FTS 502
December 23, 1996

This FTS explains how to communicate with standalone LI 520, 720, 1020, and 1420 Fortress models using the DB9S communication port. (This FTS is not for rackmount models.) This document provides information for all Fortress software versions through 1.00.

Fortress includes a free CheckUPS^® II Suite software package for power monitoring and for automatic shutdown during long power outages. If you are planning to use this software, see the instructions and the online manual you received with the CheckUPS II CD.

This document begins with a list of ways you can use the RS232 port. It then describes how to set up full-duplex RS232 communication between your computer and Fortress so you can send commands and receive messages from the UPS. This document also explains how to use the commands and Fortress' parameters to control Fortress operation or to display information about the Fortress and power conditions.

If you have any questions about Fortress communication, call the nearest Best Power office, or call Best Power's Worldwide Service at 1-800-356-5737 (U.S. and Canada) or 1-608-565-2100.
