UPS Monitor through LAN

ardly:
Is this an old UPS I could not find it on theCyberPower website?

I found a user manual here;

At first glance this UPS does not seem to have either a serial or ethernet interface, there don't seem to be relay contacts either. Unless you can find that it does have an interface remote monitoring and control are not readily possible.

Here the link where you can find the details- CyberPower UPS Systems, Battery Backup, PDUs, USB Surge Protectors

In my opinion have any procedure where we check current battery voltage through ARDUINO or Input AC Voltage?
