5 COMMUNICATION
5.1 USB PORT
The USB port is a plug-in interface port 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.
For more information please refer to the user manual that comes with the interface software. We strongly recommend to
use only original GE Digital Energy software products in combination with the interface port.
NOTE
The change of some settings can cause the unit to switch from bypass to standby and output power is lost.
5.2 RJ11 PORT
The RJ11 port is a plug-in contact interface port.
