Need help converting RJ45 for Philips P2812-043

[Sixx93]

Hello everybody, I recently bought this Philips P2812-043 (https://imgur.com/IGZ4P1V , https://imgur.com/72tmLpi) but I have no clue on how to convert its RJ45 connector (https://imgur.com/RkXY3dH).

I did some research and, from what I understood, every keyboard can have a different wiring for this plug.
I already have a Soarer's converter for my Model M (AT plug), could it be reused in any way (for example rewiring the RJ45 into an AT, maybe with some electronics between)?

As you can see I'm a bit clueless on how to proceed, I don't mind soldering or tinkering with electronics, I have some expertise in general, but basically 0 in this specific "geeky" field.

Thanks in advance for any suggestion

If you bought your converter cable from Orihalcon, he makes them with various sockets.

It is not terribly difficult or expensive to make something like this if you can use basic hand tools, but the question is whether Soarer's firmware works with your particular keyboard. Soarer wrote his magnum opus to include IBM terminals, but, for example, WYSE gear needs a different protocol.
