Thanks you Jeff a lot for your time!

It seems that somehow the controller process the longitudes such at the those

For the Italian city, longitude is 16, INDI's longitude is 16 as well, Meade 
is sent (360 - 16 = 344), and then Meade internally converts 344 to -16 (that 
is: 16 EAST) 344 - 360 = -16

That's my guess anyway.

Thanks again!
