WAS Deutz agrotron New/MK4

Has anyone already tried using the WAS present on some deutz models from the agrotron NEW/MK4 generation (180.7 and 215 in my case)? In its real case it is used for the AMS.
I have nog yet tested the type of signal, but was wondering if anyone else has?
I also noticed there a rotative angle sensor in the steering collumn above the orbitrol. does anyone know what this is used for?

Update: The signal comming from the buit in WAS works but is of terrible quality. It has large hysteresis and has much noise and large jumps in it.
