Interconnects
Two kinds of connectors are used on the PowerBox, 2.1mm DC Jacks, and 3.5mm 4-pole A/V jacks.
Power
On the Power side, In1 and In2 are the two redundant power inputs. These are typically fed from a 3s
Lipo, or equivalent.
Each input is fed via a low drop Schottkey diode, to the main power rail. This allows two power sources
to be connected simultaneously without any risk of damage. The PowerBox will draw from the power
source with the highest voltage.
Out1,2,3,4 are filtered power outputs, which may be used to drive other Ground Station equipment,
such as LCD Monitors, Antenna Trackers, etc.
Audio/Video
The connector marked A/V In should be connected to the output of your FPV A/V receiver. If an
ImmersionRC receiver is used, which has a matching 4-pole A/V connector, then a simple 4-pole -> 4-
pole cable may be used, eliminating bulky phono connectors.
If a non-ImmersionRC receiver is used, an adapter cable is available, interfacing between 3 phono
connectors (Composite Video/Audio Right/Audio Left) and the 4-pin standard connector.
Each of the video outputs are buffered, which allows up to 4 devices to be connected.
In a typical installation, an antenna tracker will be connected to one output, a recording device to
another, the pilot’s video goggles to another, and a guest’s set of goggles to the last output.
PowerBoxes may be chained to add an additional hree outputs if required.
