MATCHING GPS AND PC CLOCK

Hello.
I have a GPS Encore connected to my PC and I´m getting
the time information of the GPS in LABVIEW. I want to match
the PC clock to the reading I get from the GPS. How
do I do it in LABVIEW?? Is there a command so I can set
the PC clock time at my owne will??
Thanks in advance

This is relatively straight forward:
Get a Call library function (from the advanced menu).
Right click and go to configure.
A pannel will appear, starting at the top:
Library: C:\windows\system\kernel32.DLL
Function name : SetSystemTime
Calling convention : StdCall (WINAPI)
Below this there will be a parameter called Return - rename this ERROR.
Set the parameter details to Numeric and Signed 32bit Integer. If the returned value is NON zero, the command was successfull.
Click Add Parameter.
A new parameter will appear called arg1 - rename this to SYSTEMTIME.
Set the type to 'Adapt to type', and the value to 'Handles by Value'.
Finally, set the function to be REENTRANT (top right listbox).
You can now press OK.
The Call Library function will have changed to refle
ct the configuration.
The SYSTEMTIME variable is a cluster of 8 signed 16bit integers. To set the time, the values should be as follows:
Year (yyyy)
month
Day of week (ignored - windows decides this)
Day
Hours
Minutes
Seconds
Milliseconds
Happy programming

  • An appeal to Nokia - GPS and time

    This is an appeal to Nokia to create products that make use of the fact that GPS receivers can give accurate time.
    I'm an amateur astronomer, and GPS and Java-enabled mobile phones are an absolute godsend - I can whip out my phone and, with a built-in GPS and the right software, it will figure out where I am and hence what is visible in the sky.
    EXCEPT that what is visible in the sky is also dependent on the time. And sometimes, having access to accurate time can make all the difference.
    For instance, I am currently working on updating software I wrote to calculate the circumstances of total solar eclipses - something that a GPS-enabled mobile phone is perfect for. And a couple of seconds error in the phone's clock can make all the difference.
    So please please Nokia make use of the fact that GPSes can give (astonishingly) accurate time.

    To sync to GPS time on your Nokia phone, you need either Free TimeSync or FreeTimeBox, 
    These are free ware apps which allow you to sync to GPS time.
    here's a link to Free TimeBox 
    http://nucellphone.com/freetimebox-v1-06-for-nokia-s60v5
    Its the newest version compatible for s60v5, but AFAIK it should work on non touch phones as well.

  • Issue with the functions "add matching sets" and "modify matching sets"

    Hi,
    Though 'None' access permission is set for the functions 'Add Matching Sets' and 'Modify Matching Sets', they are accessible.
    Is this a bug with the tool? or am I missing something?
    Thanks in advance,

    sorry, missed the version details.
    I'm using MDM 5.5 SP6.

    How old was this backup? It sounds like it was at least several weeks old.
    You can look directly in the TM backup for the music.
    1. Connect to the external HDD the backup is kept on.
    2. Open a Finder window and select the backup drive in the left hand panel. Double click into the folders until you see a list of folders with dates.
    These are the incremental backups. You can start at the top or the bottom of the list but I suggest you double Latest/<HDD Name>/Users/<Account Name>/Music/iTunes/iTunes Media/Music. From this location you can start looking for the "missing" music. When/if you find it you can simply drag-n-drop to ~/Music/iTunes/iTunes Media/Music on the internal HDD.
    If the music is actually not in the backups (for whatever reason) then you've got a problem.
    You can download the uploaded files from the cloud by deleting the affected tracks from the iTunes library (but not the cloud!), highlighting multiple tracks at once, right-clicking and choosing "download."

  • Matching Raster and Vector RGB color in InDesign CS3.

