NOTE 1 You can configure relays, signal inputs, and the serial port baud rate through thefront panel menus (see Table 3 on page 28).NOTE 2 The communication speed of the USB port is fixed at 9600 bps.CommunicationEaton 9130 700/3000 VA UPS User’s Guide 164201718—Rev 7 www.eaton.com/powerquality 39RS-232 and USB Communication PortsTo establish communication between the UPS and a computer, connect your computer to one of the UPScommunication ports using an appropriate communication cable (not supplied). See Figure 18 for thecommunication port locations.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 poweremergency occurs, the software initiates the saving of all data and an orderly shutdown of the equipment.The cable pins for the RS-232 communication port are identified in Figure 19, and the pin functions aredescribed in Table 6.387916 245Figure 19.

When the condition no longer exists, the output signal returns to Low.Connectivity CardsConnectivity cards allow the UPS to communicate in a variety of networking environments and with differenttypes of devices. The Eaton 9130 has one available communication bay for the following connectivity cards (seeFigure 20):l Network Card-MS (replaces 103006826 and 66102) has SNMP and HTTP capabilities as well as monitoringthrough a Web browser interface; connects to a twisted-pair Ethernet (10/100BaseT) network. In addition,an Environmental Monitoring Probe (EMP) can be attached to obtain humidity, temperature, smoke alarm,and security information.
