Alternatively, a system can adopt multiple power supply solutions. In this way,
STARGATE™ units can be powered separately from the STAR-Box™ network. See
par. 2.5.1 for jumper settings.
Power is supplied to the STAR-Box™ through the pins provided on the spring clamp
connector.

NOTE
Pin 11 is electrically connected to pins 3 and 8, just as pin 12 is
electrically connected to pins 4 and 9 to allow power propagation
throughout the entire network. Pin 13 is electrically connected to pins
5 and 10 to allow the Shield to protect all network branches.
The
Shield should be connected to earth ground in one point only.
The power supply must be between 9 and 30 Vdc only.
