4.5.2 RS-232C
The RS-232C serial communication interface is available through a DB9 female connector
located on the backside of the UPS. This interface allows control of the UPS from a computer
network running Toshiba RemotEyeII™ 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:

4.5.3 UPS Shutdown (via RS-232C)
When the UPS is operating from its internal batteries, a 'shutdown' order can be sent to the
UPS instructing 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 RS-232C screen.
