Advanced port
pin assignments
The Advanced port of Share-UPS has the same limitations
and capabilities as the Basic port (see “Basic port pin
assignments,” on page 54). The following additional limita-
tions and capabilities apply to the Advanced port:
• Applying a momentary (approximately 1 second)
high RS-232 level to Pin 7 turns on the UPS and its
loads. A momentary low RS-232 level turns off the
UPS and its loads. Pin 7 should normally be uncon-
nected. This signal is passed through Share-UPS.
• DC operating voltage is available on Pin 8 of the
Advanced port. This voltage may be the UPS battery
voltage or the voltage from an external adapter,
whichever is greater.
