700 Communication
701 Communication Options
Best Power offers several methods of communicating with your FERRUPS:
CheckUPS Software: Each FERRUPS unit ships with CheckUPS power monitoring and unattended
shutdown software. To begin installing CheckUPS, see the instructions in the
CheckUPS CD case.
CheckUPS uses an RS-232 serial link to communicate with the FERRUPS, and it
provides you with up-to-date graphics of UPS power and system data and power
flow. CheckUPS also gives you a complete record of critical power events, and it
notifies you of important UPS or power information. If there is a power outage and
the FERRUPS battery power becomes low, CheckUPS can automatically shut down
your computer system before the UPS Low Battery shutdown to protect your data.
RS232
Communication: You can connect a terminal or a computer with terminal emulation software to the
FERRUPS’ communication port. This allows you to receive information from the
FERRUPS or send commands in order to display and program parameters. For more
information, call the nearest Best Power office.
