Connecting Equipment To A Serial Port; Figure 24. Port 1 Pin Assignments - Powerware 9315 Operation Manual

Connecting Equipment to a Serial Port

You can connect a wide variety of terminals, printers, and computers to each port,
and configure the UPS as the Data Communication Equipment (DCE). 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 should be male. Figure 24 shows the pin assignments for Port 1, and
Table 2 describes them. Figure 25 shows the pin assignments for Port 2, and
Table 3 describes them.
