11. Communication Port
11.1 RS-232 and USB communication ports
To establish communication between the UPS and a computer, connect a
computer to one of the UPS communication ports by using an applicable
communication cable.
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 the serial communication cable that comes with the UPS to
the RS-232 port on the UPS. Connect the other end of the serial cable to the
RS-232 port on a computer.
The cable pins for the RS-232 communication port are identified in the
following illustration.

11.3 USB port
The UPS can communicate with a USB-compliant computer by using
HID-compatible power management software. To establish communication
between the UPS and a computer, connect the USB cable that comes with the
UPS to the USB port on the UPS. Connect the other end of the USB cable to
the USB port on a computer.
11.4 Installing a Serial Network Management Card (optional)
Each UPS has one available communication bay, which supports the optional
Serial Network Management Card. After you install a Serial Network
Management Card, you can connect an environmental monitoring probe to the
UPS.
