NOTE: If using a 12 volt power supply it is recommended that the cable length from the power supply to the Echo sensor be no more than 50 ft (15.24 m) in length.
The connector also contains an element to which the ground wire is attached. The other end of the cable is what needs to be connected to power, communications, and ground in the breakout box. Cable pinout is a combination of standard Ethernet and custom. The green and orange pair are wired like standard Ethernet for 100Mbits per second data transfer. The wiring and pinouts for the connector are shown in the figure below.
