9.1 RS-232 and USB Communication Ports
To establish communication between the UPS and a computer, connect
your computer to one of the UPS communication ports using an
appropriate communication cable.
When the communication cable is installed, power management
software can exchange data between you computer and the UPS. The
software will obtain the detailed information of the UPS on the status of
the power environment. If power emergency occurs, the software
initiates the saving of all data and an orderly shutdown of the equipment.
The cable pins for the RS-232 communication port are identified in figure
9-1, and the pin functions are described in Table 3.
