The transmit portion (uplink from vehicle to surface) of the 4 Port 10/100/1000 Mbps Ethernet Switch
takes in 4 standard 10/100/1000Mbps Ethernet signals via RJ-45 connectors and processes the received
signals through an onboard Ethernet switch. If needed, packets are routed to the fiber optic transmitter for
delivery to the switch at the opposite end of the link. The receive portion of the 4 Port 10/100/1000 Mbps
Ethernet Switch accepts the optical signal from the remote end of the link, and recovers any Ethernet
packets present. Those packets are then routed, via the onboard Ethernet switch, to the appropriate RJ-45
connector on the board.
The 4 Port 10/100/1000 Mbps Ethernet Switch requires a +5VDC power source provided through the 2-
pin Phoenix connector at J5. The boards have an on-board 5V to 3.3V, 2.5V and 1.2V converters to
provide power for the components that use those supply voltage.
