Dear Rolando,

First of all thank you very much for your fast and detailed response.

If I work with the keypad installed (no EXT), everything is fine - no
problem with pier flips and pointing - therefore the information for
initialization seems to be ok.

You are right, the problem seems to be the "EXT" setting - the software
seems not to send the right data to the mount, if any...

Therefore I will follow your advice and resist the temptation to
complicate things with the soft...

Thanks again!
All the best,
Christian
