L. RS232 Interface (for service purpose)
The Eaton gird-tied PV Inverter is equipped with a versatile
communications interface and can be used with a stand-alone monitoring
software called "Pro Control" to monitor the operating status of a single
PV inverter or multiple PV Inverters through RS485 or RS232 interface.
To active the RS232 interface, the RS485 interface card should be
disabled manually by switching off the SW2 DIP switch as below figure
6.2.16 indicates. Therefore, it is important to know the status of SW2 DIP
switch when service personnel are dealing the communication interfaces.

DB9 socket is stated as below table shown:
