5 USB Port
The USB port built into the UPS provides a RS-232 serial over USB connection. This allows a serial data stream for computers and
laptops that do not have the standard DB9-type serial port common with RS-232 connections. Once configured in Windows, this
port displays and operates as a standard COM port.
