Mode-S Beast & Custom Image

I am trying to connect my Mode-S Beast to the custom image. Can someone please provde information on how to get the ADSB Exchange 1090mhz decoder to connect to the Mode-S Beast. I have radsb installed on another rpi and my Mode-S Beast connects with the following; however, the custom image will not allow the beast to connect and display data. --device-type modesbeast --beast-serial=/dev/ttyUSB0 --beast-baudrate=3000000 --beast-modeac --net-connector 127.0.0.1,30004,beast_reduce_out"
