                Accurat Flux 850 UPS with NUT on Linux (Richcomm V2.0, USB ID 0925:1234) – driver build + master/client setup scripts
              
          
        
      
        

      
      
    Quickstart: Accurat Flux 850 / Richcomm V2.0 NUT Setup

For any UPS with the Richcomm V2.0 USB chipset (USB ID 0925:1234) — including models from Accurat, Vultech, Armac, Hikvision, and ExeGate.
1. Build the driver (on the USB host)

On the Linux host connected to the UPS via USB, compile and install the driver. The standard Debian NUT package (2.8.0) does not support this chipset.
