# Overview

The Network Hub provides the essential function of bridging various networks so the devices can all talk together. Typically these devices and networks include an ROV tether network, a PC, and an Omnitrack, and possibly other items such as a Wi-Fi radio or second PC controlling payloads via Ethernet. 

The Network Hub can be powered directly from a PC via the USB-C port; from a battery bank (such as an iPhone external battery) via the USB-C port; or from a 2.1mm DC barrel input connected to a battery or wall wart. The Network Hub includes an internal Fathom-type interface for a BlueROV tether, a POE-enabled Binder 700 connector for a tethered Omnitrack, a USB-C connector for PC connectivity, and two Ethernet RJ-45 ports that can optionally be set to supply 24V passive POE.
