Db-9 Communication Port; X-Slot Cards - Eaton BladeUPS User Manual

NOTE 1 You can configure relays, signal inputs, and the serial port baud rate through the
front panel menus (see Table 12 on page 95).
NOTE 2 In a UPS connected to utility power, X-Slot cards remain powered on even if the
input breaker is off.

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 73 identifies the cable pins and Table 17 describes the pin functions. See Figure 71 on page 107 for the
communication port location.
