Trying to Set up Shaker Table

Hi Everyone, I am a beginner trying to set up Labview to remote control a Troemner Orbital Shaker table. I am trying to use the basic serial write and read. I think I have selected the correct port because when I read the *IDN?\r\n it reads 22 bytes and says the Product is in Standby. Which it currently is. However if I take it out of Standby manually. And try to write again I get "Serial Prot Error, Input again please" with 41 bytes read. The manufacture supplied a Interface guide however I am not to sure how to use it properly.
I try and input 'I=*' and I get the same Port Error. I have attached the manual. If anyone can help that would be appreciated. 
Thank you

The manual doesn't tell what "Standby" does or doesn't do, as far as the interface is concerned.
 You said: when I read the *IDN?\r\n it reads 22 bytes and says the Product is in Standby. Which it currently is.
Can you do that repeatedly?
I mean, without taking the machine out of standby, does the message work again and again?
If so, then your comm link settings are likely OK.
If not, then perhaps there's something it doesn't like - maybe it wants \r instead of \r\n, maybe it needs some other delimiter.
If you have a terminal program, that might be a better place to start, just so you can establish the exact commands you need to send.
It's not difficult to write one in LabVIEW, or use a packaged one.
Just send whatever you type out the port, and whatever you receive, display it.

  • Getting error while setting color to table rows?

    Hi All
    I am trying to setting colors to table rows based on dropdown value.
    lv_Dropdown vaue =1 i want to set one color, 2-another color like that.
    For this I create attribute CELL_DESIGN of type WDUI_TABLE_CELL_DESIGN in node, and i bind this attribute to every column celldesign property in table. and my code in on select of dropdown.
      data lr_column type ref to cl_wd_table_column.
    data:obj_table type ref to cl_wd_table.
    lr_column = obj_table->get_column( id = 'TABLE_WEEK1' ).
    if lv_dropdown = 1.
       lr_column->set_cell_design(
    cl_wd_table_column=>e_cell_design-badvalue_dark ).
    endif.
    lr_column->bind_cell_design( path = 'SEGMENT1.CELL_DESIGN'  ). ...Giving dump at r_colum = get_column( )
    I follow correct code or not??
    Cheers,

    Sorry Sarbjeet and baskaran i am not getting,
    I want to set colors to row of a table on dropdown selection. In dropdown i ahve a code like
    DATA lo_nd_segment1 TYPE REF TO if_wd_context_node.
      DATA lo_el_segment1 TYPE REF TO if_wd_context_element.
      DATA ls_segment1 TYPE wd_this->Element_segment1.
      data lt_segment1 type wd_this->elements_segment1.
      DATA lv_segment TYPE wd_this->Element_segment1-segment.
    navigate from <CONTEXT> to <SEGMENT1> via lead selection
      lo_nd_segment1 = wd_context->get_child_node( name = wd_this->wdctx_segment1 ).
    get element via lead selection
      lo_el_segment1 = lo_nd_segment1->get_element( ).
      lo_el_segment1 = WDEVENT->GET_CONTEXT_ELEMENT( 'CONTEXT_ELEMENT' ).
    get all declared attributes
      lo_el_segment1->get_static_attributes(
        IMPORTING
          static_attributes = ls_segment1 ).
    DATA : lv_dropdown type string .
    lv_dropdown =  ls_segment1-segment.
    if lv_dropdown = 1.  SET ONE COLOR TO THAT ROW
    endif.
    if lv_dropdown = 2.  SET ONE COLOR TO THAT ROW
    endif.
    Now what should be the code in WDMODIFYVIEW method to set table row with colors.

  • HT1553 I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error...

    I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error... Help!!

    If you have installed a new hard drive , you will need to have formatted it in Disk Utility correctly. This may explain your problem.
    Boot  into your 10.6 Install disk again at the top menubar > Utilities > select Disk utility and in there select your new hard drive, and select the tab Erase and choose to make the format as  Mac OS Extended Journaled. When that is finished look in the main window to make sure that the partition map scheme says GUID Partition Table.
    Now go to the Restore tab and reinstall from your backup.

