PLL Mode wiring on Romeo all in One Controller


I don't understand how to do the jumper setting and the wiring for PLL motor control on the Romeo All in One controller.


Do I realy need to cross wire the Pins or what does the x on the Jumpers mean? (this would then not be possible with jumpers, only with cables?)

Where do I connect the four signal cables of the two encoders?

If someone could help me here, I would be realy glad.

Thanks Robert
