4.1 RS232 Port (fig. 8)
The RS 232 Port is a plug-in interface port (9-pin, Sub-D, male) which enables advanced communication
between the UPS and the computer (UPS software required). The interface port is operative as soon as
the mains power cord is plugged into a live wall outlet, even if the UPS is switched off.
We strongly recommend to use only original
GE Digital Energy
software products in combination with
the interface port.
