RE: Extending USB Connections
>It was
Mark
who suggested KUT5 :-)
yeah well he does like to stir
:-)
I'll report back when I've had time to play with
USB,
probably be January though, SWMBO will kill me if I don't finish decorating
the
lounge before Christmas!!
Daniel
It
was Mark who suggested KUT5 :-)
I
will stick to the AV stuff for now. Let us know how you get on with
modifying
cables. Like I said, I dont have any USB kit to experiment with
anyway.
Keith
Just found this
Looks like someone have beaten you to making KUT5
:-)
I'll try messing around with some USB cabling at
some point over Christmas.
Cheers
Dan
Instead of spending more money on a camera, why not buy a couple of
USB connectors and make a lead.
PC USB_Plug (A&B) RJ45 ---------CAT5---------RJ45(A&B
+ Local 5V input)USB_Socket <Webcam
Keith
PS. Dont blame me if it doesnt work !
Umm.. thanks for this Keith
I might look at buying a cheap (£20) camera and
pulling it to bits then..
Dan
I would be tempted to try USB over a longer
distance.
I believe the main limitation is in the pair of wires feeding
the power. USB has 4 wires +5v, 0v, A & B. A and B are the data
pair, as long as you used a local power supply at the distant end it
might work OK. As I understand it, the actual DATA is carried as a
balanced RS485 type signal so should be good for quite a long distance
over CAT5.
Of course, I could be talking B******* as I have never played
with USB.
I cant test this theory as I dont own any USB
kit.
Keith
Excuse the blonde question :-)
but why is their such a limitation on the
length of cable for USB? - do they use very low voltages for their
signalling, and as such this would deteriorate over any distance -
say 15 metres?
<Whinge mode>
It just seems such a waste, that I can buy
a reasonable colour web cam for under £50 and I could then have more
than one connected to my pc, that they would all have to be within a
few metres of node Zero!!

out of the box!!)

that was what USB / Ethernet adaptors did!
Most don't , but
I'm sure there's some that do ... somewhere ...

yeah, gotcha.

I'm sure I've seen them around,
but I've no idea where. Perhaps someone
else
has?
