1C Dry contact communications are simple, but some
knowledge of electronics is necessary to configure them. The
DB9 port's pin assignments are shown in the diagram. If the
UPS battery is low, the UPS sends a signal by bridging pins 1
and 5. If utility power fails, the UPS sends a signal by bridging
pins 8 and 5. To shut the UPS down remotely, short pin 3 to
pin 9 for at least 3.8 seconds.
