Tethered 1Ds + 1Ds Mark II

Ed11
I own a basic p4 3.0 GHz PC 2 GB memory Window 2000 (lastest update)
I have use bought a new 1Ds mark II camera. And in connecting and disconnecting the camera sometimes C1 pro 3.71 sees the camera and most of the time it won't.
C1 than hangs completely and sometimes in completely hangs the entire OS system, which for a 2000 system is very rare. I much reboot the system complety. I have installed the latest TWain driver from Canon. But this won't help either.
Also I would have the possibility to connect my 1Ds and/or 1Ds II. But since the system hangs on just one camera, it's likely C1 will hang to.

    Verify the TWAIN driver (Version 5.5.0 is the latest)
    Also try it in the Canon software, do you have the same issue?

    From own experiance I can say that the TWAIN driver on Windows 2000 is not to stabile of a solution when TWAIN is a old Scanner protocol and not mad for high burst rate 16mp cameras.
    Where the WIA driver for Windows XP is har superior.

    You can only operate one camera at the time.

    Since your answer I tried several things. First the auto detect feature doesn't work correctly. This has nothing to do with 16mp IMO. Because no data of this size is being send. When you shut the camera off C1 doesn't detect that action. You'll have to manualy trying to connect a disconnected camera before it actualy sees no camera. After that switch the camera on and c1 sees the camera. But very unstable, sometimes no camera and I'll have to restart C1. I have no problems with the Canon software it works like it should, despite any speed issues you've mentioned. Looking at some posts on this board, I'll conclude that as for now it is not possible to get a stable connection with c1. Again no problems with canon software which uses the \"old fashioned\" TWAIN driver.

    edtepas,

    That would be a poor conclusion since there are many many Users successfully tethering their Canon cameras with Capture One.
    Yes, there are a few posts on the Forum and just a couple support cases regarding tether problems but they are not prevalent.
    May be a TWAIN driver is fine as you say, but it is interesting that one common denominator for those with tethering problems are using Windows 2000.

    Here is a suggestion by another User that resolved their connection problems.

    Actually, for our 1Ds cameras I did the opposite of the what the release notes said and turned Custom Function 02 to allow the camera to take pictures without a CF card and that's what worked. Our Mark II cameras worked before, no matter what setting they were on (provided firmware was updated).


    After you launch Capture One, the application will try and auto connect your camera to see if it is connected to the computer. When you switch on your camera and the LCD screen is lit, the camera is in a special mode which prevents the operating system from connecting to the camera. You must quickly cancel this mode by either:

    1. Quickly press the shutter half way down and release it again
    2. Turn off the LCD screen

    If Capture One does not auto connect your camera after this, reconnect manually via the “File | Reconnect camera†menu item.

    Phase One recommends that you first switch on your camera and make sure the LCD screen is turned off before you launch Capture One.


    On Windows 2000     you can experience that sometimes the operating system does not send a disconnect message to Capture One. This can happen if you turn off your camera or switch cable from one camera to another. Capture One will falsely think that the camera is still connected. If this happens you cannot reconnect your camera again and you will have to shut down the camera and application and launch Capture One before turning on your camera.

    Hope this helps you out.
    Please let us know anything that you learn that will help others with similar situations.

    Cheers,
    kc
