Communications
“SMART” DB9 Port: Your UPS’s DB9 port can be used to monitor and control your UPS using either
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 at the left. If the UPS battery is low, the UPS sends a signal by bridging pin 1 and pin 5. If utility power fails, the UPS sends a signal by bridging pin 8 and pin 5. To shut the UPS down remotely, send a 5V to 12V signal on pin 3 (using pin 5 as the (negative) ground) for at least 3.8 seconds.
You may connect your UPS to an EPO switch and a computer at once using a Tripp Lite EPO cable (not included; order accessory #73- 0901 from Tripp Lite). Follow the connection procedures included with the EPO Cable.
