RJ11 Wiring scheme

[Thiery]

Hi,

I have to make some extension cables inside my control cabinet for connecting the 1wire temp sensor.
Do you have the wiring diagram on the connector side?

Wire gauge sizes for SSR and RJ12

For an RJ11 connector (4 pin): 1 = not connected (12V) 2 = 5V 3 = GND 4 = OneWire data [image] The full pinout for an RJ12 connector (6 pins): 1 = RS485-A 2 = 12V 3 = 5V 4 = GND 5 = OneWire data 6 = RS485-B This is the pinout on the Spark side and on an expansion board side. So you want both plugs to look identical when you hold them next to each other. If pin 1 is yellow on one side, pin one should be yellow on the other side.
