For example, if the backup power is connected to the BEC of your ESC (via your receiver), and that is supplying
5.0V, the Vector will use the PSU power unless the PSU voltage drops below 4.5V. Likewise, if your BEC is
providing 6.0V to the backup power port, the backup power port will always be powering the Vector unless the
BEC output fails.
Note that the backup power input will NOT power your camera or video transmitter. Only the Vector
and accessories connected to the “Bus” port will be powered.
3.2 Vector GPS/Mag and Current Sensor/PSU Connections
Connections to the Current Sensor/PSU (Deans
TM
version shown), the GPS/Mag, and the optional Pitot Airspeed
sensor are shown in the figure below.
The “Bus” connectors on the GPS/Mag
and Airspeed sensors are internally connected
together. Wiring order, or which of the two
connectors on each sensor is used, does not
matter.
In other words, you can plug into either “Bus”
connector, and if you “daisy-chain” the
Airspeed with the GPS/Mag, either unit can be
at the head of the chain.
Never connect the GPS/Mag or pitot
sensor to the Vector’s AUDIO
connection. Doing so will destroy the sensor!
