UPS communication port
This port has two inputs used to monitor and report UPS status.
Recommended mating terminal block connector:
Tyco Electronics
p/n 284507-4 or p/n 284509-4
Pin-out:
pin 1 – 0V(logic ground)
pin 2 – PCS200 Input #4 (Battery Low)
pin 3 – 0V (logic ground)
pin 4 – PCS200 input #3 (Power Failure)
Input #3 and #4 status and log can be viewed with web interface by clicking on “I/O Control” link.
Most smart UPS devices have standard serial port (female D-SUB 9) with status information.
