Diode D20 purpose?
D20 separates Field GND from PGND.
- Why?
- Is it recommended for the CLT-01 or the VNI8200XP or both?
- What is the probable drawback of connecting the 2 nets without this diode protection?

Hello
the diode is used only for reverse polarity protection. it is not necessary for a correct ICs functionality
