LetzKey UPS Event Monitoring Software is the missing link between your IT configuration and your Trust UPS : it allows to monitor locally or remotely your UPS and to define an adapted emergency process in case of a power failure and an appropriate restart process that will be launched after a user-defined delay allowing to make sure that the power situation is stable again. This software on a host computer communicates with a Trust UPS using its RS-232 serial port to detect power failures. It can also communicate with a VM110 USB Input/Output card from Velleman. This program exists as freeware and as a subscription-ware with very affordable subscription fees.
