I've been searching through the forum for means of connecting a PIC based project (the 4ch thermostat posted in the code section) via Ethernet and an embedded webserver. I came across this this thread which show several devices costing around £30 - £40.

One shows a diagram (see below) that seems to suggest you simply connect the two lines (rx & tx) from the PIC to the device and then RJ45 from it to the router and then enter the default IP / MAC address (much the same as accessing a router or adsl modem) to set up the comms and upload the "web page" for the device / data you want to display.



Is it that simple, or have I missed something ?
