I'm using a FTDI chip to do the USB, but it allows me to do remote programming as well as communication. > Ethernet would be isolated but I don't know what's out there on the > market to isolate USB. There's probably a simple radio link for the UART too. If I knew it could get out of the metal box and across the house, I'd take the time to figure it out. It would save me having to put computers near each box to take measurements, too. But I know how the USB circuit works, and it'll be good enough for my purposes. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
