How sync two 9237 units?

Hello

I am writing an application in c# .NET using the DAQMX library, and I have 8 strain gauges, that I need to measure using two NI 9237 units connected by USB to my computer.

The problem that that I am facing is that the timestamps of the samples read by both units appear to differ slightly from each other.

I couldn't measure both units in a task, so I created two tasks.

As a test, I start both tasks and measure data for a few seconds. During this session, I plant a solid kick in the mechanical structure that the strain gauges are mounted to.

When I look at the data, I see that this kick is measured at different stamps for the two tasks, although the should be approximately the same.

I did not do anything to ensure that they have been synchronized, I assumed they were - at least roughly, but I got gaps more 160ms apart to 2 kHz.

The NI 9237 uses an internal clock, I read, so the question is:

Is it possible to synchronize the two units without any additional hardware and how?

I searched the forums and google but more related info were that 9237 synchronizes well with other units that use external as clocks time base because 9237 uses an internal clock.

The employee OR you talked on the phone is OK.  Now to synchronize two NI 9237 s in DAQmx, the only consists of one or more Compact DAQ (cDAQ-9172) chassis.  The USB-9162 carrier and NI 9237 have boundless to import a time base, sample clock or a trigger.  There is no way to make a chassis at two locations with two USB - 9237 s.

    Dear all,

    Please explain, how the two values of function return?

    give a simple example.

    OK, a few examples...

    First example, using a type of structured on the database object:

    SQL > create or replace type tMyValues as an object (yr number, number, number of dy mn)
    2.

    Type of creation.

    SQL > create or replace function getMyValues return tMyValues is

    number of 3 m: = extraction (sysdate months);
    number of 4 d: = extract (day of sysdate);
    5. start
    6 return new tMyValues(y,m,d);
    7 end;
    8.

    The function is created.

    SQL > set serverout on

    SQL > declare
    2 myValues tMyValues;

    Because I did the same job shaped a lot of my system. its fine to work with me.

  • Firefox Sync, two desktops computers and an android

    I currently have a Galaxy S5 (Android OS) and your desktop running Windows 7. The two devices sync properly. I now have another desktop computer and I would like to sync as well. On the primary computer. I go to the synchronization options and select manage. I get to the page manage account. https://accounts.Firefox.com/settings On this page, it shows that I am connected and gives me two options. Change my password or delete the account. There are no options to pair a device, get a security code or do something else that these two options. If I go to a desktop computer that has not been synchronized and I select the sync option, then I have already an account, it gives me the codes to pair a device but as I said, I have no pair option the main computer. If I select I don't have a camera with me, I have an option to connect you with an account and a password, but she wants too, then a recovery key that even once, I don't have the option to recover. At this point, it seems that synch can connect two devices. I studied the issues and extensively used search engines. Most keep responses pointing to the same items on how to synchronize the devices and the instructions never apply to this particular situation. Still once, I come back to the appearance page manage them has more options as did not in all other articles.
    I hope there is a solution to this problem.

    Firefox 29 and later have a new synchronization version that uses an account of Firefox and use only the name and the password and no longer use a sync (recovery) separated key (the key of synchronization is derived automatically the Firefox account password).

    The new synchronization version is completely different from the version that was previously used, and you must install a later version or Firefox 29 on all connected devices.
    You can enter the name and password of the Firefox account on each computer to connect to the new sync account.
    You can pair is more than a new device by entering a key to pairing on a connected device.

  • What happens if I sync two firefoxes Office? My Favorites will be organized by computer or are there duplicates?

    How to set up firefox sync is well described, but there is virtually no information on what happens after the installation. I have two computers with different bookmarks and settings and I want to keep it like that, but I still want to have access to the data of the other computer.

    Synchronization will import all the settings and merge or settings remain separated somehow? This will affect only bookmarks or also of the sessions, i.e. the open tabs and windows? I would agree with merging of bookmarks, but browsing sessions must remain unique, although it would be nice to somehow access the list of the tab open on the other computer.

    Firefox Sync "synchronizes" data types, the user selects on connected devices.
    If you select bookmarks in sync settings, your bookmarks on this device will be synchronized with those on the server. If favorite is not enabled on a particular device, bookmarks on this device are not part of each synchronization session.
    If you only select tabs you want to synchronize, your story will not Sync-only what is selected on a device will be part of each synchronization session.

