Subject: Econet over UTP ?

I had a similar idea for Econet wiring, using boxes with dual RJ45 face plates
chained together with Cat 5 cable, but using DIN leads cut in half and RJ45
connectors crimped onto the ends, which is much easier than soldering DIN
plugs onto Ethernet cable.

I had it working in a test rig set up in a friend's garage in Hull in February
2007 (what a way to spend a weekend!) but the only thing I didn't get
round to resolving was termination.  However I think it would be a fairly
straightforward matter to get a little 2-inch length of Cat 5 cable with
an RJ45 connector crimped on one end and the terminating resistors
soldered onto the other end of the cable and then sealed in a little
box or some other housing, so that these terminators could be plugged in
as required like the SJ Research ones.

That way, all the items required can be made up using readily available
kit without the need to produce any new PCBs or custom boxes.

Best wishes,


Ian

Sorry if I'm missing the point, but why not go with RJ45 sockets and
UTP?  And use Ethernet drop leads cut in half with a DIN soldered on one
end for the drop cable?

Cheap as chips and easy to extend.
