The Powerware 9355 has serial communication capabilities through the DB-9
communication port or through an X-Slot card in one of the available bays. In addition,
the Powerware LanSafe Power Management Software can be installed and used to
communicate with the UPS via one of the serial communication connections.
The UPS supports two serial communication devices according to the following table:
Independent
X-Slot 1
Any X-Slot card
Any X-Slot card
Any X-Slot card
NOTE You can configure relays, signal inputs, and the serial port baud rate through the front panel menus
(see Table 7 on page 69).

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.
The cable pins are identified in Figure 36 and the pin functions are described in
Table 2. See Figure 32 on page 47 for the communication port location.