  • Trying to set a delay in an Applescript for VPN connection

    I need to be able to set some routes upon opening a particular VPN connection so I did some searching and found a really simple Applescript that does the job. Problem is it tries to set the routes before the VPN actually connects so the routes don't go in.
    I added in a 10 second delay which does the trick, but I'm thinking there has to be a way to do this that waits until the VPN actually connects before continuing - so if it takes 5 seconds or 10 or whatever, it waits.
    The other thing I'm doing that I think is bad is I'm sending a route delete command before sending the add command. Why? Because if I don't and for some reason the route is partially in the table, it doesn't give an error and ends up not routing. Again, probably a better way to do this.
    Here is my current script"
    -- Connect Work VPN
    tell application "System Events"
    tell current location of network preferences
    set VPNservice to service "Work" -- name of the VPN service
    if exists VPNservice then connect VPNservice
    end tell
    end tell
    delay 10
    set gateway to "x.x.x.x" -- omitted here for security
    do shell script "route delete 192.168.25.0/24 " & gateway with administrator privileges
    do shell script "route delete 192.168.20.0/24 " & gateway with administrator privileges
    do shell script "route add 192.168.25.0/24 " & gateway with administrator privileges
    do shell script "route add 192.168.20.0/24 " & gateway with administrator privileges
    Any suggestions??
    Thanks.

    you might want to try asking in the Applescript forum under OS X technologies.
    I don't have any VPN connections so can't test anything but applescript dictionary for system events indicates that configuration property of a service has a boolean property "connected". so just run a loop with, say, 1 second delay until this porperty becomes true. presumably it would be something along the lines

  • Informix: Error while trying to set up start or end key for index read

    Hi all
    Im moving an application from weblogic 6.1 to 8.1, we're using informix as our databasemanager and are using informix's XA driver. However im running into the following error:
    SQL State: IX000, Exception: java.sql.SQLException: [Internal] Error while trying to set up start or end key for index read [fmstopset_release],
    SQL ErrorCode: -9847, Error Message: [Internal] Error while trying to set up start or end key for index read [fmstopset_release], RSAM ErrorCode: -101
    ...while accessing a table.
    The same code runs fine twice, but the third and following times it fails with the above error code. I've tried setting the various XA flags available in the weblogic console but with no success so far.
    Anyone have any input to this problem? Ive not seen many postings about this error out in the cyberspace and the fews ive seen never gets any response...so i just have to hope anyone in here know anything about it.
    Best regards

    Hello
    I managed to work around my problem by setting the "statement cache size" in the jdbc connection pool to 0. At least that seems to be a work around, im not fully happy with it.
    I attach the stack trace from the exception, perhaps it will give someone an idea.
    Btw, we're using sun.jdbc.rowset.ExtendedCachedRowSet to populate the resultset to a "disconnected resultset" which the application works with instead of the resultset. Any statements and resultsets that are created are closed before returning the ExtendedCachedRowSet to the application.
    If the application works when statement caching is turned off, then it implies a bug in the
    informix driver to do with re-using a prepared statement. Is the PreparedStatement used
    the same way each time? (the one at AbstractDAO.java:166) What I mean to ask is, If/when
    this statement is created with a given SQL string, are the parameters for that SQL always
    set the same way?

  • Object Open Error while trying to export the vDataFact table

    I am getting an error when trying to export the vDataFact table to a flat file.  I have been able to do this several time before with the segment tables but would like to run this against vDataFact

  • Trying to set an email address

    I am using Oracle 9i and SQL*Plus on Windows XP.
    I am trying to set an email address in my object table using an object method.
    I have the following types:
    CREATE OR REPLACE TYPE student_type AS OBJECT
    (FirstName varchar2(15),
    LastName varchar2(15),
    Address address_type,
    Contact contact_type,
    DateOfBirth date,
    Nationality varchar2(15),
    AttendanceMode varchar2(15),
    StudentNo varchar2(15),
    Userid varchar(15),
    FeeStatus varchar2(25))
    create type contact_type as object
    (home_tel_no number(14),
    mobile number(14),
    email varchar2(25))
    and have created a method to set an email address:
    MEMBER FUNCTION setEmail (self IN OUT student_type, em varchar2) RETURN number,
    PRAGMA RESTRICT_REFERENCES (setEmail, WNPS, RNPS)
    along with all of the other necessary code which works OK.
    I have implemented it with the following code but am not sure if it is correct:
    MEMBER FUNCTION setEmail (SELF IN OUT student_type, em varchar2) RETURN NUMBER IS
    BEGIN
    SELF.CONTACT.EMAIL := em;
    RETURN 1;
    END;
    but when I try to run it, i get the following error:
    SQL> SELECT S.SETEMAIL('[email protected]') FROM STUDENT_TABLE S WHERE FIRSTNAME = 'Sammy';
    SELECT S.SETEMAIL('[email protected]') FROM STUDENT_TABLE S WHERE FIRSTNAME = 'Sammy'
    ERROR at line 1:
    ORA-06572: Function SETEMAIL has out arguments
    Any help with this would be great.
    James

    SELECT S.SETEMAIL('[email protected]') FROM
    STUDENT_TABLE S WHERE FIRSTNAME = 'Sammy'
    ERROR at line 1:ORA-06572: Function SETEMAIL has out arguments
    er...that'll be because your member function has an OUT parameter, self:
    MEMBER FUNCTION setEmail (self IN OUT student_type, em varchar2) RETURN number,(1) You need to reference all parameters in the function, so you need two arguments in your call - but...
    (2) we cannot use methods with OUT parameters in SELECT statements, because that's the law.
    Do you need to pass SELF into your method? If so you'll have to use PL/SQL to do this instead.
    Looking at your code again, I see you are actually using a SELECT statement to alter the data iin the database. This is not allowed at all. SELECT statements are, must be, read only.

