Hi All

I bought a fire wire card and cable for about £25 the other week and when I
connect my camera to me computer the connection is intermediate. When, for
instance the light to my room is turned on the connection drops out or if
there is other electrical noise then the connection drops out.

does this sound like the cable is not shielded? Should it be shielded?

Thanks

Mine is shielded, and I think it should be. Maybe it has something to do
with the power supply in the computer?

I've never ever seen that. Where can you get shielded telephone cable?

Most often problems are caused by the routing telephone distribution
cables near (and parallel to) mains leads. A friend signed up for a 1M
broadband account but when the line was tested BT told the ISP that the
line was too noisy. A guy two doors away from my friend was able to get
the 1M connection (they are only about a half-mile from the exchange.

We had a look at his wiring and re-routed it, and he applied again for a
1M connection - and he got it.

Shielding, BTW, can make matters worse. If you have a look at BT's line
quality report (which goes to the ISP and not to you - but some ISPs
will identify what you line's failed on), one of the things is the
maximum capacity [1] of the line. Shielding increases that capacity and
can push it over the limit.

Florescent lamps can cause interference.

[1] Capacity in this context is not bandwidth but coulombs (farads).

That would be my guess. What's the wattage of the PSU and what cards, drives,
etc are connected?

Not quite Tony...

A Coulomb is an Amp-second and is a measure of charge.
One Farad is one Coulomb per Volt and is a measure of capacitance.

ROFL...

Some people would go around the hedgerows of the country so that they
could nit-pick off every hedgehog they could find :-)

In case it escaped you, I was *simply* [1] making the distinction that
"capacity" in this context was not that commonly associated with
bandwidth.

[1] "Simply" means that I wasn't on an ego-trip explaining
electrical theory, but putting the word "capacity" in
context.

Um, he was asking about Firewire...

There's something about this on http://www.camcord.info/tuning under
"PCI Bus Power Feed".

........ [no comment]......

A classic example of not reading the question or thread before embarking on
an ego trip of irrelevant knowledge, but then Tony never goes on ego
trips...... Ho, Hmm, is that a flying pig over head ?!

Do you mean intermittant?
Sounds like a dry join in the cable, picking up mains hum. but I have to say
it does sound a bit strange.
