11. Communication

11.1 RS-232 and USB communication ports

To establish communication between the UPS and a computer, connect the
computer to one of the UPS communication ports by using an applicable
communication cable (not included).
NOTE:
Only one of the communication ports can be active at one time. The USB port has
priority over the RS-232 port.
When a communication cable is installed, the power management software can
exchange data with the UPS. The software polls the UPS for detailed information
on the status of the power environment. If a power emergency occurs, the
software initiates the saving of all data and an orderly shutdown of the equipment

11.2 RS-232 port

The RS-232 port is available for UPS monitoring, control, and firmware
updates. To establish communication between the UPS and a computer,
connect one end of a serial communication cable (not included) to the RS-232
port on the UPS. Connect the other end of the serial cable to the RS-232 port
on the computer.
The cable pins for the RS-232 communication port are identified in the
following illustration.
