Hmmmmm, connecting PS2 cables with RJ45 connectors? :rolleyes:
In the link you provided the author speaks about using modular connectors. But he/she never did actually use modular connectors. Both the pictures and description shows the wires being soldered together. So he/she was speaking about an alternative method if you like using modular connectors.
But let’s poke at this a bit. You would start with the female PS2 cable end and attach a male modular connector. Then attach a male modular connector to the male end of the PS2 cable. And then what? Plug the two modular connectors together with a coupler? Something like this?
Sorry, picture got lost.
I challenge you to show us a finished/tested-working cable using modular connectors!
