Connection of BNC (Coaxial) Connector to Ethernet

A BNC is a single conductor RJ 45 has several conductors which carry signals.
You can't just join the two without a modem to convert the incoming signal.
E.G.
In my home we have broadband coming in on coax, it goes into a modem, then a router which is connected (by wires, not wirless) to 4 RJ45 sockets in the various rooms.

Yes, they can!

welcoming you.

Coax ethernet, or 10Base-2 thinnet, cannot be directly connected to 10Base-T or 100Base-T ethernet, with its two twisted-pair wire channels. There are converters, such as the Unicom UTP20038T, pictured, offered by L-com for $79.

The 10Base-T side is best used plugged into an ethernet switch, which would learn the IP addresses of the devices on the slow 10Mbps side of the network, and route only appropriately-addressed packets that way. The switch also buffers the fast-arriving data packets and sends them sloooowwly over your 10Mbps 10Base-2 coax network.

Hi! I love your book! "The Art of Electronics". Great book.

Thank you very much. We're nearly done with the 3rd edition, a massive rewrite, lots of amazing new stuff (well, amazing to us anyway, as we learned about it). But there's a few months of work remaining and we're still soliciting ideas for what our readers, you, would like to see in the new edition.

The MOSFET, advanced MOSFET, POWER, advanced POWER, advanced OPAMP, Noise, PRECISION, and the advanced PROPERTIES of COMPONENTs chapters are all still wide open. Sheesh, looks like more than a few months of work remaining!

You mention the pending release of third edition which I forgot to ask about.

Thanks for the update. I didn't realize that ideas were being solicited. That is really cool! Hopefully, folks here on CR4 will chime in with their thoughts.

I'm not sure the forum readers recognized you as the co-author, but since you used a real picture as the Avatar (with a real name), I picked up on this right away.

Wiki mentions that the 3rd edition is overdue and that some components from the 2nd are obsolete. I use the 2nd to mentor ARRL on-line students (Digital and Analog Electronics) and find it quite useful even in its present form (as the very basic principals are being taught and these haven't changed dramatically). I would certainly be interested in the 3rd edition.

Perhaps you could start a new thread here or a post a blog entry to gain wider notice and get some ideas.

I'm glad I didn't post off-topic as some CR4 members tend to ignore such posts.

Good luck with the book!
