Powering DC-In

The Network Hub is designed to be powered from a USB-C port on a laptop computer, for the basic load of ROV tether interface plus Omnitrack. The USB-C port must meet the USB-C specification to supply nominally 3A at 5V (not all USB-C meet the USB-C specification). If additional PoE loads are added you may need to use an alternative power source.

You can instead supply power to the Network Hub via its DC-In jack. This is a standard 2.1mm barrel jack with +V on the center pin.

If power is supplied via DC-In, then the USB-C port will draw only a miniscule amount of power from the PC. This should increase the PC battery life.

Typical alternative power sources for DC in are:

• 12V, 1 amp "wall wart" AC to DC power supply with 2.1mm barrel connection. These are widely available all over the world. This is one example.

• Standard 14.8V 4S lithium-ion battery pack with XT60 or XT90 connectors, using a XT60- or XT90-to-2.1mm Barrel adapter. We recommend lithium-ion (Li-Ion) instead of lithium-polymer (LiPo) because the power drain profile is better suited to lithium-ion battery chemistry. This is one example.

• DC in voltage must be between 10 volts and 18 volts.
