Foxtech Halo 6000 information

I saw that from Arducopter 4.5.0, there is a Lua script for communicating with the the Foxtech Halo 6000 Generator. Other than just extracting the information from the script itself, is there a more detailed documentation explaining the communication, like messages’ IDs, all the information you can retrieve from the generator and others?

I also tried asking foxtech, but they didn’t answer yet.

Does anyone know something?

Can anybody help me with this?