    We print on a Durst Lambda RGB imaging device to photographic paper. All color management is done as an early bind (raster files are converted to the printer's color space and vector colors are chosen from a palette database). So basically the files must go through InDesign without any color change in raster or vector information. We have clients that require specific RGB builds for logo colors the are present in both their raster and vector files.
    Color Management is set to "North American General Purpose 2" with "RGB: Preserve Embedded Profiles" selected.
    1) The file is exported as a PDF 1.4, High Quality, PDF/X_None.
    2) The PDF was ripped on a Cheetah RIP (Jaws level 3) with no color management on.
    3) Solid raster colors such as 0-255-0 will reproduce as 0-255-1.
    4) The color differences between the raster and vector are usually 1-4 points.
    5) The vector is consistent as was input in the programit's only the raster that changes. When you are trying to match raster and vectors logo colors it is a killer.
    However, I can go into the InDesign (or Illustrator) color settings and turn color management off (This is our current workflow). In doing this the RGB working space uses the monitor profile and "color management policies" are set to OFF. With these settings the RGB raster and vector match. The problem with this work flow is two fold:
    1) We have other devices than our RGB Durst Lambda that can use the InDesign color managementVutek flat bed 3200 and grand format 3360.
    2) We have had many occurrences where the custom "color management off" settings have reverted back to the default "North American General Purpose 2"without any intervention.
    I have tried this with different RIP's with the same results.
    Does anyone have an idea to create a simple PDF workflow and keep the color information consistent?
    Program: InDesign CS3 5.0.2
    Platform: Mac OS 10.5.2
    Computer: G5 tower with 4 gigs of RAM

    I believe that setting is an old Illustrator setting that has been saved to effectively turn the color management off. The monitor profile effects the image displayedit doesn't effect the color transform.
    Anyway, the color management I want to use is the "North American General Purpose 2".
    To reiterate:
    The procedure:
    1) The file is exported as a PDF 1.4, High Quality, PDF/X_None.
    2) The PDF was ripped on a Cheetah RIP (Jaws level 3) with no color management on.
    The Problem:
    3) Solid raster colors such as 0-255-0 will reproduce as 0-255-1It changes from the original raster color placed in InDesign.
    4) The color differences between the raster and vector are usually 1-4 points.
    5) The vector is consistent as was input in the programit's only the raster that changes. When you are trying to match raster and vectors logo colors it is a killer.
    To summarize, the color of the raster file will change from the original that was place into the documenteven though nothing was selected in InDesign that would change the color (i.e. profile conversion to an output profile or a transparency effect used). The change is slightbut there.

  • My imac won't start up past the grey screen, apple and spinning clock

    Hi there.  First time posting - usually either apple support website or previous threads solve the problem.  Alas, not this time.
    I have an intel imac - can't tell you much about the details as I can't get any info out of it.  I installed snow leopard about a year ago - no issue since then other than occassionally the screen goes black but nothing major.
    Yesterday, I backed up to my usual passport backup and then today, it froze.  I couldn't turn it off or restart at all so resorted to the power button.  Since then, I can turn it on, it goes to the grey screen (no blue screen) and I get the apple logo and the spinning clock/wheel.  For hours and hours....
    So, I tried one of the apple support pages and worked through - peripherals, safe boot, NVRAM, PRAM, tried to reboot with mac osx disc (the original not snow leopard) - nothing.  Absolutely nothing changes - same old grey screen, apple logo and spinning clock/wheel. 
    HELP - do I try and reboot with the snow leopard disc?  I don't know what to do next - I am no techie so half the threads don't even sound like English to me.
    Thanks in advance, hope you geniuses out there can help me out.
    abcvic

    Thanks for the reply.
    I had tried to reboot with the original disc but it never worked. The imac just spits out the disc and eventually, I am back at the grey screen, apple logo and wheel spinning. I tried it one more time following your reply. Same outcome.
    My instal disc 1 had the instruction re hardware test which I have also tried with no success. I can't remember if it came with a disc 2 though I seem to have a couple - I also have a macbook and that seems to be still alive even if it is slow.
    I tried to reboot with Snow Leopard disc - power on, chime then hold down C key. Same old - grey screen, apple logo and wheel spinning. Disc spat out eventually.
    Any other suggestions welcomed or I am off to Apple tomorrow.

