anybody here made their own firewire cables?

[safe as milk]

hi
i've been searching around for some 15m, 4pin/4pin firewire/audiowire
cables, so i can put a noisey mac in a machine cupboard.

does anybody here have any experience in making these
or if anyone knows of a supplier that has them?
i'd be extremely greatfull,
one uk supplier has been promising me some for over 6 months now,
must be at least 15m length.

thankyou very much

There's an abolute length limit... and it's LESS than 15 meters.

Firewire is a complete bee-hatch. You can 'break' firewire cables just by flexing them, and taking them out of their characteristic impedance range.

I say just buy them. -I refuse to try and make one. I tried using Neutrik couplers and couldn't overcome the length/reliability limit.

Just a sad fact.

hi
thankyou for that, im all up for buying them
but i'm really struggling to find someone with that length
available,
according to motu i can run up to 18m but i cant use
repeaters(already wasted money on trying them)

so anyone know of a good supplier?

thanks,
so near and yet so far, i've got 10m but it's too short,
got to be 15m, and 4pin/4pin, which is why i've come unstuck

firewire repeater?

edit: just read the 4 pin criteria - you can get adaptors too eg.

hi
yeah repeaters, i thought i'd mentioned that they don't work,sorry

passive or active, i've tried both but to no avail.
so i need a plain 4pin to 4pin 15m cable, please someone...anyone!
thanks

I'm curious now as to what it is that you're connecting to what :?

 

[orange]

FWIW lindy do a 10m 4pin to 4pin also. But you can use 4pin to 6pin adapters, they are passive.

I thought all the motu stuff was 6 pin ?

you can get 50ft in the US

bear in mind that the firewire spec states that 4.5m is maximum. I've had good results with 10m but never used anything over that.

hi,
thanks for asking,
it's not that wierd'a'thing really,
it's a firewire pci424 motu card, to a 24i/o external rack,
going to put the mac with the pci card in my machine cupboard
with the 2inch and 2track tape machines, as it's physically noisy.
the motu rack needs to stay with my outboard in the control room
though, hence the stupidly long lead.
already got leads for usb/screens(tested all working)
just missing this vital one.

right, sorry it's 6pin-6pin, thanks for pointing that out
cheers

cheers orange,
i'll order them from there, that's made my day,

thankyou very much :thumb:

 

[emtee]

Ah, the PCI 424 is not strictly firewire either - I think you can use longer cables with them than you can with normal firewire so you should be ok.

hi
yeah up to 60ft off a 424card,
thanks for your help guys

 

[SonsOfThunder]

Don't know about the 424 card, but the 324 is kinda picky about the kind of cable you use. I have good luck with the Belkin brand but I don't think they make one more than 5m.

That part number 70981 looks like a similar cable to the Belkin.

MOTU support told me that the kind/brand of cable did not matter...they were wrong!

HTH!

Have you got them/tried them yet - do they work - I've got a similar situation.

 

[safe as milk]

hi
i ordered them on the 7th, but i havn't seen nor heard
anything yet, i reckon on sometime this week.
i've used 10m with no problems before off a 424.
are you running the same card?
when they arrive, i'll post to confirm they work.

cheers
