the C++ code is not created,Then this is maybe an error in the C++ code? Maybe you don't have permissions to create that file where you want to.
    where
    would the output from the C++ code go to when I use a
    ofstream in my C++ code andIf you create the file stream in C++ with an absolute file name then the output goes into that file. If it's a relative file name, then the basis is most likely the current working directory (found in the system property "user.dir" if you used one of Runtime's methods without the File argument, otherwise it's the directory you provide.
    How do I read both streams
    from the Java Code?You create an FileInputStream and - if you want to read character instead of binary data - on top of that an InputStreamReader. You might add a BufferedReader on top of that if you want to read line by line.
    does that answer your questions?

  • Using runtime.exec to zip some files

    Hi,
    I am using runtime.exec to try to automatically zip a bunch of files on a server. However, it does not seem to be working.
    Before I execute the command, I save the zip command in a string. I then print the string to a log file, and then execute the runtime zip command. But nothing happens.
    Yet, when I copy the string from the log, and paste it in a terminal, it properly creates the zip files. So, I know I have the correct command string, it just does not seem to be working within the java application. Also, the command string uses fully qualified directories, so it is not a directory issue.
    I am using ubuntu linux.
    Any ideas?

Within Runtime.exec() any command does not run in a shell and I bet you use wild cards and/or other commands to be interpreted by a shell which will not be interpreted since there is no shell. And, since you don't mention error messages or the return code, I will also bet you don't process the Process stdout , stderr and the return code properly.
    It looks to me like you have fallen for at least two for the traps in [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html].

  • Enter password to a program using system exec

    Hi,
    I have a program that I am running using SYSTEM EXEC.VI. The VI runs ok but asks me to enter a passowrd. If I do this, the VI continues and completes the test. My question is... how can I add the password automatically using SYSTEM EXEC.VI without the user typing it in. I have tried a carridge return and then the password (in the comand line) or even typing the password into the STANDARD INPUT and have even tried creating a batch file but no luck
    regards
    Chris
