The RS-232 DB9 serial port connects the UPS system to a workstation or server (cable included). By communicating with the UPS system through this port, Tripp Lite’s PowerAlert UPS management software (included) can monitor and control the UPS system. PowerAlert also serves as an SNMP proxy allowing the UPS system to appear as an SNMP-manageable device on the network.

RS-232 signals and operations include: load level, battery status, battery level, operation mode, AC input voltage, AC output voltage, AC input frequency, internal temperature, set shut-down delay time, enable/ disable alarm and remote shutdown.

11-11 Parallel Configuration Port

The parallel configuration port allows the UPS system to be connected to another UPS system of identical type and capacity for use in a parallel (1+1) configuration for increased capacity or increased fault-tolerance. Warning: Use only the parallel configuration cable that is included with the UPS system. Attempting to use an incompatible cable may damage the UPS systems and create a serious risk of personal injury and property damage.
