What is the purpose of the 1394 and USB jacks on the 30" Cinema?

I have a 30" Cinema display connect to my (current-model) Mini via the Thunderbolt port and an Apple Dual-DVI adapter.
The back of the display has a pair of USB jacks and a pair of Firewire jacks, and the adapter has cable connections to match. What is the purpose of all these connections? I can tell you right now, it seems that nothing is coming or going through any of these paths. The Cinema display is working just fine but these miscellaneous connections aren't live as far as I can tell.
What would be great is if the FW tail on the adapter could be used as a second FW port for the Mini. Can that be made to work? Is there some way to route a FW signal to the Displayport?
TIA for any thoughts on this matter.

If I have to connect one  Cinema FW port to the sole FW port on the Mac Mini, that doesn't gain me any additional ports--it consumes one of two ports and leaves me a net of one open port--the same quantity I started with.
The display's FireWire cable (not one of the ports on the back of the display) connects to the computer's FireWire port (via a FW400 to FW800 adapter).  This uses up one computer FireWire port, but the display has two FireWire ports, so you gain one port.
It's the same for USB.  You lose one port of the computer but get two on the display.
BTW, your response implied that the Thunderbolt port "contains" both USB and FW connectivity. Can I simply tap off the FW and feed my external FW hard drive directly from the Thunderbolt port?
Thunderbolt doesn't include USB and FireWire directly.  Instead it includes a version of PCI.  Apple is making some simple Thunderbolt to FireWire or Internet adapters, but they have only one Thunderbolt connection, so if you used one, there would be no place to connect your 30" display.  (The HDMI port is limited to 1920 x 1200, so cannot drive a 30" display at full resolution.)
Belkin is coming out with an adapter that you could use, but it is not cheap.

  • What is the purpose  of Date From and Date To In Oracle HRMS ?

    hi
    I have doubt on
    What is the purpose of Date From and Date To In Oracle HRMS?
    Thanks

    Where do you see these fields? Please give full details (eg, the navigation path).
    If you're referring to Effective Start Date and Effective End Date (effective_start_date, effective_end_date) these are two fields that appear on many HRMS entities. They're used to store dated history over time. For example:
    14-Jan-2009 to 19-Apr-2009 - Pam Stephens
    20-Apr-2009 to date - Pam Erickson
    In this example Pam got married on the 20th April 2009 and changed her surname from Stephens to Erickson. Here the history of changes are kept so that if we date-track to any time prior to the 20th April 2009 we'll see Pam Stephens and if we date-track on or after the 20th April 2009 we'll see Pam Erickson.
    Check out the following Oracle Support article for more information:

  • My MacBook Pro with Lion 10.7.2, only audio on the headset, and speaker mute. With Windows, the audio works in speaker and headphone jack. What is the problem? What's the solution?

    My MacBook Pro with Lion 10.7.2, only audio on the headset, and speaker mute. With Windows, the audio works in speaker and headphone jack. What is the problem? What's the solution?

    There is probably a red light on inside your headphone port, indicating that the analog/digital switch in there is stuck in the digital position. Insert a headphone plug and wigle it around, especially in the horizontal plane, as you insert and remove it several times. This will usually unstick the switch and restore normal operation. If it doesn't, the machine will need to be repaired.
    This has been a fairly common problem, but in most cases it is easily cured as described above.

    Typically this indicates a device that has been hacked to be unlocked or jailbroken.
    If that is the case, no support can be provided here.

  • What is the impact of business area and cost center in the sales document

    Hi all
    I have small doubt regarding what is the impact of bussiness area and cost center in the sales document... what is the uses of these (bussiness area, cost center) is help full for sd module
    can any one reply plz....
    Thanking you

    Hi,
    Business Area determines where the revenue should be allocated when you sell a material or a service.
    For eg: If your customer is in say Mumbai and he is ordering for a service in Delhi (say DIAL - Delhi International Airport Limited) then based on the terminology.
    Your customer would belong to B Basis Business Area - WHERE THE REVENUE IS COMING FROM or WHERE YOUR CUSTOMER BELONGS TO (SALES OFFICE).
    Whereas your DIAL sales will belong to A Basis Business Area - WHERE THE REVENUE IS GOING TO.
    Cost Center would determine where your allocate your cost to.
    Say Rounding Off can be used as a cost element, because some sort of revenue is lost when figures are roudned off..
    Hope it clarifies your doubt.
    Reward points if satisfactory
    Regards

  • What's with the new Firefox 8.0? I made the mistake of updating mine and about 30% of the icons in bookmarks disappeared. It looks like you are requiring a favicon. Anyway, BAD IDEA!!!!!

