DB-9 Pinouts
Pin 1
RS232 Receive Data: Receives incoming RS232 communication data.
Pin 2
RS232 Transmit Data: Sends outgoing RS232 communication data.
Pin 3
Normally Open On-Battery Contact: A normally open contact that closes 15 seconds
(pulls to Common) after the UPS switches to battery power.
Pin 4
Common: The signal ground for all signal pins.
Pin 5
Normally Open Low-Battery-Alarm Contact: A normally open contact that closes
(pulls to Common) during a Low Battery Alarm. This tells CheckUPS II and other
shutdown software when to start a computer shutdown.
Pin 6
Plug and Play Sense for Windows 95.
Pin 7
Remote Shutdown: Connecting this pin to Common for at least 5 seconds, while the
UPS is operating on battery, shuts the UPS off after 120 seconds.
Pin 8
Normally Closed On-Battery Contact: A normally closed contact that opens
15 seconds (releases from Common) after the UPS switches to battery power.
Pin 9
Unused.
Contacts consist of open collector circuits capable of switching up to +30 VDC, 6 mA resistive
load.
