5.7 RS-422 Interface
The RS-422 interface can be used to connect additional devices like encoders, sensors and cameras. The
behavior is controlled by the Real-Time Communication Controller.
The female 15-pin D-sub connector provides three input and three output signals:

Pins 8 provides a 5 V power supply for RS-422 encoders.
The input and output signals use the GND pins as reference potential. Make sure that connected devices
use the same GND reference.
