Do you have a source for the manual? - it's not the same as the two I already have and may contain more detail. The manuals I have don't show pin numbers for the CN3 port for instance.
In your manual when you read it carefully here and there is mentioned about some sub manuals, like the one i linked to. Or just do a careful straight google search for the thing you have not clear. i have 2 manuals for my Samsung servos, and they are slightly different.