    Briansyddal - you might be able to manage your phone without a PC, but many of us can't, especially those of us with large iTunes libraries.  How do you propose I manage my 250GB of music using only a phone?  Maybe I could go out and buy 10 iPhones and spread my library out among them!
    Catz537 - I have the same problem as you and I've spent hours on the web trying to find a solution to it.  It was a problem with iOS 7 and  8.1.1 doesn't fix it.  The the only advice from Apple is completely useless because it requires you, effectively, to delete and recreate your iTunes library and lose all your metadata, album art, notes etc and there's also no guarantee it will work.   I wish I could be more help (even more - I wish Apple could be more help) - I updated to 8.1.1 at 1400 today.  At 2200 I'm still "waiting for changes to be applied" for a measly 16GB of music transfer. 

  • HT5037 when I click on iPhoto(9.5.1)  i get "To open your library with this version of iPhoto, it first needs to be prepared." but i downloaded the up-grader, used it and it tells me the library can open with the current version... what should i do now?

    When I click on iPhoto(9.5.1)  i get "To open your library with this version of iPhoto, it first needs to be prepared." but i downloaded the up-grader, used it and it tells me the library can open with the current version... Then when I click on the iphoto again i get the same message "To open your library with this version of iPhoto, it first needs to be prepared."'
    What should I do?

    The upgraded is only necessary for libraries created with iPhoto '07 or eearlier.  Just double click the library to open it in iPhoto, and let it upgrade, if it has been created by a newr version.

  • What is the use for lock object and how to use the lock objects

    Hi Guru's,
    I am new to ABAP .Can you please clarify the that what is the use of lock object and how to use the loct object .what is use of the Deque & Enque  function modules .

    hi ,
    below are some minfo about lock objects :
      Lock Objects
    These types of objects are used for locking the access to database records in table. This mechanism is used to enforce data integrity that is two users cannot update the same data at the same time. With lock objects you can lock table-field or whole table.
    In a system where many users can access the same data, it becomes necessary to control the access to the data. In R/3 system this access control is built-in on database tables. Developers can also lock objects over table records.
    To lock an object you need to call standard functions, which are automatically generated while defining the lock object in ABAP/4 dictionary. This locking system is independent of the locking mechanism used by the R/3 system. This mechanism also defines LUW i.e. Logical Unit of Work. Whenever an object is locked, either by in built locking mechanism or by function modules, it creates corresponding entry in global system table i.e. table is locked. The system automatically releases the lock at the end of transaction. The LUW starts when a lock entry is created in the system table and ends when the lock is released.
    Creating Lock Objects
    Lock object is an aggregated dictionary object and can be defined by using the following steps:
    o From initial data dictionary screen, enter the name for the object, Click Lock object radiobutton and then click on Create. The system displays a dialog box for Maintain Lock Objects screen
    o Enter short text as usual and the name for primary table.
    -Save
    -Select Tables option
    From this screen you can:
    Select secondary tables, if any, linked by foreign key relationship.
    Fields for the lock objects. This option allows you to select fields for objects (R/3 system allows locking up to record level). Lock object argument are not selected by user but are imposed by the system and includes all the primary keys for the table.
    1) Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
    2) Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
    3) Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
    Also, last but not the least, locking the object is logical (locking with any enqueue ) .so, you have to use the lock object while trying to access from second program .

    The update failed - using a USB to microUSB lead (that Apple annoyingly don't include!), try to restore the AppleTV software to current version software using instructions here:

    Pay attention to differences in power connection depending on whether or not you have AppleTV2 or AppleTV 3.

    Hi, a too full hard drive can really mess things up.
    Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, , try to clear at least 10 GB of space & empty the trash, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

  • I want to return my ipod but the serial number faded away and i dont have the reciet and the screen is broken. what should i do?

    my screen is broken and i want another one. the serial number fadad away and i dont got the reciet. it did have warranty. what should i do?

    You won't be able to return it.
    Did you cause the screen to be broken?  Or are you saying that it failed under warranty?
    If it's still under warranty, and you didn't damage it, then they should replace it.  They can plug it in to get the SN and look it up.  It has a 1-year warranty.
    You can enter the SN here (if you can read it) and it will tell you if it's still covered:

  • I made a movie in iMovie then deleted the clips in it. I have reimported the clips in an event with the same name as previously and some clips in the movie are still saying source slip missing even though they are there. What can I do?

    I made a movie in iMovie then deleted the clips in it. I have reimported the clips in an event with the same name as previously and some clips in the movie are still saying source slip missing even though they are there. Some clips are fine in the movie, but most are just black and when I hover over them, it says source clip missing. How to I fix this? Thank You

    I did that too, then I did a migration assistant to a new Mac and ALL of my movies have Source Clip Missing now, even though the original clips are still in the iPhoto Videos.  I can stand to re edit one or two projects, but not ALL.
