Driver for Tripp-Lite SmartOnline (SU) UPS equipment

Synopsis

tripplitesu -h

tripplitesu -a UPS_NAME [OPTIONS]

Note

This man page only documents the hardware-specific features of the tripplitesu driver. For information about the core driver, see nutupsdrv(8).

Supported Hardware

This driver supports the Tripp Lite SmartOnline family (via the serial port).

Extra Arguments

This driver supports the following optional settings in the ups.conf(5):

lowbatt=num: Set the low battery warning threshold in percent at which shutdown is initiated by upsmon(8). By default, the UPS may not report low battery until there are only a few seconds left. Common values are around 25—30.
command_delay=milliseconds: Set a delay in milliseconds to be applied before each command sent to the UPS. The default value is 0 (disabled). If experiencing intermittent communication timeouts when multiple commands are sent in rapid succession, set this to 1000 (1 second) or adjust as needed.

This delay helps prevent "read timeout" errors when the hardware buffer is not ready to accept new commands immediately after completing the previous one.
