Hi @j4nd3r53n 

Thanks for posting in our business forum.

There is no "correct" User Guide. The interface is universal but has minor differences in the ports. The overall mechanism is the same and applies to all the models. 

This is to say that the User Guide would be universal across the models.

So what do you mean the bandwidth control and what's the big difference? Please specify.

The question is unclear and I have zero suggestions or recommendations.
