In a quick internet search, I found This Site for a company which used to sell it and which had a short description, part of which is below:
"...Once the uninterruptible power supply (UPS) is installed, it will constantly monitor the mains supply and switch to battery power and enable the system to be shut down without data loss. The included software can even be set up to save your data and close down your computer automatically if the power fails while you are away from your desk. ..."
If you originally installed the provided software, it should still be on your system. I found a (pdf.) manual for what looks like a very similar model (link Here), which says the following about the computer connection:
"USB communication port and software
Digitech Pro comes with a CD and USB cable, you can connect your Digitech Pro UPS
to your PC via the USB port. When you load the software to your computer (Windows,
Linux or Mac compatible), you can monitor your UPS from your monitor or you can
program your UPS on how to function in case of a power failure. Digitech Pro is a
smart UPS and can be controlled through your computer or it can make a orderly
shutdown by saving all your application data, closing your software and shutting
down your operating system and finally shutting down your computer."
BTW, it's always good to copy and paste links like that into a new tab, just to be sure what they actually say before opening them.
