The RS-232C serial communication interface is available via a DB9 female connector located
under the Remote Eye Cover on the front of the UPS (see Section 4 for location). This interface
allows control of the UPS from a personal computer running special TOSHIBA software. The
computer and the UPS are connected through a serial RS-232C communication port. The
available data from the UPS, via the RS-232C communication link is shown below.

UPS Shutdown (via RS-232C)
When the UPS is operating from its internal batteries, a Shutdown order can be sent to the
UPS telling it to turn OFF after a user-specified amount of time. This function can allow you to
stop discharging the UPS batteries after an orderly system shutdown has been completed.
The UPS can be programmed to turn OFF up to 8 minutes after the Shutdown command is
given. This command can be cancelled before the specified time has elapsed by following the
directions listed on the RS232 screen.
