Communication Options
The Eaton 9355 UPS 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 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:
Note: You can configure relays, signal inputs, and the serial port baud rate through the front panel menus
(see Table 7 on page 70).
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 40 and the pin functions are described in Table 2. See Figure 36 on
page 51 for the communication port location.

Gateway Card - provides a data gateway from the UPS to the Power Xpert Software; provides
remote monitoring through a Web browser interface, e-mail, and a network management system using
SNMP; connects to a twisted-pair Ethernet (10/100BaseT) network. Modbus TCP support provides direct
integration of the UPS's parameters to a Building Management System (BMS). It has a built-in switching hub
that allows a second network device to be connected to the network without the requirement of an
additional network drop.
