Just thought I'd let you know that we successfully tested shooting tethered with the H3D31 and a firewire repeater giving us 25 meters (about 75 feet). Camera worked perfectly!
Setup was standard FW800>FW400(4.5Metre)_DVRepeater_FW400>FW400(20Metre)_Laptop.
Here's the (unpowered) repeater:

Nick,
Sounds great, it looks like the repeater doesn't require any power. Is that right? Do you think it would work with an ixpress back and an image bank?
Alan Housel
Hi Alan
Yes it's unpowered. Haven't had a chance to try it with the 384 yet, will give it a go and report back.
Cheers
Nick-T
Hi Nick
It was on a G5, Mac pro, Mac book pro ?
FW plug on the front or back ?
regards
Olivier
Hi Olivier,
Nick might not be able to answer for a day or two so I will on his behalf (hope you don't mind Nick?)
It was on a MacBook pro which was plugged into the mains, not that that should make a difference.
Hope that's helpful.
Cheers
Matt
This setup worked for me:
FW-142 Firewire Repeater 800
CAB-FW-33B Firewire 800 33ft Cable
CAB-FW-15B Firewire 800 15ft. Cable

http://www.gefen.com/kvm/dcable.jsp?prod_id=5860
The gefen web site states that you can go up to 250' with a repeater between each 33' cable.

Anyone tested this set up with a PC laptop - like DELL XPS? Without a repeater, I can´t get a 5 meter firewire cable to work tethered.

I think you might need a powered repeater, I think many of the PCs have un-powered firewire ports. PC Guys care to chime in?
Nick-T
Desktop PCs seem to have powered firewire ports (400&800) but I have not yet seen a PC laptop with a powered port except perhaps the Lenovo W700 that seems like it might have a 800 port even though the spec says 1394a.
Read this thread a few days ago and decided to order the Gefen cables and repeater to try it. Running off a MacBook pro 17" (latest model with only FW800 port). I can capture 4-5 shots before the camera loses communication with the computer and I have to reboot. Very frustrating. This happens with both an H3D-39 and H3DII-39. :(

Probably information that would have been useful 5 days ago, but I have to say we have had very little luck with Geffen cables and repeaters in Denmark.
Is the repeater made by Geffen too? If so, this simply didn't work for us.
However, the repeater Nick shows we have also used successfully.
Are you talking about the Datavideo VP - 314?
No, The Granite Digital one.
Has anyone tried this..

Sounds too good to be true, and probably is, but for a tenner it's worth a shot..
Otherwise the Granite - http://www.granitedigital.com/3port1394-a400repeaterhub.aspx is the one to go for..?

After reading your thread, I couldn´t resist performing some further tests with cables and repeaters that I have had lying around for quite some time. With a Chronus Express Card Firewire A+B (which, I power up with a USB connection), I finally got it to work with my laptop - Dell XPS M1210 using 1394A 6 pin contacts. Could even connect a 4.5 meters active cable. Still a bit before I reach your 25 meters, but almost half way, ha, ha. Will now get another 4,5 meters cable and see if that will work out too.
Cheers
Mats

I wish there were reviews on it. Too cheap to be true. I wonder if has any wires inside for this price :)
It looks like Lindy do one that's very similar if not identical for £25...

Has anyone had any experience with them? Are they sold in US or Canada?
I've found one like this, but for $68 :)

And this one has reviews:

Might be worth trying... But I still doubt it will work with a Hasselblad.

I've ordered one so will let you know how it goes.

Re: the £15 firewire extension cable - http://www.kenable.co.uk/product_info.php?referer=froogle&products_id=1002
Much to my surprise, it works. I haven't given it a full day in the studio yet, but it seems to handle connect/disconnect and bursts of shots with no problem.
The part with the firewire socket is a bit flimsy - if you stood on it it would break. It's a pity that that part's not a bit more robust otherwise it would be perfect. I'm sure you could get some kind of a box to put around it though, or just tape it up somewhere off from the floor.
Inside it has a little circuit board with some convincing looking bits and pieces so it's definitely an active rather than passive device.
I've tried it with:
PC desktop - dell 9200. Not sure who the make of the firewire card is and there's nothing else plugged into the card (I've found that if I have disks plugged into it they disconnect when I plug in the camera even without the extension).
15" MBP (the old one) on battery and mains, again with nothing else plugged in to the FW (or USB actually).
The extension is FW400, so I'm using a 5m FW400->800 cable to connect to the extension. Not sure of the make but I got it from the Pro Centre.

Hi Rob, thank you for the review! Glad to hear it works.
Alex
I have now successfully been able to connect my Dell XPS M1210 laptop using a PC-Exress card with 2 x 4.5 meters FW to the camera. The only general issue, I have even when just using a short FW cable, is to get the CF card recognized by Phocus. Normally, Phocus finds the camera immediatelly without thinking in what sequence you have to connect cables and turn on camera/load Phocus. But to recognize the CF, it is much harder.
To get it work last time, I had Phocus up running, camera on and then finally connect the FW to the camera and immediately the CF was there! Anybody else having similar problems with Mac and/or PC?
