To connect the Moxa with my apus I had to customize the cables I got from aliexpress.
Till now I never had to create my custom serial console cable, so to me this was a new experience.
Finding the combination
I first had to find out the correct combination of cables since it did not work with these cables right away so I put a breadboard in between the cables. To connect the wires to the breadboard I did crimp connectors to them.
