Serial Communications
15.1 Description
This chapter describes the serial communications feature of the Powerware
9315---750 UPS. Two serial communications ports on the UPS allow you to
connect equipment to view system event information.
The following sections describe the serial communications feature, and provide
information about connecting hardware, setting up the ports, changing settings,
and changing modes.
15.2 Locating the Communications Panel
The Customer Interface Panel inside the UPS contains two serial communications
ports, one DB---9 and one DB---25. The ports provide a computer interface to a
Remote Monitor Panel (RMP), Relay Interface Module (RIM), Supervisory Contact
Module (SCM), or remote terminal and/or printer. The Customer Interface Panel
also contains a 120 VAC, 0.2A convenience outlet for powering a modem used for
remote notification. Refer to Appendix A for location of the Customer Interface
Panel inside the UPS.
15.3 Connecting Equipment to a Serial Port
The UPS is designed to accept a wide variety of Data Communication Equipment
(DCE) such as terminals, printers, and computers to each port. Set up the remote
equipment using the appropriate parameters for the mode you select. The
following section provides more information about configuration.
The cables you use for connection depend on the equipment you are connecting
to the UPS. Cables should be no longer than 16m (50 ft). The connectors for
Port 1 and Port 2 on the Communications Panel in the UPS are female, so the
cables into the UPS should be male. Figure 15---1 shows the pin assignments for
Port 1, and Table 15---1 describes them. Figure 15---2 shows the pin assignments
for Port 2, and Table 15---2 describes them.
