In my opinion you would be standing on the north side directly behind the scope and the diagonal with the EP vertical to the OT.
Altitude (Dec) sight a star in the east and rotate the diagonal so that you are standing on the southside of the scope. Why rotate the diagonal? Or am I missing something?
For the southern hemisphere the drift movements are reversed? Do we still use an east star for Dec?

Good luck
EDIT- as far as i know rotating the diagonal would make viewing easier and easier to tell if the star drifts north or south. I choose a star low on the Eastern horizon to set Alt.
