RS-232C

The RS-232C serial communication interface is available through a DB9 female
connector located on the backside of the UPS (see Section 9 for DB9 connector
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.
