Q. Could you explain about interface condition, or interface condition of RS232C signal, for Nonstop power supply?

A． Interface condition of Nonstop power supply other than NSP7 series is as follows,
Refer to this in developing Nonstop power supply monitoring software.

Following actions are required to interconnect PC with Nonstop power supply.

1）AC input fail detection signal (=Negative) to be sent to PC from Nonstop power supply when blackout occurs.
2）PC activates the timer to await recovery of AC input upon receipt of the above 1).
3）If AC input is recovered during awaiting recovery of AC input, normal operation is resumed.
4）When recovery awaiting time has passed, shutdown of applications and OS is performed.
5）In the case that Nonstop power supply has sent the signal of DC input fall detection (=Negative) to PC from Nonstop power supply during recovery awaiting time, the action
of 4) above shall be performed without delay.
6）Send all DC output forcible shutdown (=Positive) signal shall be sent to Nonstop power supply from PC at the timing when power shutdown of PC is acceptable.

* In the case that the signal is unable to be controlled at the timing when power of PC can be shut down, shutdown shall be performed by APM (Advanced Power Management).
