HP PowerWise L600/L900/L1250 interface pinout

Pin#	Signal Type	Function
1	RS-232 Earth Ground	Signal Common for all RS-232 port signals (earth ground referenced)
2	RS-232 Transmit Output	Serial communication mode - output signal line.
3	RS-232 Receive Input / Shutdown	Serial communication mode - input signal line. Contact Closure mode - shuts down UPS if signal is held high (RS-232 level) for 200 milliseconds while UPS is operating in battery mode.
4	AC Line Fail (normally closed)	Contact Closure mode - opened when AC line fails and UPS is operating in battery mode (breaks connection between Pin#4 and Pin#5).
5	Contact Closure Common / RS-232 Common	Signal Common for all Contact Closure group / RS-232 Signal Common line.
7	Low Battery (normally open)	Contact Closure mode - closed when remaining "on-battery runtime" drops below the under-defined time limit (makes connection between Pin#7 and Pin#5).
