Fronius IG inverters can only be connected together via the RS 232 interface
Data communication is carried out via DATCOM components such as an interface
card and datalogger
NOTE You should only use the interface box for setting up the data network
when using a network of Fronius IG TL inverters. The interface card cannot be