  • How to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-60​15)

    Hi,
    Can someone tell me how to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-6015)?
    Thank you very much.
    Jack

    John --
    Windows is not an option for me. I like your idea of using a counter output -- it may be helpful as I am getting ramped up, but my application will eventually require both timer outputs.
    I have a legacy C application written for Macintosh, and I am in the process of moving it onto OS X. So my options are to use DAQmx Base, or write an in-kernel driver. I actually have already done the latter for 6024/6025 E-series boards (for another company); for this client I was hoping to use the DAQmx Base to allow an easy transition to M-series boards, without the cost of writing and supporting a low-level driver.
    The specific task I am doing is relatively straightforward. I record 2 channels of AI for a short period (usually about 250 ms.) and during this time I drive 2 external digital signals. Right now, I use the 2 timer outputs, which allows precise synchronization with the output and AI sampling.
    I appreciate your comments, and thanks in advance for any additional suggestions you can lob my way.

  • FI and PCA doesn't match/Receivables and Payables?

    Hi!
    I have a problem with Profit center accounting. I try to match receivables and payables in FI and PCA, but they don't match (transaction KE5T).
    If I look transaction 1KEK, e.g. account xxxx shows 500.000 EUR. When I look e.g. transaction FS10N, the same account shows 800.000 EUR (cumulated balance).
    So all the entries have not transfered to PCA from FI. Whe have done the period-end transfers (transactions 1KEK and 2KES).
    So why not all the entries have transfered to PCA and how to fix this problem?
    Points will be given!

    Hi
    Please ensure that the referred GL account is added in T.Code 3KEH.
    If not, you have to add the same with a default PC and need to post all the existing documents posted in that GL account, manually to PCA using t.code 1KE8.

  • Pearl with gps and wi-fi

    hiya,
    does anyone know a way to get both gps and wi-fi in a pearl?  gps or wifi addon/card to supplement the missing feature in one of the current pearls? just wait and see if they ever do it? 
    thanx, bradt

    Hi there,
    I'm having exact the same issue with my iPhone4 and IOS 7.04. I upgraded to 7.1.1 to see if this would fix my GPS problem. Unfortunately it's not resolved by the upgrade. I've tried everything I could and found on the internet, but nothing helped me out. All other location services work when it comes to global positioning. But when it comes to more accurate positioning it failes and is way off. When I use the free app GPS Status it gives me the same results as you describe: 1,141m off and before it was much more accurate. The only way to get GPS accurate is to connect to a WiFi-hotspot.
    Open for any suggestion.
    Thanks in advance.

  • Using Nokia 5800 GPS and accepting a call

    Hi, I was wondering if there was a way to answer calls while the GPS is on on my Nokia 5800 Navigation Edition.  Currently, when I use the GPS and someone calls, I tap the answer button, but I get a message that says not allowed.  I was looking around in the settings, but can't find anything.  I was hoping there would be a way to answer the call and turn on the speakerphone so I can drive and talk at the same time.  Anyway know if this is possible?
    Thanks!

     Getting my first call during active turn-by-turn navigation, I wondered about this strange behaviour too. As it is I dont see any green phone icon on the navigation screen. With the terminal placed in the included windscreen fixture, it is hardly traffic safe to have to press many buttons to get the handsfree activated! Nokia could consider another option on the main screen when a call is waiting to be accepted, for going directly to speakerphone-mode, or at least a configurable option within the maps application. As of now it jumps back to the maps app, which induces the added (two) press of the application switch button. I suppose buying a separate handsfree kit might 'solve' this basic issue, but that should really not be needed out-of-the-box with a dedicated navigation edition. If someone figures a setting that I have overlooked, I would be pleased to get a hint, thx.

  • IMac starts with sound but remains with Apple logo and the clock running indefinetely

    After software upgrade ( from mavericks to new mavericks ) iMac doesn't start anymore. It remains always in the same mode: after the sound of start the Apple logo and the clock that runs indefinitely without the start of the software. Someone knows what to do?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

    HI,
    Service Contract can be for a specific customer
    The contract type cound be (Coverage):
    1. including all items (Type Customer) in this case the dates of the coverage is defined in the head!
    2. Including specific serial numbers
    3. Including item groups
    The status every case should have to be Enabled/Approved  for valid contract (OCRT.Status = 'A').
    In case of Do not forget to set the valid from and valid to dates to define in the system the coverage. (header and items tab from/to dates)
    Now, If you create service all, the system will use the first possible Service Contract. IF you have more: you have to select the contract manually.
    Ex:
    1. One for customer including all items
    2. One for a specific serial number
    Best Regadrs,
