Re: Spliting a cat5 cable? (Tivo Vs Cat5)

[steve.cooper@xxxxxxx]

You can't use two networked devices on the same cable by just
connecting
them in parallel.  The way the splitters work is by utilising the fact
that
only 4 of the 8 cables are used.

258B
RJ45 pins    
Color          Signal
1         white/orange  
TX+
2        
orange         TX-
3        
white/green    RX+
4        
blue      Unused
5        
white/blue     Unused
6        
green          RX-
7        
white/brown    Unused
8        
brown          Unused

So the cheap way is to do it is to wire up the orange pair and green
pair
into one plug.  Then in the next plug switch orange for green and
brown for
blue and you have two network points.  For the cost of a couple of
extra
sockets.  As long as you do the same both ends and mark them up so
you
remember that pins 4,5,7 and 8 are dead your laughing.

The cost saving should help you pay for the sub :-)

SWMBO has sanctioned the purchase of a Tivo (thought to be fair I did
gloss over the subs a bit : And the tivonet card. And the extra
harddrive).

However, this however leads me to the now common problem of "not
enough cat5 for the new box".

Due to many problems there is no way I can run more to that corner of
the lounge. So I was browsing Netshops site and came across these
splitter things that plug into the sockets either end of a cable run
and create two sockets each end. However, these things are expensive
and look untidy.

So,
1) do these things really work (for 100megabit)?
2) Can I just plug an extra cat5 module into the existing wall socket
and rewire the cable into both modules, and then rewire the cable at
the patch panel to use two neighbouring sockets? (instead of using
the splitter).
3) If I can do this, does anyone have a suitable wiring diagram?

TIA.
