I have a Mecer Model ME-2000-VU+ UPS. Why does the ViewPower software Ver. 2.13 not show the UPS Rated VA and Rated Output Current in Amps on the Monitored UPS Information screen (USB ID=ED)?
It's possible the application doesn't have full support for this UPS, unless the proper drivers are installed. I recommend checking the official website where you can download the drivers for the product. Once you installed the drivers, re-install the software and check the values. If after this process, still doesn't work, then the application doesn't fully support the UPS.

I have a njoy horus plus 2000 ups that I can't manage with viewpower via lan or internet! It works directly from the laptop via a USB cable, but not in a network via a LAN cable