  • How to remove the units listed in the window of the autorun program

    Does anyone know how to remove the automatic launch of units? Earlier, I installed several of my old mobile phones, which I don't use anymore, but when I open the autorun program, they are listed (some several times) and I can't seem to uninstall. Would be very happy if someone knows how to solve my problem. :)

    Original title: Wireless units in autorun

    Hi Bijei,

    • It is a program to AutoPlay or AutoRun?

    I suggest you open the editor from the registry on your computer and check in below location if the old mobile entries are listed. To open the registry editor follow the steps below:

    a. Click Start.

    b in the start search box type regedit and press to enter.

    (c) in the registry editor, navigate to the following location.

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoplayHandlers\KnownDevices

    or

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoplayHandlers

    d. Locate the old entries from mobile device to the above address.

    If you are able to find the entrances to the location above, you can click with the right button on the mobile device entries and remove entries. After you delete the key, restart the computer and verify if they appear in the list of AutoRun again. Before you remove the key make sure that you back up the registry keys.

    Registry warning:

    Sometimes, this problem is due to two Windows that have been corrupted registry entries. To resolve this problem, you must use the registry editor to delete the corrupted registry entries.

    However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

    For more information about how to back up and restore the registry, proceed as in the KB Article:

  • Please specify how sync works - I can't find a clear explanation anywhere! Parameters are be replaced? I think I lost a few bookmarks during a sync?

    I have 3 copies of firefox. I want all 3 to keep the same settings, bookmarks, etc.. When I open my browser in A device, and it starts to 'synchronize', it download my current settings for a server, or is it download the settings from a server?

    If I add bookmarks to firefox in the device, & then I add bookmarks and change some add-ons for firefox in device B, all the bookmarks and the modules will integrate? Or is the server by replacing the previous information from the device?

    My browser is not automatically connected whenever I open it. That's why I have lost a bookmark or two during the last sync I did? There is an error message telling me to re - connect with sync, & I don't always immediately.

    Is the problem that my password is not saved. I don't want Firefox to save passwords of websites.

    Hi alyab987,
    All parameters are the merger on the server and then distribute the merged at each Firefox facility attached to your sync account.

    Each of them will merge. It will only merge the settings that are selected to sync.

    Sometimes, the account will be dislocation. It is possible to test this by enabling / disabling or not Firefox stores passwords. I don't know what caused your computer disconnect.

    In order to disable the synchronization of your account passwords, click on any Firefox menu, then sync account name. Just make sure that the "passwords" are unchecked.

    I hope this helps.

  • How do two users share a computer (music, photos) in a single library but have separate iPhones (applications, contacts, etc.)

    I've hunted around so apologies if the answer is already pluse...

    My wife and I have an iPhone each. We have our own applications, contacts, e-mail, reminders, calendars (a little shared via iCloud for family stuff). We have a Mac. We want to be able to share a unique music library (caps to synchronize the different slopes for different phones) and a unique photo library. Until recently, I did this by moving the two libraries on a partition separate without permissions etc. I could connect to a user account for me and access, then log off and log in as my wife and access. Do not change fast and really I'm only using my wife log in as a place to save his iPhone, app, contacts data backups, etc. This is already in the iCloud.

    However, with the new application Photos it seems that you can share is no longer a single library between two users. I get permission errors every time that I load it. I connect both my wife, get the error, run 'repair permissions', then it opens. I go back to my account and now I can't open it, have once again to 'fix' etc.

    So the questions:

    1. is it possible to still share a unique between two accounts photo library, so that we can each backup / synchronize phones separately?

    2 - is the best way to do it? Historically, I guess I need two accounts on my mac to keep our separate data, but is it possible to have two iPhones sync for the same account, but keep things like contacts, separate application data, etc.?

    Thank you

    Gareth

    1. is it possible to still share a unique between two accounts photo library, so that we can each backup / synchronize phones separately?

    Yes. The way to deliver two users share the same Photos and iTunes without permissions library library (but only one user can access the library at the same time) is to put the library on an external hard drive that is formatted as shown in this screenshot and directly connected to the Mac via the USB cable Firewire, or Thunderbolt.

    Each would have its own account on the Mac so keep separate e-mail, contacts, etc.  Fast user switching can be configured, so it's easy to quickly switch between accounts.

    But when you are finished with the library each user must leave Photos if the library is available for the other user.
