Try to identify the circuit they have used (u may open it at will)
please do contact the customer care (if one is there!)

Which buying the UPS they will provide one cable which connects to the COM port of the CPU ... take it and connect it and then install the drivers and software which is given by manufacture while buying...
then it should work.......
