Interface Port 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
Reserved.
Pin 7
Remote Shutdown: Shorting this pin to common for at least 5 seconds, while the UPS is
operating on battery, shuts the UPS off after 120 seconds. NOTE: The shutdown
sequence must continue even if AC line returns during the 120 second countdown.
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
Normally open bypass switch status contact. A normally open contact that closes
(pulls to common) whenever the UPS is in an Internal Bypass mode or is being
bypassed through the use of a bypass switch.
Contacts consist of open collector circuits capable of switching up to +30 VDC, 6 mA resistive
load. The internal pull-up voltage on pins 3, 5, 8, and 9 is +12 VDC.
An Emergency Power Off (EPO) function is available through the interface port. Contact SOLA
for specific technical details.
