Its a bit confusing. I went through all this last summer, so its not fresh in my head. There’s a number of blogs that can get you to a target setup. I suspect you want simple. There’s a long hand version that people pioneered first, and helped each other. This is the main blog I used. If you really really want to crawl before you walk, scroll down to the forum-like section at start at the beginning. Its a painful read as a lot of failings. Or, go to the bottom and work backwards to sections where people got it working.
In the main section, the author describes pin-outs for special ethernet cables and devices. He had some conflicting pictures that he finally updated to make everything be in sync with what he was saying. I don’t want to post those diagrams here, so I will refer you to his write-up.
Here’s the hardware I used to rid my setup of the SL router.
Tycon Systems POE-INJ-1000-WT High PoE 4 Pair Injector
48V 3A Power Supply | AC to DC 48V 144W Power Adapter
It took me several tries to get a 3A P.S. that would power the Tycon converter. The right amperage and wattage is important. I recommend these.
You still need the blog to figure out how to make the Special Pinout Ethernet Cables, because they must cross over the signal.
I said there was a long hand version and there’s also a short hand version.
Someone took the hard work everyone did and made it easy.
They had two devices made in China that you can now get on Amazon and shortcut all this work.
YAOSHENG 150W GigE Passive PoE Injector
YAOSHENG Rectangular Dishy Cable Adapter to RJ45
My setup was already working, but “looked” clumsy, so I ordered and received the Cable Adapter, and swapped it out to test it on mine. There was a few people that didn’t believe it would work, so for $38, I decided to test it. It worked fine. Easier than making your own.
I did not get the YAOSHENG PoE Injector, since I was already using the Tycon and power supply. But I have heard it works. So, for less than $125 you can get nearly all the hardware you need.
And recently, I found this Dishy V2 original plug (SPX) to RJ45 (T568B) adapter FIT For Internet Kit V2 POE
I don’t know yet if I will integrate it into my setup. I have not received it yet, but for $8, I could not pass it up. (Of course you know the SPX reference is the nickname everyone seems to be using for the goofy Starlink connector on the cable.) And by the way, Gen 3 doesn’t use this odd connector.
Consider this. Most people that morphed their system to get rid of the router, wanted to reduce the hardware (heat). The Starlink router puts out a lot of heat, and therefore is power hungry. AND many that started this, were mounting it in a 12V powered vehicle, RV, camper or such. So, they needed to boost their power from 12V (vehicle) to 48V (Dishy). That’s why you see people going 12V to 48V, but I was going 120V to 48V. Some people used a 12V-48V buck converter up, not 120V-48V down.
You should know, when you remove the Starlink router from you feed, you lose some of the functionality in the Starlink app. No longer check signal strength, (speed, yes, strengthen, no.). Can’t do that "walk around checking your perimeter. You don’t see it come on-line, until it comes online. The app doesn’t know what to do, how to react to a non-Starlink router, so can’t tell you what it could with the Starlink router. But its still useful (needed). Remember - think of the things the app gets from Dishy, vice what it would get from the router, and it makes more sense.
Too much info?
