Hi,
Could anyone help me? I would like to connect several DS18S20 on one 1-wire net. I have a 1-wire USB connector (DS9490R) as the computer connection for the 1-wire net.
I have successfullt connected several parasite powered DS18S20 to the RJ11 connector of the USB Adaptor (Connected RJ11 PIN 3 to DQ(2) on DS18s20, and pin 4 to Vdd(3) and GND(1) on DS18s20). Works fine!
Now I want to supply +5v to the DS18s20 to make it non-parasitic powered. I tested to connect RJ11 pin 1 (Vdd) to pin 3 (Vdd) of the DS18s20, but then I couldn't get the ds18s20 to work?
What did I do wrong? Do I need to do anything else to power the ds18s20 from the RJ11 connector?
