DB9 Settings
(Input pins 3&9)
• Shutdown (factory setting)
• Output off
• Reboot
• Output on
• Power Toggle
The UPS will perform the selected
action when pins 3&9 are shorted on
the DB9 port for at least 3.8 seconds.
For the Reboot option (output off for
30 seconds before reboot):
The pins must be shorted for at least
3.8 seconds to perform the reboot.
The reboot happens at exactly 3.8
seconds. If the pins continue to be
shorted for more than 3.8 seconds,
no further action should be taken.
The UPS takes no action on release
of the short.
The Power Toggle option is intended
to keep the unit powered on
whenever the pins are not shorted
and powered off whenever the pins
are shorted. This input cannot power
on the unit from an off state unless
valid AC is applied (this function will
not impose a cold start). To power
on, the pins must be not shorted for
at least 3.8 seconds and AC must be
valid. To power off, the pins must be
shorted for at least 3.8 seconds.
