i bought new DS9490R and it works with existing 1-wire network. I use only 3 and 4 pin of DS9490R (made rj11 with only this pins). Power is external 12V and transform to 5V on each client device. I will try to change DS9503 later ... -- View this message in context: http://owfs-developers.1086194.n5.nabble.com/DS9490R-1-wire-bus-short-circuit-tp10564p10582.html Sent from the OWFS Developers mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
