Later SpaceX released an official Ethernet adapter that brings up the port back.
Probably SpaceX has some usage stats that show most users use only WiFi.
The Starlink ethernet adapter has the Ethernet port, Dishy proprietary port, and Dishy proprietary connector.
It’s easy to open the plastic cover with a flat screwdriver. Not much in there:
The Double-sided board contains connectors and an Ethernet circuit.
So, this is just a Dishy Ethernet + PoE passthrough and AUX Ethernet transformer with a required minimal circuit.
This means that the router contains a 2-port switch.
The second port is used for the AUX Ethernet, but the Ethernet transformer is now in this adapter. It saves a few bucks and some space on the router board. But I don’t think this is good to move Ethernet magnetics so far away from the PHY IC.
Here is a schematic of the adapter:
Thicker wires are used for the Dishy Ethernet+PoE passthrough.
Thinner wires connect the AUX Ethernet circuit.
The Starlink proprietary connector it’s a 20-pin interface that looks like a mini-HDMI but is not the same.
There is an
SPX marking on the connector, so I guess it’s custom-made for SpaceX.
Here is a pinout of the socket (router and adapter inputs):
It would be nice to get the new router and see if it’s possible to integrate this circuit inside the router.
UPDATES, June 14
SPX proprietary connector it’s a USB-C connector in an unusual shape. You can bend the USB-C to fit the SpaceX one.
The terminal use 802.3bt PoE that is carried over all eight lines: 1-2, 3-4, 5-6, 7-8, 13, 14, 15, 16.
You can find the custom PoE injector schematic in the comments below.
I managed to get the new router, so there will be some updates.
