RS-232C Communication Interface
The RS-232C serial communication interface is a standard feature and is available
through a DB9 female connector located on the back side of the UPS (see Section 9.1,
9.2 or 9.3). This interface allows control of the UPS from a personal computer running
special Toshiba software. The computer is connected to the UPS 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.
