EX4100 UPS control

I looked around but couldnt find much so I thought id ask here. I have an EX4100 on a UPS and would like to know if I can have the EX4100 automatically shut down when the UPS reaches a certain battery level. My UPS is not on the network so it would have to be attached via USB.

I have an older APC Smart UPS 1400 with a DB9 serial port and a new Cyberpower 1500

Thats a great link, thank you Jonty. Not sure why I never found that. I wish it would say which ups it supports. I need a new one and would just get one that I know will work.
