Single-Port Module - Powerware 5125 User Manual

Additional UPS Features

Single-Port Module

The Powerware 5125 is factory-installed with a Single-Port Module.
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 21 and the pin functions are
described in Table 1.
