Connect your equipment to the UPS jack marked "OUT." Make sure the equipment you connect to the UPS's jacks is also protected against surges on the AC line. * Not compatible with PoE (Power Over Ethernet) applications. Note: Use the same type of connector for the phone line surge suppression input and output ports. 2 USB and RS-232 Serial Communications Use the included USB cable (see 2a ) and/or RS-232 serial cable (see 2b ) to connect the communication port of your computer to the communication port of your UPS. Install on your computer the Tripp Lite PowerAlert Software appropriate to your computer's operating system. Your UPS may feature additional communications ports; these ports may be connected to additional computers that have PowerAlert Software installed. Consult your PowerAlert manual for more information. 2c RS-232 Dry contact communications are simple, but some knowledge of electronics is necessary to configure them. The RS-232 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. Additional functions of these pins can be configured through the LCD or via SNMP card communication. 1 Your model may differ. 2a Your model may differ. 2b Your model may differ. 2c 19
