Need to hook up 1 ethernet cable to PS3 and HD Tivo. How can I do this with out running anouther line? My home theater is upstairs away from my router. I have already run 1 ethernet cable to the PS3 for online gaming but noe have an HD Tivo that requires an ethernet cable for netfix. How can I split the one ethernet into 2 to avoid running another ethernet cable?

errr... sorry, but what has a question about ethernet cabling to do with an AVR microcontroller???

Einstein was right: "Two things are unlimited: the universe and the human stupidity. But i'm not quite sure about the former..."

Buy a cheap switch

IIRC, unless it's a gigabit link ethernet only uses two of the four pairs. You can get splitters that break each pair of pairs out to two separate jacks, sort of like an analog phone line splitter. One at each end will allow you to put two 100Mb links down one Cat5 run. But a cheap switch would work, too.

Actually, I see no need to discriminate other switches. Medium priced and really expensive ones will also do. :wink:

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

You could also use a, cheaper than cheap switch, hub. It will literally split the cable into two, or more. Many devices can use a single cable theoretically, but the more devices, the more likely data frame collisions will occur. (Both trying to transmit at once) This won't do much other than slow the link down and cause lag.

Are hubs still being used in new deployments at this age ?
Just checked my local computer price database, almost no hubs listed, however the cheapest switch is 13$ for 5ports 100mbit

I don't think you can even buy a hub anymore...maybe on ebay? Shipping probably makes it not worthwhile.

As others have suggested, if you've got yourself an RJ45 crimper, you can safely make one ethernet cable into two. I've seen this done on a number of projects, from simply home stuff to multi-million dollar research projects. Unfortunately, RJ45 crimpers are probably more expensive than just buying a cheap switch and some cheap cables.

If you don't have an RJ45 crimper, just buy a cheap (or expensive!) switch and some short Cat5 cables and call it good.

Good place for cheap Cat5 (or any) cabling is monoprice.com, at least if you're in the US.
