74.2	11	The LSS Power Hub provides a simple solution to supply power to and communicate with the smart servos. It is also a useful tool to split the LSS bus from one servo to two or three while allowing these servos to be powered separately. The Power Hub can be mounted directly to the servos.

With the Vin jumper removed, the connector marked with an asterisk * is decoupled from the other three servos (blue and red no longer share Vin), allowing them to be powered separately from the barrel connector or other source.
