Tether Cables for P backs

Postby sinar » Fri Oct 19, 2018 9:55 pm

I keep an old P25+ back as a spare, but my macs have all been newly updated. Does anyone know of any cables that are FW400 to Thunderbolt or USB C without attaching numerous adapters. Would be really sweet if Phase One could sell them, as it's still a good workhorse of a camera.

"A combination of Apple's FireWire to Thunderbolt adapter plus a Thunderbolt 2 to Thunderbolt 3 (USB-C) adapter will NOT work properly (even when Phase One backs are forced to use battery power)."


That is not correct. I've done this on mulitple occasions as described here:

You need to update the PhaseOne knowledge base, Ulf. I've given all the details to PhaseOne support but it looks like they didn't test it...

Hi


We have done extensive testing on this.
When originally introduced it did not work at all.
With later updates of Mac OS / Mac Book Pro EFI updates we have found some instances where it did work and some where it failed.

As such we can simply not recommend anyone to use this.

Ah, well I can only speak for those photographers that use Mac and use a Thunderbolt 3 - Thunderbolt 2 Adapter + Apple Thunderbolt 2 - FireWire adapter and that works for them - I didn't know there were other issues. In that case you're correct to not recommend it!

But for Windows 10 it works definitely, I've tested this on 3 Laptops and 2 Desktops and there are 0 issues (when following the steps I listed) - so perhaps it would be a good idea to amend that at least...

Hi
Nice, good to know. Could you let me know what generation you have tested? (What camera back)
It is probably not a P series but one of the P+ series I would guess...

So, my understanding is that for a P+ back I should use an OWC Thunderbolt 2 dock with my MBP 2015 that is Thunderbolt 2, with Apples Thunderbolt adapter plus the FW 400 to 800 cable.
Will this also for my iQ back on a Thndblt 3 iMac?
The average customer review for the THNDRBLT 2 is ONE star....time to dump the P back

Hi
OWC Thunderbolt 2 for any Thunderbolt 2 Mac
OWC Thunderbolt 3 for any Thunderbolt 3/USB-C Mac

Both will work with any Firewire based Phase One product.
