| The sensor features a 4-wire connection to improve the reliability of branched networks. However, it is possible to modify it for 3-wire connection by joining 1W (DATA) wires if needed. | The sensor features a 4-wire connection to improve the reliability of branched networks.

| It is necessary to follow the correct port order when connecting devices to the hub! Port 1 must be always used as an input port, the remaining ports must not be skipped; otherwise, any devices connected after the skipped port would be cut off from the 1-Wire bus. | It is necessary to follow the correct port order when connecting devices to the hub!

| It is possible to create a chain of multiple hubs if an extensive network of 1-Wire sensors or devices is needed. When interconnecting two hubs the topology stays the same - Port 1 serves as an input while the output is located on the last port in order. | It is possible to create a chain of multiple hubs if an extensive network of 1-Wire sensors or devices is needed.
