25 Metre firewire!

[NickT]

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?

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

Hi Nick

It was on a G5, Mac pro, Mac book pro ?
FW plug on the front or back ?

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

This setup worked for me:

FW-142 Firewire Repeater 800
CAB-FW-33B Firewire 800 33ft Cable
CAB-FW-15B Firewire 800 15ft. Cable

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?

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?

[David Grover]

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.