  • HT4759 I am trying to set up icloud on my Macbook. I was using the step by step guide on your site but when I open system perferences I do not have the icloud icon under internet and wireless. How do I get it?

    I am trying to set up icloud on my macbook, I was using the step by step guide on the site but when I try go into system perfences in there is no icloud icon under internet and wireless. How do I get it?

    This is presumably because you are running an earlier system than Lion. (Please always post your system when you have a question.)
    The minimum requirement for iCloud is Lion 10.7.5 (Mavericks preferred): the iCloud Preference Pane does not appear on earlier systems - the MobileMe pane appears on Lion and earlier but is non non-functional - you cannot now open or access a MobileMe account.
    To make use of iCloud you will have to upgrade your Mac to Lion or Mavericks, provided it meets the requirements.
    The requirements for Lion are:
    Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
    2GB of memory
    OS X v10.6.6 or later (v10.6.8 recommended)
    7GB of available space
    Lion is available in the Online Apple Store ($19.99). Mountain Lion (10.8.x) is also available there at the same price but there seems little point as the system requirements are the same for Mavericks (10.9.x) - which is free - unless you need to run specific software which will run on Mountain Lion only.
    The requirements for Mountain Lion and Mavericks are:
    OS X v10.6.8 or later
    2GB of memory
    8GB of available space
      and the supported models are:
    iMac (Mid 2007 or newer)
    MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    MacBook Pro (Mid/Late 2007 or newer)
    Xserve (Early 2009)
    MacBook Air (Late 2008 or newer)
    Mac mini (Early 2009 or newer)
    Mac Pro (Early 2008 or newer)
    It is available from the Mac App Store (in Applications).
      You should be aware that PPC programs (such as AppleWorks) will not run on Lion or above; and some other applications may not be compatible - there is a useful compatibility checklist at http://roaringapps.com/apps:table
      If you are running Leopard on an Intel Mac you will have to upgrade to Snow Leopard to access the Mac App Store - it's available in the online Apple Store. However if you have a PPC Mac you cannot run Snow Leopard and cannot proceed further.

  • Catalog Characteristics - trying to set att to standard characteristic

    Hi,
    we are using CRM 5 and I have just created our first B2C Catalog. All is well apart from one area around the characteristics. I have created a new characteristic and attached the attribute and set type I created. However the attr type is automatically setting to master characteristic which is causing me an issue. I want to be able to maintain this characteristic only in the catalog for each product (not relevant to ERP) so it would make sense to set this to standard characteristic - but I cant!
    The attribute and set type are simple and is only simply a character string (1) with no links to the database tables - so why wont it allow me to change this?
    Any ideas?
    Regards
    Paul

    Hello Paul,
    Are you trying to set a characteristic value in the catalog that is different from what is set in the product master?
    Are you expecting them to behave like configurable products?

  • I am trying to set up Sharing amongst several computers on my home network.  I have followed all the setup instructions but after completion Sharing does not appear in my iTunes window (on any of the computers I've set up).  There is no explanation why.

    I have been trying to set up Sharing between two computers on my network. I did this once and it worked.  However, when I try to set this up now the Sharing feature does not appear on the left side of the iTunes window (on either computer).  There is no explanation as to why not.  Is this a configuration problem, a network problem or what?   Can it be fixed?  I have tried turning sharing off and back on on both computers but to no avail.  What am I missing?  Thanks for any help you can provide.

    Hey innerev2003,
    Thanks for the question, and welcome to Apple Support Communities.
    If, while searching through your past purchases, items are unavailable to download and show a "Purchased" button, they are still on your computer. It may be best to search your iTunes library by clicking Music, then use the search bar at the top right.
    If you are completely sure the items are no longer in your library, try signing out of the iTunes Store, and then back in.

  • A pop-up message is frozen on my settings page. I was trying to set up an apple id for iTunes when I got a message "required fields have been left blank. The missing information is highlighted in red." the ok button doesn't work. 1st gen iPad.

    A pop-up message is frozen on my settings page. I was trying to set up an apple id for iTunes when I got a message "required fields have been left blank. The missing information is highlighted in red." the ok button doesn't work. The message is now fixed &amp; I cannot get rid of it. Ironically, when I found this forum I was able to set up an apple Id. Please advise how to get rid of the pop-up box. Thanks!

    I'm having this same problem as well and cannot advance--very irritating. All of the information is filled out correctly and I've editted my AppleID information online separately as well to get around this issue, but no luck...
