Communication Port Configurations
To establish communication between the UPS and a computer, connect
your computer to the UPS communication port using the supplied
communication cable.
C A U T I O N
To prevent damage to your equipment, connect only a factory-supplied cable or a
cable built to factory specifications (see Table 2) to the communication port. A
standard serial cable may damage your computer.
When the communication cable is installed, 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.
Communication Indicator
When the UPS receives a command from the computer to establish
communication, the Communication indicator on the UPS front panel
illuminates (see Figure 14 on page 14). When data is transferring, the
Communication indicator flashes.
