Ekrano integration with Xantrex Freedom X and RVC Combox and Southwire rvc40430 Transfer switch

Greetings: I am contemplating installing and Ekrano GX and want to integrate a Xantrex Freedom 2000 using their ComBox (Adapter) which outputs RVC and the output from a Southwire RVC40430 Transfer Switch which also outputs RVC to a standalone Display. The Xantrex Combox will allow the OEM Remote Display to still be attached and usable for programming and also output RVC to a “Display” Device. The Southwire RVC Output just goes to a display with roating output showing what the source is – Shore Power/Generator - Freq, Voltage and Current on L1 and whether or not there are any errors. There will also be a Victron 100/30 MPPT controller and potentially a smart shunt in the mix. Any info or guidance would be appreciated before i dive in. I am a retired BSEE and BS CS with over 30 years of process and control systems so I can grasp any content.
