-**Note:** {{:files:data_0.png?nolink&15|}}1W, sometimes also DATA_0, is the main data wire. That said, if you connect a cable sensor with only a single data wire to the RJ45 connector, always connect it to pin 6 (eg. {{:files:data_0.png?nolink&15|}}1W pin). The {{:files:data_1.png?nolink&15|}}1W contact, sometimes also DATA_1, is a supplemental contact of Unipi sensors designed for a maximum possible bus serialization and serves for connecting the next sensor on the bus. The Unipi 1-Wire hub can serve as an example of the double-data wire principle. If you use a non-Unipi cable sensor with only a single data wire, the above-mentioned serialization with Unipi 1-Wire hub is not possible. You can, however, connect the sensor to the end of the bus (eg. as the last sensor in the hub).

 Connection to RJ45-connector network cable is useful for star-shaped network topologies created from 1-Wire hubs. You can also use it to connect the sensor to Unipi 1.1 extension board, or to the older variants of Unipi Neuron controllers.
-All these sensors can be also connected to the [[https://www.unipi.technology/unipi-extension-xg18-p331|Unipi Extension xG18 module]]. Coloured connection scheme on the picture corresponds to the T568B connection.
+All sensors with the DS18b20 chip and parasite power support can also be connected to the [[https://www.unipi.technology/unipi-extension-xg18-p331|Unipi Extension xG18 module]] with a minor wiring modification. Coloured connection scheme on the picture corresponds to the T568B connection.
