The communication port at the back of the UPS may be connected to a
computer. This port allows the computer to monitor the UPS and control the
operation of the UPS in some cases. Its major functions normally include
the following:
• To broadcast a warning when power fails.
• To close the files before the battery is exhausted.
• To turn off the UPS and computers.
Some computers may have a special connector to link this communication
port, or require a special plug-in card, or need a special UPS monitoring
software. Contact your dealer for details of different interface kits.
