Yes, as i said before, i tested this DS9503. Hmm, what alternative adapter? Can you give link on ebay or aliexpress? And what does that mean "won't be quite as fast"? 1-wire bus speed? Thanks! ps. Can you give a bus voltage from DS9490R ? In my case it ~ 1 Volt (3 and 4 pin), but AFAIK sensors on parasite power needs 3-5V... -- View this message in context: http://owfs-developers.1086194.n5.nabble.com/DS9490R-1-wire-bus-short-circuit-tp10564p10570.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.
