FireWire Error msg when shooting thetered

Olivier111
Hello

I have a MacBook Pro 2.16Ghz with 2 GB of RAM and the 100Mb 7400 RPM HDD.

I have the latest C1Pro and I very often get the folloing error MSG.

Failed to prepare camera for capture. The command could not be completed due to a FireWire related error: 000002D6.

When I press OK, I get the following error: An system error occured: -7106

I shoot with a P45 on a H1 hassleblad

My firewire cable is brand new.

Anyone know what is going on?

Thanks for your help.

    Hello

    I would change firewire cable to an new one, not over 15\", make sure that the P45 is set to use battery power (not to Auto or FireWire)
    Error 000002D6. is a Apple error msg, -7106 is connection related Capture One error msg.

    First things first is to hook it up to another computer also you should contact John Paul at Vistek who is the local dealer in Quebec.
    Otherwise you are also welcome to make a support case at http://support.phaseone.com, both options will assure quicker replies.

    Thanks for the reply, I know John Paul quite well... He installed the latest firmware last friday on the P45. I'll contact him and we'll probably meet next week...

    Thanks

    I've had this issue with a P30. The photographer had supplied me with a cable with a firewire repeater. Once I removed the repeater and used a stock 15' foot cord all was well. Unfortunately it seems the newer backs are less cable of using the 30' distance.

    I am facing exactly the same problem. I'm using a P45 on a H2 camera. Shooting tethered on a Macbook pro 2.0 GHz with 2 Gb ram gives the same trouble you mentioned. I have tried two different lengths of FW cable (15 ft and 30 ft, original
    Phase One quality) but nothing helps. I have switched to a G4 powerbook which solved the problem but is very slow compared to the Pro book. Connection to the G5 Power PC works perfect as well. It seems there might be a problem with the Macbook Pro at high temperatures. Shooting in a hot studio (30 .C or more) gives trouble, while shooting a location job at 10 .C worked fine, even with the 30 ft. cable. Can this be possible? Anyone?

    the problem comes from the fact that Apples laptops and Imacs have underpowered FW ports.

    The problem is solved by inserting a powered FW hub. (60$ can)

    Thanks, but howcome the G4 laptop gives no trouble at all. Besides, I am working with a laptop when shooting on location where there is no socket to power the FW hub. I am not sure if you mean an external hub or a modification on the exisiting FW port. Please let me know.

    Regards Roel.

    By inserting I meant placing a standard external powered FW hub

    the setup should be...

    LAPTOP-------FW HUB---------CAMERA

    And why you are not having any problem with the G4 laptop...

    Probably because that specific laptop generate enough power (you got a good one)

    the HUB can be a FW/USB2.

    Get a sturdy HUB... that little device will fall to the ground often...

    Doesn't that FW hub have to be powered (ie plugged into hot power) ???

    Kinda beats the whole purpose of using a laptop with a back.
    Might as well have the whole tower on location if you need to be plugged in.

    It sure is annoying.... The real solution would be that apple make a huge recall on all Powerbook, MacBook Pro, iMac (intel & PPC) and replace them with properlly powered FW and HS-USB ports...

    Not Gonna Happen...

    That leaves you with 2 choices...

    1- shoot thetered with the annoying FW error...
    2- use a powered FW hub

    Cheers.

    Hi roel nederveen

    We are currently investigating a problem that sounds like what you are experiencing.
    Phase One have discovered that the problem relates to the FireWire chip in the Intel Macs, which is not stable enough when getting warm. This causes transmission problems between the FireWire chip in the Intel Macs and the chip in the Phase One back.

    We are at the moment investigating if we can create a software or firmware solution, that eliminates this problem. This as we doesn’t expect Apple to do an exchange of all the Intel Macs sold.
    The problem does not appear when the back is connected to a Mac running the G processor range. A work around might therefore be to switch hardware platform to a Mac running the G processor range.

    As soon as we have a solution we will let you know.

    A work around that has a very Huge price tag. The only PPC worth buying (if shooting thetered) is the PowerMac G5....

    and not very usefull on a beach.

    But yes, it's a work around.

    Personally, for the time being i prefer using the powered FW hub (it's about $4040.00 cheaper than the G5 work around)

    cheers

    does it make any difference if you use a short (3-5m) FW cable with a macbook/pro?

    No... It does not.

    This problem doesn't really concern me as I don't shoot with a firewire back, but a possible solution for this problem just popped into my head: The problem is that the firewire ports on the macbook are not working properly, so has anyone tried using an ExpressCard/34 Firewire port expansion card? That would solve the issue of having to plug in a FW Hub and I would assume the card would be more stable than the stock macbook one's. B&H has an SIIG one that is $80. If someone has already tried this please ignore this post.

    Thanks for the tip Oliver, and sorry for my late response. I've purchased a powered FW hub and the connection is working almost flawless ever since.
    On one occasion I had to restart the Mac. Guess what; a very HOT Mac at that time, so temperature is likely to be an issue here as well.

    Let's hope a firmware update can minimize or solve the problem in the future.

    Regards, Roel.

    I'm glad it did help and Yes the temperature is a problem.

    Cheers
