Abstract

An uninterruptible power supply includes a multipurpose data port that facilitates a plurality of communication methods including USB, serial and other communication methods, between the uninterruptible power supply and a host computer system. The multipurpose data port is configured to prevent interference if a user mistakenly connects a phone line or other similar but inappropriate line to the uninterruptible power supply. The multipurpose data port reduces the machine footprint needed to support multiple communication ports.
