Reply To: EZIO8SA and 1-wire confusion

Well all I have are RJ-11 plugs, so I don’t have access to the 5V+ pin. I’m a bit confused, if you need to run a 4.7K resistor from the 5V+, wouldn’t it be simpler to just connect the VDD directly to the 5V+ and not need the 4.7k pull up resistor, or would I still need to connect a 4.7k resistor between the 5V+ and the DQ pin even though it is being actively powered???

It looks like I’m going to have to invest in some RJ-12 plugs, although I swear I recall the EZIO8SA docs say that RJ-11 plugs can be used to connect 1-wire devices.

I wish these guys would write more detailed instructions for their products….
