Is the azbox s810bbb the same as azbox s810b? I do not want to load the wrong file.

I am new to Azbox and bought it already programmed. My concern is; if this box goes 'down' would i need to flash it with the new file only or would I need to key in new keys? The question I'm really asking is; how do I get this stb up and running? I'm looking for the instruction guide (how to section) for the Azbox S810B.
