DB-9 Communication Port

To establish communication between the UPS and a computer, connect

your computer to the UPS communication port using the supplied

communication cable.

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.

Figure 23 identifies the cable pins and Table 3 describes the pin

functions.
